Silica Sol Investment Casting for Precision Casting

Silica Sol Investment Casting for Precision Casting

Silica sol investment casting, as its name implies, is a casting technique that adopts silica sol investment molds for casting manufacturing. Silica sol investment mold is a kind of casting mold that takes silica sol zircon sand as molding materials.

Features

This technique is mainly used to produce carbon steel and stainless steel castings. These castings generally have the following features:

Excellent corrosion resistance performance and great dimensional accuracy.

Better surface finish and smaller geometric dimension deviation.

Widely used as auto parts, pipe parts, valve parts, pump parts, ship hardware furniture decorative parts, etc.
