MIM (Metal Injection Molding) is a near-net-shape manufacturing process that combines plastic injection molding with powder metallurgy.
It is ideal for producing small, complex, high-precision parts with intricate 3D geometries.
l Advantages:
① High design freedom
② Excellent dimensional accuracy
③ Good mechanical strength
④ Cost-effective for high-volume production
l Comparison:
① CNC: Suitable for simple geometries and low-volume production, but has higher costs and lower efficiency for complex parts.
② Die Casting: Capable of producing larger parts, but generally offers lower precision, strength, and thinner wall capabilities compared to MIM.
③ Stamping: Limited to 2D flat or formed sheet metal parts; cannot produce complex 3D shapes.
l Stainless Steels: 304, 316L, 17-4PH.
l Iron-based Alloys: Fe-Ni, Soft Magnetic Alloys.
l Tungsten Alloys, Titanium Alloys (select grades).
l Low-Alloy Steels, Tool Steels.
l etc.
l Standard tolerance: ±0.03mm to ±0.05mm.
l High precision: Can achieve ±0.01mm to ±0.02mm, depending on part geometry and size.
l Note: Tolerances may be relaxed for larger parts or more complex geometries.
