Abstract
In a method for making long fiber-reinforced molded plastic parts, a continuous stand-reinforced melt is injected into a mold, after the latter has been closed, causing the mold to open until a predefined compression gap has been reached. The injection of long fiber-reinforced melt into the mold is continued and the mold is closed again. After permitting the long fiber-reinforced melt to cool down, the mold is opened and the end product removed. In this way, fibers can be introduced in a comparatively gentle manner into the mold and distributed therein, and fiber breakage and formation of surface marks are largely prevented.
