Blind Riser Sleeves

Sleeves are produced with a normal wall 1/2” thick. The following riser sizes are available. Special sizes can be made on request.

Hot Topping Compounds

Hot Toppings features a unique combination of insulating and exothermic characteristics for improved feeding of castings. They are available for both ferrous and non-ferrous applications. Foundries are able to reduce production costs due to the topping compounds ability to:

· Reduces riser heat loss to atmosphere

· Maintain open riser to assure continued feeding

· Reduce piping in risers

· Assure integrity of the casting

· Increase metal yield

· Easy to apply

Hot Toppings available in five gallon pails, fiber drums and bulk bags.

Filters

T1- economical filter for use in aluminum and magnesium casting

T2- durable filter for use in copper base and iron casting

A wide assortment of standard squares, rectangles, discs and 22 1/2 degree tapered discs are readily available.
