As can be seen on the graph, MIM is an unrivalled technology for the production of large volumes of small parts with high levels of geometric complexity and mechanical performance.
MIM is a novel manufacturing technology that allows highly complex parts to be obtained completely reliably and precisely, with mechanical properties similar to those of any machined, microfused or laminated materials.
The Metal Injection Moulding production process combines the advantages of sinter processes with the flexibility of processes that use thermoplastic injection. It provides a vastly superior quality than either process and achieves densities that can be as high as 99%.
When can MIM technology be used?
The main characteristics that identify a part as being suitable for this process are shown in the following table:
