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. |
