Introduction to Molding Process

Green Sand process has a long history. However, to discuss its early state would entail research work of archaeological field. It is important for foundrymen to discuss the development of green sand process on the 20th century.

In this century, green sand process become the main molding process instead of dry sand process. This is due to various technological developments on foundry.

Green sand process was used in many foundries and contributed to the development of the foundry industry. Now a days several new sand molding process had been considered which consequently reduced the use of green sand process.

However, the foundry for the purpose of producing small and medium size castings are still using the most important molding process, green sand.

While conventional molding process using natural sand is also worth to remember, modern molding process using synthetic green sand is better to focus on.
