Since the COVID-19 outbreak, Nordson has shipped many BKG NorCon screen changers to global market leading extrusion OEMs in Europe and even greater numbers of BKG BlueFlow gear pumps to OEMs around the world, including China. More orders are in discussion, according to Sven Conrad, global business director.
In the melt blowing process, extruded polymer passes through small holes in a nozzle surrounded by high-speed blowing gas, producing the randomly oriented microfibres that make up a nonwoven sheet. The BKG melt delivery components are deployed between the extruder and the melt-blowing tool. A gear pump provides the uniform melt flow and pressure required for the process to operate efficiently and with uniformly high-quality product. A screen changer filters out impurities to protect the dispense tool and yield the clean product required in medical applications.
“There continues to be an urgent need for the microfibre fabrics used in protecting medical professionals as they cope with the surge in COVID-19 cases,” said Conrad. “Like other companies in the plastics industry, Nordson supplies products that are essential in the global effort to mitigate the spread of this deadly infection. It shows once more that, given proper handling and disposal, how important plastics can be in our modern society.”
