Eighty years ago, pioneers gripped hammers with cracked hands and peered through magnifying glasses in the flickering glow of kerosene lamps. They tapped grinding wheels to distinguish sound, examined cartridge cases for microscopic marks, and recorded particle uniformity data — safeguarding wartime supplies and igniting the unyielding flame of China’s industrial spirit.
Eighty years later, in the laboratories of China National Machinery Industry Corporation (Sinomach), cutting-edge spectrometers and precision instruments quietly deliver elemental analysis with an impressive accuracy of 5 PPM (0.0005%). This advanced digital testing spans seven key sectors, including metals, ceramics, polymers, and composites, supporting China's high-tech industry development.
