| Injection molding |  |
 |
| Injection molding: injection molding machine will feed into the injection molding process similar to injection molding.The shape and structure of the parts forming the mold. | ||

|
| Debonding process |  |
 |
| Debonding: the use of physical or chemical process for removing parts of the binder components from the mixture of metal powder and a binder into a simple metal parts, the volume shrinkage, shape and structure unchanged. | ||
| |
|
|
| Sintering process |  |
 |
| Sintering: This process is the densification of the part, further contraction volume, shape and structure unchanged, when the relative density of ≥ 95%. | ||
