Shooting a 5.5 fat beside bears 6 inch stick. The 6 inch sticks come out like a dream, the 5.5s on the other hand, are bothersome. In the time I made 25 regular sticks, I only made 6 fats. Almost all the 5.5s have air pockets. I've tried letting the plastic cool, pour it hot, and can't seem to get them right. Using baitjunkys plastic too by the way. Thanks guys

When I open pour sticks I use a spru extender.  Not the ones that cost about $5 each though.  I bought copper couplers in the plumbing section of Lowe's that are larger then the hole and about 1" long.  I set them over the holes and pour until they are full.  That gives me plenty of extra plastisol to accommodate any shrinkage.

 

 

Yup. Gotta keep the sprue filled at all times. Big sticks shrink alot and draw alot of extra plastic.

Well maby that's our problem, I been using a couple "El Cheapo" 11/16 sockets, but the copper coupling is an awesome idea

Here's what I mean guys, dimples in the plastic, pouring super slow, and using an old socket as a resivore for more plastic to stay supplied so I don't have to top off

Sorry guys, having trouble uploading

That looks like a cooling shrinkage problem to me.  Try the copper fittings and maybe a few degrees hotter plastisol.

Mold should suck a good amount of plastic as it cools. The gate (skinny part at head of bait where you remove it from the sprue) might be too small or coling too fast (cloggig) and not allowing more plastic to be sucked in.

 

I assume baits are horizontal and not vertical

 

Plastc around 330*

Purge air out of injector

Inject slow and steady. 5 count.

Hold firm pressure 10-15 secs.

Remove inj and top off imediately

Retop off every 10 secs till it stops sucking in.

 

If this does not work, something is wrong with the mold or mold design.

I have the exact problem with the exact mold, it seems like when i dont salt i dont have the problem though..

In all honesty, I starting putting more salt in and it helped the problem

Are baits vertical (up and down) or horizontal in that mold?
