Do MIM has Special Requirements for Tooling?

Moulds for metal injection molding(http://www.zcmim.com/) suffer more serious erosion wear than general plastic injection. Wear resistance is one of the most basic requirements for mass production by metal injection mold cavity. General required hardness of cavity is 58~62HRC. Under injection temperature, metal injection molding often produce corrosive gases. Hence corrosion resistance is also a certain requirement for mold material. In order to obtain good fluidity for feeding, MIM material applied low molecular weight and binder. It make MIM feeding flash high sensitivity, similar to the characteristics of many nylon materials. So MIM mold must have high accuracy, no flash, high surface quality and quality requirements.
