Case Study CIPG Dispensing with Atlas Copco
As electronic systems become smaller and more highly integrated, reliable and efficient sealing solutions are increasingly important. This case study explores how UV-curable Cured-in-Place Gasket (CIPG) technology from Hoenle Adhesives enables precise, automated and energy-efficient sealing of electronic housings. Combined with automated dispensing from Atlas Copco (Scheugenpflug), inline inspection and UV curing, the solution supports high-volume production with short cycle times, consistent bead geometry and reliable process quality.
Precision Sealing, Automated Inspection and Fast UV Curing
The case study demonstrates the potential of UV-curable CIPG technology for demanding applications in automotive and industrial electronics. The liquid gasket material is dispensed directly onto the housing flange, allowing complex sealing contours and different geometries to be implemented without dedicated tooling. Hoenle’s UV-curable polyacrylate CIPG combines thermal, mechanical and chemical resistance with fast curing times, while supporting automated application by needle dispensing or contactless jetting.
In combination with the Atlas Copco Scheugenpflug 8000 series dispensing technology and integrated 2D/3D inline inspection, the process enables precise and reproducible gasket application with immediate quality verification. UV curing completes the process within seconds, allowing components to proceed directly to subsequent production steps. The compatibility with UV LED technology at 365 nm and 405 nm also opens up opportunities for energy-efficient and low-maintenance curing processes.
The case study highlights how UV-curable CIPG sealing can combine design flexibility, process reliability, fast curing and automated quality control for the production of modern electronic housings and assemblies.
