Custom Nitriding Coating Die Casting Mold Parts & Core Pins
HPDC core pins feature small internal cooling channels that extend nearly to the tip, enabling high-pressure water and air circulation for effective heat dissipation. The precise positioning of these internal channels relative to the pin's external diameter is critical for maximizing component lifespan and cooling efficiency. Component longevity can be further enhanced through thermo-chemical treatments and specialized surface coatings.
Senlan utilizes precision equipment and machinery to manufacture the most critical HPDC core pins for aluminum high-pressure die casting molds. Our focus on continuous improvement in reliability and lifespan delivers significant productivity advances for our clients.

Core pins endure significant thermal stresses during casting processes. Traditional heat extraction limitations, particularly in small-diameter core pins, often lead to frequent breakage, metal adhesion, and erosion issues. Additionally, areas surrounding core pins can develop shrinkage porosity in manufactured components.
