Fabrication

The nickel steel MIM part features extremely close tolerances and a complex geometry requiring an elaborate tool design. The sight allows the shooter to target objects at ranges up to 183 m (600 ft.) by using the larger aperture and to target objects at longer ranges by flipping the sight down and using the smaller aperture. The part is made to a density of 7.5 g/cm³ and has an as-sintered ultimate tensile strength of 380 MPa (55,000 psi).

Results

• Choosing the MIM process over investment casting provided a 40% cost savings. This part is traditionally manufactured through investment casting process followed by significant and expensive secondary machining operations.
• Return on tool investment for customer in less than one year
