PU plastic custom extrusion profile

Extrusion molding, also known as extrusion molding or extrusion molding, mainly refers to a molding method in which heated and melted polymer materials are forcibly formed into continuous profiles with constant cross-section through the die under the promotion of pressure with the help of the extrusion of screw or plunger. Extrusion process mainly includes feeding, melting and plasticizing, extrusion, shaping and cooling. Extrusion molding is an efficient, continuous, low-cost and wide-ranging molding processing method. It is an early technology in polymer material processing. After more than 100 years of development, extrusion molding is a molding processing method with the most production varieties, the most changes, high productivity, strong adaptability
