Smart Engineering exothermic sleeves  is a mixture of exothermic and insulating  materials and are designed for different kinds of cast iron, steel and other metals.

Smart Engineering exothermic sleeves increase performance heat occupying  30-35% of the normal sleeve without exothermic effect. This property is very valuable for the small type foundries, allowing them to avoid the additional cost.

Smart Engineering exothermic sleeves  provide  error-free and more quality casting, minimizing cavities within castings,as well as the possibility of shell cores can significantly reduce the cost of machining.
