Product Description

Screw is the key component in plasticized parts, which is in direct contact with plastics. Plastics through the effective length of the screw groove has a long thermal history. It has to undergo the transformation of three states (glass, viscoelastic and viscous flow). The length, geometric shape and geometric parameters of each functional section of the screw will directly affect the conveying efficiency and plasticized quality of plastics, and will ultimately affect the injection molding cycle and products. Quality.

Injection screw can be divided into general screw and special screw according to its adaptability to plastics. General screw, also known as conventional screw, can process most thermoplastic plastics with low and medium viscosity. Crystalline and non-crystalline civil plastics and engineering plastics are the most basic forms of screw. Correspondingly, there are special screw, which is used to process Plastics difficult to process with ordinary screw, such as thermosetting plastics, polyvinyl chloride, PMMA screw with high viscosity. According to the screw structure and its geometrical shape, it can be divided into conventional screw and new screw. Conventional screw, also known as three-stage screw, is the basic form of screw. There are many new types of screw, such as separate screw, split screw, corrugated screw, transverse screw, non-metering screw, two-stage chlorine removal screw, strong mixing screw and so on.
