Electrostatic powder coating machine model RSC
Zurück
The machine model RSC was designed for an even, finely dosable and absolutely dust free powdering of cables, wires, hoses, profiles with powders like talc, stearate, lac powder, swellable powder etc. Due to the electrostatic charging of the powder a strong adhesive power on the product and a very even layer on the surface is reached. The electrostatic also makes sure that no powder will fall from the product outside of the dusting chamber. Depending on extrusion speed and product diameter one up to four powder guns of 100kV each are used.
The Rolf Schlicht portfolio covers machines for the smallest product diameters up to 160 millimetres. The machine will be manufactured corresponding to the desired extrusion speed and diameter. In the machine there is a fluidised powder hopper out of which the powder is sucked by pneumatic venturi pumps and blown to the guns. For an optimal adjustment of the powder quantity the power of the electrostatic charging can be adjusted from 0 to 100kV, as well as the powder quantity and the speed of the dust cloud. Depending on the product the powder gun can be equipped with different powder nozzles. In the machine there is a fully automatic and maintenance free filter system which is not longer cleaned off by blowing in compressed air. Thanks to this filter system a strong and constant vacuum is generated in the machine, so that no powder will escape into the ambient – guaranteed. Inlet and outlet openings of the dusting chamber do not have to be sealed by brushes etc. If there is not enough space in the line to place the machine Schlicht also offers a free standing dusting chamber which is connected to the machine by hoses. For an extremely fine powdering of slowly running products a fine dosing device is offered optional to make sure that only a breath of powder is transported to the guns.
