Plastic Profiles Extrusion Line
Plastic extrusion profile production line is mainly used for the production of plastic doors and windows profiles, plastic decorative sheet, PVC foam profiles and other plastic products.
Plastic profile extrusion process according to the co-extruded material molding state can be divided into two types of co-extrusion and post-co-extrusion. Pre-co-extrusion refers to the two materials in the process of incomplete molding to achieve composite molding; after co-extrusion is a material has been fully formed, and then another material to achieve composite molding. The advantage of post-co-extrusion is the ability to use waste, the economy is better.
