The alliance spirit originated from the national Great Third Front Construction period (1964–1980s), inheriting decades of industrial experience, adhering to strict machining standards and craftsmanship. We provide reliable mechanical manufacturing and precision machining services to global industry.
GTFI offers a complete range of electric motors – from heavy‑duty industrial motors (0.75‑500kW, IE3/IE4) to precision micro motors for consumer electronics, robotics, and automation. Our portfolio includes DC brushed, geared, vibration, coreless, brushless, and stepper motors, all manufactured with high‑grade materials (pure copper windings, epoxy resin rotors, and corrosion‑resistant coatings).
Whether you need a powerful motor for pumps, fans, and conveyors, or a compact, quiet motor for smart locks, drones, and beauty devices, GTFI delivers reliable performance, long service life, and full compliance with international standards.
