Investment mold precision casting valve body is a casting method compared with sand mold casting precision casting process. The appearance is more accurate and the casting precision is greater. What is the more common method: Before the specific application of the electrical grade leaching mold to produce the inner wall, the desired blank (able to leave a particularly small volume or no volume) of the electrical grade is made. Then, in order to obtain the original wax mold, the casting wax is cast according to the casting. Heat-resistant liquid sand is layered on the wax mold on a dust cup. A cavity consistent with the desired blank is obtained, with sufficient thickness, dried, reheated and the wax mold dissolved. Then casting steel liquid in the cavity, dry manic solid and then decrusted, you can get the finished product of precision machinery manufacturing.

Lost wax casting is now known as sand casting precision castings, investment casting is an excellent production process for steel enterprises with wide application and little or no cutting of perforation. Not only for a variety of metal casting, and casting specifications accuracy, surface quality than other casting methods, even other casting methods can not cast complex, heat-resistant, not easy to produce casting, you can choose sand mold casting precision casting.
