Lost Wax Cast Steel
Investment casting, also known as lost wax casting, is a fusible model (referred to as a melting mold or a model) made of a fusible material (such as wax or plastic), on which several layers of special refractory coatings are applied. After drying and hardening to form a monolithic shell, the model is melted from the shell with steam or hot water, then the shell is placed in a sand box, filled with dry sand molding around it, and finally the mold is placed in the roaster The high temperature baking is carried out (for example, when the high-strength type shell is used, the mold shell after demolding can be directly calcined without molding), and the mold or the shell is fired, and molten metal is poured therein to obtain a casting. The products obtained by investment casting are precise and complex, close to the final shape of the part, and can be used directly without machining or processing. It is an advanced process of near-net shape formation and an excellent process technology in the foundry industry.
The application is very extensive. It is not only suitable for the casting of various types and various alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods, and even castings that are difficult to cast by other casting methods, which are difficult to mold, are not easy to process. Can be cast by investment casting.
We have full set of quality control system to guarantee best product quality. Depends on the products, we make different item testing plan, different manufacturing procedure and provide certified lab mechanical testing.
We have the chemical analyzing chamber to analyze the component content of the material after entrance to the factory, on melting and after casting to promise the chemical component content.
After getting the drawing , we first put into the software anycasting to analyze and build the mold and the feed system.
Also we can do the strength test for mechanical stress.
Any way we can supply our costumer the qualified product, as promised.
