Investment casting sand Al2O3 based ceramsite sand AFS45

 Production Introduction:

Investment casting sand Al2O3 based ceramsite sand AFS45

Ceramic sand ( ceramsite sand)is an advanced substitute for quartz sand in the casting field. Ceramic sand is made from calcined bauxite with the main content of aluminum oxide processed by melting, blowing, sieving and blending. After melting calcined bauxite with 65-90% aluminum oxide in a high-temperature electric arc melting device, the outflow of ceramic is blown into fine particles. Then after cooling and sieving, the ceramic sand becomes finished particles with different size grade.

Characters:

1.       Low thermal expansion coefficient

2.       High strength with good compressive strength and bending resistance ability and low broke rate.

3.       spherical shape, good flowability, easy to shakeout

4.       smooth surface, compact structure

5.       chemically neutral material

6. high-temperature resistance, good refractoriness

7.       Recycle up to 10 times, highly cost-effective.

8.       Save resin consumption with casting tech such as shell molding, Resin coated sand casting, Vacuum casting, etc.

Applications:

1.    Shell molding

2.    Precision Casting

3.    Lost foam casting

4.    Heavy steel casting

5.    Resin coated sand casting

6.    Vacuum casting

7.    Investment casting
