The first plastic molding composition -Crystallite melting point T m according to ISO 11357 above 170 ° C, A crystallization temperature T k according to ISO 11357 which is up to 70 K less than T m , and At least 20 J / g of melt enthalpy ΔH according to ISO 11357, a) extruding a plastic profile made of a first plastic molding composition which forms the outermost layer and consists of at least 50% by weight of a semicrystalline thermoplastic material, b) in the calibrator, insert the second plastic molding composition into the newly extruded profile, c) by calibrating, draining and cooling newly formed rods, The method of manufacturing rods enables the production of rods, in particular circular rods, with high dimensional accuracy in terms of diameter and straightness. The rod is particularly suitable as a semifinished product for producing finished parts by machining. |
