PaperShell

“We turned to AP&T for numerous reasons – primarily, because it is a Swedish company with solid experience of meeting the stringent requirements of the automotive industry,” says Fredrik Westerberg, Production Manager at PaperShell.

The first steps of the exciting collaboration between the companies were taken when the Research Institutes of Sweden (RISE) used an AP&T servo hydraulic press to test-form bio-composites. Employed at RISE at the time, Westerberg collaborated with the AP&T team to develop a line concept for large-scale production of bio-composites. Westerberg intensified these efforts when he became PaperShell’s production manager.

Fully automated, flexible and energy-efficient

With the new material’s specific characteristics in mind, PaperShell and AP&T developed a fully automated, flexible and energy-efficient production line concept making it possible to rationally and efficiently manufacture components for many different areas of application using one and the same line.

“We truly believe in PaperShell and their new material. It is very exciting to be part of realizing a production solution starting from the test environment and moving on to its industrialization, all the while dealing with process control and flexibility challenges. The fact that we can now make a contribution to creating sustainable components and products is fully in line with our own sustainability ambitions,” says Patrik Haglund, Business Development Manager at AP&T.

Today, one production line is already running for test-manufacturing in PaperShell’s factory in Tibro. Operations will scale up during the course of 2024 with more lines being brought online to increase capacity.

The manufacturing process is fully automated. The raw material is reinforced paper on rolls, which is cut into “blanks”, pressed and formed at elevated temperatures. According to Haglund, the magic is in the combination of heat, pressure and a binding agent. 

To minimize the need for intermediary storage, labeling, cutting, stacking and inspection are all done in the same line, and all under the supervision of the line’s process monitoring system which ensures that the end products are of the right quality.

“The technical level of the equipment is on par with the most current press-hardening lines we deliver around the world. This lays the foundation for a stable, secure and extremely energy-efficient process,” he says.

Great growth potential

Thanks to the modular setup of the lines, they can be customized to any needs or demands. A great many stakeholders are interested in the multi-faceted material, and ideas for potential areas of application are constantly popping up. This points to there being great potential to grow internationally.

“Through the years, we have joined many of our customers out into the world. As an established, globally active company, I would say that AP&T is well-positioned to join PaperShell on their journey. For me personally, it is fun and challenging to work with a customer that is not only quick, innovative and professional, but who also knows what it takes to grow quickly!”

PaperShell’s CEO Anders Breitholtz and his team are also very pleased with the collaboration.

“AP&T has been an exemplary supplier and development partner on many levels, not least when it comes to working intelligently on sustainability matters. When we presented our challenge, AP&T was quick to come up with a solution that drastically reduced our energy consumption. We are expanding as planned and are excited to see what we can accomplish together in the future.”
