sandblasting nozzles are not simple consumables, but industrial nerve endings that integrate material science, fluid mechanics and precision manufacturing. Today, we have not only achieved the localization of high-end nozzles, but also built a full-chain service capability covering "sandblasting medium selection - nozzle structure design - system performance optimization" - just as our vision in 2011: to make China-made sandblasting core components a reliable fulcrum for global industrial upgrading.
