High-Precision Die Casting Molds for Automotive Heat Sinks | Geqin Auto

Our automotive heat sink die casting molds are engineered to produce high-performance thermal management components with optimized fin geometries. The molds feature precision-machined cavities that create intricate cooling fin arrays with wall thicknesses down to 0.8mm. We utilize premium thermal-resistant steel grades for core components to maintain dimensional stability under repeated thermal cycling. The mold designs incorporate advanced ejection systems that prevent deformation of delicate fin structures during part removal. Our proprietary venting solutions eliminate gas entrapment in dense fin arrays, ensuring complete fill and superior thermal conductivity. The molds produce heat sinks with base flatness within 0.1mm/m for optimal contact with heat-generating components. We offer custom solutions for various aluminum alloys including A380 and ADC12, with cycle times optimized for production efficiency. The molds are designed for easy maintenance with modular components that allow quick replacement of high-wear elements. Our technical team can develop conformal cooling channel designs for applications requiring precise temperature control.
