Taking Aim at Fixing a Black Oxide Coating Issue
Case Study
A firearms manufacturer faced issues with black oxide coating defects, leading to high reject rates and inconsistent quality. Hubbard-Hall identified poor chemistry maintenance and contamination as key problems, implementing a comprehensive solution to restore process efficiency. By cleaning tanks, adjusting wastewater treatment, and introducing advanced chemical solutions, the team significantly improved coating performance. As a result, black oxide rejects were reduced by 80%, plating finish quality dramatically improved, and chemical usage decreased.
