The Ware for April 2019 is a roto-molding machine. I’ve seen these machines in various sizes, but this is by far the biggest one I’ve seen to date. It’s used to mold furniture-sized objects. One thing that you don’t get from just watching an animated GIF is feeling the sheer amount of heat coming from the machine. The whole assembly is shoved into a gas furnace and heated so that the plastic is molten, and then taken out to cool over a period of 30-45 minutes, so it can get quite hot around the molds as they cool. Adi guessed this one right away, congrats and email me for your prize!
