What is Silica Sol Investment Casting?

Silica sol investment casting is a casting process that utilizes silica sol (a silica-based solution) as the binding material to create casting molds. This method yields metal castings with exceptionally smooth surfaces and high precision, typically achieving dimensional tolerances ranging from CT4 to CT6. Silica sol casting is the primary investment casting process employed by RMC for the production of stainless steel and alloy steel castings.

Applications of Silica Sol Casting

Silica sol casting is primarily employed in precision casting. While it entails a relatively higher production cost, it delivers finely precise dimensions, exceptional surface finish, and an overall high level of quality. If you are seeking a manufacturing method for small components that require precision, demand superior surface quality, possess high corrosion resistance, and wish to avoid the gradual quality improvements associated with other casting techniques, Silica Sol Investment Casting should unquestionably be included in your list of options.
