Product Description
Sunzo Custom Disc Spring Solutions
Sunzo's custom disc spring solutions with high load-density capabilities are designed for extreme operating environments in industries such as nuclear power, aviation, and new energy applications.
In today's sophisticated industrial landscape, conventional standardized elastic components often struggle to meet complex challenges such as space constraints, ultra-high loads, high-temperature corrosion, or high-frequency dynamic fatigue. Standardized products can no longer satisfy enterprises' deeper demands for efficiency, safety, and digital transformation.
As a leading technology-driven enterprise in China's elastic component sector, Jiangsu Sunzo Spring Technology Co., Ltd. (Sunzo Spring/SUNZO) consistently pioneers industry innovation. Leveraging robust R&D capabilities and comprehensive manufacturing expertise across the entire industrial chain, the company focuses on delivering high-end customized disc spring solutions tailored for precise application scenarios worldwide.
Core Approach: Scenario-Driven Custom Solutions
Digital Simulation and Precise Collaborative Design
Sunzo Spring has established a dedicated product research and development center in Nanjing, Jiangsu Province. Our technical team integrates client-provided boundary conditions (installation space constraints, pre-tensioning requirements, working stroke, ambient temperature, and medium environment) and employs advanced finite element analysis (FEA) software along with our self-developed spring design system for digital modeling.
By simulating the nonlinear mechanical characteristics and stress distribution of disc springs in single-unit or combined stacking configurations, we can accurately predict product service life and load curves prior to manufacturing, thereby eliminating design uncertainties.
Full Industrial Chain Customization Capability
From selecting high-quality raw materials to developing proprietary key process equipment and achieving precision manufacturing, Sunzo Spring has established a complete closed-loop industrial chain at its modern production base spanning 60 mu (approximately 4 hectares) in Sihong, Suqian, Jiangsu Province. The company delivers products swiftly without minimum order quantity (MOQ) restrictions.
Industry Applications and Scenarios
Jiangsu Sunzo's custom-made disc springs feature exceptional load-bearing density and versatile configuration capabilities, making them widely used in critical sectors vital to the national economy and advanced manufacturing.
| Industry | Application Scenarios | Core Requirements Addressed |
|---|---|---|
| Nuclear power and aviation | Key valves for nuclear power plant reactors, aerospace actuation systems, buffer devices for equipment | Extreme safety requirements, long service life stability, complex dynamic fatigue challenges |
| Oil and Natural Gas (Underground Drilling) | Underground shockers, measurement tools for real-time drilling (MWD), high-temperature and high-pressure valve seals | Absorbs intense axial vibrations, maintains high load capacity under extreme high temperature and strong corrosion conditions |
| Ultra-high voltage power transmission | Busbar connections for power transmission equipment; High-voltage circuit breaker mechanisms; Bolted electrical connection points | Compensation for differential thermal expansion, prevents bolt creep and loosening, eliminates safety hazards from poor contact |
| Heavy Metal Processing and New Energy Technologies | Main air valve of blast furnaces; locking systems for steelmaking rolling mills; yaw and braking systems for wind turbines; pre-tensioning mechanisms for hydrogen fuel cell stacks | Provides sustained constant closing pressure or braking preload under high-frequency vibration, prolonged high temperatures, or extreme climate conditions |
| Petrochemical and Industrial Valves | Ball valves, control valves, globe valves, pipeline flange gasket locking mechanisms | Addresses valve seat leakage caused by chemical corrosion and thermal expansion/contraction, ensuring leak-free sealing performance |
