Solution to uneven pressure of plywood hot press machine
The uneven pressure of the plywood hot press machine is manifested by significant differences in density and thickness of various parts of the pressed board, which may cause quality problems such as warping and delamination of the board, affect the product qualification rate, and increase production costs and rework rates.
solution
Adjust machine parameters: recalibrate and debug parameters such as pressure, temperature, and pressing time.
Replace parts: If the hot pressing plate is deformed or the hydraulic cylinder seal is aging, it should be replaced in a timely manner.
Cleaning machine: Clean the oil stains, debris, and hydraulic system oil blockages on the surface of the hot press plate.
implementation steps
Prepare tools and materials such as wrenches, micrometers, hydraulic oil, seals, etc. First, stop the machine and turn off the power. Use a dial gauge to check the flatness of the hot press plate. If there is a large deviation, it needs to be calibrated or replaced; Check the hydraulic cylinder seals and replace them with new ones if they are worn or aged; Clean the surface and oil circuit of the hot pressing plate, use professional cleaning agents to remove oil stains, and unclog blocked areas; Finally, reset the pressure, temperature, and time parameters and start the machine for trial operation.
desired result
After implementing the above measures, the pressure distribution of the hot press will be more uniform, and the quality of the pressed plywood will be significantly improved. Defects such as warping and delamination will be reduced, the product qualification rate will be improved, and the processing efficiency and economic benefits will be improved accordingly.
