Precision casting has broad prospects for development

2022-03-19

investment casting refers to a fusible model made of fusible materials, coated with several layers of special refractory coatings, dried and hardened to form an integral shell, and then steam or hot water is used to remove the mold from the shell. Melt out the model, then put the mold shell in the sand box, fill it with dry sand molding around it, and finally put the mold into the roasting furnace for high temperature roasting, after the casting mold or shell is roasted, pour molten metal in it Get castings.

The products obtained by investment casting are precise and complex, close to the final shape of the parts, and can be used directly without processing or with little processing. The application is very wide. It is not only suitable for casting of various types and alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods, and even complex, high temperature resistant and difficult to process castings that are difficult to be cast by other casting methods. All can be cast by investment casting.

From the analysis of the development situation, the application of investment casting technology is very extensive, and its future development prospects are expected to be broad.
