Hollow spots in senkos

Recommended Posts

Several things can cause it. Let’s make sure we understand hollow spots. Is it a dent or like a large air bubble?

Not holding pressure on it long enough is one thing.  Temp is another.  I have to shoot my sticks at 315 degrees and hold a 10 count.

I would say shoot slow. Not a lot of appendages you need to fill fast on a Senko and shooting fast will sometimes cause some void type issues. As J.Burch said, 310-320 on the temps.as too hot will cause dents. Need enough good hot plastic to fill the mold as anything questionable in terms of volume will cause issues. Be sure and top the mold off as it cools. Some molds with small runners may require this. Let us know how it goes and good luck.
