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.

Tapout cone is used in reverberatory furnace in aluminum melting It is a soft vacuum formed ceramic fiber part It is used to cover & plug tap hole plugs used in furnaces for melting for Aluminum, magnesium & zinc alloys

Operator can visually check the flow of cooling medium in the core pin cooling process Operator can check continuity of flow in each line Ball inside the unit moves displaying fluid movement and if any one or more ball stops moving, it indicates malfunction Designed & manufactured for number of lines which needs to be monitored
