Cooling of small diameter core pin was a major challenge for die caster. The developments in the last decade have made it possible now.
Advantages of Core Pin Cooling : During high pressure die casting of Aluminium alloys, generally there are three defects that are confronted by die casters on or around core pins:
- Soldering
- Shrinkage porosity around core pins
- Wash out
Cooling of core pins results in minimization of the defects. This process also improves the life of a core pin used in casting process. Here are some advantages of core pin cooling technology:
- Reduced die maintenance
- Decreased downtime of casting machines
- Increased life of die components, such as core pins
- Improved casting surface quality and dimension
- Reduced cost of tool for post processing
- Reduced use of lubricant
- Distortion control
