Abstract

A process for manufacturing plastic moldings while increasing the coefficient of viscosity of the raw material used to manufacture same and to a molding manufactured according to the process. To increase the loadability and the service life of moldings manufactured by injection molding, which are subject to dynamic loads during their use, the granular material used is tempered before the shaping processing in the injection molding process for a period of 10 hours to 30 hours at a temperature between 90 C and 150 C. Without resorting to higher-priced materials, highly loadable moldings can be manufactured by this process, which can be advantageously used by the manufacturer without a greater effort. A corresponding molding, such as a worm gear, manufactured according to the process from a granular material with an original solution viscosity between 180 mL/g and 190 mL/g, has a solution viscosity between 180 mL/g and 200 mL/g.
