[Predator Bass Baits]

Hey Guy's I got my pressure pot fired up today, ( I will post pics soon )
Anyway I had to use it.
I have 10 molds that are 5 1/4" 4 pours.
After 200 baits the molds were getting hot and then my worms would not pour right. the top 3/4 to 1" would get a void or loose spot, it was not from trapping air, I kept trying and the next 125 baits everyone of them had them so I had to quit, , sure wish I would have quit before that many.
Is it possible the molds are just to hot ?
They did not seem that hot as I have run 100 baits with my presto pot with no problems and those molds seemed hotter ?
Or could it have been the plastic was to cold ?

Any help would be great.

Its caused by shrinking plastic and or the salt settling, stick bait molds ( no matter who;'s they are)were not designed for pressure pots, if your using any pressure I would turn it off and let it free flow

Del, pressure is barely on, pours just like my presto pot did.
and the first 200 baits turned out fine, it was just after I hit 200 baits, and I never stopped in between.

The only possible way for that to happen would be not keeping the top always filled or covering that hole

the hotter the plastic the more it shrinks

Thanks Del but I know it is not from keeping it full.

I don't think your molds are too hot. I have poured tons of sticks with one mold, to the point I needed leather gloves to hold the mold. If my math is correct you only used each of those molds 5 times, should handle that no problem.

Are you injecting them or just doing a pour?
How much plastic did you start with?
Did you have problems towards the end of plastic getting low?
After problem starts did you try and shut pressure off to see if anything changed?

I tried again and the Exact samething just happened.
I am going to play with temps on the plastic. One bad thing is I do not know the temps of the plastic. I need to find a way to get a probe sealed inside the pot.
I did remove the lid a couple times and zapped the plastic with a raytec gun and plastic was 335 deg. so I turned the pot up and ended up burning a half gallon of plastic zap gun said it was 365 when it burnt.

Could it be that the plastic level is too low after 200 baits? If it is happening at the same point more than once and (as jmik said you've only used each mold 5 times) I'd have to think that it has nothing to do with the molds.
I'd make sure the plastic level isn't too low and that you're getting proper pressure from the pot as the plastic level changes. Just my thoughts though.

IMO...I believe the problem is a combination of the molds getting to hot and the plastic being poured to fast when the mold is hot. Try placing the mold on metal to cool...the heat will disipate faster...you could also use a fan to cool the molds and set the plastic.
