Plastic Profile Extrusion Lines

Plastic Profile Extrusion Lines is a kind of plastic machinery products. In addition to this, there are plastic pipe production lines and plastic sheet production lines. The plastic extrusion profile production line is mainly used for the production of plastic door and window profiles, plastic decorative panels, PVC foam profiles and other plastic products.
Forming state of coextruded material
The plastic profile extrusion process can be divided into two types: pre-coextrusion and post-coextrusion according to the molding state of the coextruded material. Pre-coextrusion means that two materials are composited in the process of not being fully formed; post-coexcitation means that one material has been completely formed and then composited with another material. The advantage of post coextrusion is that it can utilize waste materials and is economical.
By extrusion material
The extrusion process of plastic profile can be divided into organic coextrusion and inorganic coextrusion according to different extrusion materials. Organic coextrusion consists of co-extrusion of the same material (such as pre-coextrusion of fine material and mixed regrind) and co-extrusion of different materials (such as co-extrusion before PMMA and PVC) and post-coextrusion of soft and hard PVC; inorganic coextrusion can be divided into aluminum-plastic composite co-extrusion and steel-plastic composite co-extrusion.
The focus is on co-extrusion, co-extrusion of aluminum-plastic composite profiles, co-extrusion of steel-plastic composite profiles, and two-color coextrusion.
Compared with the traditional pre-coextrusion (hereinafter referred to as FCE) technology, the post-coextrusion plastic profile extrusion process has the characteristics of simple process, flexible application, low scrap rate, easy recycling, and controllable bond strength. At present, this technology is mainly used to manufacture profiles for doors and windows with sealing strips.
The traditional pre-coextrusion plastic profile extrusion process technology is a one-shot molding technique. Molten materials having different rheological behaviors or different colors are extruded from the two or more extruders into the same molding die, and the melts flow in the respective flow paths in the molding die, and then merged and extruded at the die, and The set is vacuumed and cooled.
