MIM

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.)

Example of joining
