✦ Certified by TÜV since 2004, we undergo an annual professional factory audit conducted by TÜV experts, with the most recent certification issued in September 2025.

✦ Comprehensive process documentation ensures full traceability for each product: horizontally over a 10-year period, and vertically through the entire supply chain down to individual supplier production batches.

✦ Each product is assigned a unique identification code (One Product, One ID).

✦ Not only does 100% of our output undergo strict quality control before leaving the factory, but 60% is also produced and controlled entirely in-house, starting from raw material powder metallurgy.
