Schwing Technologies, headquartered in Neukirchen-Vluyn, Germany, will showcase its solutions for the efficient removal of polymer from large, contaminated components following nonwovens production at the upcoming INDEX 2020 exibition in Geneva.

Components such as meltblown and spunbond dies which can be up to six metres long, as well as spinnerets, no longer need to be flipped using the company’s double-sided, alternating ultrasonic units.

The optimised process saves manpower, shortens cleaning times and reduces machine downtimes in the process of removing PET, PP and PE and other polymers from the components.

“Until now, the ultrasonic cleaning process required two work steps, but thanks to our new two-side sound, the machine parts no longer have to be manually turned,” said managing director Thomas Schwing. “In addition to the benefits in time and effort, the process also minimises the risk of damaging dies.”

At the exhibition, Schwing will also provide information about the company’s Vacuclean vacuum pyrolysis cleaning system. This process, which takes about 8 to 12 hours, involves several cleaning steps, including thermal cleaning of components, subsequent high-pressure washing and ultrasonic cleaning.

Safe and material-friendly technology measures the precise temperature directly on the part and guarantees residue-free results – even inside mounted components or complex tooling. The Vacuclean system consumes very little electrical energy and is equipped with a special catalyst to treat fumes, protecting the environment.
