Awarding of quality work and precision

Quality is one of the cornerstones of our strategy.
 At the customer’s request, we voluntarily undergo audits.
 Since 2000, we have operated on the basis of a certified quality management system in accordance with PN EN ISO 9001.


We support our suppliers in their further development through audits and incoming material inspections.
 Quality control of the finished product includes visual inspection, 100% functional testing, and random sampling based on the Acceptable Quality Level (AQL).


We carry out tests to confirm compliance with safety requirements for electrical equipment that require VDE certification.
