MIM process characteristics

MIM combines the advantages of powder metallurgy and plastic injection molding technology, breaking the limit of the traditional metal powder forming process in the shape of the product. MIM using metal powder technology can be characterized by sintering out of the dense, with good mechanical properties and surface quality of mechanical parts.

At the same time, the use of plastic injection forming technology can mass, high efficiency to produce many parts with complex shape features: such as a variety of external grooving, external thread, the tapered outer surface, cross through hole and blind hole and concave part and the pin key, strengthen rib plate, surface knurling and so on, parts with the above characteristics are inaccessible by conventional powder metallurgy method, precision casting process are obtained.

MIM hardness test

MIM commonly used hardness test method has a lot of different hardness measurement methods have their own characteristics and scope of application. The more commonly used is the hardness of Vivtorinox hardness;

The hardness value of HRC can be directly read out, the operation is simple and quick, and the work efficiency is high. However, due to the production of diamond head and measuring mechanism of poor accuracy, the accuracy of the precision is not as good as Vivtorinox. Suitable for bulk parts inspection, can be on-site or production line on the finished product testing.

Vivtorinox hardness; hardness measurement range of Vivtorinox, hardness value of HV, not only can measure the hardness of materials, but also can measure the soft metal and sheet, strip, with high accuracy. But the measurement efficiency is low.
