     Precision Casting is a casting method relative to the traditional casting process. It can obtain relatively accurate shape and high casting precision. The more common practice is: first make the required blanks (the left margin is very small or leave no margin) of the electrode, and then use the electrode to corrode the mold body, forming a cavity.Precision Investment Casting
     Then cast the wax to obtain the original wax mold. In the wax mold on a layer of high temperature-resistant liquid sand. After getting enough thickness to dry, then heating, so that the internal wax mold dissolved, to obtain the same type of blanks as required. Again in the mold cavity casting molten iron, after curing the shell will be stripped off, you can obtain precision manufactured products.Precision Investment Casting
      The lost wax method casting is now called investment casting precision casting, is a kind of less cutting or no cutting process, is a casting industry's excellent technology, its application is very extensive. It is not only suitable for all kinds of casting of various kinds of alloys, but also produces castings of precision, surface quality than other casting methods, and even other casting methods are difficult to cast complex, high temperature, not easy to process castings, can be used in investment casting precision casting.Precision Investment Casting
       Investment casting is developed on the basis of ancient wax mold casting. As an ancient civilization, China is one of the earliest countries to use this technology, far away from BC hundreds of years, the ancient people of China created this lost wax casting technology, used to cast a variety of fine patterns and text of the zhongding and utensils, such as the spring and autumn of the Yi Tomb, such as the plate. Zeng Hou's tomb is the base of many intertwined dragons, they are connected to each other, the upper and lower staggered, forming a middle hollow layer of moire pattern, these patterns are difficult to create with ordinary casting process, and with the loss of wax casting process, can use the paraffin wax without strength, easy to sculpt characteristics, With ordinary tools can be carved with the Yi Tomb to be the same as the wax material of the handicraft, and then add the casting system, paint, dewaxing, pouring, you can get exquisite Yi Tomb of the plate.Precision Investment Casting
