Ceramic foundry sand for resin sand can reduce the cost of raw materials.

The ceramic foundry sand produced by Luoyang Ruiyu has the advantage of small thermal expansion coefficient, and its performance can be comparable to that of zircon sand. The casting will not have expansion defects when the molding sand is prepared with the ceramic foundry sand. Ceramic foundry sand is a neutral material,and both acid and alkali binder can be used with . Ceramic foundry sand also has a special advantage, that is, it is not broken, no dust, can be recycled repeatedly, recycled for hundreds of times, and the cost performance is naturally high.

The Application and Characteristics of Lost Foam Casting

Nowadays, the application field of lost foam casting is wider and wider, and it is a new casting technology with great development prospects. Lost Foam Casting (LFC) is a casting method in which the foam model is used to replace the wooden model, and the liquid metal is poured directly without taking out the foam model, so that the ideal castings can be obtained. Compared with the traditional sand casting, the lost foam casting has great advantages in producing single piece or small batch of cast iron platform, machine bed and other large moulds. It not only saves the expensive cost of wood molding, but also is easy to operate, shortens the production cycle, improves the production efficiency, and has the advantages of high dimensional accuracy, small machining allowance and good surface quality.
