MOKO Metal Injection Molding
Metal injection molding, also known as “powdered injection molding”, is a metal forming technique that applies injection mold machines to manufacture metal parts with various shapes to tight tolerances. It can produce metal parts in large quantities one time by simple steps, as there are multiple cavities in the injection machine, but the limitation is that the quantities of products per “shot” should not be over 100 grams, so metal injection molding is the best choice for making small metal items. It is much popular, and the finished metal components are used in many industries and applications such as electronics, automotive, aerospace and so on.

How Does Metal Injection Molding Work?
The raw materials of metal injection molding are metal powders and thermoplastic binder, the powder can decide the properties of the final metal injection molded products, as the binder is just an intermediate processing aid and need to be removed once the injection molding is finished. And the mixed material is called feedstock, which is normally formed with granule sizes of several millimeters.
2. Injection Molding
The feedstock would be injected into the injection machine, it can be molded to different shapes ranging from simple to complex shapes, and we call the molded part as the “green part”, which would be taken out of the mold when it cools enough.
This step can remove the binder by using different methods, for example, we can use a catalytic process or thermal furnaces. This process can only remove part of the binder, there is still some binder in the parts that can be removed totally in the following sintering process, which is a method to form and compact materials by using pressure and heat.
The sintering process can eliminate the pore volume that is occupied by the binder before, so there would be a linear shrinkage of about 15-20% of the metal injection molding parts. And the sintered metal parts can be processed further by using some traditional metal processing methods like heat treatments that are used for casting components.
The Advantages of Metal Injection Molding Work
Large Production Volumes
There are many cavities in one injection molding machine, which means it can manufacture a lot of products at one time. In addition, the mold can be used repeatedly, so it can manufacture metal components in large volumes, from hundreds to thousands. Metal injection molding is a perfect technique for projects with huge quantities.
Nice Surface Finish
The surface of metal injection molded products is smooth, there are no burrs or tooling marks on the surface, which can save a lot of time as no secondary processing is needed.
Versatile Shapes Supported
Metal injection molding can mold metal parts with a variety of shapes, no matter how complex the shape is. What’s more, the shape and sizes are very accurate as the pressure to inject the material into the mold is high enough to make sure it can fill the mold in every corner.
Minimal Metal Waste
During the process of metal injection, the metal waste is less except when mold production and debinding. There is no need to cut away excess material once injecting the feedstock into the mold, so it is also a very environmental technique.
