How it works

1. The press is opened and the membrane is pulled onto the upper pressure plate by a vacuum for heating.
2. The pallet, containing the workpiece and covered by the coating, moves into the press.
3. The press closes and hot compressed air separates the membrane from the heating plate. The coating, which is stretched between the positioning frame and the upper spacer frame, is pulled onto the membrane by a vacuum; it continues to be heated by hot air from the upper chamber. A vacuum is produced in the lower chamber, and a simultaneous positive pressure in the upper; the membrane presses the coating material onto the surface of the workpiece, and the heat passing directly through the membrane ensures that the adhesive is activated or cross-linked. The temperature can reach 160 °C and the pressure a maximum of 8 bar.
4. After the pressing process, the membrane is separated from the coating by cold air and pulled back onto the upper plate by a vacuum, where it is heated up again. The press opens and the ready-coated workpiece comes out.
