Sand Casting

In Sand Casting (“SC”), molten metal enters a sand mold either by means of gravity or low pressure. This technology is generally employed for smaller and mid-sized series components due to the ability to produce finer and more complex structures. There are two types of mold forming processes, including (i) manual molding and (ii) machine molding.

In the manual molding process, the molds are assembled manually, for small to medium volume jobs, and in machine mouldings the assembly is automated. The patterns can be used repeatedly, whereas each mold is destroyed after the solidification to release the cast part. This process is very cost efficient for certain applications and small to medium volume jobs.
