US Patent 5,495,917

Pax is the pioneer of in-die lubrication.  Since 1980, Pax Lube Systems have been giving stampers the opportunity to be more productive.  The Pax system was designed and manufactured by skilled tool and die craftsmen and tested in our own stamping facility.  Through the use of the Pax Lube System, production speeds have increased, part quality has improved, die life has been extended, and lube consumption has decreased.

The Pax Lube Systems are "pre-pressurized".  The lubricant is supplied to the manifold under pressure.  A constant and consistent supply of lubricant is provided.  As long as there is a supply of lubricant in the reservoir, there will always be lubricant available at the distribution pumps.  It also means that the distribution pumps work more efficiently because no priming is required.
