This NADCA series will look at, die sprays, plunger lubricants and their effect on casting quality.
With an in-depth discussion of both die and plunger lubricants we will look at their chemistry, function, application and effects on casting production and quality. The course will review pulse spray, its application and results at two production facilities. Hydrostatic spray will also be reviewed with application examples and use of hydrostatic spray.

Part 1 - Fundamentals - This course will go through the fundamentals of die casting lubricants. The course starts with the basics of the conventional use of external lubrication and cooling of die cast dies. The methods of spray application and the reason lube is applied to die casting dies. The function, chemistry, care and maintenance of the lubricants is reviewed. The spray section ends with review of potential defects caused by variation in spray application. For each defect, solutions to resolve those defects are taught.
