Abstract: A method for injection molding of thermoplastic pole parts utilizes a mold to fix at least one vacuum interrupter and contact terminals during a molding process. At least one injection opening or gate for injection of thermoplastic material is formed into the mold. The mold is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and the injection openings or gates can be steered in such a way that they inject thermoplastic material simultaneously or with a defined time dependent injection pattern. This process alleviates the issue of a pressure gradient along the long axis of the molded pole part, shortens process times, and achieves a homogenous dissipation of material during the molding process.
