Circular saws to cut the sprue from the crankcase. It has been designed to form part of the cell of the ABB robot that unloads the injector in the same way as on the sprue cutting station. The robot unloads the part from the injector, waits for it to cool down and then places it at the cutting station where the sprue is removed by the saw, while a vertical cylinder breaks the troughs. On completion, the robot unloads the part onto an outlet ramp of the cell.
