Changshu smoothly da plastic products factory talk about high molecular weight polyethylene extrusion molding method

Ultra-high molecular weight polyethylene (UHMWPE is a kind of linear structure has excellent comprehensive performance of thermoplastic engineering plastics, it has other plastic incomparable abrasion resistance, impact resistance, corrosion resistance, good low temperature resistance, self-lubrication and other comprehensive performance, is called & lsquo; It's surprising plastic & rsquo; , changshu below smooth plastic products factory is said high molecular weight polyethylene extrusion molding method.

extrusion molding equipment mainly include the plunger extruder, single screw extruder and twin screw extruder with synthetic twin screw extruder is preferred.

　　a. Plunger extrusion: plunger extrusion can be regarded as a pressing - Sintering process. This method of plasticizing time is long, low production efficiency, and the width of the products is limited.

　　b. Single-screw extruder: currently, single screw extruder molding of UHMWPE processing only 2%, but from the economical and practical single screw extrusion technology is the most valuable

c. Twin screw extruder, twin screw extruder to overcome UHMWPE powder in the screw slippage problem, greatly improve the ability of incoming material. Synthetic twin-screw extruder materials by the shearing action of small, also make the material in the process of extrusion to minimize heat degradation.
