Abstract:
A method for injection molding parts, comprising the following steps:a) plasticizing a mixture of a plastic material and fillers or reinforcement materials in a reciprocating screw plasticizing and injection unit, by rotating a plasticizing and injection screw; b) expelling the plasticized mixture of plastic material and filler or reinforcement material by the axial movement of the plasticizing and injection screw, from the reciprocating screw plasticizing and injection unit, into a mixing element; c) homogenizing the mixture of plastic material and filler or reinforcement materials in the mixing element, by a mixer, which is disposed movably in the mixing element and which is driven by a mechanical drive; and d) expelling the homogenized mixture of plastic material and filler or reinforcement materials from the mixing element into an injection molding tool.
