Silica Sol Investment Casting

Silica Sol Investment Casting

Silica sol is a kind of milky colloid, which is mutually soluble with water , but not with organic solvent. Silica sol casting components are mainly used for products with requirement of high corrosion resistance and precision dimensions, since silica sol steel castings can have much better surface quality and less geometrical deviation of dimensions. Silica sol investment castings have very good surface,very smooth and very less surface and inside defects. The main silica sol castings we ever made include stainless steel material, carbon steel material, such as  valve castings, pump castings, marine hardware, furniture decoration and other industries.

Silica Sol Casting Process in our factory

Silica sol castings mainly have four major steps: wax making, shell making, casting and post-processing. Once these four major processes are completed, the casting blank can meet the basic needs of customers. The subsequent processing can be carried out  such as surface treatment, cnc machining according to customers requirement. Please be understood that these four major steps can be divided into more than 20 sub-processes, that’s why silica sol casting process needs time to finish the production.
