Xymox – Die Cut vs Laser
Die Cutting Process and Eco Impact
Die cutting involves shaping materials using custom steel dies and presses. To understand its environmental impact, it’s essential to examine energy consumption, waste generation, and material efficiency.
Energy Consumption in Die Cutting
Die cutting relies heavily on mechanical presses and steel dies, which require significant energy during both the cutting process and the production and maintenance of the dies themselves.
In fact, machine tool electricity accounts for 75% of manufacturing energy use and 90% of industrial energy consumption. This highlights the importance of optimizing machine settings and material choices to enhance efficiency. For instance, a packaging company improved its sustainability efforts by switching from traditional cardboard to recycled composite materials. By adjusting their die cutting machine settings to accommodate the new material, they achieved cleaner cuts and reduced energy use.
Energy consumption directly ties into waste production, which is the next critical area to consider.
Waste Production in Die Cutting
The die cutting process generates waste primarily in the form of leftover material surrounding cutouts, scraps, and damaged pieces caused by poorly maintained dies. Additionally, the disposal of steel dies after their lifecycle contributes to waste.
However, innovative recycling solutions are emerging to tackle these issues. In 2021, Batavia Container Inc., in collaboration with Mid America Paper Recycling, recycled outdated dieboards into products like lawn mulch and other wood-based items. A specialized chipper separated the metal components from the wood, making repurposing possible.
"Preventing old cutting dies from ending up in a landfill will help all of us." – Paul Mansour, Director of Account Development at Batavia Container
"The boards were sent through a high-tech wood chipper that can separate the metal tool from the wood. The resulting wood chips can be reused as mulch and other wood-based products." – Paul Pirkle, President of Mid America Paper Recycling
Precision engineering and advanced nesting techniques also help reduce waste. CAD software can simulate the die cutting process, highlighting areas for improvement, while nesting algorithms optimize the placement of cutouts to use materials more efficiently. Automated waste removal systems further enhance production quality by preventing tool damage and minimizing material defects. These measures underscore the need for thoughtful material usage to boost sustainability.
Material Usage in Die Cutting
One of die cutting’s strengths lies in its ability to maximize material efficiency.
