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.

Superior conformal cooling design
Engineered to allow the optimal thermal management, depending on the customer challenge.
- The channel configuration follows the external 3D shape of the runner, maintaining a uniform wall clearance.
- Channels positioned to maximize thermal performance, enhance longevity, and ensure thermal uniformity.
- The design features smooth, continuous transitions without sharp edges, optimizing flow properties for minimal pressure drop, high flow rates, and an excellent heat transfer coefficient.
Uniform Heat Distribution
Advanced thermal management
-
Up to 30% better fatigue resistance
Uniform surface temperatures lead to lower thermal gradient, which in turn results in lower induced thermal stresses and leads to improved thermal fatigue resistance, hence longer life span. -
Up to 25% reduced risk of die soldering
Lower working temperature reduces the softening effects and decreases the risk of diffusion. This leads to less erosion and less depositions which have a large influence on die soldering.
Cycle Time Reduction
Our customers have reported up to 20% shorter cycle times when replacing conventional Shot Block with iTherm® Shot Block.
-
Faster bisquit solidification
Lower working temperature and faster cooling results in faster solidification of runner and biscuit. Additionally lower temperature requires less time for spraying and blowing.
