Happened once, IVO SpeedPressVest. Unit was no good. Was a trial of investment. I've stayed with using
my PCI Plus investment.
Looks like that's a 100gm ring. You need to follow the ten mm rule. Or get a Super Ring.

That unit is not sprued in the heat center of the ring.

Quite possibly. The IVO Tech support told me they press even single units in a 200, no small ring. Maybe their trying to tell us something? My miss press pic was over a year ago. Now I'm able to use 200 rules in my super ring while only using one pack of investment. All is good.It will still be the same principles just on a slightly smaller scale.
Over the plunger is in the coolest part of the ring.
Lots of labs try to save money and stain like crazy. I've seen some crazy stuff I couldn't even believe. Like why not use up those MO ingots that have been laying around for so long and press whatever we have to and stain the hell out of it...Who the heck press A1 to achaive A3? It is crazy. Or may be i am the crazy one!!
45-60 degrees max outward not inwards is the max angle to sprue. 45 works well. Looks like you were really close to the outside of the ring, aint no anything detection going to cure that issue. User fail! But what in the world is that extension on the bucal? Is that part of the design or extra material from a air bubble? What is that?
I had a tech tell me he would take his rings out of the silicon ring formers after about ten minutes to let it cool. Why I don't know.
