Insulating Sleeves

Riser sleeves are insulating, lightweight riser sleeves used to efficiently feed steel castings. They are highly heat resistant and provide superior insulating characteristics. The use of riser sleeves increases casting yield by allowing smaller riser sizes than conventional sand risers and reduces cleaning costs. Suitable for ferrous and non-ferrous metals (aluminum, bronze, ...)

We have different compositions, exothermic and / or insulating, for each sleeve model. Ask us to know which one best suits your needs.
