Program a machine that applies acid to precision-etch metal and plastic.
Casts plastic footwear, performing any combination of following tasks, and working as member of crew: Fills mold under spigot, or mold fills automatically as it moves on conveyor. Empties mold into vat and places it top down on rotary conveyor rack to drain off excess. Removes mold after one rotation and places on conveyor that carries it through oven to gel and dry. Repeats entire process to increase wearability by adding second thickness. Holds mold under spigot and adds liquid, tipping mold back and forth to build up even thickness of sole. Adds additional plastic to heel area to increase thickness of heel.
