Abstract

The invention relates to a process for the production of moldings composed of a polyoxymethylene polymer via blow molding, in which the polyoxymethylene polymer is extruded to give tubing, using an extruder with a grooved feed section, where the feed section is heated to a temperature in the range from 100 to 230° C., and the extruded tubing composed of the polyoxymethylene polymer is introduced into a blow mold, and a molding composed of the extruded tubing is produced in the blow mold.
