1. He would create different mixtures and whatever yielded the best results for his specific application was what he used. Although much was learned from this trial and error type of evaluation, this method of die lubricant development was considered more of a “Black Art” than a science. Several decades later, there are some who still believe it. Over the years, die lubricant manufacturers and others have gone to great lengths to develop laboratory methods aimed at correlating a product’s performance in the lab with how it will perform in production, and yet there are still no standardized scientific methods within the industry for evaluating die lubricants. The only true test to determine the functionality of a new die lubricant is by its introduction to the production environment.
