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 utilising automatic core shooting machines to make a suitable mixture which will be put in the hot box cores moulding 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 mould within mould.
