Fabrication

Made via metal injection molding (MIM) from 316L stainless steel, each component nests within another component utilizing either locking lugs or fine metric threads to join the assembly seamlessly. The parts have a density >7.6 g/cm³, an ultimate tensile strength of 520 MPa, a yield strength of 175 MPa, an elongation of 50%, and an apparent hardness of 67 HRB.

Results

MIM was the ideal choice, as alternative fabrication methods, such as die casting or machining, could not have provided the precision needed at a reasonable cost, nor been able to provide the required material performance.

• MIM is most effective and efficient with small, high tolerance, and extremely complex components—an accurate description of the three part assembly.
• Necessary geometric details, material strength properties, and end-use precision were achieved while providing the user with an effective customizable product.
• Significantly lower component price—allowed the OEM to enjoy a competitive advantage as it launched its product.
