Description

What is Sand Casting Process?

Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages.

The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:

No. Steps Details
1 Pattern Creation A two-piece metal pattern is created in the shape of the desired part, typically from iron, aluminum or wooden material.For a single casting or small batches of castings, we prefer to produce to use the wooden material to manufacture the mold to save money for customers.

For other sand casting parts in large quantity, we prefer to use aluminum or iron to improve the mold’s service life.
2 Mold creation The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold. The shell mold is then placed into a flask and supported by a backing material.
3 Pouring The mold is securely clamped together while the molten metal is poured from a ladle into the gating system and fills the mold cavity.
4 Cooling After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final castings.
5 Casting removal After the molten metal has cooled, the mold can be broken and the casting removed. Trimming and cleaning processes are required to remove any excess metal from the feed system and any sand from the mold
6 Machining  Machining as per drawings

Advantages of sand casting process

  • Versatility: Sand casting process can be used to produce a wide range of shapes and sizes, from small & intricate parts to large & sample parts, weight up to 10,000 kgs.
  • Short lead time: Compared with die casting or Investment precision casting process, sand casting has short lead times because of short mold production time.
  • Widely material choice: Almost any metal can be sand mold casted, for example, cast steel, ferrous and non-ferrous cast iron, aluminum and bronze.
  • Low Cost: The sand casting of Baoding Guokun is cost-effective for small-quantity runs, and the molds are inexpensive to make, especially the wooden mold.

Disadvantages of sand casting techniques

The sand casting parts is often with rough surface finish, lower strength, high labor cost (if done manually). And Secondary machining often required.
