The difference between die casting and investment casting

There are many kinds of castings,according to modeling methods,can divide into two kinds as follows:1.Ordinary sand casting ,include 3 categories :wet sand and dry sand and chemical hardening sand ; 2.Speical casting,according to modeling material can divide into special casting with natural mineral aggregate as main molding material such as investment casting ,loam moulding,shell casting of foundry shop,negative regulation;continuous casting, low pressure casting, centrifugal casting etc.
 
Through the above, we can see that the precision casting is a special casting category.Die casting: pressure casting for short, is a kind of the molten alloy liquid into the pressure chamber, with the high speed filling steel mold cavity, and the alloy liquid and the formation of casting method of the solidification of the casting under pressure. The main characteristics of die casting casting method is different from other high pressure and high speed.
 
Investment casting: precision casting, is a special casting. The parts obtained by this method generally need no further machining, such as investment casting, pressure casting and so on and special casting with metal as the main casting material,such as metal mold casting, pressure casting, continuous casting, low pressure casting, centrifugal casting etc.

The main characteristics of die casting casting method is different from other high pressure and high speed.
 
Casting: precision casting, special casting. Obtained by this method is generally not subject to the parts machining. Such as casting, pressure casting. Casting method is compared with the traditional casting process is concerned. It can get relatively accurate shape and high precision casting.It can get relatively accurate shape and high precision casting.The more common approach is: first according to the requirements of the product design (can be very small or no allowance) with the method of casting mould, casting wax, get the original wax;Repeated coating and sanding process in wax, hardening shell and drying; then the wax is melted into dewaxing, get cavity;Roasting shell to obtain sufficient strength; metal casting materials needed; after the shell sand cleaning, so as to achieve high precision of finished product, according to product requirements or heat treatment and cold.
 
 
Wax casting: wax casting method.First appeared in the spring and Autumn period, the whole manufacturing process is manual operation.The process of it is: the wax to type style production, after the high temperature fine mud spray to the surface wax, and then spinning in the mud surface, repeatedly, to form a complete shell after drying, heating the wax melting, forming cavity for casting molten copper (i.e., copper and lead, zinc, tin and other metal elements in solution).Finish after casting, deshelled, polish, do the old, one of the antique bronze exquisite beyond compare on the show in front of you. The lost wax precision casting is called investment casting, precision casting process is a little or no cut cutting, is an excellent technology for precision casting industry the wide range of applications.It is not only suitable for various types of precision casting , and production of casting dimension, surface quality is higher than that of other precision casting method, and other precision casting method is difficult to cast  the complex, high temperature resistant, not easy machining castings, can be used in investment casting .
