Powder Feeders

Powder Feeders

Powder Feeders supplied by Flame Spray Technologies are designed for all Thermal Spray applications. Our Feeders have excellent track records in providing high precision and repeatable powder feed for all coating, laser or welding processes.

FST-10 & FST-20 Powder Feeders for Thermal Spray applications


The FST-10 and FST-20 feeders are available as Single or Double versions (equipped with one or two powder feed lines). With the Double versions, the two feed lines can be operated separately or simultaneously.

They are also available as stand-alone units. Stand-alone feeders can be operated independent from the coating controller and therefore can be integrated with all available and existing thermal spray or laser and welding systems. The feeding system, based on the volumetric principle, provides continuous feeding and precise and reproducible powder feed rates. The powder feeders are equipped with mass flow controllers, or alternatively with rotameters, for accurate control of the carrier gases.

When integrated with the FST MP-50 Multi-Process Coating System, all powder feed functions are controlled from the MP-50 Touch Screen Panel or as part of a stored spraying recipe. Stand-alone feeders have an independent control panel for setting the required powder feed parameters. The hoppers can be equipped with special disc and spreader/suction units for low and stable powder feed rates for PTA or Laser applications.

The FST-10 or FST-20 powder feeders are equipped with 1,5 ltr. or 5,0 ltr. hoppers (other sizes are available) and can be equipped with heating devices, as well as weight balances to enable closed loop control of the powder feed operation. The powder hoppers are designed for high carrier gas pressures.

FST PF-50 Powder Feeder for Thermal Spray applications

Powder-Feeder-50The FST Powder Feeder model PF-50 is an open-loop pressurized unit specifically designed for thermal spray applications. Based on the proven volumetric-feed technology, the PF-50 is an economical powder feeder for all powder-based thermal spray processes (A High Pressure version is available for High Pressure Processes such as Diamond Jet).

Its proven design, unparalleled powder feeding accuracy and repeatability, and its attractive price level has turned the PF-50 into becoming one of the standard powder feeders in the Thermal Spray industry.
