Metallisation Limited reports that it has launched a new and versatile universal powder feeder, the Metallisation PSPF I I (Plate 2).
According to Metallisation it can be used not only with the company's own plasma, HVOF and powder spray equipment, but also with spray systems from other manufacturers.
A consistent flow of powder, whatever the spray process or materials being used, is said to be ensured through the use of a rigid transverse screw with a closed loop speed control.

Metallisation PSPF I I powder feeder
In Metallisation's opinion this new robust design, leading also to easier maintenance than ever before, means that, whatever the feeding problem, the unit will not sustain damage to the feed mechanism or drive system.
For difficult-to-feed materials, an oscillating vibrator tumbles the powder, to avoid segregation of multi-component powders, or powders with a wide size distribution.
The speed of the screw is clearly shown on a digital display panel alongside the speed programming controls. A sensor on the screw sends speed data to the closed loop electronic control to ensure full control of the screw rotation and, consequently, of the powder feed rate.
The Metallisation PSPF I I also integrates with other control systems to give warning of low gas flows or blockages of the powder feed tube or spray nozzle.
The unit can be mounted on a fixed ground or wall stand, or can be fitted with castors for movement around the spray area.
