Sand preparation is the essential key factor towards getting a consistently hard mold with smooth surface finish, ensuring that the permeability allows the mold to breathe. It is extremely essential that the sand preparation is completely automated. SLC has installed a Sand Plant from EIRICH which is operated using a SCADA based PLC, thereby reducing manpower intervention to a large extent. The sand preparation plants have PLC controlled systems and prepare moulding sand by a fully automated process in order to get high surface quality.
The EIRICH intensive mixer produces 40 MT of sand per hour and matches the molding line requirements in terms of molds per hour. The high level of automation permits us to operate the sand plant with a skeletal manpower, thereby optimizing process costs.
