4.5 swim shad

Just got this mold.  One bait shoots perfect and the other comes out with a dent.  I've tried clpimg different, shooting at 3 different temps.  Always the same though. The bottom bait has dents and the top one is perfect.  Any thoughts?

Most dents can be attributed to one of three things , time , temperature , pressure . Are you keeping the pressure on for a few seconds and are you topping off your mold so as the plastic shrinks it can draw from the sprue .

I shot the mold at 350 340 and 325.  I top the mold off. I'll try the pressure.  Thank you.

Your welcome , By the way some molds will dent or not fully shoot if you have them clamped too tight . Never had a CCM mold that dented but I have others that will . One in particular is a ribbon tail . I have to shoot it at 360 and tighten the bolts finger tight only or that sucker will drive you to drink.

Ahh haa, so I need to shoot ribbon tails to justify another bloody mary!

Go as cool  as you can. Dents are caused by the uneven cooling within a large area of plastic. I think there is another thread on this issue....and that was the recommendation (along with holding pressure).
