Principle of heat press

Adding positive pressure on the basis of negative pressure, together with special glue, for the processing of PVC series, its line shape and sticking force are incomparable with negative pressure equipment, because of its high pressure, low temperature and short film pressure time , It solves the deformation problem when negative pressure equipment processes workpieces (especially large-area workpieces), and greatly reduces the degree of deformation of workpieces. Using advanced electronic new product control, through adjustment, the processing procedures of table entry, table raising, heating, vacuum, film pressure, film stripping, and table lowering can be automatically completed. It is mainly powered by oil pressure and compressed air, so there must be sufficient air pressure and air volume. The frame is integrally processed with steel plates, and the overall structure is reasonable. The two workbenches can be recycled or used separately. The vacuum can be adjusted to low pressure first, then high pressure suction coating, and the film pressure can reach 0.4MPa. Through adjustment, the product can achieve the desired effect.

 Operating procedures

1. Turn on the power of the heat press, preheat the heat press, and check whether the gluing machine and the heat press work normally.
2. Start the gluing machine to prepare the high-viscosity glue in proportion and pour it into the glue tank of the gluing machine.
3. Prepare the product parts to be pasted and the corresponding veneer, and sweep the dust off the surface of the parts to be pasted with chicken feathers.
4. Pass the parts to be pasted through the rubber wheel of the gluing machine, so that the parts are evenly coated with glue (use glue for parts that are too large).
5. Then spread the veneer on the rubber surface of the parts and put it on the hot pressing plate of the hot press.
6. Set the parameters of the hot press (temperature, pressure, hot pressing time). After each layer is filled with pressed parts, press the press button with both hands to pressurize.
7. After the hot pressing time, the machine automatically releases the hot pressing layer and removes the pressed parts from the hot pressing machine.
8. Put the removed parts on the workbench, and overhaul the parts beside the parts.
9. Each component must be self-inspected, and after passing the self-inspection, it is placed on the pallet, marked and transferred to the next process.

 Process requirements

1. The veneer cladding needs to be tight and smooth. The splicing of the cladding of various materials should be tight, smooth and overlapping.
2. The veneer splicing needs to be diagonally correct, and the angle must be 45 degrees.
3. Damaged corners must be repaired with repair glue, and 502 glue is not allowed to be used for repair.
4. Note the grain direction and patchwork.


1. If the pressed part is not filled with the hot-pressed layer, it must be filled with plates of the same thickness, and suspended pressing is prohibited. There should not be too many or too few boards.
2. Before leaving get off work, remove the excess glue on the gluing machine and clean the rubber wheel shaft of the gluing machine.
3. Be careful not to let the rubber wheels pinch your hands when washing the gluer. The washing water is poured into the recycling unit.
