Robonext P is an innovative PTA equipment for welding of Blow-Blow, Press and Blow and NNPB glassware plungers. The machine has an integrated automatic loading and unloading system. Thanks to an optimal control of the welding pool guaranteed by the new performing nozzles designed specifically for this application, the deposit is carried out in a constant and optimized way, a penetration of a few tenths well anchored which guarantees the typical advantages of the PTA process. Moreover – unlike traditional spraying systems – this system allows the deposition of higher performing alloys at high temperatures such as the Cobalt – Stellite alloys – with a much lower consumption of powder material.
