Core pins are under high thermal stresses during the casting process and, because of the traditional limits for heat extraction, especially in the core pins of small diameter, they undergo frequent breakings and adhesion to the casting metal and erosion problems as well.

On the other hand, the surrounding areas of the core pins can be problematic points where there could be shrinkage porosity in the manufactured part. The development of the last decade has enabled minimising these unwanted situations. The cooling of the critical areas by means of the HPPC (High-Pressure Pulsating water Cooling) offers the die caster the advantage of controlling, accurately, the cooling of the hot areas around the core pins and, in this way, of minimising the shrinkage porosity problems and/or the adhesion and erosion on the core pins.
