SEFU Exothermic Sleeve Application
The exothermic sleeve is mainly suitable for clay sand molding lines, self-hardening sand, and shell mold process. It has a good feeding effect on non-ferrous alloys (aluminum, copper), cast iron, and steel castings.
SEFU Exothermic Sleeve Function
Exothermic riser sleeves are planned to offer effective feeding of metals by extending the solidification time of risers used on steel and other castings.
The riser sleeve has high strength and can be embedded in the mold on the board or embedding the sand mold after modeling, it is accessible for on-site workers to design and save modeling time. It can extremely enhance the yield of the casting process. It has excellent heat generation.
Breaker Cores
SEFU exothermic riser sleeves can be equipped with breaker cores according to your needs. The exothermic sleeve with breaker cores integrates the functions of easy cutting, heat preservation, and heating. The unique chip breaking core design can greatly reduce the cutting and grinding area of the heating sleeve and reduce the cleaning cost.
