Precision Casting Development Prospect
Feb 09, 2018

Revestment precision casting is refers to the use of fusible materials meltability model, on which the coated with several layers of special refractory coating, after drying and hardening type to form a whole shell, reoccupy steam or hot water from the melt in the shell model, and then put type shells in the sand, dry sand by filling in all round its modelling, finally will be cast into the furnace after high temperature roasting, cast type or shell after roasting, and are casting in pouring molten metal.

Revestment precision casting products for precision, complex, close to the final shape, can not machining or rarely used directly, is a kind of advanced net-shape forming technology, is an excellent technique in foundry industry, its application is very extensive.It is not only applicable to the various types, various kinds of alloy casting, and produce the casting dimension accuracy and surface quality higher than other casting methods, or even other casting method is difficult to cast the complex, high temperature resistant, not easy machining castings, all can use revestment precision casting wrought.

The current world revestment precision casting forming technology has developed rapidly and widely applied, from the current situation, the future is the development trend of this technology in the future of the casting products is more and more close to the components, the traditional casting as a blank, only has not adapt to the market fast strain.The complexity of the components and quality level is higher and higher, development means more and more strong, professional collaboration began to emerge, and the application of CAD, CAM, CAE, become the main components of product development technology.

From the present development situation analysis, the application surface of investment precision casting technology is very wide, the future development prospect wants to be broad.
