At AICHELIN we don’t just talk about quality – we practice quality as a matter of course. We have been ISO 9001 certified since 1994. For us, production quality starts with procurement management. By choosing suppliers in our immediate vicinity, we can perform regular quality control checks. AICHELIN assembles and checks all plants in its own production facilities. All components of the very large systems are tested cold. Smaller plants are tested cold up to the fully automatic stage and some are even warmed up on the way to the approved-parts production.
