Features of Precision Casting
- One step shaping casting of parts of complicated shape.
- To decrease machining, and reduce the cost.
- The material is easy to select, and available for small quantity production.
- The surface roughness is 63~125 R.M.S
- The minimum wall thickness of the casting is 0.8mm approximately.
- The casting weight: 0.005kg~80kg, and the size can be less then φ700mm.
