Efficiency and Sustainability

Our objective is to minimize cost and impact to the environment. Those are the drivers behind our equipment maintenance program, which has us regularly upgrading and replacing presses and other machines to ensure we’re always using efficient, capable and reliable equipment.

For example, over 75 percent of our presses are now all-electric, and we’ve upgraded to cooling technologies that use up to 98 percent less water than traditional industrial cooling systems. Additionally, our Manufacturing War Room – one of our many powerful processes - serves as an ongoing effort to minimize waste, including in the areas of material and energy.
