Sensor quality at the touch of a button

KUALA LUMPUR, Malaysia - Jan. 21, 2025 - PRLog -- Modern cars feature advanced input systems, touchscreens, and sensors, making driving safer and more comfortable. Hoffmann + Krippner GmbH, experts in complex input systems, contribute to this innovation. They ensure top quality with in-house testing using igus drylin technology.

Electronic components using screen printing
Hoffmann + Krippner GmbH tests printed electronics using conductive inks and pastes on various materials. Serving industries like automotive, cosmetics, medical, and aviation, they offer over 2,000 products globally. Founded in 1973, they employ 250 people and had a turnover of €30.9 million. With increasing product numbers, Hoffmann + Krippner automated their quality control, which includes electrical and visual inspections. Previously done manually, these steps are now performed by a test cell using robots and igus drylin ZLW-1040 and ZLW-1080 toothed belt axes.

One million sensors per test rig
Hoffmann + Krippner test one million sensors per rig annually, using robots to handle components every ten seconds. They rely on durable, maintenance-free drylin ZLW toothed belt axes and W pillow blocks from igus, which are lubrication-free and easy to maintain, offering superior friction performance.

Landeck and Mechler chose an electrical control system with drylin ZLW over a pneumatic solution due to cost. Hoffmann + Krippner found the drylin ZLW-1040 easy to install and customizable. They use igus's modular system for drive technology and the drylin D1 motor control system. The robot's cable is guided by an igus energy chain.

Long cooperation, sharing of ideas
The collaboration between igus and Hoffmann + Krippner has lasted over five years, marked by excellent communication and quick implementation of new requirements. Their drylin toothed belt axis has been reliable and maintenance-free. As automation needs grow, Hoffmann + Krippner plan to continue working with igus.
