Injector
Precise injection
Our Gas Internal Pressure Technology (GIT) revolutionizes the injection molding process by injecting gas into the plastic mass after the injection phase. This innovative technique optimizes material distribution and enhances the overall quality of the final product.
The injectors are directly integrated into the injection mold. Depending on the size and geometry of the injection part, as well as the flow behavior of the melt, one or more injectors can be placed within the tool. The gas (nitrogen) is controlled via a regulation module and flows through holes in the mold to the injector and then into the molded part. The degassing or relaxation occurs through the same injector (only type GKR).
Cavity gasification is only possible when the injection pressure is higher than the counterpressure in the cavity. The gas pressure fully opens the injector, allowing for large volume flows to be achieved. The degassing occurs through star-shaped arranged surfaces (only type GKR) at the sealing cone of the piston. The gap is large enough to allow gas to flow but small enough to prevent the intrusion of plastic.
Maintenance of the mold injector can be easily and quickly performed via the mold separation plane.
