Therefore, this technology is known as "the most popular component molding technology today" and is widely used in aerospace, medical equipment, smart wearables, machinery industry, automotive industry and other fields. Although metal powder injection molding technology can form three-dimensional parts with complex structures, the green body contains high molecular polymers that will be decomposed during the degreasing and sintering process. At this time, the size of the parts will shrink. The parts obtained by the sintering process will inevitably have certain deviations in shape and size. Therefore, in order to make the parts with shape and size deviations meet the design standards, they need to be shaped.
