Customer Background: A Tier 1 automotive parts supplier, mainly producing engine aluminum housings with an annual output of 5 million pieces. The original process used traditional chlorinated solvent cleaning.
Problem Diagnosis: The customer reported occasional white spots on workpiece surfaces after cleaning, with a yield rate of only 92%. Monthly losses from rework and scrap due to cleaning issues amounted to approximately 150,000 RMB. Diagnosis findings: 1. Traditional solvents caused mild corrosion to aluminum alloy; 2. Cutting oil in blind holes was not completely removed; 3. Rapid solvent evaporation left water stains.
Solution: Switched to TS-200 Automotive Parts Hydrocarbon Cleaner + vacuum cleaning process. Three months after implementation, the yield rate increased from 92% to 99.2%, and annual rework and scrap losses dropped from 1.8 million RMB to 140,000 RMB. Additionally, with cleaning agent reused through distillation recovery, annual procurement costs decreased by 42%.
