Gravity Die Casting
1. Features of Gravity Die Casting
Compared with Sand Casting and other methods the dimensional accuracy is excellent, products can be produced with less finishing allowance, a smoother casting surface, and fine grain size with less pin holes due to the faster cooling rate, which achieves excellent mechanical properties at lower costs.
2. Thin Wall Thickness Compatibility
Mold costs are low. Hardness, which is difficult to achieve with die casting, can be guaranteed through a heat treatment process. In addition, the biggest feature of gravity casting is that it allows the use of shell cores, making it possible to mold complex internal shapes.
3.Response results
Achieves uniform quality from the vicinity of the casting surface to the center. Thick-wall compatibility, which overturns the conventional wisdom that the feature density becomes coarser toward the center of thick-walled parts. This increases the degree of freedom in product design and enables the creation of products with extremely small differences in strength between parts.
