Plastic extrusion profile production line is a kind of plastic machinery products. 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 can be divided into two types: pre co-extrusion and post-co-extrusion according to the co-extruded material molding state.
Pre co-extrusion refers to the two materials in the process of incomplete molding to achieve composite molding; post co-extrusion is a material has been fully formed, and then compound with another material to achieve composite molding. The advantage of post-co-extrusion is the ability to use waste material and save cost.
Plastic profile extrusion process can be divided into two types: organic co-extrusion and inorganic co-extrusion according to the different extrusion materials. Organic co-extrusion including co - extrusion with the same material and co - extrusion of different materials and soft - hard PVC after co - extrusion; Inorganic co-extrusion can be divided into aluminum-plastic composite co-extrusion and steel-plastic composite co-extrusion.
Compared with the traditional pre-co-extrusion technology, the extrusion process has the advantages of simple process, flexible application, low scrap rate, easy recovery and controllable bond strength. At present the technology is mainly used in the manufacture of doors and windows with a seal with profiles.
The traditional co-extruded plastic profile extrusion technology is a molding technology. Extruded from two or more extruders with the same molding die with different rheological behavior or different colors of molten material, the melt flows in the mold, and then extrude in the die at the convergence, vacuum, cooling and forming.
