Sand Casting

The cast molding process is basic, create a cavity in the shape of your desired part and then pour molten metal into it. Sand casting, also known as sand molded casting, is a metal casting process that uses sand (called casting sand) as the casting material.

After centuries of development, sand casting is the most versatile and arguably the most widely used metal casting method. Design requirements (including shape and size requirements), workpiece and mold costs, required quantities, and even manufacturing feasibility determine which metalworking process (including which casting process) is most suitable.

Products manufactured using sand casting employ techniques that can produce formed parts of almost any design, including very large parts and parts with internal channels.

The Sand Casting Process Steps:

● Producing The Pattern – Desired Product
B. Producing The Pattern – Gates And Risers: The Metal Delivery System
C. Creating The Mold
D. Pouring The Metal Into The Mold
E. Shakeout
The casting, including both the desired part and the additional metal needed to create it, solidifies and cools. The sand is broken way in a shakeout process.
Much of the sand used to create the mold is captured, reconditioned, and reused
F. Final Operations
The gates, runners, and risers are cut from the casting, and if necessary, final post-processing sandblasting, grinding, etc., are performed to finish the casting dimensionally. Sand castings often require at least some additional machining to reach final dimensions or tolerances.
