Blind Risers

Blind riser sleeves are placed in the mold to allow the casting to be fed during the pouring process. Spherical and dome shape blind riser sleeves can increase yield by reducing the metal weight of the riser by as much as 30% compared to cylindrical shapes. Spherical blind risers are available from 1.5” to 24” inside diameters and have built-in firecracker cores, and 50% reduced contacts. The domes are available from 0.75” to 14” inside diameter.
