Metal injection moulding (MIM) is a state-of-the-art manufacturing process that combines the best features of powdered metallurgy and plastic injection molding. However, unlike its beloved plastic counterpart (invented in the 1870s), MIM was developed in the 1960s and has only recently begun to gain popularity in a variety of industries.
In the metal injection moulding process, metal powder is mixed with a plastic binder to create a “feedstock” that can be injected into a mould just like plastic. Once the part is cooled and the binder is removed, you’re left with a high-quality metal part that has all of the intricate details of the original mould.
MIM has many advantages over traditional methods of manufacturing metal parts, such as machining or die casting. Here are just a few of the reasons why MIM is quickly becoming the preferred method for creating small, intricate metal parts:
MIM parts can be much more complex and detailed than those made with traditional methods. That’s because the injection moulding process allows for very tight tolerances, meaning that your parts will have a consistent size and shape. Generally speaking, any structure or shape that can be achieved using plastic injection moulding can be replicated in steel by MIM.
MIM is also more cost-effective than other methods of manufacturing metal parts. That’s because you can produce more parts in less time, and with less waste. In addition, MIM parts require less post-production finishing than those made with other methods, which further reduces your costs.
MIM parts are also stronger and more durable than those made with other methods. That’s because the injection moulding process evenly distributes metal powder throughout the entire part, which results in a stronger final product. Additionally, MIM parts are less likely to warp or deform over time thanks to their consistent size and shape.
If you’re looking for a cost-effective, efficient way to manufacture small, intricate metal parts, then metal injection moulding (MIM) is the perfect solution for you. Thanks to its many advantages over traditional methods, MIM is quickly becoming the preferred choice for businesses across a wide range of industries. So why not give MIM a try for your next project? You might be surprised at just how well it works!
