SUNZO sets industry benchmarks with uncompromising quality control spanning the entire product lifecycle, from raw material validation to end-of-line testing. Our commitment ensures each disc spring meets stringent international standards.

• Material Selection: Premium alloys including 65Mn, Inconel X-750, and 17-7 PH stainless steel with full traceability
• Material Verification: Spectroscopic analysis and mechanical property testing per ASTM E8 standards
• Precision Manufacturing: Advanced CNC coiling machines and precision stamping equipment maintaining dimensional tolerances of ±0.02mm
• In-Process Inspections: Ultrasonic flaw detection (ASTM E164) and load-deflection curve validation (ISO 16148)

Our disc springs are engineered for exceptional performance across demanding applications:

Finished products undergo rigorous environmental testing including salt spray exposure (ASTM B117) for corrosion resistance and thermal shock cycling for temperature stability.
