high quality molding sand

high quality molding sand
Product Detailed
Molding sand: 1. high strength 2.low breaking rate 3.good sphericity 4.reasonable price

Molding sand:


Small round grain

Grain size

0.45-0.90(take up 97%)

Minimum sphericity


Bulk density


Max Acid solubility


Max Broken rate


Lost foam casting:

Casting material: gray iron, ductile iron;

Usage: filling sand when lost foam casting;

Utilization effect:: improve dimensional accurancy and surface quality.

Molding sand 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
