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.

How long does sand casting take? This is a question that many customers will be curious about at the beginning. In fact, the cycle of sand casting is affected by many factors, such as the size of the casting, the complexity of the shape, the mold preparation time, and the subsequent cleaning and processing procedures.

When it comes to metal casting, many people will immediately think of those high-end automated production lines and sophisticated processing equipment. But do you know? To this day, sand casting still occupies an irreplaceable position in various manufacturing industries.

Many people will consider the choice of casting process when developing parts or supporting mechanical equipment. People often ask us: "Is sand casting cheap?" The answer is of course - very cheap! It is one of the most economical and practical casting processes in the industry.
