Utilizing this new method, it is possible to bond Metal Injection Molded (MIM) parts through sinter bonding to a conventional substrate. In MIM, fine metal powders are mixed with a binder and injected into molds, similar to plastic injection molding. After demolding, the binder is removed from the part, and the compact is sintered to almost full density. This method achieves bond strengths between 150 to 450 MPa, which is up to 80% of the strength in resistance welds. Additionally, functionally designed composite assemblies can now be created through this method (e.g., high-wear areas on large assembly, magnetic–nonmagnetic assemblies, conductive/insulated assemblies) and feasibly manufactured.
• Competitive bonding strength similar to resistance welding.
• Flexibility of materials.
• Feasible integration into current manufacturing practices.
• Implemented in critical areas of larger parts at a lower overall cost.
• Reduces susceptibility to cracking.
• Improved shear strength over comparable methods.
