Design Guidelines of Metal Injection Molding (MIM) Components

In the intricate landscape of Metal Injection Molding (MIM), our unwavering commitment to excellence is underpinned by a holistic application of Design for Manufacturing (DFM) principles. This meticulous approach ensures not only the sophistication of your components but also their optimization for cost-effective and reliable production. Let’s delve into the nuanced facets of our design philosophy:

  1. Sintering Supports for Distortion-Free Precision:
    • Ideal MIM designs strategically incorporate expansive flat surfaces or components with shared planes, allowing seamless integration with standard debinding and sintering supports.
    • Given the approximately 20% shrinkage during debinding and sintering, the design emphasis on large flat surfaces mitigates potential distortion, preventing gravitational and frictional forces from compromising precision.
    • Prioritizing such designs facilitates the use of standard supports, steering clear of the expenses associated with custom supports and additional tooling costs.
    • Specialized supports, including ceramic strips and molded-in supports, come into play when the design necessitates more intricate solutions.
  2. Draft Strategies for Effortless Ejection:
    • Unlike conventional injection molding, MIM components may require minimal or zero draft angles.
    • Contributing factors to this capability include the prolonged heat retention of metal-powder-loaded MIM feedstock and post-molding shrinkage.
    • The polymer binder within MIM feedstock acts as a lubricant, streamlining the ejection process.
    • Incorporate draft angles in the design to facilitate easy ejection of the molded part from the tooling.
    • Adequate draft angles minimize friction, reduce tool wear, and enhance the overall efficiency of the molding process.
  3. Fillets & Radii: Elevating Design Sophistication:
    • Fillets and radii emerge as design cornerstones, offering distinctive advantages not easily attainable in alternative metalworking processes.
    • These features not only bolster part strength but also eradicate stress concentrations, contributing to enhanced aesthetics and user-friendly handling.
    • Maintaining corner breaks with a radius larger than 0.005” is recommended to avert stress concentrations and fabrication challenges.
    • Minimize sharp corners and edges to prevent stress concentration points and potential cracking during processing.
    • Rounded edges contribute to improved part strength and durability.
  4. Ribs & Webs: Fortifying Strength and Dimensional Stability:
    • The strategic integration of ribs and webs in designs serves to amplify component strength and counteract the effects of dimensional variations.
  5. Gating Strategies for Holistic Design Balance:
    • Gate location assumes a pivotal role in the design phase, undergoing careful evaluation to strike a harmonious balance between manufacturability, part functionality, dimensional precision, and aesthetic appeal.
  6. Minimizing Sink & Knitlines for Unparalleled Quality:
    • Our collaborative DFM process is dedicated to minimizing sink and knitlines, ensuring a superior quality finish for the final components.
  7. Optimizing Wall Thickness for Structural Integrity:
    • Determining the ideal cross-sectional wall thickness, whether minimum or maximum, is intricately linked to the overall part size and design intricacies.
    • Maintain uniform wall thickness to ensure consistent material flow during the injection molding process.
    • Avoid abrupt changes in thickness to prevent issues like warping and sink marks, ensuring a homogenous structure.
    • Maintain consistent wall thickness to ensure uniform heating and cooling during the sintering process.
    • Consistency in thickness enhances the mechanical properties and overall quality of the final component.
  8. Addressing Flash & Witness Lines for Aesthetic Integrity:

  9. Interchangeable Mold Inserts: Maximizing Cost Efficiency:
    • Streamlining production for parts with minor variations is achieved through the implementation of interchangeable mold inserts, a strategy that minimizes tooling fabrication costs.
    • Optimize part size and complexity to align with the capabilities of MIM equipment and tooling.
    • Consider breaking down larger, more complex parts into smaller, manageable components for enhanced efficiency.
  10. Dimensional Tolerances for Precision Production:
    • MIM boasts as-sintered tolerances of +/-0.3% of nominal, establishing a robust foundation for reliable and precise components while mitigating the need for extensive secondary operations.
    • Understand and design within the achievable tolerances of the MIM process.
    • Specify critical dimensions and tolerances to meet functional requirements without compromising cost-effectiveness.
  11. Material Selection and Compatibility:
    • Opt for materials inherently compatible with the MIM process, typically involving fine metal powders mixed with binders.
    • Thoroughly assess material properties, including shrinkage rates during debinding and sintering, ensuring the preservation of dimensional accuracy throughout the manufacturing journey.
  12. Undercut Design for Features:
    • Leverage MIM’s unique capability to produce undercuts without the need for secondary operations.
    • Strategically incorporate features like threads, holes, and intricate surface textures that might pose challenges or incur high costs with alternative manufacturing methods.
  13. Post-molding Processes Integration:
    • Plan for essential post-molding processes, such as debinding and sintering, at the design phase itself.
    • Anticipate and accommodate any dimensional changes that may transpire during these processes, allowing for seamless adjustments to the initial design.
  14. Labelings and Engravings Integration:
    • Explore diverse possibilities for labelings and engravings to enhance the functionality and aesthetics of MIM components.
    • Choose between protruding or recessed labelings based on design preferences.
    • Incorporate company logos, symbols, article numbers, text fields, warnings, and production dates (month, year) strategically into the design.
    • Integrate labeling elements seamlessly, ensuring they complement the overall design without compromising functionality.

In essence, our design principles in MIM go beyond the superficial, ensuring not only the visual allure but also the feasibility, efficiency, and steadfast reliability throughout the manufacturing journey.
