complexity

Like injection molding, MIM parts (metal powder injection molding) have no restrictions on shape design. Since MIM is a forming process, additional product features will not increase costs, which makes MIM an ideal way to combine independent parts into multi-functional products. MIM design rules are very close to injection molding, so they are applicable to almost all products.

Precision

The reference design of the net forming accuracy of MIM parts (metal powder injection molding 4) is usually ± 0.5% of the size. The net forming of some characteristics can reach ± 0.3%. As with other technologies, the higher the accuracy requirements, the higher the cost. Therefore, it is encouraged to moderately relax the tolerance requirements when the quality allows. The tolerance that can not be reached in one forming of MIM parts can be realized by surface treatment.

Weights and dimensions

MIM parts are particularly suitable for parts weighing less than 100g, and less than 50g is economical for Zui. However, parts weighing up to 250 grams can also be handled. The main cost of MIM parts process is raw materials, so MIM parts can reduce the weight of parts as much as possible through new technologies. Like plastic products, the weight of parts can be reduced through the core and bracket without affecting the integrity of the product. MIM parts are outstanding in terms of tiny and micro components, and it is feasible to weigh less than 0.1 g. Weight is not a limiting factor, and products longer than 250mm can also be processed.

Thinness

Wall thickness less than 6mm is suitable for MIM parts. Thicker outer wall is also acceptable, but the cost will increase due to long processing time and additional materials. In addition, the extremely thin wall less than 0.5mm can also be realized for MIM, but it has high requirements for design.

yield

MIM parts are a flexible process, and the annual output of thousands to millions of demand stars can be realized very economically. Like castings and injection molded parts, MIM parts require customers to invest in mold and tool costs, so for small batch products, cost estimation is usually affected.

raw material

MIM parts can handle many materials, including ferroalloys, super alloys, titanium alloys, copper alloys, refractory metals, hard alloys, ceramics and metal matrix composites. Although nonferrous alloys aluminum and copper are technically feasible, they are usually treated by other more economical methods, such as die casting or machining.
