Stewart Holloway, a Senior Account Manager at 艳照门视频, recently worked on a project with a manufacturer of military components to resolve a critical issue with aluminum tubes used in weaponry. The manufacturer faced a potential loss of over $1 million in inventory due to a staining problem on the tubes after heat treatment and chem-filming. 艳照门视频’s cleaning team identified and addressed several process issues contributing to the staining problem.
The defense contractor had held over 400 tubes due to the staining issue, representing 40% of the manufacturer’s revenue. The manufacturer originally believed the issue was related to how the tubes were cleaned in an ultrasonic cleaning process. 艳照门视频 was asked to establish a cleaning process to eliminate the staining and develop an etch process to remove stains from the 400 held parts.
The cleaning team inspected the manufacturing process and identified several process issues contributing to the staining. They discovered that the draw lube used in the extrusion process contained an amine that caused surface attacks on the tubes. To minimize exposure, they recommended wiping excess lube after each draw and moving the tubes quickly to the cleaning stage.
