Parameter description of plywood hot press machine

The parameter settings of plywood hot press directly affect product quality and production efficiency. The following are key parameter explanations:

Hot pressing temperature: usually set between 100 ℃ and 150 ℃, the specific temperature needs to be adjusted according to the type of adhesive and the thickness of the board. High temperature can accelerate the curing of adhesives, but it is necessary to avoid carbonization of the board caused by excessive temperature.

Hot pressing pressure: The pressure range is generally 1.0-3.5MPa, which is adjusted according to the density and number of layers of the board. Appropriate pressure can ensure uniform penetration of the adhesive layer and enhance the bonding strength of the board.

Hot pressing time: Depending on the thickness of the board and the characteristics of the adhesive, the time should be controlled between 1-5 minutes. If the time is too short, the adhesive layer may not cure completely, and if it is too long, it may affect the flatness of the board.

Closing speed: The closing speed of the hot press plate should be stable to avoid excessive movement or internal stress of the plate.

Reasonably setting the above parameters can effectively improve the mechanical properties and surface quality of plywood, reduce the defect rate, and is the key to ensuring production efficiency.
