Pilot Electrospinning Machine is a semi-industrial scale electrospinning nanofiber production machine that can coat substrates with different nanofibers. This production line can be offered in both needleless or needle-type e-spinning. In the needleless production line, the needleless rotary spinneret is partially immersed into the polymer solution and a high strength electric field is applied to the solution bath and collector (rotating drum). This results in the formation of numerous jets from the spinneret and consequently, the formation of a layer of nanofibers on the collector.
