Here’s one formula from many years ago hope this helps you out. The last part is for sinking plastisol. Remove if not desired.
65% DINP Plastecizer
-13% Emulsion PVC paste resin
-2% Epoxy Soybean Oil
-5% Metallic Thermostabalizer
-5% Dispersent
-3% Glycerol or Glycerin
-7% Tungsten Nano-particles or Tungsten powder 275 mesh and up
The temperature stays within two degrees for hours and hours. And glitter and salt will build up on the side of the injector but not bad enough to make a difference in a bait. After the plastic cools you can pull out what’s left and see it is not burned and no big areas of glitter or salt. But sorry whatever test you did came out with that conclusion. Been using this type of system for years and years.
Next Level injection machine used to keep plastic at temp and heat the basstackle Twinjector so there is no need to clean out every time. Can boost production in no time at all. Also laminates are a breeze when you know the actual temp of the plastic you are using. You will have to supply your own presto pots and Basstackle Twinjector. Custom anodized one will be available from time to time.
Baitplastics does leave a residue. It’s more of a sticky surface thing. But all plastic I have used do this and I have cleaned it up with this stuff the whole time. No scrubbing it just wipes off.
Mine is about 10 years old and the oil is white from sucking up plastic. Still works fine a little slow but same vacuum. Let it run for awhile and see if it gets better. I paid 69 for mine.
For years what we call pearl is mica. So yes it will work just fine. Car paint,house paint, makeup ,hobby paints and pretty much all thing that say metallic are mica powders in some form or another. Crushed up rock is all it is.
Funny I saw this just as I posted mine. Now I know why you never had one before you used MF plastic. They do something different than all others and don’t have bubbles. But it comes at a premium price too. When I bought my first drum of plastic that I had to use a vacuum I saved so much money that I bought a chamber and still had extra savings. Ever since then I have saved more and more. Still have the same one that cost me 250 then but it falling apart from years of use.
I get what you are saying but he asked what size pot not weather it was worth it or opinions of using one. My guess is he can see the bubbles in his baits and does not like it. My guess for you is that you can’t and does not matter. I have had mine for years now and never pour without it. I poured a lot of transparent baits and you could see them. But in another case the bubbles were gathering at the nose of the bait causing a weak spot if you use a spring lock. For that matter a barb on a jig hook. So it is not always just for looks.
I see no reason for using it in a silicone mold either. If you are worried about bubbles in your mold but not the plastic then it just the same. The bubbles the vacuum takes out of plastic don’t rise fast. Big ones do but the ones that cloud up the clear plastic don’t. Different people have different standards and expectations. Fish don’t care about a lot of things but the fisherman has to like it enough to put it on his hook first before the fish ever sees it. So it’s not about what the fish like is it.
