The Benefits of Metal Injection Moulding
For sectors or industries in need of high-volume small parts, Metal Injection Moulding (MIM) is ideal, being cost-effective and producing intricate, complex parts with a great level of accuracy.
Dependant on shape, another benefit of metal injection moulding is that it’s able to replace a set or assembly of two or more parts with a single MIM part, cutting the cost of producing different parts, assembling and machining them.
Metal injection moulding process offers many advantages including:
- Production of complex and intricate shapes
- Low piece price for high volume production
- Excellent dimensional accuracy
- Exceptional surface finish
- Machining generally eliminated
- Consistency and repeatability
- High part integrity

Metal Injection Moulding Process Explained
The process of MIM was first developed in the 1970s by Raymond Wiech in the US, but it has only been used commercially in the last twenty years. A completely different manufacturing process to die-casting and similar to the moulding process used for plastic parts, MIM compresses fine metal powder particles under high pressure in steel tooling to create the component shape. The “green” parts are then passed through a furnace under a controlled atmosphere to produce the finished part. The accuracy of the process generally negates the need for post machining.
- A two part steel tool is cut directly from the 3D CAD data
- Metal powder injected into the tool
- Powder is compressed under hydraulic pressure
- “Green” part is “sintered”
- Heat treatment and other post processes as required
