| Casting Process | Advantages | Limitations |
| Gravity Casting |
Good surface finish; Good dimensional accuracy; High production rate; |
High mould cost; Suitable for high volume production; Suitable for casting of simple shapes; Suitable for low-melting-point metals;
|
| Die Casting |
Excellent Surface finish; Excellent dimensional accuracy; High production rate; Complex shapes can be cast; Little or no finishing cost;
|
Limitation on part size; High cost of die; Generally limited to cast ferrous metas;
|
| Sand Casting |
Almost any metal can be cast; No limit on size and shape; Low equipment cost; Economical for low-volume production |
Dimensional accuracy not so good; Finishing required; Low production rate; |
Quality
| Size inspection | check whether the shape and size of the casting meet the requirements |
| Visual inspection | check whether the casting has casting defects |
| Physical and chemical testing | check the chemical composition of the casting, metallographic structure, whether the mechanical properties meet the requirements |
| Pressure test | check the compactness of the casting, whether the casting leaks or leaks |
| Internal quality inspection | such as magnetic particle inspection, X-ray, Y-ray detection, ultrasonic detection |
