COOLING JIG FOR EXTRUDING PCTFE STRINGS AND METHOD FOR EXTRUDING PCTFE STRINGS

摘要

The invention relates to a method for making PCTFE strings, that comprises extruding PCTFE with an extruder connected to an assembly comprising a die (3) and a metallic cooling jig (2), characterised in that a material (6) is provided between the inner metallic wall of the cooling jig and the PCTFE such that the friction between the PCTFE and this material is lower than the friction between the PCTFE and the metal of the cooling jig.
