Eberle GmbH Co. KG: Sealed Seam Testing to Ensure the Highest Quality
Case Study
- Customer: Eberle GmbH & Co. KG
- Location: Wurmberg, Germany
- Industry: Medical
- Topic: Testing the sealed seams of sterile packaging
July 2025
Eberle produces and sells sterile medical instruments that are packaged in blister packs with Tyvek film. The Tyvek film is bonded to the blister pack using high temperatures and high pressure. The resulting seal seam must meet certain conditions to ensure sterility later on. The zwickiLine is currently used for the peel test to determine the strength of the seal seam.
Eberle GmbH & Co. KG: Expert in minimally invasive medical technology
Eberle, based in Wurmberg, is a manufacturer of medical devices specializing in the fields of minimally invasive surgery, particularly orthopedics and endoscopy.
The company offers a wide range of surgical instruments and drive systems, which are developed in close cooperation with medical professionals to meet their specific requirements.
Eberle's products are subject to strict quality controls to ensure compliance with the medical industry’s high standards. The use of state-of-the-art CAD/CAE systems supports the design and development of medical devices, which strengthens the company's innovative capabilities. The company attaches great importance to technical precision and reliability in order to continuously improve the safety and effectiveness of surgical procedures.
Optimized laboratory processes and future-proofing through remote support
The company faced the challenge of making an investment in its laboratory equipment that would be future-proof and ensure both high product quality—for example, when testing seal seams for surgical instrument packaging—and long-term reliability. At the same time, a fast and efficient response to technical challenges was required in order to minimize downtime and ensure the continuous performance of the laboratory.
ZwickRoell responded quickly to the company's needs, including with a competent and comprehensive laboratory demonstration in Ulm. This demonstration enabled Eberle to experience first-hand the high level of vertical integration and quality of the solutions offered. The decision in favor of ZwickRoell was made not only because of the impressive demonstration, but also because of the future-proof technology offered by the testing machine manufacturer. The company currently uses a 2.5 kN zwickiLine and a Rockwell hardness tester for its tests.
By implementing ZwickRoell solutions, Eberle benefits from the quality and future-proofing of its investment. Another key advantage is ZwickRoell Remote Support, which enables remote diagnosis of technical problems. This feature has proven particularly valuable, as it allows the company to respond quickly and effectively to challenges without having to wait for in-person service visits. Overall, ZwickRoell solutions enable the company to carry out its laboratory operations efficiently and with high quality. Remote diagnosis and remote support have also helped to significantly reduce potential downtime and increase efficiency.
