Hessel Industries designs and manufactures complex cable harnesses for high-reliability applications in sectors such as semiconductors, special vehicles, robotics and defense.
We have experience with safety-critical harnesses for airbags, brake systems, steering, battery systems and just-in-sequence supply of main engine harnesses for automotive up to heavy duty machinery.
We co-develop cable harnesses with our customers using Design for Manufacturability (DfM) principles. The focus is on optimizing reliability, assembly ergonomics, cost-efficiency, and weight reduction—while minimizing reliance on niche or single-source components.
