Bolt shut-off

Efficiently keeping sprue openings clear in hot runner systems is critical for consistent and uninterrupted production. By using a melt filter in our shut-off nozzles, the intrusion of foreign particles into the cavity is prevented. This reduces the risk of blockages and increases process reliability.
Our filtration technology helps extend the lifespan of hot runner systems, reduces maintenance intervals, and overall enhances production efficiency.

The integration of a mixer directly into the shut-off nozzle represents a significant advancement in improving melt quality. The mixer ensures uniform homogenization of the melt in terms of both color and temperature.
This consistent mixing significantly reduces color deviations and temperature variations, minimizing scrap rates and leading to a substantial improvement in the quality of injection-molded parts. The mixer ensures an even distribution of color pigments and a homogeneous melt temperature, contributing to greater precision and consistency of the final products.
The installation of the mixer into the shut-off nozzle is efficient and precise, optimizing the entire injection molding process. This integration not only enhances the quality of the produced parts but also improves overall production efficiency and cost-effectiveness.

The gas injection at the machine nozzle is conducted through the core of the sprue, ensuring precise and controlled gas input. For use in the Gas Injection Technology (GIT) process, the conventional nozzle component is replaced by a specialized gas module. This gas module is designed to provide a gas-tight seal in the gas supply area, ensuring reliable and safe gas injection.
The robust, maintenance-free gas module offers additional safety with an integrated shut-off mechanism to the screw chamber, preventing unintended gas leakage and enabling stable and controlled process management. This technical design enhances process reliability and improves the quality of manufactured parts.
