1.  Often a large bait in a mold with a short sprue and runner needs more plastic to draw upon as it cools.  A sprue extender expander increases the amount of plastic in the reservoir to the cavity.  
2.  A sprue extender can extend the height of molds so that you can easily inject multiple molds of different heights when clamping them together.  

  • The sprue extenders are machined to 0.630" for a depth of approximately .25 inches to accomodate many standard 5/8 inch (.0625) nominal size hand injecters.   
  • The nipple that fits into your mold is sized at 0.620" so that it should fit into most common hand injection plastisol bait molds. 
  • The nipple reaches approximately .25 inches into your mold sprue.  
  • The overall length is the advertised length plus the length of the nipple that goes into the mold.  ie) a 3 inch extender insert into a 3 inch mold will place the top at 6 inches.  
  • Nominal outside dimension is 3/4 inch (0.75").
  • Internal passage dimension (ID) is 1/2 inch (0.50").
  • The overall external finish is left as the stock came from the mill in order to keep costs down.
  • Other size sprue extenders can be made, but non standard sizes will cost a few dollars more.  
  • Sizes 1-3 inches long are all priced the same as machining is the majority portion of the cost.  Longer sizes cost more as deeper machining takes a couple extra steps.
