1. Preheating of plastic sheet production equipment: This is before starting the mold heating action.

2. Clamping: reasonably adjusting the opening and closing stroke can improve the product demoulding and feeding effect.

3. Preheating of PVC plastic sheet production line: steam can enter the fixed moving mold to preheat the mold so that the mold design can be preheated and the condensed water and cold air during the retention period can be discharged.Function: improve the working temperature of molds in China and strengthen the apparent fusion degree of cultural products.

4. Penetrating material heating: improve the core and internal fusion of biological products. Through different heating consumption, waste and steam are serious.

5. Double-sided heating: further enhance the heating effect and improve the surface quality of products.

6.Temperature return(thermal insulation):all valves are closed,and the waste heat of the mold is fully developed and utilized to make the products have different thermal insulation and heating.It is conducive to the surface fusibility of product structure and can better save resources and energy(steam).

7. Vacuum cooling: the vacuum valve is opened and the vacuum pump is vacuum. The molds and products are completely emptied in waste heat and water, and some foaming agents avoid product expansion. Negative pressure is formed in the mold, which is conducive to the demoulding of products.
