Our specialized gravity aluminum die casting process allows for the creation of custom castings to meet your specific requirements. Whether you require complex geometries, unique shapes, or intricate details, our team of skilled engineers and designers is dedicated to bringing your vision to life.
Gravity die casting (GLD) relies on the natural weight of the molten metal to fill the mold, fundamentally different from high-pressure die casting (HPDC), which relies on external pressure. In the automotive aluminum casting industry, these processes are primarily categorized as follows:
Metal mold gravity casting (Permanent Mold)
Sand core composite gravity casting (Semi-Permanent Mold)
