Process

Metal Injection Molding (MIM)

Definition

A powder metallurgy process that mixes fine metal powder with a thermoplastic binder, injects the feedstock into molds, then removes the binder and sinters the part to near-full density.

How MIM works

  1. Feedstock — 304 stainless powder + binder compounded to injection-grade pellets
  2. Molding — Complex geometries molded like plastic at high cavitation
  3. Debinding — Thermal or solvent removal of binder
  4. Sintering — High-temperature furnace densifies to >98% theoretical density

MIM is ideal for high-volume, complex stainless components that would require multi-axis machining from bar stock.
