New Energy Spring Solutions
Specialized elastic components for electric vehicles, battery packs, utility energy storage, solar tracking dampers, and wind power generation.
New Energy & Clean Tech Spring Requirements
The accelerated transition to electrification requires springs engineered for higher thermal ceilings, harsh chemical electrolyte environments, non-magnetic criteria, and multi-decade outdoor weatherability. TOSTA delivers custom springs with precision tolerances, superior electrical conductivity options (beryllium copper, silver plating), and long fatigue endurance under continuous cycling.
Typical Applications
EV Drive Motor Bearing Preload Springs
Single and multi-turn wave springs eliminating motor bearing end-play and minimizing high-frequency NVH acoustic resonance.
Battery Pack Module Expansion Springs
Precision compression and Belleville springs maintaining constant cell preloading throughout electrochemical charge-discharge swelling.
EV Charging Port & Gun Latch Springs
Corrosion-resistant stainless steel latch springs rated for over 10,000 rapid plug insertion/extraction cycles.
Battery Energy Storage System (BESS) Springs
Heavy-duty structural isolation and busbar contact springs protected with C5-M marine-grade anti-corrosion coatings.
Solar Tracking System Damper Springs
High-endurance outdoor compression and torsion springs damping wind buffet loads across utility-scale single-axis trackers.
Wind Turbine Pitch & Braking Springs
High-tonnage disc and helical spring packs for hydraulic pitch control and emergency fail-safe rotor brakes.
