Insulating exothermic sleeves designed for riser and feeding of cast iron and steel parts. They combine controlled exothermic reaction with insulating materials to maintain local temperature during solidification, reducing typical defects such as porosity or unwanted reactions between molten metal
High-performance exothermic and insulating sleeves designed for feeding (feeding) of cast parts in iron, steel, and their alloys. These sleeves combine exothermic function and thermal insulation to maintain the feeding of the feeder/riser, promoting directed solidification and reducing defects such
