has a group of advanced extrusion spinning thermoplastic materials

摘要

a group of extrusion spinning molten thermoplastic synthetic material, in particular for the production of polypropylene filament.includes a chamber of melting and extrusion head.it is characterized in that the melting chamber (3) has a large area and a small length, the heating means (4).5) to melt the polymer and (2) are located in the interior of the chamber, in a same plane, and in that the heating means is a columnar body with metal (4).preferably made of steel, in which are embedded longtitudinales resistance (5).
