Quick Die Change, Quicker Lubricant Changeout

How Lubrication Strategies Affect Changeover Time

Excerpt from the article in the September 2012 issue of Stamping Journal by Troy Turnbull

To survive, a person’s body relies on getting fluids to the right places at the right time, and the same goes for the stamping process and die lubrication. When should the lube turn on, and for how long? Does the process require flooding, split-second lubrication, or minimal lubrication? The list of variables goes on, and if a technician overlooks any one of them, he may produce rejected parts, damage tools, and cause lost production time.

Stamping requires a system to distribute the die lubricant mixture accurately, thoroughly, and economically with the proper pressure and volume to supply fluid consistently to each spray nozzle. Stampers must ensure nozzles are positioned properly and the lubricant mixture mixed correctly, with proportions tailored for the application. Finally, stampers can find ways to optimize changeover to reduce setup time and, just as important, the possibility for press setup error.

How to control lubricants for better housekeeping

Excerpt from the April 2003 issue of Stamping Journal by Stan Reinke

Effective application of die lubricants typically is overlooked in many stamping facilities. Many companies try to get by with applying as little lubricant as possible, just so they don't have to deal with the mess.

However, metal stampers need to move away from thinking of in-die lubrication as a necessary evil and instead view it as a powerful tool that, when applied effectively, can improve die life, press speed, and part quality.

In many applications, the lubricant first is applied to the stock. Some companies use roller coaters for this job. However, for operations in which the lubricant must be reapplied in the die, spray lubrication often is required.
