Method for producing an injection-molded product, corresponding injection-molded product, and use of especially prepared sunflower hull fibers as an additive

Abstract

A method for producing an injection-molded product is provided, where sunflower hulls are processed into sunflower hull fibers at a maximum temperature TPFmax of less than 200° C. Then an injection-moldable composite material is produced by mixing the sunflower hull fibers with a plastic material at a maximum temperature TPCmax ofless than 200° C. Next the produced injection-moldable composite material is automatically injection-molded into an injection-molding tool such that a molded composite material is produced. The composite material introduced into the injection-molding tool has a temperature TIM of more than 200° C. in at least one section of the injection-molding tool. Then the molded composite material is removed such that the injection-molded product is produced. A corresponding injection-molded product and the use of especially prepared sunflower hull fibers as an additive are also provided.
