Jet Coolers and Copper Chills for targeted thermal management in die casting dies
Overview
What Are Cooling Systems?
Jet Coolers are precision-machined assemblies that connect the cooling water supply to the internal bore of a jet cool core pin, directing high-pressure fluid directly to the extreme tip of the pin. Copper Chills are inserts manufactured from high-conductivity copper alloy and embedded in the die to provide passive thermal sink cooling in thick sections or isolated hot spots that drilled water circuits cannot reach.
Effective thermal management is one of the most significant factors controlling casting quality, cycle time, and die longevity. Where conventional drilled cooling circuits cannot reach, Vyankatesh Engineering's cooling products — Jet Coolers and Copper Chills — provide targeted, high-efficiency heat extraction exactly where it is needed.
Why Choose Vyankatesh
Benefits
Cooling delivered exactly where heat accumulates — at the pin tip or in thick casting sections — rather than relying on general die body temperature.
Jet coolers reduce shrinkage porosity in core zones. Copper chills promote directional solidification in thick sections to eliminate internal voids.
Effective hot-spot cooling enables faster solidification and shorter cooling dwell — reducing cycle time without compromising casting quality.
Reducing peak die temperatures at hot spots significantly extends die life by reducing the severity of thermal fatigue cycling.
How We Make Them
