304L stainless casting flange
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. First, make wax molds (fired molds) with fusible paraffin and stearic acid. And then coat the wax molds with silica sol zircon sands and refractory powder to make mud molds. Dry the mud molds out and put them into hot water to melt the wax molds inside. When the wax molds inside are completely melted, take them out, fire them into ceramic molds and silica sol investment molds are manufactured. When the ceramic molds are fired, a sprue gate must be reserved to allow molten metal flow in. Cool the molten metal down and castings are produced.
Features
This technique is mainly used to produce carbon steel and stainless steel castings. These castings generally have the following features:
