ABSTRACT:
An automatic coating system for making set-up by coating a wax pattern with a refractory material, for use in a lost wax process. The system has a set-up pickup device adapted to pickup the set-ups by one from a set-up pool, a slurry dipping device for dipping the set-up in the slurry of the refractory coating material, a sanding device adapted to deposit sand to the coated set-up and a set-up taking-out device for taking the set-up out of the system. These devices are disposed on a common circle. The system further has aset-up transportation device located at the center of the circle. The transportation device has a plurality of beams extended radially outwardly to positions of the devices on the circle and supported by a shaft which is rotatable and movable up and down. Each beam has an arm which is adapted to hold the set-up. The beams of the transportation device are cyclically moved up and down and rotated back and forth to transport the set-ups from one to the next devices disposed on the circle.
