Sand Core Making Process

In this phase silica sand (having specific characteristics) is mixed with some chemical products, as resins and catalyzers and dried by plates electrically heated at 300ºC using automatic core shooting machines to make a suitable mixture which will be put in the hot box cores molding machine. . This machine, by means of the so called “HOT CHAMBER” process, produces the cores necessary to the next phase, the Casting. Cores play an integral role in casting technology and are used to make water channels within the products. It is more like replacing / forming mold within mould.
