Soft plastics drying too quick

Recommended Posts

I’m very new to this and I’m using all do-it products which I’m now reading was probably not the best idea.

im just a little confused because im watching people shoot a few different molds on YouTube where as i can barely fill one before the tip of my injector is clogged. I’m using their plastisol with a few drops of heat stabilizer heated to 350°
 

is that an issue with me not stirring enough or is it the product.

I highly doubt it’s your plastisol. Are you certain your temps are at 350? What thermometer are you using? Is it cold in your work area?  Your mold may be too cold to begin with. And your injector as well. Heat them both up before you begin.  I pop mine into an oven. Start with these easy fixes first.

Not a fan of their plastisol, never had good luck with it. I'd suggest a gallon of Bait Plastics 242, low bubbles and REAL forgiving to work with. Heat to 350-360, add colorant & flake, then make sure you are injecting around 315-330 deg. After you get your color & flake right, if you dont re-heat you may be shooting at too low a temp & the plastisol is too cool. You dont have to hold too long on your injector either, a few seconds is all thats needed. Top off the sprue and move on to the next one. I always put the cup back in the micro too, keep it warmer longer and allows any leftover bubbles to go away.

 Agree above,

Sounds like things are getting cooled off to soon. 

 Not the product at all.

Temp & speeds are pretty crucial when shooting plastics. Heat it to 350 & shoot quick. Like said above heat the injector if it's cold. I mix in colorant & flake most times before heating unless i'm making a totally new color that i haven't figured out the mixture yet. This way i prepare the mix, heat to 350 & inject like a well-oiled machine   more or less  :whistle:    & seldom have any problems at all. The more you do it the more you'll get your system worked out & the problems pretty much become a non  issue.
