Development of Dry Lubricants for Stamping of Automotive Parts

Introduction of a new lubricant in the press shop involves various demands beside the pure tribological. Often, environmental concerns are considered most important. For the automotive industry specifically, compatibility with existing cleaning and painting systems as well as different joining techniques are key factors for acceptance of a new lubricant. The lubricants must of course also provide enough corrosion protection during storage.

The present paper reports results from a screening of existing dry lubricants. Critical properties for further development are identified and some results from improved products are also included.
