Modern investment casting precision products require increasingly high dimensional accuracy and surface roughness of castings. Controlling the quality of coatings is one of the effective ways to improve the quality of castings. The shell made with silica sol adhesive has many advantages in terms of process, and the coating preparation is simple

The complex shape of hardware castings is dominated by silica sol casting in terms of process. The complexity of silica sol casting can be analyzed from the control and use of consumables. Its production shape is complex, and the fastening requirements are too high. Therefore, it is necessary to carry out related processing, such as sorting small parts and turbine engine blades, and the proportion and performance of precision casting coatings can be obtained from the manufacturing process. The precision and surface smoothness can be improved according to the required size of the investment mold and the medium-sized cavity used to form the refractory form.

Firstly, analyze the size and surface smoothness of the investment mold itself, evaluate its performance and potential, and then provide a brief overview of the manufacturing process for the shell. In terms of the main products used, silica sol casting is a part of its castings, and we welcome friends to come and observe.
