Automotive Springs Manufacturer for Custom Vehicle Applications
Engineered springs for doors, latches, seats, pedals, and motion systems — built for durability, consistency, and scalable production.
Where Automotive Springs Are Commonly Used
Door & Closure Systems
Extension springs → door return & assist
Torsion springs → hinges, latch mechanisms
Seat & Interior Mechanisms
Compression springs → seat adjustment & damping
Flat spiral springs → cable balancing systems
Pedal & Control Systems
Extension / compression springs → brake & clutch return
High-cycle fatigue design required
Cable & Motion Systems
Constant force / flat spiral springs
Stable force over long stroke
Common Challenges in Automotive Spring Applications
High cycle fatigue under repeated motion
Limited installation space with strict tolerance
Noise, vibration, and inconsistent force
Surface corrosion from humidity, salt spray, or oil exposure
Performance variation in mass production
