Benefits of MIM
- Metal injection molded parts can be shaped in one step, eliminating secondary processing costs.
- MIM parts have a fine surface finish, making them ideal for products with high aesthetic requirements, such as watches and mobile phones.
- Metal injection molded products have a higher density than conventional powder metallurgy parts.
- MIM is suitable for mass production and for manufacturing complex parts with intricate features.
- MIM achieves a material utilization rate of over 95%, saving resources and costs.
MIM Parts Manufacturing Process
Metal Injection Molding (MIM) process consists of multiple and complex steps. Fortunately, BLUE has over 10 years of experience in designing and manufacturing MIM parts. Our products are widely used in the automotive, power tools, medical, and electronics industries, delivering exceptional quality and precision for your needs.
Designing
MIM parts design needs to consider numerous factors such as material selection, part geometry, wall thickness, sintering shrinkage, etc.
Tooling
The feedstocks enter the hopper, pass through the feed barrel, and are injected into the mold by the injection molding machine to form green parts.
Mixing
Metal powder and binder are mixed in a ratio of 60:40 to form the raw material, called "feedstock". Binder makes metal powder have better fluidity and adhesion.
Injecting
The feedstocks enter the hopper, pass through the feed barrel, and are injected into the mold by the injection molding machine to form green parts.
Debinding
Debinding is to remove the binder in the green parts. Debinding processes include thermal debinding, solvent debinding, catalytic debinding, etc.
Sintering
Sintering heats the components to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.

Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
Metal injection molding covers multiple processes, such as mixing, injection, degreasing, sintering, secondary processing, etc., and it takes about 20-30 days
MIM parts utilize fine metal powder and high-cost molds, making the initial investment substantial. Additionally, the required equipment includes injection molding machines, degreasing units, sintering furnaces, and secondary processing machines. Consequently, MIM offers a price advantage primarily in mass production scenarios.
MIM parts utilize fine metal powder and high-cost molds, making the initial investment substantial.
We use secondary operations to improve the mechanical properties, dimensional accuracy and surface appearance of sintered MIM parts, including machining, heat treatment, embossing, machining, surface treatment and hot isostatic pressing.
