Comparison of MIM and CNC:
Same: Both are suitable for producing products with complex three-dimensional structure and high precision requirements.
Differences: 1. Cost of complex parts: When the product complexity is extremely high, CNC calculates the price on time, and the cost is higher than MIM;
2. Production of ultra-small parts: CNC is restricted by the blade and cannot produce ultra-small parts, but MIM is suitable for the production of small parts;
3. Production of ultra-thin parts: CNC is subject to clamping, and products with a wall thickness of less than 1mm are easy to deform, and MIM can produce ultra-thin parts;
4. Mass production: In small batch production, CNC production efficiency is high; in mass production, MIM production efficiency is high.
CNC and MIM are not entirely a substitute relationship, but also have a complementary relationship. For example, there is a CNC process in the post process of MIM.
