Brief Analysis of Classification and Characteristics of Plastic Profile Production Lines

The plastic extrusion profile production line 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.

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 and is economical.

The extrusion process of plastic profile can be divided into organic coextrusion and inorganic coextrusion according to different extrusion materials. Organic coextrusion includes co-extrusion of the same material (such as pre-coextrusion of fine materials and mixed materials) and co-extrusion before different materials (such as co-extrusion of 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.

In this focus, the co-extrusion extrusion, aluminum-plastic composite profile co-extrusion, steel-plastic composite profile co-extrusion and two-color co-extrusion technology.

Compared with the traditional pre-coextrusion (hereinafter referred to as FCE) technology, the post-coextrusion plastic profile extrusion process has obvious features such as 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. More than two extruders are used to extrude molten materials with different rheological behaviors or different colors to the same forming die. These melts are characterized by the automatic production line of molded aluminum (steel) plastic composite pipe. The machine is mainly made of PVC, PP and PE. Production of small-diameter single-wall corrugated pipes for raw materials.

Corrugated tube products with smooth inside and outside and uniform corrugation are formed through the corresponding mold at one time.

Wire and cable threading pipe, washing clothes drain pipe, vacuum cleaner pipe, ventilation pipe, etc.

Carefully developed bellows for small-diameter automotive wires such as 4-6.7mm to fill domestic vacancies
