casting mould powder with high strength

Casting mould powder: 1. high strength 2.low breaking rate 3.good sphericity 4.reasonable price

Casting mould powder:

Shape	Small round grain
Grain size	0.45-0.90(take up 97%)
Minimum sphericity	0.80
Bulk density	1.50-1.80g/m3
Max Acid solubility	5%
Max Broken rate	8%

Lost foam casting:

Casting material: gray iron, ductile iron;

Usage: filling sand when lost foam casting;

Utilization effect:: improve dimensional accurancy and surface quality.

Casting mould powder 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
