Injection Molder Progress

Got to fire up the new heat chamber in the injection molder.
Brought her up to 275 with no problems, no heat stress explosions yet!
One side welded airtight, the other side not so much, 4 or 5  leaks. Nozzle seam also leaking on one side.
But even with those problems I was still actually able to extrude plastic through the nozzle this time unlike other experiments with the longer brass nozzle.
So after some welding fixes I should be able to bring it all the way up to full heat and achieve full liquid, then we see how well it fares under full pressure.
If all goes well it's moving on to building a frame and lever (again) and then on to building some molds!
