The future development trend of cemented carbide MIM


Cemented carbide has high hardness, high strength and high wear resistance, so it is widely used as a variety of cutting tools and a variety of wear-resistant parts. Because of the high cost of traditional pressing and sintering method, the shape of the products is simple, the machining is difficult, and the application of the hard alloy is limited. Injection molding is a near net shape technology, with high productivity, products with complex shapes, low cost. Therefore, hard alloy injection forming technology and development will expand the scope of application of the hard alloy.

At present, the MIM of cemented carbide process has successfully produced products include hard alloy cutter [42,43], micro drill, centrifugal device, nozzle, all pump parts, piston, a filter, a various kinds of sports activities, textile machinery with wire. In recent years, people directly use the aesthetic value of MIM products, production of the golf club head, watchband, watchcase and other products. The future will be a breakthrough in the nameplate LOGO, jewelry, arts and crafts.

The development of MIM technology has a great influence on the production of cemented carbide products. Superior product performance, low cost of production and the potential high profit margins will attract more and more producers and users of concern and join.


As hard alloy manufacturers have been very familiar with the process of fat, sintering and other processes, so they are still the main force for the development of cemented carbide injection molding technology. It can be predicted that the near future, with in-depth understanding of the designers and users of hard alloy injection forming technology, along with the gradual improvement of the properties of the products, hard alloy injection forming will have broad market prospects, will bring considerable economic benefits, is following after the forming of the stainless steel injection powder injection forming new development hot spots.
