Feeder Long
Optimal alloy fluidics resulting in smooth precision castings.


Product Overview:

Used for direct or indirect casting, the special flow dynamic design promotes optimum alloy fluidics resulting in high quality
castings with perfect fit and accurate margins.

The unique tip creates a “nozzle" effect when casting, eliminating suck-back and controlling porosity.

Stem can be clipped to desired length to accommodate occlusal curvature when investing long span bridges. Great for smaller lighter copings.


Key Benefits:

  • Flow dynamic design
  • Creates a "nozzle effect." Eliminates suck-back.
