it’s a processing method. refers to the material through the role of the extruder barrel and the screw, to be forward by screw while heating plastified, continuous through the nose and made a variety of cross-section products or semi-finished products .
in the chemical fiber industry is also useful in the extruder to the spinneret feed for melt spinning. extrusion is applied to the processing of thermoplastics and rubber. it can be used for batching, granulation and compound filtration. it can continuously produce, and manufacture all kinds of continuous products such as pipe, profile, sheet, film, wire and cable, rubber tire tread, inner tube tire, seal, etc.with high production efficiency. in the production of synthetic resin, the extruder can be used as a reactor to continuously complete the polymerization and molding process.
