Sprue Bush

Sprue Bush

Standardized conformally cooled sprue bush with configurable dimensional features for fast adaptation to cavity-side configurations.

Key features and benefits                                                       

Conformally cooled – Engineered for optimal thermal performance and lifetime 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.

Reduced cycle time – Improved heat extraction at the alloy entry point accelerates solidification and time to die closure.

Extended lifetime – Reduced thermal fatigue and soldering extend the operational lifespan of the sprue bush.

Better Melt Control – Stable sprue temperatures minimize turbulence, gas entrapment, and surface defects.
