Comparison of Casting Processes
| Casting Process | Advantages | Limitations |
| Die Casting | Excellent dimensioanl accuracy and surface finish; High production rate; | Die cost is high; Part size limited; Usually limited to nonferrous metals Long lead time; |
| Investment Casting | Intricate shapes; Excellent surface finish and accuracy; Almost any metal cast; | Part size limited; Expensive patterns, molds and labor; |
| Gravity Casting | Good surface finish and dimensional accuracy; low porosity; High production rate; | High mold cost; Limited shape and intricacy; Not suitable for high-melting-point metals; |
| Sand Casting | Almost any metal cast; No limit to size, shape or weight; Low tooling cost; | Some finishing required; Somewhat coarse dinish; Wide tolerances |
