Product introduction
Even though quartz sand is widely distributed and easy to get with low cost; it has obvious shortcomings, for instance, large expansion coefficient, low precision castings, serious sticky to casting surface and difficult to clean the sticking sand.
Kupper fused ceramic foundry sand is made from high quality bauxite and processed by calcination, fuse, granulation and sieving. So fused ceramic sand can overcome these shortcomings and greatly improving the quality of the casting.
