Application of Metal Powder Injection Molding in Plug-in Locking Device

The plug-in locking device of digital array module (DAM) in a radar is faced with the problems of easy corrosion and high processing cost. The metal powder injection molding (MIM) technology and its application in the production of DAM plug-in locking device are introduced in this paper. A 316L(A) plug-in locking device is prepared by redesigning the structure and adopting the MIM technology, which has successfully solved the problems of DAM plug-in locking device in a radar. MIM technology has advantages in manufacturing near net shaped products with complex shape, high performance, high strength and high precision, which provides more freedom for product design and ensures the realization of integration of plug-in locking device and multi-feature structure design.
