Comparison Of Different Molding Methods | MIM | PM | Precision Casting | Forging | Mechanical Machining |
Cost | Fair | Low | Fair | Fair | High |
Density | 94~99% | < 95% | 100% | 100% | 100% |
Productivity | High | High | Fair | Fair | Low |
Mechanical Property | Good | Fair | Good | Good | Good |
Surface Roughness | Fine (1um Ra) |
Coarse | Fair ( 5um Ra) |
Fine | Fine |
Complexity of Shape | High | Low | Fair | Low | High |
Dimension Accuracy | Fair ( 0.4%) |
High | Fair | Fair | High |
Other Disadvantage | The max dimension must <110mm or 4.5inch | Less surface-treated ability | surface-treated ability Cost higher toproduce partswith small holes, thin sheet, sharp edges | Majorly produce2D parts | Difficult to work on hardmaterials |
