What is Sand Casting

Sand casting, known as sand molding casting, is a casting process that uses sand as a mold. Then pour the liquid metal into this mold to create a casting part.It is one of the oldest casting processes. It can be used to make metal components of all sizes, ranging from 1kg to hundred tons. The statistics show more than 61% of all metal castings are produced by sand casting.

In modern industry, the sand casting Process controls, material options, tolerance capabilities, the ability to produce elaborate parts, broad size ranges have all come a very long way. It has several unique advantages.
 

The advantages of sand casting

• Suitable for more metals types.
• Can be for large size, Complex shapes sand casting products
• Compare with other metal forming processes, Tooling and equipment cost is low
• Scrap metal can be recycled
• Short lead time
