Investment casting also can be called "precise casting" or " lost wax casting" or "de-waxing casting", its products are precise, complex, close to the final shape of the part, and can be directly used, so investment casting is an advanced process of near-net shape formation.

Ancient China: Wang Ziwu tripod, copper ban, copper lion, etc., are masterpieces of investment casting. Since investment casting was used in industrial production in the 1940s, it has been developing at a faster rate in half a century. In particular, European and American countries are developing rapidly. Investment casting is used in aviation, weapons sectors, almost all industrial sectors, especially electronics, petroleum, chemical, energy, transportation, light industry, textile, pharmaceutical, medical equipment, pumps and valves and other sectors.

The development of investment casting technology enables investment casting to produce not only small castings, but also larger castings, the largest investment casting profile size is nearly 2m, and the minimum wall thickness is less than 2mm. At the same time, investment castings are becoming more precise, and in addition to linear tolerances, parts can also achieve higher geometric tolerances. The surface roughness of investment castings is also getting smaller and smaller, reaching Ra 0.4 μm.

The casting materials can widely used, and no limitation for product shape as well as complex structure. The most important characteristic is the closely tolerances control, reduced machining allowances, and fine surface finish. Its application scope can be wider after using the new equipment and advanced technology. In heat processing industry, investment casting can be used for those products which difficult to choice the materials, or materials not easy to form a shape, as well as some forging pieces with higher cost; while in the casting industry, the investment casting can be used instead of other casting methods, so as to reduce machining allowances and the cost, improve the dimensional precision and surface finish as well as the mechanical properties, so as to meet the requirements of a higher level product.
