The method of sand casting has been in use for a long time now. You would be amazed to know that the same was invented around 6000 years ago. Long back when there was no machinery and no technology, people used to use different sands for the purpose of sand casting. From small DIY projects, today sand casting manufacturers are ruling the world.

With modernisation, things have changed. The process of sand casting has become more flexible. The cost of engaging in the sand casting process has also lessened. However, there’s only a slight difference in the process that is being used by different sand casting manufacturers.

The basic difference lies in the type of sands that are being used for the purpose of casting.

What types of  Sand are used for Sand Casting?

The selection of the sand for the casting purpose is necessary because this is the major thing that reduces the expenses. If you’re a buyer of sand, then it’s necessary that before engaging in any kind of casting process, get hold of the prices and be a little knowledgeable about the same.

Green Sand

If you’re in for a low budget sand casting, ask your manufacturer to use the green sand. Quick, less costly and reusable – these are the three basic features of green sand. In layman’s term, it is also known as clay. However, few things you have to keep in mind while using green sand. Since it contains clay, hence it is soft and can collapse while the casting is being done. Keeping all things apart, it is quite a popular process. The majority of the sand casting manufacturers prefer using this method to cast. Every method has its own set of flaws.

Sodium Silicate

Using this version of sand allows the casting to go from liquid to solid form by passing carbon dioxide easily. But it is a difficult casting method. If the mixture is not prepared successfully, then the casting will become useless. It is costlier than the other versions because sodium silicate needs to be mixed with other materials in order to get the core casting done. So the cost is high!

Resin Sand

Sand casting manufacturers love using resin sand. Once you heat the same the sand becomes solid and the surface becomes smooth. But with good things come the bad ones. Using resin sand can be expensive and the production rate will slow down. However, it’s the love of all manufacturers. In case you have a high budget then using resin will be effective for you.
