Auto parts are batch processed by moulds, and the manufacture of moulds requires precision moulds and accessories for careful assembly. With the development of high efficiency and automation of automobile production, the demand of automobile mould increases, and the development of automobile industry also needs corresponding development. Not only automobile products, but also many precision machinery parts and components are processed in the society's ever-changing consumer demand, and the updating cycle of products becomes gradually short and the frequency of upgrading becomes faster. In view of such a development trend, hexiang precision co., ltd. in the process of mechanical processing efforts to research and development, innovation, in the development of small batch, variety and other production and processing mode has mature experience. In this way, the processing of mechanical parts can meet the changing market demand.
