The key point in the laminating process is the pressure control. The greater the pressure, the better the product quality. The specific requirements are: the pressure rise shall be stable, the pressure control accuracy shall be high, the constant pressure time shall be accurately controlled, and the pressure of the product in all directions shall be uniform. In order to meet the requirements of laminating process and product production, the main design of equipment should include four parts: loading and unloading system, heating system, pressure system and protection system.
