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

Characteristics: Peripheral to evacuate airgases from mold cavity and shot sleeve during a die casting process Helps to minimize air inclusionsgas porosities in the castings Better vacuum translates into optimum quality Reliable process monitoring reduces the rejection rate Integrates to any die casting machine Low maintenance Features: Designed with twin stage vacuum process by which air is evacuated in two stages: Stage 1 in shot sleeve and stage 2 in mold cavities Inbuilt vacuum pump and vacuum tank Monitoring of vacuum with graphical displays of stages Turnkey solution to support die casting process nature and cycles Custom built filters to secure the system User friendly operations with simplified touch screen setting Fully covered design to ensure user safety and withstand die casting process conditions Self detection of process abnormalities and stop function with alarmlight indications System is inbuilt with trouble shooting steps

Characteristics: peripheral to cool core pin during the die casting process integrates to any die casting machine injects water and air cyclically at high pressure into core pins of die casting mold technology at affordable price low maintenance uses shop floor air and soft water unit with integrated automatic water softener (optional) prevents clogging of core pins & jet coolers. Features: operative simply by connecting to the power source, start signal from the die casting machine, with water and air sources. powered by fully automated plc based control system hmi lets easy setup of the cooling cycle operation is by touch panel with alarm indications and trouble shooting high pressure cooling pump is inbuilt plug and play unit easy to install and setup meets challenges of servicing and maintenance cools 20 core pins with 2 cooling system and memorize cooling patterns for 16 parts

Core pin or hole forming pins are subjected to high thermal stresses during the die casting process. It comes in contact with molten alloy till it solidifies.
