Every horn that leaves our factory carries the precision of engineering and the passion for perfect sound. At FHL GBSY JS-TECH, we've transformed horn manufacturing into an exact science.
Our 15,000 sqm facility combines automated precision with artisan craftsmanship, producing over 2 million horns annually that meet 23 international quality certifications - each unit undergoes 17 quality checks before shipment.
Discover how we turn raw materials into life-saving acoustic warnings through our meticulous production philosophy.
Strict Processes Create Every Reliable Speaker
Precision manufacturing begins with uncompromising standards. Our 72-step production protocol ensures every horn performs flawlessly in extreme conditions.
From CNC-machined brass diaphragms to military-grade epoxy coatings, each component follows exacting specifications - our vibration-resistant designs withstand 50,000+ activation cycles without degradation in sound quality.
