Casting process Advanced and rigorous

Every operation link is monitored and inspected to ensure the quality of the factory

Good air permeability After the high-temperature molten metal is poured into the mold, the mold is filled with a large amount of gas, which must be smoothly discharged from the mold. The performance of the sand that allows gas to pass through is called gas permeability.

High product strength The ability of sand to resist damage by external forces is called strength. The molding sand must have high enough strength to not cause collapse in the process of modeling, handling, and closing.

Good fire resistance The high-temperature molten metal has a strong thermal effect on the mold after being poured, so the molding sand must have the ability to resist the high-temperature thermal effect, that is, fire resistance. The more SiO2 content in the molding sand, the larger the molding sand particles and the better the fire resistance

Good product plasticity The molding sand is deformed under the action of external force, and the ability to completely maintain the existing shape after the external force is removed. Good plasticity of modeling materials.
