What are metal injection molding parts ?
Metal Injection Molding (MIM) is a manufacturing process that combines the design flexibility of plastic injection molding with the strength and durability of metal materials.
It is used to produce small, complex metal parts in high volumes.
Here are some key aspects of metal injection molding parts:
Characteristics:
- Small size: Typically fit in the palm of your hand, ranging from 0.05 to 100 grams
- Complex geometries: Can include overhangs, undercuts, threads, and other intricate features.
- High density: 94-97% of theoretical density, providing near-wrought properties.
- Excellent mechanical properties: Comparable to wrought or forged parts.
MIM parts common applications:
- Automotive: Sensor housings, gear synchronizers, fuel injectors, rivets, fasteners.
- Weapons: Sight mounts, safety levers, firing pins.
- Medical: Endoscopes, laparoscopic devices, implants, dental crowns.
- Consumer goods: Heat sinks, watch cases, buttons, switches, eyeglass frames.

Materials:
MIM can use a wide variety of metal alloys, including:
- Stainless steels (e.g., 17-4PH, 316, 420)
- Low alloy steels
- Superalloys (e.g., Inconel 625, Hastelloy X)
- Controlled expansion alloys
- Tungsten alloys
- Soft magnetic alloys
Advantages:
- High production volumes
- Low cost per part for complex geometries
- High dimensional accuracy and surface finish
- Ability to create very thin walls (< 100 micrometers)
Limitations:
- Best suited for large production batches
- Limited to relatively small parts
- High initial tooling investment.
Design considerations:
- Uniform wall thickness is preferred
- Draft angles needed for easy part release
- Parting lines, gates, and ejector pin marks must be considered
- Cam actions may be needed for undercuts
