Improved Metal Stamping Lubricant Testing Using Controlled Formed Panels 2010-01-0990
Modifications to the Limiting Dome Height test method and instrument enable in-lab production of controlled metal panels that can be used for cleaning and coating testing after stamping lubricant performance testing is complete. The differences in results between stamped and unstamped (flat) panels on a variety of common stamping lubricant acceptance tests will be explored using existing approved stamping lubricants. The value of using a standard stamped part for lubricant, cleaner, and coating development will be described. The importance of real-world process simulation will be reviewed in the context of coating failures.
