Description

The vacuum press "PV-1425" is equipped with modern quartz-halogen thermal heaters with a total power of 20 kW, so it provides uniform heating of the entire working surface in a matter of seconds. The film is warmed up so quickly that in practice the productivity of vacuum presses "P V-1425" is limited only by the speed with which the shop workers place the workpieces of the facades on the work tables. Compared to outdated thermo-vacuum presses on spiral heating elements, vacuum presses are able to work even with high-gloss films, consuming several times less electricity.

All membrane vacuum presses "P V-1425" are favorably distinguished from analogous models by the use of an electronic soft start system for heaters and the presence of automatic and manual stepless regulation of heating modes, which expands the functions of vacuum presses and extends the service life of heating elements.

Carefully selected mutual arrangement quartz-halogen heaters and the function of stepless stepless adjustment of the heating power allows the vacuum press to efficiently and quickly fit any types of PVC films: matte and high-gloss, including particularly stubborn, difficult-to-operate PVC films made in Korea and China with a low content of plasticizers ...

Due to the high productivity of the vacuum system (1570 liters per minute) the thermo-vacuum press "PV-1425" can perform all its functions without receivers. Convenient ergonomic clamps of the clamping frame of the working table of the vacuum press significantly speed up the process of laying out the workpieces of furniture fronts and MDF door covers. The cover of the thermomodule of the vacuum press "P V-1425" makes it possible to bend radius MDF facades using bent-glued technology with the help of a silicone or rubber membrane: concave, curved, concave-curved in one tab.

The maximum workpiece height (chord of the radius facade), with which the vacuum press works, is 350 mm. A silicone membrane or a rubber membrane, purchased from us separately, significantly expands the capabilities of a membrane vacuum press, although it is important to remember that facades are clad with PVC films on vacuum presses "PV-1425" without a membrane.

With the help of a vacuum membrane, the heat press "P V-1425" can laminate surfaces with textured finishing materials, veneer them with laminated paper, natural veneer and acrylic. Lamination of MDF furniture facades from the reverse side to match the PVC film on the front side can significantly increase the cost of the facades while reducing their cost.

Features of execution

Each furniture or door production has its own individual characteristics: a certain set of standard sizes of flat facades or door leaves, radii and heights of the chord of curved facades, and so on. Therefore, sometimes manufacturers have specific requirements for the equipment ordered for the production of furniture or doors.

The manufacturer, at the request of its customers, produces new thermo-vacuum presses "PV-1425" with different from the standard dimensions of the working table and the height of the thermal module cover. For example, an increase in the length of the working table allows one more fronts to be clad in one tab or to produce doors for cabinets with increased height. The height of the thermal module cover determines the distance from the heaters to the surface of the desktop, which means the maximum chord height of the workpiece of the bent-glued facade, which can be faced with PVC film in a vacuum press.

Vacuum presses "P V-1425" with increased thermal module height work with radius facades with a chord height of 350, 450 mm. Of course, such changes in the design of a vacuum press require calculating the power of the heaters, and the time of hot pressing for high-quality lining with PVC film has to be increased.

Thermal vacuum press for laminating with PVC film

The process, which is called vacuum pressing, is a work in which uniformly distributed pressure presses the hot film against the workpieces prepared on the work table. In this case, the temperature that the film receives helps to activate and strengthen the adhesive layer.

Thus, the technology of vacuum pressing can safely cover the most difficult and deep profiles of molded products (as well as details of the facade interior) with polyethylene film (PVC). Thanks to this technology, we are able to produce continuous profile lines, and even supplement products with rounded shapes. As a result, the surfaces of products become more wear-resistant, and the service life of the product increases significantly.

There is also the possibility of 3D lamination of facades. PVC film, as soon as it is heated, becomes very plastic and takes the required shape. As soon as it cools down, the form taken before is retained. Facade lamination equipment is based on this type.

What kind of press are there?

- Vacuum presses, our company has developed

- Overpressure presses, our company can make this type of press

Differences in price and design:

Thermal vacuum presses are more common and have a lower cost. They are easier to operate.

Overpressure presses are more complex and expensive.

Both of these presses have the option of additional equipment with a membrane to be able to press porous materials or veneer, and for lamination with PVC film, the membrane is practically not used.

Comparison of pressure in a vacuum press and a press with overpressure:

Overpressure presses are capable of pressing parts at a pressure of 1 - 8 kg per square centimeter, while vacuum presses can produce a pressure of no more than 0.8-0.95 kg per square centimeter. However, it should be noted that in practice, pressure up to 1 kg is sufficient for most lamination procedures. The only exception can be the covering of complex parts with veneer. With a material such as veneer, the recommended pressure should be at least 3-7 kg per square centimeter (in this case, a press with overpressure would be the best solution).

How does a vacuum press work?

The design of the press mainly consists of a box, a frame with a table on which the workpieces are placed. There is also a heater used for heating the film and a vacuum system. It provides equal pressure on the PVC film by applying atmospheric pressure or by injecting excess pressure.

What the process of laminating with PVC film looks like using a vacuum press:

Lamination process with PVC film of MDF furniture facade

1. An adhesive layer is applied to the blanks. Further, with the help of special pads, the workpiece is laid out on the plane of the desktop. The linings have the size of the part, due to which the full stretching of the film is ensured, and the PVC better fits the product. For the same purpose, special technological deviations (gaps) are used.

The figure shows a working table on which the workpieces are placed, which in turn lie on the pads

2. A PVC-film is fixed over the entire surface of the table (special clips are used). Further, it is compressed along the relief of the workpieces due to the injection of vacuum under the film (in vacuum presses). In rare cases, a membrane is used.

3. Now it is time to heat the film. With different designs of presses, various options for the principles of placing the table and the heater itself are possible. In some cases, a table is a movable element, in some a heater.
According to the principle of the press device, they are distinguished into contact and non-contact. In the first case, the PVC film is in direct contact with the heating element. In the non-contact model of the press, the film, accordingly, does not touch the heater. Another name for this type of heater is infrared.
Ideally, a uniform heating of the film to the desired temperature should be obtained (each PVC film has its own heating rate). In membrane presses, the heating temperature can be from 140 degrees Celsius to 160 degrees.

The heating box of the press is equipped with KGT-1000 lamps, placed in a certain order for uniform heating

4. When the stage of heating the film is passed, a new one begins - evacuation. Or, in other words, the stage of pressing the product. The process is the removal of air between the plane of the desktop and the PVC film stretched over it. Atmospheric pressure begins to act, which with force presses the film heated to the required temperature to the surface of the workpieces. At the same time, the heating temperature makes the adhesive base activate.

Workpieces in the process of evacuation continue to be heated (overheating occurs)

After lamination is completed, we raise the heating box and check the quality of the products received

5. Upon completion of all stages, the cooled workpiece is carefully cut along the contour and freed from excess PVC film.
Now all that remains is to enjoy the result of the work performed.

A vacuum press is an equipment with the help of which you can give various materials the required shape. Its design, as a rule, includes a table, a clamping surface, a heating element, and a pump. It is possible to use a membrane, which is necessary for applying a thin coating. The vacuum press is used in various industries.

Navigation:

Vacuum forming is the same vacuum pressing process, but using softer materials such as plastic. Car dashboards, toys, packaging, mugs and other plastic products are made using vacuum forming equipment.

Vacuum pressing

Vacuum pressing is a process in which bent-glued furniture and interior elements are created and veneered. Today, there are many installations with different capabilities. There are universal installations that are capable of working with film or natural material.

During the pressing process, various tables can be used to fulfill their functions. If necessary, they are equipped with thermal elements that enhance the pressing effect. Plants differ in the level of automation. In factories with conveyor production, fully automated vacuum presses are used.

Vacuum pressing may vary:

• by the design of heating elements;
• the way of moving the heating elements;
• the type of fastening of the removable membrane;
• type of heating module;
• used vacuum pumps;

Thermal vacuum press is one of the most common units in vacuum pressing. He copes with facing the facade of furniture with PVR film, doors with veneer material, as well as the manufacture of bent-glued products, which have dimensions not exceeding the dimensions of the press.

A system in which a vacuum bag is present is often used. This is due to the strong different properties of materials, which can be natural and artificial. In addition, different temperatures can be applied when working with PVC films. The operation is especially important when performing 3D pressing, when it is necessary to ensure the elasticity of the film.

Plastic vacuum forming

Vacuum forming of plastic is a process in which products and thermoplastics are manufactured. These are acrylic, polyester, PVC and other polymers. Vacuum is used to change their shape, as well as high temperature. Vacuum forming, as a rule, is a batch production of products. At the same time, there are small installations with which you can create a small souvenir or other similar product.

Vacuum forming of plastic is actively used:

• when creating elements of outdoor advertising: logos, three-dimensional letters and other elements;
• in the manufacture of equipment for trade: front and side panels, shelves, trays, baths, lids and other elements.
• when creating elements of cars: moldings, plastic parts of the panel, boxes for tool boxes and many other products;
• when creating household products: aquarium lids, garbage containers;
• when creating interior elements: figurines, furniture items;
• while creating component parts medical installations: consoles, containers, baths;

Objects made by vacuum forming are present in large quantities in every person's life. This technique is one of the most ambitious today and is used in almost all industries.

Membrane vacuum press

A membrane vacuum press consists of the same elements as other types of installations, with the exception of one - they have a membrane. The manufacture of bent-glued products using a vacuum press looks quite simple from the side. To do this, it is necessary to place the object on a special table surface, taking into account that it will already be coated with glue with a film, and close it. Next comes the setting of the necessary temperature and time parameters, which the specialist appointed for the operation should know. Often a membrane is used for greater density.

The membrane vacuum press can also work in cold mode. In this case, a special bag is used, which will play a decisive role in quality. The properties of the material from which the bag is made determines how well the operation will be performed. As a rule, bag manufacturers make sure that the products are durable, elastic, and transparent.

At the same time, it is important to use professional bags that can be reused. They will not rupture under the influence of temperature and in vacuum. With their help, you can perform various pressing work, since they are not afraid of heavy loads.

Vacuum press for MDF facades

The thermal vacuum press is the installation that is best suited for the MDF facade. In our country, there is a large number of installations of this type, capable of performing tasks of varying complexity. Choosing a vacuum press for an MDF facade is always a difficult process, since you can easily get confused about the characteristics and other basic indicators.

The first thing to look for when choosing a facade press is the size of the installation. There is nothing complicated here, the main thing is that the workpieces fit easily in length, width and thickness. It is advisable to make some gaps, since it will be simply impossible to increase the size of the equipment.

Next comes the design of the working unit. The best choice would be a movable heating carriage mounted on rail guides. Using it, you can process MDF facades from all sides.

The choice of the thermal module is equally important. The best option there will be a lifting theme module, which is attached to the hinges. This design is effective because it saves working space in production. At the same time, it becomes much more difficult to lay the parts and stretch the foam.

Today, many enterprises are switching to membrane vacuum installations, which have vertical pneumatic or hydraulic lifting of the heating module.

Vacuum pump for vacuum press

Vacuum pump for vacuum press is one of the main elements. The performance of the vacuum press depends on how high the performance indicators will be, and what maximum residual pressure the installation can create in the equipment. Naturally, the heating elements must correspond to the characteristics of the speed of response, otherwise all the technical capabilities of the pump will be used in vain.

For a vacuum pump, most often, vane vacuum and liquid ring vacuum pumps are used. Installations have high specifications and are excellent for performing vacuuming operation in pressing equipment.

The main parameters for the selection of a vacuum pump for a vacuum press can be considered:

• the possibility of using the unit in high temperature conditions;
• the principle of operation of the unit and the materials used for lubrication;
• parameters of the generated pressure and speed;
• the purity of the operation;
• dimensions;
• noise and vibration;

Rotary vane pump vacuum

The rotary vane pump is a versatile means of creating a vacuum, so it is not strange that it can be used in a wide variety of installations where low, medium or high vacuum is required, including pressing equipment.

Today, there are many different modifications of this type of model. At the same time, the main distinguishing feature of vane vacuum pumps of similar performance is the fact of using or not using vacuum oil.

Oil-immersed vacuum plants have a higher productivity, since there are practically no gaps between the main moving structural elements. They are sealed with vacuum oil. At the same time, the vacuum oil can evaporate during operation, thereby contaminating the pumped out air. This fact makes "dry" pumps more preferable for work in a vacuum press.

Units that use removable graphite plates are currently inferior in terms of high pressure capability, but it is most likely a matter of time before they become more popular than oil models.

Water ring vacuum pump for press

The liquid ring vacuum pump is quite well suited for applying vacuum to pressing equipment. He, despite the fact that it has a relatively low performance, is a universal means of pumping out gases of various types.

The liquid ring vacuum pump uses water as the working fluid. It ensures that the unit does not overheat during operation and is self-lubricated. At the same time, contaminated gases, when they come into contact with water at high speed and high pressure, begin to be purified. This makes the unit an excellent choice for a vacuum press where gassing is present.
