RotaPlasma™ HS1 is a unique high-speed rotating plasma gun manipulator. It greatly enhances the capabilities of a standard plasma gun by providing continuous rotation during spray operations. It can be used to coat both uniform and non-uniform inner geometries. RotaPlasma HS1 forms an integral part of the Oerlikon Metco’s SUMEBore™coating solution.


Typical applications

Engine block cylinder bores
Heat exchanger tubes
Pump casings
Turbine engine transition ducts
