Advice on MIM design
1.Integration
2.Avoiding parts with a thick wall
Because a part with a thick wall is likely to have a molding defect and/or a debinding fault, it is leveled (approximately 1.5 to 2.5 mm) by thinning, ribbing, or other means.
3.Leveling and weight reduction
4.Corner radius
When contracting with low strength, a tensile force is easily generated at the interior angle radius. A small radius is added to disperse the force.
5.Example of weight reduction
Composite
Joining the same materials | Achieving thick products for which MIM is difficult (For MIM, it is normally difficult to manufacture a product with a thickness of 5 mm or more in terms of molding and debinding.) |
---|---|
Achieving undercut products for which metal tooling cannot be molded integrally (example: hollow parts, etc.) |
