Metal Manufacturing Processes
| The Advantages of the Powder Metal Process | Powder Metal Parts |

	Advantages	Disadvantages
Screw  Machine	tighter tolerances wrought density little or no tooling more precision no secondary machining	higher part cost residual stress high volume of scrap material
MIM	complex geometry tighter tolerances 3-D configuration	longer lead time higher part cost only very small parts higher material cost no aluminum no bronze
Investment  Casting	lower tooling cost complex geometry 3-D configuration wrought density	longer lead time higher part cost longer cycle time
Forging	low cost higher strength	requires secondary machining
Stamping	lower piece price	must be thin ragged edges only large diameter holes
Die Casting	3-D configuration lower piece price	tools are expensive high piece price high amount of scrap may have large voids usually a lot of secondary
Plastics	lower piece price increased design flexibility	lower strength high tooling cost less stable material
