For the investment casting process used to manufacture mechanical parts such as turbine blades, propeller, engine shell, etc., water-based silica sol binder has high temperature adhesion and environmental protection, and becomes the choice of binder for mold shell manufacturing. With its excellent properties, water-based silica sol gradually replaces the traditional shell-making process of water glass and ethyl silicate.
Our company also provides mold wax, refractory, quartz sand, corundum, zirconium sand, wetting agent and cleaning agent, defoamer, heat preservation agent, slag remover and other casting accessories
