About Riser Sleeves
Riser Sleeves are refractory components used in foundry and steel casting to ensure proper feeding of molten metal during solidification. Installed around the riser head, sleeves help compensate for shrinkage and prevent internal defects such as piping and cavities. By maintaining controlled heat retention, they improve casting yield, reduce riser size, and enhance overall productivity.
Exothermic Sleeves
Exothermic Sleeves are high-performance riser sleeves used in steel and iron casting to enhance feeding efficiency during solidification.
Insulating Sleeves
Insulating Sleeves are high-performance riser sleeves used in steel casting and iron foundry applications to improve feeding efficiency during solidification.
