iTherm® Sprue Bushing
iTherm® Sprue Bushing is produced using tool steel forged or rolled blocks and HTS proprietary additive manufacturing technology.
It is a single body component with equal mechanical properties as tool steel monoblock.
Cooling channels can be freely designed according to the cooling/heating requirements of the product, not by the limitations of using the conventional drilling method.
It is highly customizable to specific customer requirements.
HTS DIFFERENCE
Advantages over conventional sprue
More freedom designing cooling channels
In comparison with conventionally made sprue bushing, iTherm® Sprue bushing gives you extra flexibility to bring cooling channels near the critical zones of the sprue.
Faster sprue bushing cooling rate
In comparison with conventionally made sprue bushing, using iTherm® Sprue bushing, the heat is distributed much more evenly over the surface, so the sprue is cooling down more evenly and quicker.
Cycle time reduction
Combining the advantages of iTherm® Sprue bushing you can significantly shorten cycle time. Our customers have reported up to 25% shorter cycle times on dies limited by sprue cooling when replacing conventional sprue with iTherm® sprue.
