ALFISO Insulating Sprue

ALFISO insulating sprues are made from ceramic fiber, used in lost foam casting,  for pouring iron, steel, or aluminum to the lost foam polystyrene pattern. The thin wall thickness and straight sprue minimizes metal left in the cone after casting, and reduce turbulence and pour times.

The sprues are available with location for filters for direct pouring which eliminates unnecessary running system.

Advantages

Cleaner sand
Very clean surface preventing fibrous inclusion
 Well Fit to the foam buttons
Higher quality casting
