Estimating ROI for a Die Lubrication System
Customers who have installed Pax in-die type lubrication systems have typically realized costs savings and increased profitability one or all of the following areas: Increased Production Speeds and Part Consistency Increased Die Life Reduced Lubrication Usage. Increased Safety and OSHA Compliance as a reult of better controlling, containing, and collecting lubricantThe increased profitability/savings realized varies greatly depending upon the type of stamping application being performed and the method in which the lubrication system is installed. Typical savings for each of these categories are briefly outlined below and the attached “Sample Worksheet” can be used to estimate the ROI that you may be able to achieve in your specific application.
Increased Die Life, Production Speeds and Part Consistency:
These are the areas where Pax customers have achieved the greatest ROI. By reducing either the friction and/or the heat at a specific station or stations, customers have consistently increased both their production speeds and die life by factors of 2 to 3X. This is especially true for longer dies, dies that have gulling issues, and dies that are doing heavy draw work.
Savings from Decreased Lubrication Usage:
Although this is typically the smallest amount of savings achieved from a system installation, this is the savings that many customers will attempt to use for project justification. While the savings from reduced lubrication usage may not always be great, they are typically easy to estimate. Customers who have implemented in-die lubrication systems but have not implemented a recycling system, have typically seen lubrication usage reductions ranging from 20% to 70%. Customers who have also installed systems that recapture and reuse the lubricant typically see lubrication usage reduced by 80% or more. If you know how much lubrication you currently use and the cost of this lubrication, it is fairly easy to estimate the potential cost reduction that can be achieved. Unfortunately, in most cases, ROI’s that are based solely on lubrication savings will not be sufficient to justify the project.
