What transforms ordinary components into life-saving automotive horns? At our factory, each unit represents 37 quality checks and 20 years of acoustic engineering expertise.
Our vertically integrated manufacturing combines Japanese servo presses (0.01mm precision) with German torque calibration systems, producing 15,000 horns daily that meet 42 international safety standards.
Discover the three pillars of our manufacturing philosophy that ensures every horn performs flawlessly when lives depend on it.
Every beep starts here — with our skilled team and high-precision tools
Robots can't replace human expertise. Our 85 technicians average 7 years' experience specifically in automotive acoustic systems assembly and testing.
Each work station combines ergonomic tooling (3.6Nm calibrated drivers) with digital torque monitoring, achieving 99.92% fastening accuracy across 1.2 million monthly assemblies.

The heart of every vehicle's voice — your horn
Why do emergency responders trust our horns? The answer lies in components that outperform military specifications (MIL-STD-810G).
Vibration-resistant neodymium magnets (N52 grade) and oxygen-free copper coils maintain 125dB output after 15,000 humidity cycles (85°C/85%RH) - exceeding typical 5,000-cycle requirements.
