Exothermic Sleeves Manufacturer, Supplier in India

Exothermic Sleeves

Extend solidification time and feeding capacity of riser

We are professional exothermic sleeves manufacturer. 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)

Features and Benefits

High calorific value and good heat-insulating property
Good spread ability and good slag coagulation effect
No carburizing and contamination of the molten metal while casting production

Control casting shrinkage porosity & shrinkage defects
Increase overall yield of casting & profitability
Reduce cleaning and repair costs. Reduce casting internal defects

Sleeves have a properly designed taper so as to insert the sleeve into preformed mould cavity. Close dimensional tolerance, high strength and excellent surface finish allow foundry operator to neatly push-fit into the mould cavity.

Features and Benefits

In ram up applications where sleeves are placed on pattern plate prior to moulding in either machine moulding or hand moulding.
In shell moulding
In high pressure moulding machines where pattern plate is accessible but squeezing pressure makes it impossible to place sleeves while moulding and hence calls for insert application.
In automatic moulding lines where pattern plate is not accessible, feeder sleeves have to be essentially inserted after mould is stripped.

Stringent and Eco-friendly Manufacturing Process

At Magna Ferrochem Pvt. Ltd. we follow zero waste generation system and do not allow any effluent or solid disposal. This makes the production system eco-friendly. Stringent quality control is observed during incoming, in process and finished product stage. Sleeves are manufactured under precise control to ensure consistent performance at customers end.
