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 performance of vacuum presses "P V-1425" is limited only by the speed with which the shop workers lay the facade blanks on the work tables. Compared to outdated thermal vacuum presses on spiral heating elements, vacuum presses are able to work even with high-gloss films, consuming many times less electricity.

All “P V–1425” membrane-vacuum presses are favorably distinguished from analogue models by the use of an electronic soft-start system for heaters and the presence of automatic and manual stepless control 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 smooth adjustment of heating power allows the vacuum press to qualitatively and quickly attach any kind of PVC films: matte and high-gloss, including especially stubborn, difficult-to-work PVC films made in Korea and China with a low content of plasticizers .

Due to the high performance of the vacuum system (1570 liters per minute), the thermal 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 blanks of furniture facades and MDF door linings. The cover of the thermal module of the vacuum press "P V-1425" makes it possible to bend radius MDF facades using a bent-glued technology using a silicone or rubber membrane: concave, concave, concave-curved in one tab.

The maximum height of the workpiece (the 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 facade cladding with PVC films on PV-1425 vacuum presses is made without a membrane.

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

Performance features

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

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

Vacuum presses "P V-1425" with an increased height of the thermal module work with radius facades with a chord height of 350, 450 mm. Of course, such changes in the design of the vacuum press require the calculation of 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 PVC Film

The process, which is called vacuum pressing, is a work in which evenly distributed pressure presses the hot film onto the workpieces prepared on the worktable. At the same time, the temperature that the film receives contributes to the activation and strengthening of the adhesive layer.

Thus, the vacuum pressing technology can easily cover with polyethylene film (PVC) the most complex and deep profiles of molded products (as well as parts of the facade interior). Thanks to this technology, we are able to produce continuous profile lines, and even complement products with rounded shapes. As a result, the surfaces of products become more wear-resistant, and the service life increases many times over.

There is also the possibility of 3D lamination of facades. PVC film, as soon as it is heated, becomes very plastic and takes the necessary shape. As soon as it cools down, the form taken before is preserved. On this type, equipment for laminating facades is based.

What are the presses?

- Vacuum presses, our company has developed

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

Differences in price and design:

Thermal vacuum presses are more common and have a low cost. They are easier to use.

Overpressure presses are a more complex and expensive design.

Both of these presses can be additionally equipped with a membrane in order to be able to press porous materials or veneer, and the membrane is practically not used for laminating with PVC film.

Pressure comparison between a vacuum press and an overpressure press:

Overpressure presses are capable of compressing 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 enough for most lamination manipulations. An exception can only be the coating 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, an overpressure press is 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 blanks are placed. There is also a heater used to heat the film and a vacuum system. It provides an equivalent pressure on the PVC film, applying atmospheric pressure or pumping excess pressure.

How does the process of laminating with PVC film using a vacuum press look like:

The process of laminating the furniture facade from MDF with PVC film

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

In the figure, the desktop, on which the workpieces are placed, which in turn lie on the lining

2. A PVC film is fixed over the entire surface of the table (special clamps 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's 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, the moving element is a table, in some cases, 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 press model, the film does not touch the heater. Another name for this type of heater is infrared.
Ideally, uniform heating of the film to the desired temperature should be obtained (each PVC film has its own heating index). 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 film heating stage is completed, a new one begins - vacuuming. Or in another way - 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 desired temperature to the surface of the workpieces. At the same time, the heating temperature causes the adhesive base to become more active.

Workpieces in the process of vacuuming continue to be heated (reheating occurs)

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

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

A vacuum press is a piece of equipment that can be used to give various materials the desired 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. With the help of vacuum forming equipment, car dashboards, toys, packaging, mugs and other plastic products are made.

vacuum pressing

Vacuum pressing is a process in which curved glued furniture and interior elements are created and lined. Today, there are a huge number of installations with different capabilities. There are universal installations that are able to work with film or natural material.

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

Vacuum pressing may differ:

• according to the design of the heating elements;
• the method of moving the heating elements;
• type of fastening of a removable membrane;
• type of module for heating;
• applied vacuum pumps;

The thermal vacuum press is one of the most frequently encountered units in vacuum pressing. It copes with the cladding of the facade of furniture with PVR film, doors with veneer material, as well as the manufacture of curved glued products that have dimensions not exceeding the dimensions of the press.

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

Vacuum forming plastic

Vacuum molding 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 heat. Vacuum forming, as a rule, is a mass production of products. At the same time, there are small installations with which you can create a small souvenir or other similar products.

Vacuum molding 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, bathtubs, covers and other elements.
• when creating car elements: moldings, plastic panel parts, toolbox boxes and many other products;
• when creating household products: aquarium covers, garbage containers;
• when creating interior elements: figurines, furniture elements;
• while creating constituent parts medical installations: consoles, containers, baths;

Objects made by vacuum molding are present in large quantities in the life of every person. This technique is one of the most ambitious to date and is used in almost all industries.

Membrane vacuum press

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

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 determine how well the operation will be performed. As a rule, bag manufacturers make sure that the products are durable, elastic, and transparent.

It is important to use professional bags that can be used repeatedly. They will not tear under the influence of temperature and in a vacuum. With their help, you can perform various pressing work, because they are not afraid of heavy loads.

Vacuum press for MDF facades

A thermal vacuum press is the machine that works best for an MDF facade. In our country, there are a large number of installations of this type, capable of performing tasks of varying complexity. The choice of a vacuum press for an MDF facade is always a difficult process, since it is easy to get confused in the characteristics and other key indicators.

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

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

Equally important is the choice of thermal module. The best option there will be a lifting temomodul, which is mounted on hinges. This design is effective because it saves working space in production. At the same time, laying parts and stretching the foam becomes much more difficult.

Today, many enterprises are switching to membrane-vacuum plants, 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 match the characteristics of the speed, 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 vacuuming operations 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 installation and the materials used for lubrication;
• parameters of the created pressure and speed;
• cleanliness of the operation;
• dimensions;
• noise and vibration;

Rotary vane vacuum pump

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

To date, there are many different modifications of models of this type. At the same time, the main distinctive features vane vacuum pumps of similar performance is the fact of using or not using vacuum oil.

Oil vacuum units have a higher productivity, since they have practically no gaps between the main moving structural elements. They are sealed with vacuum oil. At the same time, vacuum oil is able to evaporate during operation, thereby polluting the pumped air. This fact makes "dry" pumps more preferable for work in a vacuum press.

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

Liquid ring vacuum pump for press

The water ring vacuum pump is quite well suited for performing vacuum in pressing equipment. It, despite the fact that it has a relatively low performance, is a universal means of pumping gases of various types.

A liquid ring vacuum pump uses water as the working fluid. It contributes to the fact that the installation does not overheat during operation and is lubricated independently. At the same time, contaminated gases, in contact with water at high speed and with high pressure are starting to clear up. This makes it an excellent choice for a vacuum press where outgassing is present.
