Plywood hot press working principle

plywood hot press

Plywood hot press is a common woodworking machine equipment, mainly used for pressing multilayer boards or other materials together to form plywood.The working principle is to use the force of high temperature and high pressure, glue is applied to the surface of the wood board. And then multiple layers of wood are superimposed on top of each other, through the heat and pressure action of a hot press. So that the glue quickly solidifies at high temperature, thus forming a strong plywood.

The main components of plywood hot press include heating system, pressure system, control system and frame, etc. Among them, the heating system is the core part of the hot press, its role is to raise the temperature inside the machine to a certain degree, so that the glue can be cured quickly.Heating systems usually use electric heating or steam heating to transfer heat through the heating plate to the surface of the board to bring it to the desired temperature.

Pressure system is another important part of plywood hot press. Its role is through hydraulic or air pressure force, the multilayer wood pressing together, so that it forms a strong plywood. Pressure system is usually composed of hydraulic cylinder, oil pump, oil tank and pressure gauge. By controlling the oil pump work, adjust the pressure of the hydraulic cylinder, so as to achieve the pressing of the board.


The control system is the intelligent part of the plywood hot press. Its function is to control the heating system and pressure system through the electronic controller, so as to realize the automatic operation of the plywood hot press. The control system is for the most part composed of PLC controller, touch screen, electrical components and sensors. Through the control of each component, so the automatic control of plywood hot press is realized.
