Brazilian manufacturer Rotoline Industrial Equipment has developed the world’s first rotational molding machine with a spherical oven. Lacking doors, the design of the Sphere Oven SO 1.60 splits at the equator to open vertically; Rotoline says this allows a more homogeneous air flow, reduces heat loss and increases efficiency.

The SO 1.60 has been designed to be fully automated, from weighing and feeding the stock to removing the part; the former is achieved by built-in scales—up to four, in case you’re using different colors—and the latter is tackled by robotic arms.
Here’s a video of the machine in action. It’s all in Portugese, but you can figure out what’s going on:
