We are a professional and reliable original source factory specializing in the production and export of high-quality coil springs for Auto Parts. With years of manufacturing and overseas export experience, we have built a complete industrial system covering raw material procurement, precision production, professional heat treatment, strict quality testing and standardized global export services, enabling us to provide stable, cost-effective and high-performance spring solutions for worldwide customers.
As a direct manufacturing factory, we completely eliminate intermediate links, which allows us to offer competitive factory-direct prices while ensuring stable product quality and sufficient supply capacity. Our factory is equipped with advanced CNC coiling equipment, automatic forming machines and professional heat treatment production lines. Every coil spring is produced with precise dimensional control, uniform material density and stable mechanical performance. Through standardized quenching and tempering treatment, our products obtain excellent toughness, strong compression resistance, outstanding fatigue resistance and long service life, perfectly adapting to harsh working conditions such as heavy load, high frequency vibration and long-term continuous operation.
We implement strict full-process quality inspection from raw material selection to finished product delivery. Each batch of coil springs undergoes professional tests for hardness, elasticity, compression tolerance and surface durability to ensure 100% compliance with export standards and customer technical requirements. We support OEM and ODM customized services, including custom sizes, wire diameters, surface treatments and special technical parameters according to customers’ drawings or samples.
With independent export qualification and mature overseas trade experience, we provide standardized packaging, professional document support and stable on-time delivery. Adhering to the principle of quality first, credit foremost and customer-oriented service, we have established long-term stable cooperative relationships with clients from Southeast Asia, Africa, the Middle East, Europe and other regions. We sincerely welcome global buyers to inquire, customize and establish long-term win-win cooperation.
