This machine is designed to weld a ball valve to the neck opening of various bulk polypropylene tanks. We built integrated sensors to verify part presence, position and orientation. The decision to use programable actuators was made to ensure extreme accuracy as well as process flexibility. The part weld depth is precisely controlled while part temperature is closely monitored with the tooling being actively cooled while in use. We also built in a feature where, if required, inert gas can be introduced during the weld cycle.
