Silicon sol precision casting is not only suitable for casting various types and alloys, but also produces castings with much higher dimensional accuracy and surface quality than other casting methods. Even if it is difficult to cast castings through other casting methods, the process is complex, difficult, and resistant to high temperatures.

If we want to produce products with relatively simple shapes, small sizes, and high dimensional accuracy requirements, we can first choose profiles or use cast steel for processing. The advantage of using steel molds is that the materials are cheap, but the disadvantage is that the molds are heavy and require certain processing tools. Some manual operations are quite difficult. Such as complex shapes, high precision requirements, product dimensions, etc.

Further shortened the interlayer drying time of precision casting silica sol, but in order to improve the interlayer drying time of silica sol, it can be effectively shortened to 1 hour. The shell making environment, especially wind speed, has very strict requirements. For castings with elongated holes, the interlayer drying time can be appropriately extended.

Silicon sol precision casting has good surface quality, high-temperature strength, good thermal shock stability, and high-temperature deformation resistance. Silica sol precision casting is a casting process with little or no cutting. These products are advanced casting technologies in the casting industry.

The size of silica sol precision casting is not very large, and the accuracy requirements are not very high. However, tin bismuth aluminum frames can be seen as a mold during use, and the weight of this mold is relatively heavy, mainly because it contains bismuth.

For complex silica sol precision casting molds, the manufacturing time is relatively short, which to some extent saves processing costs. For complex thin-walled castings, ventilation openings can be provided where possible to effectively improve the breathability of the product casing.

Silicon sol precision casting can be equipped with a reasonable pouring system to effectively prevent the interception of air in the casting, which is more conducive to the discharge of air in the mold cavity. During the production process, the pouring temperature can be appropriately increased to minimize the distance between the casting nozzles and the casting cup.
