Okay, so I finally started shooting baits with these molds with mixed success... I have been getting big air bubble "voids" in the tips of my feet as well as smaller air pocket voids around the eye sockets... I have tried shooting slow or fast, hotter or colder, etc.
I know it must be air getting trapped in the mold... As I am drawing plastic into my injector, I keep
the tip below the plastic surface at all times... I am just trying to figure out how air is getting into my plastic, and/or if I am doing something completely wrong...
It is an awesome feeling to shoot five molds and get five great looking baits, and it is a very depressing feeling to shoot five molds and get only one good bait...
Oh and one more question, how do you minimize overall scrap?!? It seems like I get A LOT more overall scrap with injection then I did with hand-pouring... I was wondering if there were any good tips out there on this subject as well...
Any help would be GREATLY APPRECIATED!!! Thanks!!!
One more thing I should add to the information stated above... Towards the middle and end of the existing batch, we added batches of remelt to the existing mix of plastic in the presto... Basically what we did is throw about 8oz. of new plastic in a pyrex with equal amounts of remelt and heated it to temperature and then added it to the already hot plastic in the presto... Could this method also have a negative affect on how the baits will inject?!?
