Flame Spray Technologies, The Netherlands, has introduced a state-of-the-art mass flow controlled UHP/HVOF eGun coating system that reportedly enables cost reductions up to as much as 25% compared with conventional liquid-fuel HVOF systems. It produces coatings with higher density due to higher particle velocity, and lower oxide levels due to a fuel-rich reducing flame.
Coatings also provide an improved corrosion barrier as a result of both lower porosity and lower oxide levels. The eGun system separates fuel, gas, and electrical components into distinct modules. Flow, pressure, and temperature sensors are installed to monitor the process and provide warnings when the system is operating outside of its specified limits.
In addition to controlling FST’s eGun, the system is also capable of operating the JP-5000 Model 5220 kerosene HVOF torch. This allows the customer to use either the new eGun or conventional JP-5000 technology. The JP-5000 feature is optional.
The standard eGun System is supplied with a PF-50 Powder Feeder. However, the system supports most commercially available powder feed units. This flexibility gives the customer the opportunity to select the preferred feeder without compromising the overall system quality or performance.
The eGun System uses an operator friendly full-color touch screen that allows for easy programming and process monitoring. It can store up to 256 recipes.
