Sprue Cutoff Tool for Molded FCC Plugs 
The sprue cutoff tool speeds the removal of 
sprues from FCC plugs after molding. The four 
sprue contact points (injection gates) are severed by 
two offset blades that are attached to a handle-
actuated cam. The blades can be adjusted horizon-
tally to accommodate sprue removal from plugs that 
are from Ito 3 in. wide. 
The sprue removal operation is accomplished by 
positioning the plug on the tool bed, adjusting 
the blades, and moving the handle down for the 
cutting process. The blades are raised to remove 
the trimmed plug.
