Cleaning weld seams on outer and inner surfaces in a targeted, sustainable and efficient manner To avoid quality issues during the subsequent cathodic dip painting process, a renowned automobile manufacturer relies on Ecoclean’s EcoCbooster technology for cleaning weld seams on integral subframes for electric vehicles. In contrast to the previously used method of solid media blasting, which requires an additional aqueous cleaning step, this virtually wear-free, fully automated process removes welding residues from the exterior and interior of parts in a targeted, resource-saving and cost-saving manner without the need for abrasives.
