Sell me your 30 cavity mold anger problem will be solved you will have no more bubbles before you start to feel your molds shoot little bit of plastic out first and then shoot your mold.

Apply constant pressure after the injection for 10-20 seconds and see if this helps. It does my Willow Tail and Thump It grub molds that like to get pits in the bodies.

Worm oil the mold and it will shoot easily

Thanks

If your problem is with pits in the body then it has nothing to do with air bubbles, and you should never have to lubricate an aluminum mold. Try shooting the mold very slow, it should solve your problems.

Yes that could be one of his problems.

I would say by reading his post that it IS​ his problem.
