Silica sol precision casting is a type of precision casting that produces high-quality products, which have been widely used in industrial production. Silica sol precision casting has good stability function, and its product has a wider pH range and a longer stable storage time. Silica sol precision casting requires less protection during storage, which can adapt to high shear stress mixing, The inter layer drying time of the product is further shortened, but they suggest that this enhanced silica sol can shorten the inter layer drying time to 1 hour.
Silica sol precision casting has strict requirements for the shell making environment and wind speed. For castings with slender pores, the dry time between layers needs to be appropriately extended. High polymer additives can better help reduce the shortcomings of the shell and castings. The effect of additives in silica sol precision casting during the manufacturing process will no longer be limited to helping the shell quickly establish wet strength, The direction of improving the quality of investment casting will also be useful together. The surface quality of the silica sol shell is good, and its high-temperature strength is high. The high-temperature deformation resistance of silica sol precision casting is strong, and the product requires a process with high precision. In practice and theory, it is necessary to strengthen the knowledge of precision casting technology, continuously make up for professional tests, and enrich its practical experience.
When using silica sol precision casting, during the filling process, the foam model needs to be liquefied and differentiated, and its products will produce many small molecules of gas and foam ash. At that time, these substances were harmful to the human body, and operators had to strictly follow their operating manuals in daily work.
