Pattern Making

Shell cores are made using a resin coated silica sand that is blown into an iron corebox. The corebox is preheated to about 550 degrees fahrenheit and the core(s) cure and become rigid due to the reaction between the resin and heat. The hollow shell that forms the core gives it its name. Shell cores provide the best cosmetics and dimensional tolerance of all the core processes.
We can make shell cores with production runs from prototype to 50,000 and over.
