CNC Plywood Hot Press for Plywood Production Machine
Hot press production process
The slab is loaded into a hot press, and the adhesive is fully cured by heating to make a production process of plywood with high strength. Hot pressing is the most critical procedure in plywood production, which directly affects the strength and yield of plywood.
During the hot-pressing process, hot-pressing pressure, hot-pressing temperature, and hot-pressing cycle are key process parameters that affect product quality, and should be controlled from the following aspects:
1. Determination of hot-pressing temperature The hot-pressing temperature is mainly determined according to the type of adhesive, focusing on the temperature selection of urea-formaldehyde glue and phenolic resin, and the moisture content of the veneer should also be considered
2. Selection of hot pressing pressure If the hot pressing pressure is too high, the compression ratio of the slab will be too high, and the cost of raw materials will increase; if the pressure is too small, the strength of the plywood will decrease, which will affect the product quality. The pressure should be controlled within an appropriate range according to the process requirements, and the gauge pressure of the hot press should be calculated according to the unit pressure during operation
3. Determination of the hot-pressing cycle The hot-pressing cycle is mainly determined according to factors such as the thickness of the slab, the moisture content of the veneer, the type of glue, the hot-pressing temperature and the hot-pressing pressure. Experience, bulletin inspection of product quality to find out the heat press cycle parameters.
