Overview
Metal Injection Molding (MIM) is a cutting-edge manufacturing process that combines the design flexibility of plastic injection molding with the strength and integrity of wrought metals. It is the ideal solution for producing small, complex, and high-precision metal parts in large volumes.
Key Advantages of MIM
• Complex Geometries: Capable of producing intricate shapes that are difficult or impossible to achieve with traditional CNC machining.
• High Volume Efficiency: Most cost-effective for production runs ranging from thousands to millions of parts.
• Excellent Material Properties: Achieves near-full density (96%-99%), providing mechanical properties comparable to wrought materials.
• Material Savings: Near-net shape manufacturing significantly reduces material waste.
Materials We Support
• Stainless Steel: 304L, 316L, 17-4PH, 420, 440C.
• Low Alloy Steel: 4605 (FeNi7), 4140.
• Soft Magnetic Materials: Fe-Si, Fe-Ni.
• Tool Steels: M2, SKD11.
• Tungsten Alloys & Titanium: Available upon request for specialized applications.
Technical Specifications
• Tolerance: Standard ±0.3% to ±0.5%, with tighter tolerances achievable through post-machining.
• Surface Finish: Ra 0.8 - 1.6 μm (as sintered), can be further improved by polishing or PVD coating.
• Part Weight: Typically 0.1g to 250g.
Applications
Our MIM parts are widely used in:
• Consumer Electronics: Smartphone hinges, internal brackets, wearable device components.
• Medical Devices: Surgical instruments, orthodontic brackets.
• Automotive: Turbocharger components, sensor housings, lock mechanisms.
• Tools & Hardware: Professional hand tools, specialized fasteners.
