Analysis of the advantages and disadvantages of sand casting

Sand casting has many advantages:

1. Wide selection of materials. Sand casting can complete the casting of many metal raw materials, such as steel, iron and most non-ferrous alloy materials. As long as it is a metal that can be melted, it can be easily completed using sand casting;

2. Design flexibility. Sand casting can produce castings as small as a few grams or as large as several tons, and the size of the parts can also be adjusted according to the requirements of the castings. Whether it is a simple or complex shape, or something that other casting methods cannot complete, sand casting can solve it, and the casting restrictions are small.

3. Low production cost. Compared with some other casting methods, the molds and equipment used in sand casting are lower in cost and relatively low in price.
Sand casting also has its shortcomings:

1. Low strength and dimensional accuracy. The castings produced by sand casting have low strength and poor dimensional accuracy due to their high porosity;

2. Poor surface finish. In sand casting, casting sand and sand binder are mainly used. If the sand mold is not selected properly, it is easy to cause obvious surface texture of the internal sand mold wall, which seriously affects the surface appearance of the casting.

The above is an analysis of sand casting and its advantages and disadvantages. I hope it can help you!
