Advantages of dewaxing casting process

useDewaxing castingIt is characterized by the ability to combine thin-walled parts, complex-shaped parts, pattern precision castings, difficult-to-machine parts, shape precision castings, material-expensive castings and multiple castings into one, and the dimensional accuracy and surface gloss are very good. Especially for parts with peculiar, hollow and complex shapes that are difficult to be processed by traditional sand casting, forging or cutting methods, although forging, cutting and other methods can also be used for processing, but the procedures are very numerous, requiring a lot of machining, and the productivity is low. , At the same time, it consumes a large amount of metal materials, and the manufacturing cost is high. It can be changed to dewaxing mold casting, which can achieve the purpose of short construction period and low cost.

Generally, the process conditions for the production of this part by dewaxing casting method are: using dewaxing precision casting method to produce some alloys, the effect will be better. For example, complex composite parts can be precision casted with holes, grooves, bevels, serrations, and recesses on the surface. Because of the very good dimensional accuracy, more than 90% of the parts can be used without reprocessing, so the finished milling, turning, boring and other machine tools can be used. Product development, The design is also very good.
