Sand Molding Approach

Sand mold casting is the best-value mold method for this component based on the casting requirements and the production factors.  
Two types of sand molding can be considered.

  • Green Sand Molding 
    Moist, clay-bonded sand is tightly packed around  wood or metal patterns in mold boxes. The pattern halves are removed, and the  two mold halves are assembled with or without cores.   

    • The term "green" denotes the presence of moisture in the molding sand, and indicates that the mold is not baked or dried. 

  • No Bake Sand Molding
    Sand is again packed tightly around a wood or metal pattern, but the sand is bonded with a self-setting organic binder. The bonded sand has higher strength and improved dimensional control, compared to green sand.
