MIM stands for Metal Injection Molding, which is a manufacturing process that combines the benefits of plastic injection molding and powder metallurgy to produce complex-shaped metal parts with high precision and consistency. MIM tooling refers to the tooling or molds used in the MIM process.

MIM tooling is typically made of steel and is designed to withstand the high temperatures and pressures required in the MIM process. The tooling is made up of two halves, the cavity and the core, that are designed to create the desired shape of the final part. The tooling can also include additional features such as slides, lifters, and inserts to create more complex parts.

MIM tooling can be expensive to produce due to the precision required in the manufacturing process. However, once the tooling is created, it can produce large quantities of parts with high accuracy and consistency. The cost-effectiveness of MIM tooling depends on the complexity of the parts being produced and the volume of production.
