Sprue Bush

Custom Sprue Bush

Custom-designed conformally cooled solution for specific sprue configurations in cold runner systems.

Key features and benefits

Cooling channels – Engineered for optimal thermal performance and life span ratio.

Tool steel material Made from premium, industry-approved tool steel grades produced in the EU.

No leakage – Utilizes a single inlet and outlet, effectively eliminating leakage points and simplifying the cooling circuit.

More uniform heat distribution – Conformally cooled components enable more even heat distribution over the working surface, resulting in more uniform and rapid cooling.

Cycle time reduction – Combining the advantages of iTherm® Gate Insert with bushing, you can significantly shorten cycle time.

Lifespan extension – Shorter spraying time and consequently reduced thermal loads and thermally induced stress increase the number of shots before the crack initiation and propagation.
