Many people who don't know much about the foundry industry should have been curious about what kind of "sand" sand casting uses?

When many people learn about casting technology, they often ask: "Is sand casting precision high?" This question is very practical.

In fact, the biggest advantage of sand casting is flexibility, low cost and wide adaptability.

When it comes to sand casting, many people will be curious: What is the minimum wall thickness of sand casting? Generally speaking, the minimum wall thickness of sand casting is about 5 mm. If the wall is too thin, the liquid metal is prone to insufficient filling, pores, cracks and other problems during pouring and cooling, so 5 mm is a more reasonable and safe design reference.

​When many people hear sand casting for the first time, they will think that it is not strong enough because of the word "sand". In fact, on the contrary, the sand mold is only a mold material used to form the shape of the casting, and the final shape is high-temperature molten metal, such as cast iron, carbon steel, stainless steel, etc.

In the GCSE course, sand casting is a very classic metal manufacturing process. Simply put, sand casting is to first make a casting mold with sand, pour the molten metal into it, wait for it to cool and solidify, knock off the sand, and a complete metal part is born.
