Brass Casting Parts

In industrial manufacturing or life, you will see many brass parts, most of which are made by investment casting. For example, many accessories such as brass jewelry, brass pendants, brass ornaments and so on that are common in our lives are produced by investment casting. The casting performance of brass in copper alloys is relatively good, but its shrinkage is relatively large, and it is prone to shrinkage holes, cold cracks, deformation and other problems. It is necessary to reduce the pouring temperature as much as possible in the actual pouring to improve this problem. Of course, there are many other processes to improve this shortcoming, such as selecting a good sand mold, setting a riser, or setting a gating system, etc., which can be improved, and the details are discussed and analyzed according to the structure of the workpiece.

Brass casting is not only used in jewelry, pendants, ornaments and other handicrafts in daily life, but also widely used in industry, because copper itself has good corrosion resistance and superior conductivity. There are also many brass castings produced by SCZY. The common ones are some handicrafts, some architectural accessories, and auto accessories. We also support secondary precision CNC machining and surface treatment. Let customers have no worries.
