Medical industry: In recent years, the medical industry has developed rapidly, and the demand for medical equipment has also kept growing. However, the capacity of the traditional machining technology is unable to meet the increasing demand for metal structural parts. The MIM technology, by virtue of the high productivity and high accuracy of mold injection as well as much lower cost than the traditional machining technology, well meets customer needs and develops quickly. At present, the MIM technology has been successfully used in the fields of ultrasonic knife, clip applier, biopsy instrument, anastomat and soon, and will gradually replace other traditional processes in the future.
