Principle of hot press---Fujian hot press

Positive pressure is added on the basis of negative pressure, with special glue. For the processing of PVC series, its linearity and sticking force are incomparable to negative pressure equipment because of its high pressure, low temperature and short film pressure time. , It solves the problem of deformation of workpieces (especially large-area workpieces) when processed by negative pressure equipment, and greatly reduces the degree of deformation of workpieces. The advanced electronic new product control is adopted, and the processing procedures of entering, raising, heating, vacuum, film pressure, removing film, and lowering the stage can be automatically completed through adjustment. It is mainly powered by oil pressure and compressed air, so it must have sufficient air pressure and air volume. The frame is integrally processed by steel plate, 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, the membrane pressure can reach 0.4MPa, and the product can achieve the desired effect through adjustment. ---Fujian hot press

Operating procedures

1. Turn on the power of the heat press, preheat the heat press, and check whether the glue machine and heat press work normally.

2. Start the gluing machine to mix the high-viscosity glue in proportion and pour it into the glue tank of the gluing machine.

3. Prepare the product parts to be heated and the corresponding veneer, and wipe the surface dust of the parts to be pasted with chicken feathers.

4. Pass the parts to be pasted through the rubber wheel of the gluer, so that the parts are evenly coated with glue (the parts are too large, use glue).

5. Then lay the veneer flat on the glue surface of the part, and put it on the hot plate of the hot press.

6. Set the parameters of the hot press (temperature, pressure, hot pressing time) after each layer is filled with pressing parts, press the pressing button with both hands to press. ---Fujian hot press

7. After the hot pressing time, the machine automatically releases the hot pressing layer and removes the pressed parts from the hot press.

8. Put the removed parts on the workbench, and inspect and repair the parts beside the parts.

9. Each component must be self-inspected, and after passing the self-inspection, it is placed on the card board, and the label is transferred to the next process.

Process requirements

1. The veneer cladding should be tight and smooth. The splicing of the cladding of various materials should be tight, smooth and overlapping. ---Fujian hot press

2. The veneer splicing must be diagonally opposite, and the splicing angle must be 45 degrees.

3. Repairing with damaged corners must be repaired with repairing glue, and 502 glue is not allowed to repair. ---Fujian hot press

4. Pay attention to the direction of the wood grain and the patchwork.


1. The pressing piece is not filled with the hot pressing layer, so it must be filled with a plate of the same thickness, and hanging in the air is prohibited. The plates should not be too many or too few.

2. Before leaving get off work, remove the excess glue from the gluer and clean the rubber wheel shaft of the gluer.

3. When washing the glue machine, be careful not to let the rubber wheel pinch your hands and pay attention to safety. Pour the washing machine water into the recovery device.

Quality requirements

There should be no degumming, penetration, wrinkles, overlap, etc. ---Fujian hot press

The amount and temperature of glue used in the same batch or set of products should be the same.

Work site requirements

The site is neat and clean, and the products are neatly stacked. Put the side skins in the trash can. The glue is placed on the tray.
