Sprue Bush

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

Key features and benefits

Tool steel material

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

Reduced cycle time

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

No leakage

Utilizes a single inlet and outlet, effectively eliminating leakage points and simplifying the cooling circuit.

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.
