With over 15 years of specialized experience, we deliver mission-critical components that meet the most stringent technical requirements of these demanding sectors.
Exceptional Mechanical Properties
  • Tensile strength exceeding 1800 MPa
  • Fatigue life exceeding 10⁶ cycles
  • Operating temperature ranges from -270°C to 650°C
Material Science Expertise
Aerospace Applications
Inconel 718 (UNS N07718) with superior creep resistance for jet engine actuators and landing gear systems, while 17-7 PH stainless steel (AISI 631) provides exceptional corrosion resistance for satellite deployment mechanisms.
Precision Machinery Applications
50CrVA alloy springs maintain 98% load retention after 10,000 compression cycles, critical for CNC machine tool spindles and robotic arm joints. All materials comply with ASTM F2328 and AMS 5662 specifications, with full material traceability via EN 10204 3.1 certification.
Advanced Manufacturing Capabilities
  • CNC precision stamping with ±0.01mm dimensional tolerance
  • Automated heat treatment processes (vacuum quenching and tempering)
  • Advanced surface treatments: electroless nickel plating (5-15μm thickness), passivation (per ASTM A967), and PTFE coating for extreme chemical resistance
  • In-line laser inspection for geometric verification
These processes enable us to produce disc springs ranging from 6mm to 200mm outer diameter, with custom configurations available for unique load-deflection requirements.
