Exothermic Sleeves (Range of exothermic cum insulating sleeves)

We are a professional Exothermic Sleeves Manufacturers in India. Exothermic riser sleeve can be used as riser topping for iron and steel castings, extending solidification time and extending feeding capacity of riser

MAGNA EXOTHEREMIC SLEEVES are superior quality exothermic cum insulating in nature and are suitable for Iron and Steel castings. Raw materials carefully selected and used for manufacture of sleeves result in a bulk density of 0.55-0.58 g/cm3.

This ensures excellent insulating properties in post exothermic stage. Exothermic material burns and generates temperatures more than 1500 °C. As a result, these extend solidification time of the metal inside the sleeve by a factor of about 2.5 as against sand feeder of the similar size. The Modulus Extension Factor (MEF) for these is in the range of 1.4 to 1.8 (MEF is more for smaller sleeves)
