SUNZO Mechanical Zinc-Plated Disc Spring: Engineered Wear-Resistant Solutions for Heavy-Duty Industrial Environments
In industrial environments characterized by extreme friction, mechanical stress, and corrosive elements, SUNZO Mechanical Zinc-Plated Disc Springs deliver superior durability through advanced surface engineering and material science.
Advanced Zinc Plating Technology
The proprietary mechanical zinc plating process utilizes a high-pressure tumbling technique with zinc alloy micro-particles (85% Zn, 15% Al) applied at 40-60 MPa, creating a uniform 8-12μm coating with a hardness of 250-300 HV.
This achieves 300% improvement in wear resistance compared to uncoated springs (per ASTM G99 pin-on-disk testing) and provides 1,000+ hours of corrosion protection in salt spray environments (ASTM B117).
Premium Material Construction
Material Type Key Properties Application Benefits
65Mn Alloy Tensile strength: 1,200-1,400 MPa
Yield strength: ≥900 MPa		 Excels in high-cycle applications (10⁶+ cycles at 70% load)
60Si2MnA Elastic modulus: 206 GPa
Fatigue limit: 450 MPa		 Superior shock absorption for impact-loading scenarios
Design & Performance Characteristics
Conical design (dish height-to-thickness ratio 0.7-1.1) enables variable stiffness profiles (10-45 N/mm) through precision stacking configurations:
  • Parallel stacks for high-load applications (up to 30 kN)
  • Series stacks for enhanced deflection (up to 15mm)
  • Nested combinations offering adaptive performance in dynamic loading systems
Key Industrial Applications
  • Steel Manufacturing: Roll mill bearings utilizing zinc-plated springs to withstand rolling contact fatigue and cooling fluid corrosion
  • Construction Equipment: Hydraulic breaker systems with 60Si2MnA springs delivering 50,000+ impact cycles before maintenance
  • Mining Machinery: Conveyor belt tensioners employing parallel-stacked 65Mn springs for consistent preload under dust and moisture exposure
  • Oil & Gas: Wellhead control valves using zinc-aluminum plated springs to resist H₂S and brine corrosion
Quality Assurance & Testing
Each spring undergoes rigorous quality validation including:
  • Coating adhesion testing per ISO 2409 (cross-cut method, rating 0)
  • Load-deflection verification to ISO 16148 (±2% force tolerance)
  • Metallurgical inspection via SEM to ensure coating uniformity and absence of micro-cracks
  • Full material traceability from raw steel lot to final plating certification (EN 10204 3.1)
Available Options
SUNZO offers both standard DIN 2092/2093 sizes and custom-engineered solutions, with plating options including trivalent passivation for enhanced corrosion resistance and PTFE topcoats for low-friction applications.
