Design for Manufacturing (DFM) is one of the best practices our engineers follow to ensure your part does not require expensive secondary operations which can often represent as much as 80% of the component cost. Our engineers use a DFM methodology that optimizes manufacturability while preserving functionality. 

  • Sintering Supports

    To avoid distortion of parts, ideal MIM designs have a large flat surface or with several component features that have a common plane allowing for the use of standard or flat debinding and sintering supports.

  • Draft

    This is a design aspect where MIM often differs from other injecting molding requirements. Some MIM components can be designed with little or no draft.

  • Fillets & Radii

    Fillets and radii provide our design engineers with design advantages in MIM which are not readily available in other metalworking processes.

  • Ribs & Webs

    Our designers use ribs and webs to increase your component strength, and minimize the effects of dimensional variation.

  • Gating

    Our designers carefully consider the impact of the gate location on a component during the design phase, carefully balancing manufacturability, part function, dimensional control and aesthetics.

  • Interchangeable Mold Inserts

    Multiple parts which have only minor variations between them may be produced using interchangeable mold inserts, minimizing the tooling fabrication needed and providing tooling cost savings.

  • Dimensional Tolerances

    As a starting basis, MIM is capable of as-sintered tolerances of +/-0.3% of nominal (i.e. 1.000” +/-.003”). To minimize the cost of secondary operations, the general tolerance guidelines should be applied.
