Introduction of Ceramsite(foundry sand)for Metal Foundry

Ceramsite(foundry sand) can be widely applied to the production of medium and small castings of cast iron casting carbon steel casting medium and low alloy steel stainless steel and nonferrous alloys.

The dimensional accuracy of the casting can reach to class CT6-CT7 and surface roughness can reach Ra12.5m by using the shell casting technology of Ceramsite(foundry sand), which greatly improves the quality of the casting.

The advantages of Ceramsite(foundry sand)for Metal Foundry

1. The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

2. The surface is smooth and the structure is compact, so that the binder can cover evenly.

3. Good recycling performance and high cost performance

4. High thermal conductivity, good stability, no cracking

FAQ

Q1: How do you ensure the quality of the product?
A: Top Chemical have a very complete quality management system, from the control of raw materials to the factory inspection of finished products. We regularly provide samples to third-party testing organizations for testing.

Q2: How long is your delivery time?

A: We have 8 fully automatic production lines and can guarantee around it’ll use 15 days from the customer's order to delivery.

Q3: What are the advantages of ceramsite(foundry sand)?

A: The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

Q4: What are the advantages of ceramsite(foundry sand)?

A: High fire resistance, easy to collapse. The mullite phase of ceramsite(foundry sand) is much higher than that of sintered product.

Q5: What are the advantages of ceramsite(foundry sand)?

A: High thermal conductivity, good stability, no cracking

Q6: Why you should choose ceramsite(foundry sand)?

A: The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

Q7: What the ceramsite(foundry sand) become more and more popular?

A: High fire resistance, easy to collapse. The mullite phase of ceramsite(foundry sand) is much higher than that of sintered product.
