Sand casting is a casting method that uses sand as the molding material to manufacture metal castings. It is the most widely used and oldest casting process, highly favored for its low cost and high flexibility (almost any size and complexity of parts can be cast).
Advantage |
|
Low Cost |
The raw material (sand) is cheap and reusable |
Flexible in size |
Castings ranging from a few grams to hundreds of tons in weight can be produced |
ComplexShape |
It is capable of manufacturing parts with complex inner cavities and shapes |
Various Material |
It is applicable to almost all metal materials, especially cast iron, cast aluminum |
Disadvantage |
|
Rough Surface |
The surface quality of the casting is poor, and its dimensional accuracy is not as good as that of precision casting |
Large tolerance |
+-1mm |
Production Efficiency |
Although it can be automated, the production cycle per piece is still relatively long |
Environmental Issue |
Dust and waste gas will be produced |
Many Defects |
It is prone to casting defects such as pores, shrinkage cavities and sand holes |
