So we built a small injection machine to speed up production. Though we had to wait 7-8 minutes bevor we could make another face shield frame, because the plastic flakes had to heat up. \n\nTo reduce the time-per-part we invented the Rapid-Fire-Method. Using our extruder we produce hot munition for the injection and instantly process it.\n\nWe made a video how to do this.
