Towards circular business models in the punching industry: Leveraging smart sensor technology for sustainable manufacturing processes

The punching industry (PI) remains largely dependent on unsustainable resource use in its manufacturing process, consuming finite materials. Evolving market needs for increased environmental sustainability in the PI cause punching companies to reevaluate their existing manufacturing processes. Considering this trend, this research explores the prerequisites for transitioning to circular business models (CBMs), a subset of sustainable business models, by using smart sensor technology (SST) supporting a sustainable manufacturing process (SMP). Prior research has shown that using different sensors pertaining punching tools and machines is prevalent. Standard parts in the punching tool itself address these challenges of an imprecise set-up of the punching tool on the punching machine resulting in process improvements and efficiency enhancements. Yet, no similar data-driven punching tool concepts have been installed highlighting the novelty. To address this gap, this study examines how data can be gathered and successfully utilized to support SMP fostering CBMs in the PI based on data-driven punching tools. Mixed methods are applied in a practice-oriented project, involving a Swiss-based manufacturer. The results demonstrate several key drivers supporting SMPs enabled by data-driven punching tools. Future research should involve a larger number of interviews and further field testing to increase maturing SST data-driven punching tools.
