Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.
