Field notes
The page describes orders based on drawings, samples, or application context, and lists both custom design and reverse development. Its process includes material-certificate checks, CNC coiling and grinding, shot peening, inspection, and fatigue testing. The manufacturer says each robot-spring package carries a production date and batch number; it also gives a sector-by-sector sales mix, though these figures are self-reported.
