Yup, roto-molding. A monstrous industry; toys, food service and catering, farm supplies, recreation, sporting goods, you name it. And yes, that is a catwalk around the molds. When the gyrating process stops, and they emerge from oven.
Also a great heat source come dinner hour, butternut squash, lasagna, tamale pie...bigger molds, subject to longer heat intervals.
Water tank blow molding.
