FAQ About Metal Injectiom Molding-ONE

1, What’s Metal Injection Molding?

Metal injection molding (MIM) is the latest manufacturing technology that is combined with the flexibility of plastic injection molding and the durability of metal powder.

2, How does Metal Inejction Molding work?

First, mix the fine metal powders and plastic binders to form the feedstock. When heated, it becomes a viscous slurry. Then it’s injected into the tooling under high pressure to form the designed shape. It’s ejected from the tooling after cooling and then is subjected to a process (sometimes we call it debinding) to remove binder. Finally, sintering estimates the remaining binders, then densifies it and gives the part final geometry.

3, Is the metal melted in Metal Injection Molding?

No, only the plastic binders are melted, which makes the metal powder flow well just like melted plastic material.

4, How is the density?

Unlike conventional powder metallurgy, which can achieve only 80%-90% of theoretical density, MIM result in 95%-100% of the theoretical density. Anyway, the characteristic of the MIM parts is almost identical to the raw material.
