Pvc sealing strip forming method
1. Use an open mill to mix the materials evenly, process them into sheets, and then extrude the sealing strips. This kind of production process has many procedures, slow production speed and low efficiency.
2. The mixed materials are pelletized by a single-screw extruder, and then the pellets are plasticized by the extruder, and the die is formed into a continuous strip product with a special shape in cross section. After cooling, the product is crimped to obtain the product.
3. The mixed powder is directly plasticized by the extruder and molded into a sealed product.
