The machining process and technical application of silica sol precision casting

Silica sol precision casting has excellent stability in its solution during use, with a wider pH range for product value adaptation and longer stable storage time. Silica sol precision casting requires less maintenance during storage and can adapt to high shear stress stirring.

The interlayer drying time of silica sol precision casting is further shortened, but it can be effectively reduced to 1 hour to enhance the interlayer drying time of silica sol. The shell making environment, especially the wind speed, has very strict requirements. For castings with slender pores, the interlayer drying time can be appropriately extended.

The surface quality of silica sol precision casting is good, the high-temperature strength of the product is high, its thermal shock stability performance is good, and its high-temperature deformation resistance is strong. Silica sol precision casting is an advanced casting process technology with few or no cutting in the casting industry.

Silicon sol precision casting is not only suitable for casting various types and alloys, but also for producing castings with higher dimensional accuracy and surface quality than other casting methods. It is even more complex and heat-resistant than other casting methods.

The size of the silica sol precision casting itself is not very large, and the product does not require high precision. Aluminum frame tin bismuth can be considered as a mold. Tin bismuth molds are relatively heavy, mainly because they contain bismuth. However, for complex molds, the production time is short and the cost of machining is saved.
