The Common Sand Varieties Used By Sand Casting Manufacturers

Though there are various methods through which you can produce non-ferrous alloy casts, one which is widely preferred by sand casting manufacturers is sand casting. They can be produced in various weights according to your requirements. This traditional process has undergone many changes in the last few decades which has modernised the process but its basic principals are still the same. They use various types of sands during the casting process so that the alloy casts are exactly the way you want.

Approaching Sand Casting Manufacturers? 3 Common Sand Varieties They Generally Use

• Green Sand

When wet sand is used to form the sand moulds, the sand is known as green sand or clay. Before metal is poured into the sand mold, it is in an incurred state. One of the main reasons why this sand variety is widely preferred by the casting manufacturers is because they are inexpensive and quick. They can even reuse the sand in the future. The only disadvantage is that the sand mold produced is a bit soft in nature which can make the structure shift or collapse while the casting is being done and makes them unusable. Inspite of this, green sand is still preferred by many phosphor bronze casting manufacturers and has survived for years.

• Water Glass

Water glass or sodium silicate is widely used for creating mold casting as manufacturers can easily transform them from a liquid state to solid by making the sand pass through carbon dioxide during the casting process. Sodium Silicate gets dehydrated and so manufacturers can easily create a cavity inside the casting. If they want the core to be hard, all they need to do is mix the casting with some other material. This helps aluminium gravity die casting manufacturers to remove the core after breaking down the casting. They leave no stone unturned in ensuring that the materials are mixed in correct proportions which prevent the core from becoming lodged inside the casting.

• Resin Sand

One of the primary reasons why a majority of the sand casting manufacturers prefer using resin sand during the casting process is because once you mix and heat the sand, the solid mold created has a very smooth surface. They don’t have to worry about defective castings. The only disadvantage is that the rate of production is quite slow as they need more time to burn and mix the resin sand and get the perfect molds. Sometimes, the production cost can also increase as resin can be reused by replenishing them continuously.

Approach The Right Sand Casting Manufacturers

If you are confused about which sand variety will suit your casting requirements the best, just approach the right sand casting manufacturer and they will suggest the best product for you. Their focus is on enhancing the plasticity and strength of the clay so that they can be used to form complicated metal parts with ease. With the right casting manufacturer by your side, you don’t have to worry about the ideal sand variety.
