A vacuum press is a device that is primarily designed to process various materials. This process is carried out by applying a film that can have a variety of standards. Often, such devices have, in addition to the main one, a number of additional functions. Such installations have found their active application in various industries. But most often, they are used in large industries. As for those industries where the vacuum press has become an integral element, then for sure - this is the furniture industry. This direction simply cannot function without a vacuum press. 
One of the target tasks of a vacuum press is the creation of various figures from wood, plastic and similar materials. Judging by the sales statistics and customer reviews, such equipment is indeed very effective and it will not be difficult to find a use for it. Such equipment is able to easily perform even the most complex functions, and do it very quickly.
It may seem to many that the design of a vacuum press is not particularly reliable. There are a considerable number of reasons for this, the main of which can be called its not quite presentable appearance. But still it is worth saying that in this design all its elements are purely in their place, which actually allows the device to be used with such efficiency.
The main elements of a vacuum press:
- Carriage - this element can be called a kind of adapter for the interaction of all elements of the system. Many consider this element to be one of the most important, as it performs a huge amount of work.
- The pneumatic vacuum system is one of the fundamental elements of this system, which is responsible for most of the labor-intensive tasks. Often, we are talking about the qualitative distribution of pressure in all directions of this device. This is what allows you to create a high vacuum level.
- Desktop - a certain number of devices can be attributed to this element. All of them, although not so significant, still make a considerable contribution to the overall success of the device.
Above, we have listed only the most obvious components of the vacuum system, which can be seen at a glance. But it is worth remembering that inside such a system there are still a huge number of other elements. Although they are less noticeable, their role in the overall workflow is also very impressive.
The vacuum press is divided into two main categories:
- semi-automatic
- Auto
If the semi-automatic principle of operation implies a certain amount of human assistance, then the automatic one does all the operations on its own. But still, at the moment, the semi-automatic principle of operation is very popular.
But to say something about this is definitely very problematic. After all, everyone has their own tasks that need to be solved. But which press is best suited for this, only you can determine.
Membrane vacuum press
This type of vacuum press is intended for use exclusively in the furniture industry. The main reason for this is the principle of operation of the device, which is designed exclusively for the furniture industry. Diaphragm-vacuum pumps come on sale in a variety of configurations. It all depends on how expensive the option is chosen by the user, and how big the task is.
If we talk about the most significant differences between membrane-vacuum pumps, then they simply do not exist. The only thing is more compact dimensions and higher technical characteristics. As for the appearance of the device, in this respect there are no differences as such. Many at this stage are sure that very soon this category of presses will break out to a completely new level, since it is precisely this category that has the greatest potential.
Now, as an example, we will consider the most compact and versatile version of a vacuum press:
Membrane vacuum press VPR-3000 is one of the best models of vacuum membrane presses in the middle price range. Many users at this stage prefer to purchase this particular vacuum pump model. The reason for this can be attributed to the high level of productivity and quality of the vacuum press. As for the place in the market, now VPR-3000 vacuum presses occupy one of the leading positions in the middle price segment.
This was the main reason to turn our attention to this model of the membrane-vacuum press VPR-3000.
Vacuum press for MDF
Facing kitchen and furniture facades is far from the easiest process that requires special equipment. One of the best types of equipment in this regard can be called a vacuum press for MDF. After going through a similar process, the material gets a completely different look, which means that its durability and density increase several times. If this type of processing is ignored, then later all this can turn into far from the best consequences.
Another direction in the work of vacuum presses is the facing of various kinds of materials using a high-gloss film. This type of processing makes it possible to raise the quality level of the material. Absolutely all elements that have undergone such processing become protected from the effects of the outside world. As for the heating of such equipment, this process is also far from the easiest. A significant role in this is played by special heating elements, which are actually intended for this.
Vacuum presses for facades
The facade cladding process combined a number of stages, each of which is responsible for solving a specific problem. Many users say that the facade vacuum press process is one of the most efficient at this stage. Already at the moment, a huge number of different enterprises are ready to give a lot of money to get equipment of this type.
But it should be understood that a vacuum press for facades is only one subcategory of a vacuum press. But this does not prevent him from gaining more and more popularity, reaching an ever higher level.
As for performance indicators, in this regard, everything is no worse. A high level of productivity also depends on how carefully they treat such equipment. But in fact, this is far from the end of the development of this industry and in the future everything can change very much.
But if there are enough advantages in such systems, then it is worth noting the fact that such systems also have their drawbacks. One of them can be called average cooling quality. In certain situations, this element may not be the most reliable, which is why they try to take care of it in advance.
Where to buy a vacuum pump
But you should not pay all attention to only two aspects that everyone considers the most important. Indeed, in addition to characteristics and cost, there are still a considerable number of factors that play an equally important role. One of these indicators can be considered stability, on which a lot also depends in the workflow.
An equally important point can be called the brand that you are going to buy yourself. After all, having bought devices from a trusted person, you can be sure that in the end you can get your money back.
Now, we will look at some of the most reliable manufacturers of vacuum pumps:
- Atlas Copco - One of the oldest manufacturers, which has long established its place in the market.
- Edwards is already a lesser known company. But still, in her circle, she is in considerable demand, which is why many pay attention to her.
- Becker - This manufacturer pays the most attention to the quality of the products sold. Of course, marriage may slip during the manufacturing process, but all this can be fixed with the help of additional equipment that will not leave you in trouble.
The main equipment for the production of MDF facades in PVC film is a thermal vacuum press.Today, a huge number of presses with a wide variety of technical characteristics are presented on the Russian market.Therefore, before purchasing, you should ask yourself a few questions in order to correctly answer the main one - how to choose a vacuum press for MDF facades.
The size of the working surface of the vacuum press for MDF facades
When choosing the size of the working table of the press, the expected volume of production and the range of MDF products should be taken into account. Manufacturers of thermal vacuum presses for the manufacture of MDF facades offer equipment with a working surface of 1150× 1090 mm, such as, for example, a membrane-vacuum press for bent MDF facades from the New Technologies company, Penza. The maximum size of the working table of a vacuum press for facing MDF facades can currently boast of Latvian equipment VP -4000, from ISTRA-A (Latvia), with table 4000× 1400 mm.
Please note that the standard width of PVC film rolls for vacuum pressing is 1400 mm. Some European companies offer films with a width of 1420 and 1450 mm. However, the main manufacturers of equipment for membrane vacuum pressing are oriented towards the 1400 mm standard.
In addition, for continuous flow production of MDF facades, some developers offer membrane-vacuum presses with 2-3 working tables, such as Master PRO, Moscow. The movable heating carriage, moving freely over the working surfaces, provides alternate heating of the PVC film. The structure of the vacuum press can include a table for cladding curved facades.
The design of a vacuum press for MDF facades and its dimensions
With a shortage of working space in the furniture workshop, the size of the vacuum press for the production of MDF facades and the area it occupies will become a natural question. But we should not forget about the convenience of equipment maintenance. Here you should understand the design solutions for the location of the working table and the heating module offered by manufacturers of vacuum presses.
The main manufacturers offer the following options for the design of the membrane vacuum press:
· With movable heating carriage on rail guides. This design of the vacuum press allows you to lay out MDF facades from 3 sides.
· Vacuum press for MDF facades with hinged lifting thermal module. The effectiveness of this design lies in saving the working space of the furniture workshop. However, laying down parts and stretching the PVC film becomes more difficult.
·
With pull-out table for loading MDF and PVC foil parts, such as the vacuum press for MDF facade cladding MTA-2500. Ideal for small furniture production, as it will compactly fit into any corner of the workshop.
· The most effective in terms of workshop space saving and serviceability are membrane-vacuum machines with vertical pneumatic or hydraulic lifting of the heating module, such as the VPF-2 vacuum press from a Latvian manufacturer, or the Italian PM ORMA press, which, among other things, allows to produce facing products with 2 -x sides.
Features of the configuration of membrane-vacuum presses for the manufacture of MDF facades
1. Heating module of the membrane vacuum press . At the current level of development, manufacturers of vacuum presses for cladding MDF facades in PVC film use quartz-halogen thermal heaters that provide fast heating with minimal energy consumption. In other embodiments, infrared lamps may be used. Some manufacturers of membrane-vacuum presses use hot air for heating, supplied through heating elements, to prevent uneven heating on the membrane surface. In addition, additional thermal equipment for heating the table can be installed on the vacuum press. Chinese machine tool manufacturers heat PVC film by pumping hot air underneath it.
2. Automation of the process of facing MDF facades in PVC film . Vacuum presses equipped with automation systems have proven themselves well in in-line and continuous furniture production. Human participation is reduced only to laying the details of the MDF facades on the desktop and then trimming the excess PVC film. However, in small businesses that work daily with a wide range of PVC films, it is easier to carry out the cladding process manually, “by eye”.
3. Silicone, rubber or rubber membrane . Most manufacturers supply a vacuum press for MDF facades with silicone membrane, which has high heat resistance and elasticity. With the help of a silicone membrane, some technological operations are performed for gluing various materials, giving them a curved shape according to a pattern, as well as for the rational use of PVC film with small bookmark volumes. In some designs of vacuum presses, the silicone membrane is mounted on a special frame, which makes it more convenient to use. In other cases, the process of cladding MDF facades in PVC film is based directly on the use of a silicone membrane, and it is an integral part of the equipment.
4. Vacuum pump. As a rule, modern membrane-vacuum presses for MDF facades are installed oil pumps, which currently have the highest performance. With a small size of the vacuum press table and a short pressing time, oil-free "dry" pumps with lower performance. As a budget option, a membrane-vacuum press can be installed VVN water ring pump. With a significant size of the working table of the vacuum press, the vacuum pump can be supplemented with a receiver. Some machine tool builders combine a vacuum supply with a counter-supply of high pressure, so a compressor may be required with the equipment.
5. Dividing frame . It is used when dividing the working table of a membrane-vacuum press for the simultaneous use of two types of film or one, in combination with a silicone membrane, for the rational use of PVC film with a small number of products.
6. Additional desktop . In large-scale production of MDF furniture facades in PVC film, the installation of one additional working table allows increasing the productivity of the membrane-vacuum press and, accordingly, the output by 1.5 times or more.
7. Membrane vacuum press control panel . When crimping MDF facades "in manual" mode, as a rule, two buttons are used to turn on the heating and vacuum pump, as well as a valve that regulates the vacuum supply rate. More powerful and automated equipment requires an appropriate control panel.
8. Possibility of manufacturing radius (curved) MDF facades . In view of the design features, some membrane-vacuum presses do not allow the production of MDF radius facades and their cladding in PVC film. On the other hand, as for example the Master PRO company in Moscow, machine tool builders took care of this option by adding additional devices to their equipment.
9. Unwinders . Including with manual or pneumatic cutting of PVC film. Such equipment can significantly increase the productivity of a vacuum press with large production volumes.
10. Antistatic brushes . Allows to remove a static charge from a PVC film to facilitate its cleaning and eliminate debris sticking to its surface before feeding it to a vacuum press. They are installed in order to improve the quality of the manufacture of MDF facades and other products.
11. Support system. Special supports, including magnetic ones, are used as a substrate when laying MDF facades on the working table of a vacuum press. Some manufacturers even took care of such a “little thing”.
12. PVC Film Waste Briquetting Press, Silicone Membrane Tears and Damage Repair Devices, PVC Film Roll Storage Movable Racks - all this may not be included with a membrane-vacuum press for MDF facades, however, it is often offered by the manufacturer as additional equipment, such as, for example, German designers of vacuum presses BR 2600, Wemhoener. Such devices make the production of MDF facades more convenient and efficient.
Before you finally decide and choose a vacuum press for MDF facades, you should also study the price range, the availability of options for installation and adjustment of equipment, staff training, further warranty and service.
A vacuum press is a unit that allows the production of furniture facades with PVC films and decorative door linings on the basis of MDF. It can be purchased or made at home.
The material will be devoted to how to make a vacuum press with your own hands, and what is required for this.
Remember that such work is quite difficult, you need observe safety rules, because it is associated with the use of power tools of a high degree of danger and heavy structures. If you want to assemble a press with your own hands, evaluate your capabilities, and if it is difficult for you, it is better to entrust this matter to a professional.
Vacuum press: purpose and principle of operation
Film furniture facades are widely used in the manufacture of cabinet or upholstered furniture due to the following characteristics:
- a wide range of colors;
- variety of forms;
- affordable cost.
Such facades produced on special equipment, while the main production tool is a vacuum press. It shrinks a PVC film onto the surface of an MDF-based workpiece.
The press includes the following key elements:
- vacuum chamber or table;
- thermal module.
The chamber most often has a rectangular shape and is made on the basis of a rigid material that does not compress under artificially created negative pressure from the inside. And outside, a PVC film is laid, the edges of which are sealed with the frame.
film shrinking process includes the following steps:
- laying blanks on the table;
- sealing;
- film heating;
- air pumping;
- cooling;
- cutting blanks and removing excess film from the facade.
Do-it-yourself vacuum press: what you need to know?
Before working on the independent manufacture of a vacuum press remember the following:
If you plan the purchase of components and do the work correctly, the cost of a do-it-yourself press will be significantly lower than the factory counterpart, and you can make film facades and MDF lining at home.
Before you start making a bed for the press, you need to pick up optimal type of heating unit, since this will affect not only the design of the bed, but also other elements of the press. When assembling with your own hands, it is best to choose a retractable thermal module, which is easy to assemble and easy to use, but it has large dimensions.
For the manufacture of the bed you will need:
- steel profiled pipe;
- rails for thermomodule.
The bed design is best modeled on a computer using special 3D modeling programs.
Required to work the following set of tools:
- small one-handed angle grinder with a disc diameter of 115 or 125 mm;
- welding machine;
- electric drill;
- locksmith set, including a hammer, wrench, pencil, tape measure, etc.
Assembly steps the stands will be:
- cut the steel profile into parts according to the cutting charts;
- lay them out on a flat surface in accordance with the project, align and fix with clamps;
- tack the joints of the parts, taking into account the final welding on all sides or full welding of the seams without tacks;
- knock the slag off the seams and check their quality;
- if necessary, clean them with a grinder with a grinding wheel;
- drill holes;
- clean the surface with a metal brush from rust;
- prime the surface;
- paint it with a brush or spray can.
For operation, the welding machine can be selected based on AC transformer, inverter type device or semi-automatic device.
The table assembly stage is the most important when assembling a vacuum press with your own hands. At the design stage, decide on its size and material, on the basis of which it will be made, also consider how to fix and seal the connector elements in order to preserve the internal vacuum. Tools for work will require the same as for the bed.
vacuum table is a design that includes the following elements:
- bath;
- clamping frame;
- clamps and other items.
vacuum bath
You need to calculate the size of the bath before assembling it. Remember that the longer it is, the more blanks will fit in it, but at the same time you will use more films in one working cycle. As practice shows, its optimal length is about 2.5 meters.
The width of the structure depends on the width of the applied PVC film, most manufacturers produces products with a width of 1.4 m.
And the working height of the bath should be provided taking into account the presence of a small space between the upper part of the facade and the film with which it will be covered. So, before the air is pumped out, the film should not touch the workpiece.
A 2 mm thick steel sheet is suitable as a bottom for a bath, and a profile pipe is suitable for a frame. The pipe cut in advance must be laid on the slipway, fixed with clamps and boiled all the junctions. A steel sheet must be welded on top of the stiffening frame.
Manufacturing of clamping frame and clamps
We make the frame on the basis of a profile pipe, its dimensions must strictly correspond to the parameters of the bath. To keep the pressure frame up, you need to put 4 gas lifts and make sure they are able to hold it.
Clamps are needed in order to ensure a reliable and tight hold of the film during the pressing process. To do this, the upper frame must be firmly and evenly pressed against the perimeter of the bath. Clamps work on the principle of eccentrics, they can also be made by hand on the basis of rolled steel.
To install them, holes must be drilled at 8 points on the vacuum table. At the same time, the upper ones increase and give them an oblong shape. Further, they are adjusted by installing nuts in the threads of the stud and fixed with locknuts.
If the table does not have a perfectly flat surface, then you need to cut off the welds with a grinder, you do not need to do everything again. Also, to ensure evenness, you can treat the table with special epoxy compounds, setting it strictly according to the level and cleaning the bottom from rust.
Vacuum system installation
A vacuum system is needed to remove and pump out air so that the film can easily fit the surface of the workpieces.
When installing it , keep the following points in mind:
- it is desirable that the system components are not custom-made, and they could always be purchased at retail;
- it is best to choose inexpensive components with satisfactory reliability and ease of use;
- the system must provide the air pumping speed and vacuum depth, which are enough to create standard flat facades and overlays;
- the air removal system should not be demanding on the environment and food quality;
- controls and controls should be simple and inform about the current pressure, also with their help you need to smoothly adjust the speed of pumping out air.
Such a system consists of the following elements:
- water ring vacuum pump with water tank;
- pipeline for delivering air from the table to the pump with a valve and a pressure control device;
- tabletop for pumping air from any point of the table, regardless of the position of the blanks and the film.
Features of the water ring pump and its installation
The pump must have the following specifications:
- productivity 1.57 m3/min;
- three-phase motor voltage;
- electric motor power is 5.5 kW;
- residual pressure 0, 45 mm Hg;
- rotation speed is 1500 rpm.
His the working principle is as follows:
- the impeller rotates eccentrically in the cylinder in the direction of the arrow;
- there is a working cavity between the wheel hub, water rings and the body, it is divided into cells by the wheel blades;
- during pump operation, water is thrown from the sleeve to the housing under the influence of centrifugal force, and the volume of the cells increases and air is sucked in. Then this volume is reduced, and the gas is pushed out through the discharge window during compression;
- in order to maintain a constant volume of the ring and to remove heat, only clean water must pass through the pump. It is supplied to the central hole in the pump housing and discharged through a special device that separates water from gas. This prevents water from being drawn out of the discharge pipe along with the air.
The pump should be installed on a special foundation or in a concrete floor, it should be leveled, then it should be fixed with anchors through standard holes. Next to it you need to put a water tank with a volume at least 30 liters. Two tubes are attached to it, one takes water with a pump, and the second drains the waste liquid into the tank. During circulation, the water is heated, and this negatively affects the operation of the pump. To ensure its natural cooling, the tank must be made of a material that conducts heat well, in particular steel or aluminum.
The pipe supplying water to the pump must be equipped with a tap that can shut off the water when idle. The tank and pump are connected by flexible hoses and fastened with metal clamps.
When you have assembled the pipeline and fixed it to the press frame, installed and connected the pump, you can test the system. For this purpose, power the pump in a timed manner by means of a circuit breaker. But it is better to postpone testing until the moment when the electrician of the press is ready.
How to make a thermomodule with your own hands
The thermal module is a heating device that allows you to evenly heat the film to the required temperature and hold it for some time.
This stage of work is considered the easiest when assembling a vacuum press. For the frame of the thermal module, we need a steel pipe with a cross section of 20 by 20 mm. It will be necessary to weld the cases of profile wheel supports and L-shaped handles to the frame to move along the rails of the module. Wheels can be ball bearings.
Next, the frame is needed sheathed with sheet steel and secure with aluminum rivets. On the side of the casing, it is necessary to cut rectangular openings for viewing windows and insert silicate glasses there, having previously darkened them with a tinting film. Cut one 50mm round hole next to each window, this will be a reference window to measure the temperature of the film, and they must also be equipped with sliding shutters. And in order to improve the reflectivity, the inside of the thermal module must be equipped with aluminum foil.
To create a thermal module we will need:
- exhaust riveter;
- metal scissors;
- spanners;
- press tongs;
- insulation stripper.
Now you need to install the heating elements. Linear lamps KGT (quartz halogen thermal) are suitable for this. They are have a number of advantages:
- affordable price;
- high resource;
- efficient transfer of thermal energy through radiation.
Connecting the lamps according to the wiring diagram is the final stage of assembling a vacuum press. The lamp connection scheme takes into account the requirements in terms of the symmetry of a three-phase load and the possible zonal control of groups of lamps depending on the level of distance from the center of the table.
Now you have an idea about the independent manufacture of a vacuum press. If you decide to take on this job, then do not forget to use personal protective equipment, since it is not only difficult, but also dangerous if safety rules are not followed.
A vacuum press is an indispensable device in the manufacture of furniture and various industries where a person has to deal with MDF, chipboard, elements made of plastic, artificial stone, etc. Additionally, the press is able to give the surfaces of the material a certain relief, which allows you to get products that are original in shape and configuration .
The vacuum press consists of several main elements:
- Frame. Often, this supporting structure is made in a collapsible type, which allows for repair, maintenance, disassembly for convenient transportation;
- Desktop. It is also a supporting structure, which is completed with a special clamping frame;
- vacuum system. This pneumatic system is the main element without which it is difficult to imagine a vacuum press as such;
- Retractable carriage. There is a heating element that is powered by electricity;
- Control automation. Press vacuum drying chambers, doors, carriage, the vacuum system itself operate by means of automatic control. The participation of the operator is minimal, which makes it possible to achieve a higher quality of artificial veneering, manufacturing elements for furniture facades, gluing plastic, chipboard, MDF, etc.
Kinds
The vacuum press is classified according to several main features. Let's start with the level of automation. Depending on this characteristic, devices for pressing wood, facades, plastic, artificial stone are divided into two types.
- Automatic. Here, the presser of wood, artificial stone, plastic performs all operations independently, therefore the participation of the operator is practically not required.
- Semi-automatic. These are more outdated models of wood pressers, since the operator must open the doors of the press chamber, press the buttons to start, turn off, remove the pressed elements from wood, plastic, MDF with his own hands. Their period is gradually coming to an end, since it is more efficient to work with devices where the mold works in an accelerated automatic mode.
Automatic models are more attractive because they require less time to complete the operation. Therefore, the manufacturer can produce more products in the same period compared to semi-automatic plants.
No less significant classification is the division of devices into membrane and non-membrane.
- Membrane installations paste over the surfaces of wood blanks with veneer or special films. In this case, a blank with a pre-applied adhesive is placed in the membrane. The membrane heats up, the vacuum pump pumps out air, which creates a negative pressure. This allows the product made of wood, MDF to firmly contact the film. After waiting for some time, the mold is removed, the workpiece is ready for use;
- Membraneless presses are relevant for those cases when blanks made of plastic, MDF, wood are pasted over with denser films, special coatings. Membrane counterparts perform well with a thinner coating.
With such units as the Master, ST 420, the choice does not become very difficult. But the market is not limited to Master or ST 420 presses alone. Before making a choice, it is worth understanding the varieties, features and nuances of buying this equipment.
In production, two main types of vacuum press are used.
- Standard vacuum unit. This is a device that has gentle characteristics used in the manufacture of furniture elements from MDF, wood, plastic. The main feature of the machines is that the pressure they create is no more than 0.95 kg/cm2. They are used when applying PVC films or veneer to simple furniture blanks.
- With extra pressure. This is more expensive equipment that can create pressures in excess of 8 kg/cm2. It is used to work with MDF, plastic products and elements of complex configuration.
membranes
The membrane is an important element of the machine used for the manufacture of wood blanks, furniture facades. The membrane has certain characteristics.
- The main task is to exclude movement when creating facade elements or furniture components made of wood;
- The membrane allows you to qualitatively apply a thin film on a piece of wood that does not like high temperatures;
- The membrane is installed on special hooks, which are located on the clamping frame;
- Furniture production and MDF facade assembly enterprises use two types of membranes - rubber and silicone. Rubber is used more often, while silicone is more wear-resistant;
- The use of the membrane contributes to the facing of small parts;
- These elements significantly reduce the consumption of the film required for application to wood parts, MDF facades, etc.
Press or bag
Before you buy yourself a ST 420 press or make a vacuum press with your own hands instead of ST 420, you should learn about such a thing as a press bag.
- The press bag is designed for you to make your own vacuum press;
- Its essence lies in the fact that the bag itself is a press machine;
- A product made of wood, chipboard, MDF, prepared for gluing, is placed in the bag;
- The bag is sealed from all sides, which allows to achieve sealing;
- With the help of a pump, air is pumped out of the bag, which allows you to gradually create the necessary pressure, evenly distributed over the workpiece;
- Next, the bag stands in a compressed state for some time, after which the workpiece is removed;
- The main advantage is that the cost of the bag is ten times less than the price of the machine. A press measuring 1400 by 2500 mm will cost the buyer $ 1,000, while a bag can be purchased for 500-1000 rubles. You will not need any drawings to make an effective press out of a bag for creating elements of facades, furniture, etc. We draw conclusions and make a decision.
But the bag is no match for the ST 420. The modern ST 420 is unique because it is a 3D press. Model ST 420 can be used for private business when applying images to T-shirts, mugs, to create covers for tablets, smartphones. At the same time, the ST 420 costs about 70 thousand rubles.
The bag is certainly not capable of what the ST 420 can produce. But the choice is yours.
When choosing a membrane press for the manufacture of facades from MDF, chipboard, furniture elements, pay attention to a few questions.
- Pump. The membrane press can be equipped with our or foreign pump. Italian models are preferred. Although they are more expensive, they are more efficient, reliable and durable.
- Table material. It is best if the desktop is made of metal. A number of models of machine tools are made of chipboard, but they quickly become unusable, the surface is damaged during the manufacture of products.
- Machine dimensions. The main characteristic on which the ability to create parts of various dimensions depends.
- Heater. There are heating elements and KGT lamps. Choose the second type, because they do not burn the film.
Don't forget the manufacturer. Little-known companies should not be trusted. But it doesn’t always make sense to overpay for a brand.
A vacuum press is a unit with a huge number of functions, each of which plays an important role in the system. Such installations are now actively used in a huge number of large enterprises that simply cannot function without such systems. If we talk about the industry where the vacuum press has become a key element, then this is furniture production, which at the moment can no longer do without the work of a vacuum press.
Navigation:
vacuum press- this is an element that is engaged in the creation of certain figures from a tree, enabling further processing of the tree within the system. If you believe the feedback from users from the network, then it is not difficult to guess that such installations are very productive and useful, as they are able to perform a number of important functions that not every unit can handle.
At first glance, such installations seem rather unusual in their external design, but if we take into account the fact that each of the elements performs certain functions, and there is simply nothing superfluous in the system, then it seems that the unusual design of the device is only to its advantage. . To begin with, we will consider what a vacuum press consists of in order to understand how complicated this unit is in terms of operation:
- Desktop- This is an additional element of the system, which includes several small devices that only provide certain advantages during the operation of the unit.
- Carriage- This is an element that constantly interacts with other parts of the device, which subsequently makes it possible to achieve the highest performance in terms of performance
- Pneumatic vacuum system- This is one of the main elements in the system, which takes responsibility for performing tasks of varying complexity. This element does a good job of distributing pressure, redirecting air flows, and similar tasks that play a big role in the formation of a vacuum.
These are just the most obvious elements that can be seen with the naked eye. In fact, such units consist of a huge number of similar elements that somehow affect the operation of the mechanism. The vacuum press is also divided into two categories according to the principle of operation:
- Auto
- semi-automatic
Automatic working principle is a hollow automation system that does not require any person in the workflow.
Semi-automatic working principle- this is almost the same system, only at certain points it requires loading or unloading materials. That is why it was called semi-automatic.
If we talk about which of these options is better, then it is necessary to take into account a huge number of points. In fact, both options are interesting in their own way, because of which, you first need to decide on the purpose of buying such a unit, and after that draw some conclusions.
Membrane vacuum press
A membrane-vacuum press is a device that has far from the smallest dimensions and is most often used precisely in furniture enterprises, where at the moment one simply cannot do without a high-quality and reliable vacuum press. The modern vacuum technology market is already overflowing with a wide variety of diaphragm vacuum pumps, which have not only different characteristics, but also different configurations.
If you look at the cardinal differences between membrane vacuum pumps and other devices of this series, then, in fact, they do not exist. The principle of operation of such devices is very similar and the only obvious difference is the potential of membrane-vacuum pumps, which can soon reach a completely new level.
