Shell Cores

Eskay Industries are able to produce quality Shell Cores .Shell cores are made by blowing resin-impregnated sand into a heated metal core box. The resin hardens when heated up to a given temperature meaning that any sand that comes into contact with the hot surfaces of the core box will harden. Sand within the centre of the core is insulated by that of the sand surrounding it, which is then free to fall out leaving a hollow shell hence the term 'Shell Core'.
