Apparatus and a method for the extrusion of moulding from a cross-linkable polymer material |
摘要 |
The present invention relates to apparatus for extruding mouldings from cross-linkable polymer material. The apparatus includes a first part to which the polymer material is delivered from a material container, and a second part which forms a moulding tool for moulding and cross-linking said article. The first part of the apparatus includes a feed zone (2) that has an inlet (8), a generally tubular outlet (7) and a rotatable feed screw (10) that functions to compress and feed the polymer material in a unmelted or solid state from said inlet (8) to said outlet (7), wherein the length of the feed screw (10) does not exceed the length of the feed zone (2).
