Metal Injection Molding (MIM) design alteration involves making modifications to an existing design in order to optimize it for MIM manufacturing. Here are some considerations for MIM design alteration:

1. Geometry: Altering the geometry of a part can optimize it for MIM manufacturing. For example, adding draft angles to reduce tool sticking or reducing wall thickness to improve flow can improve part quality and reduce manufacturing costs.
2. Material selection: Changing the material used in a MIM part can improve its performance or functionality. For example, switching to a different metal or alloy can improve corrosion resistance or strength.
3. Tolerances: Adjusting the tolerances of a part can help to improve its manufacturability and reduce production costs. Tightening tolerances can increase part accuracy but may also increase the likelihood of scrap parts.
4. Surface finish: Altering the surface finish of a part can improve its aesthetics, wear resistance, or functionality. For example, adding a coating or textured finish can improve grip or reduce wear.
5. MIM-specific design guidelines: Adhering to MIM-specific design guidelines can help to optimize a part’s manufacturability and performance. For example, optimizing part symmetry or minimizing wall thickness variation can improve part quality and reduce warping.

When considering MIM design alteration, it is important to work closely with an experienced MIM manufacturer to ensure that the design changes are optimized for the specific MIM manufacturing process being used. By considering these and other design factors, it is possible to optimize a MIM part’s manufacturability, performance, and functionality through design alteration.
