Rolling Steel Nut

Advanced technology with sand mold casting, centrifugal casting, metal mold casting, investment casting and other casting process, can according to customer requirements, according to the requirement of the workpiece material and process select the most appropriate casting technology, good services to customers.The company has a perfect and scientific quality management system;The quality inspection system, such as the improved component testing and mechanical performance testing, etc. Problem of bearing:It is known that copper tile has high hardness and good wear resistance. It is not easy to bite dead, and it has good casting performance and cutting performance.It has extremely strong corrosion resistance.Then it is also quite careful in the process of manufacturing, so what should we pay attention to during the process of manufacturing process?The first point: at the time of casting copper tile, each working procedure is must be carefully handled, such as box request to put is the core, to avoid get cast out a product for this reason that they cannot finish to size.The second point: first, to clean up before processing copper tile casting, and then get on the bus, correct first, and then processed into semi-finished products out of the car, cooling, because copper contractility, in order to machining precision DaiGong pieces placed at room temperature to get on the bus.Third point: after the finished product, place cannot be placed vertically, prevent deformation.
