Lost foam casting:

Casting material: gray iron, ductile iron;

Usage: filling sand when lost foam casting;

Utilization effect:: improve dimensional accurancy and surface quality.

Green sand for foundry Advantages:

good fire resistance;spherical particle shape;low thermal expansion rate;good resistance for crushing;can be used as neutral material, PH=7.8, stable chemical properties, acid and alkali resistant erosion, low acid consumption.good compactness and high strength. Even repeated use rarely broken, reduce dust pollution in the production process when casting. Good reproducibility, reduce industry waste discharge and is good for environment protection.small bulk density, reduce production costs;wide usage range
