Features. Adaptive Tooling. Muller wheels are mounted on independent, spring-loaded suspensions. As the molding sand mixture increases in volume and strength, the mullers react by raising and increasing the mulling pressure. This is a versatile and inexpensive source of mixing energy which provides the kneading and compression action of mulling.

Sand Casting: The sand casting process also called as sand mold casting. It is a common method for metal casting. Almost 70% of metal casting of product follow by sand casting process. The bonding agent (clay) is mixed with the sand. The mixture is moisturized with water for develop strength and plasticity of clay to make mold.
sand casting processes are a limitation to this technique. Many new casting processes have been developed which can take into consideration the aspects of dimensional accuracy and surface finish. Some of these processes are die casting process, investment casting process, vacuum-sealed moulding process, and shell moulding process.
The pattern is made out of wax, wood, plastic, or metal. The molds are constructed by several different processes dependent upon the type of foundry, metal to be poured, quantity of parts to be produced, size of the casting, and complexity of the casting. These mold processes include: Sand casting Green or resin bonded sand mold.
In green sand clay bonded, process the sand is used over and over again after some treatment of the used demoulded return sand.
