Introduction
Water glass investment casting is a common casting method. Its process is as follows: add water glass to the modeling material (usually silica sand) in a certain proportion, stir, roll, and mix for 6-8 minutes to make "water glass sand" and put it into the mold. The carbon dioxide gas is blown into the sandbox, and the CO2 reacts with the water glass to form silica gel, which hardens the water glass sand. The pouring process is completed by demoulding, closing the box and pouring. This method is suitable for carbon and alloy steel castings because it minimizes the mechanical loss of the material during processing. We are able to provide high quality water glass investment casting, which not only has few casting defects, but also provides excellent dimensional accuracy and smooth surface for the finished product. This casting method is an ideal solution to reduce production costs and increase production efficiency.
