MIM process is suitable for mass production of small, precise, complex three-dimensional shape and metal parts with special performance requirements. Over time, only tools and technologies have changed, and people's needs have not changed much. When the tools and technical capabilities of the MIM industry are improved, this technology can meet the requirements of parts in more fields, such as automobile, aerospace, medical, 3C, etc.

The evaluation process is from raw materials to finished products. It needs to consider the comprehensive product performance structure, use environment, cost, materials, manufacturing feasibility, etc. At the same time, MIM enterprises will advise customers to change the design so as to achieve the optimization effect through MIM.

Generally, the products selected for MIM process evaluation have the following commonalities.

1. Total demand: Mold cost and R&D cost are hard to bear for products with low demand after apportionment. Therefore, when the annual demand of products reaches or exceeds 20000 pieces, MIM process can be considered.

2. Materials: MIM process is a near net forming technology. For parts designed with hard to cut materials such as titanium, stainless steel and nickel alloy, MIM is the most attractive.

3. Quality and cutting amount: For parts with very high material consumption and time-consuming processing in cutting and grinding, MIM has great advantages in reducing production costs.

4. Performance: Based on the high density of MIM products, if the performance is required, the performance formed by the high density of MIM products is competitive.

5. Product complexity: MIM process is most suitable for manufacturing multi axis parts and multi datum parts with complex geometry and many machining stations need to be changed during cutting.

6. Combination: In order to save inventory and assembly costs, it can be seen that multiple parts are consolidated into one part.

7. Tolerance (accuracy requirement): The tolerance of MIM sintered parts is about ± 0.3%. If the tolerance required by the product is very strict, MIM sintered parts need to be processed again, such as CNC, CNC lathe, etc. The cost of MIM also tends to increase, which requires evaluation and comparison.

8. New composite materials: MIM can produce new composite materials that are difficult to manufacture by traditional processes, such as laminated or two material structures or mixed metal ceramic materials for wear resistance.
