Thermal and Insulating Shirts

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 as porosity or unwanted reactions between the metal and the mold.

Main Features

• Thermal performance: combination of exothermic material and insulating layer that maintains heat in the feeder to prolong feeding during solidification.
• Compatibility with multiple alloys: suitable for steel (carbon, high and low alloy, stainless, Hadfield) and different types of iron (malleable, nodular, grey, various alloys).
• Suitable for various types of sand casting: manual molding, pressure and shake molding, blow molding, shot blasting, and explosive blow molding.
• Improvement in part quality: reduces porosity, prevents metal-mold reactions, and promotes sound parts with less rework.
• Shapes and adaptability: available in different diameters and heights to fit cylindrical feeders and other geometries; standard or custom solutions can be provided.

Benefits for casting

• Increased feeder performance and better control of solidification.
• Lower rate of rejected parts due to internal defects (such as porosity or reaction inclusions).
• Reduction in metal consumption and optimization of riser design by improving feeding efficiency.
• Operational flexibility: use on different production lines and molding methods.
