Automotive coil spring
Wuxi Dongting Xinqiang Spring Factory produces automotive coil springs designed for brake system applications, where consistent force and fatigue resistance are critical. The springs are customizable in material and dimensions to meet specific OEM or aftermarket requirements, with industrial-grade quality ensuring reliability under cyclic loading. These components are engineered to maintain their elastic properties over millions of compression cycles, a key factor in vehicle safety.
Coil springs for brake systems are typically manufactured from high-carbon steel (e.g., SAE 1070, 1090) or alloy steels (e.g., 60Si2Mn, 51CrV4) for enhanced strength and durability. Standard wire diameters range from 3 mm to 16 mm, with load capacities and free lengths tailored to the vehicle model. Wuxi Dongting Xinqiang Spring Factory’s offerings align with these typical industry parameters, and buyers can specify custom designs for their applications.
Automotive manufacturers, repair shops, and parts distributors source these springs for brake assemblies, suspension systems, or clutch mechanisms. Buyers must confirm the spring rate (N/mm), free length, and wire diameter to ensure compatibility with their vehicle’s brake caliper or suspension geometry. The factory is located in Wuxi, Jiangsu Province, China, and can support bulk orders with flexible packaging and shipment options.
| Material | Customizable high-carbon or alloy steel |
| Typical Material Grades | SAE 1070, 1090, 60Si2Mn, or 51CrV4 (standard for brake springs) |
| Wire Diameter | 3 mm to 16 mm (typical range for automotive coil springs) |
| Free Length | Customizable per application (standard: 50 mm to 300 mm) |
| Spring Rate | 10 N/mm to 100 N/mm (typical for brake systems) |
| Load Capacity | 500 N to 5000 N (typical range, dependent on design) |
| Surface Treatment | Zinc plating or powder coating (standard for corrosion resistance) |
| Fatigue Life | 1,000,000+ cycles (typical for automotive-grade springs) |
| Operating Temperature | -40°C to 120°C (standard for brake applications) |
| End Type | Closed and ground, open, or hooked (customizable) |
Wuxi Dongting Xinqiang Spring Factory is located at No.86, Chunsun East Road, Dongting Town, Wuxi, Jiangsu Province, China. The company specialises in the production of coil springs for automotive applications, including brake systems, suspension, and clutch mechanisms. Its profile indicates a focus on customisable solutions, with the ability to tailor material, dimensions, and surface treatments to customer specifications.
The supplier’s trust tier is classified as harbor, and its response metrics are currently unrecorded, suggesting limited recent activity. Wuxi Dongting Xinqiang Spring Factory does not explicitly state certifications such as ISO/TS 16949 or IATF 16949, which are common in the automotive industry. Buyers are advised to request quality documentation, such as material certificates and fatigue test reports, to verify compliance with their requirements.

Sourcing Automotive Coil Spring from Wuxi Dongting Xinqiang Spring Factory - China Import Guide
Before placing an order with Wuxi Dongting Xinqiang Spring Factory, confirm the spring’s material grade, wire diameter, and surface treatment to ensure compatibility with your brake system or suspension design. Request a prototype or sample for physical testing, including load-deflection tests and fatigue cycling, to validate performance under real-world conditions. Verify whether the factory can provide third-party test reports for critical parameters like spring rate and corrosion resistance.
Logistics for bulk orders should be coordinated with the factory’s location in Wuxi, China. Specify your preferred Incoterms (e.g., FOB Shanghai or CIF to your port) and packaging requirements, such as individual poly bags or bulk palletizing. Lead times may vary depending on customisation, so clarify production schedules and shipping modes (air, sea, or rail) to align with your inventory needs.
For quality control, insist on pre-shipment inspections covering dimensional accuracy (wire diameter, free length, coil diameter), material composition (spectrometry), and surface treatment integrity (salt spray test for corrosion resistance). Request documentation such as the MTC, fatigue test reports, and packing lists to ensure traceability. For brake system applications, confirm that the springs meet or exceed OEM specifications for load capacity and durability.
