What is the processing technology of plastic door panels?

1. Process flow of plastic door panels: blanking → milling → grinding → glue spraying → secondary grinding → film covering → trimming and cleaning.

2. Sanding and secondary grinding operations In the manufacturing process of plastic door panels, there are advantages and disadvantages to stick a fire-proof board on the back of the base material sanded board → cutting with a chainsaw → milling → sticking a fire-proof board on the surface → bending and forming → edge sealing to complete the edge sealing tape.

Technically, there are two kinds of edge sealing: manual edge sealing and machine edge sealing. Machine edge sealing adopts automatic welding wheel pressure welding, and glue must be used to achieve no glue seam, no ripple, no glue opening, and good vision and feel.
