OEM Coil Springs
High-performance OEM coil springs custom-engineered to match your exact application requirements. We manufacture precision compression coil springs for machinery, automotive, industrial equipment, and custom engineering projects, delivering reliable, long-lasting spring solutions for OEM and bulk buyers worldwide.
Our OEM Coil Spring Features & Advantages
✅ Fully Custom OEM Service We produce coil springs strictly following your drawings, samples, technical parameters including wire diameter, free height, inner/outer diameter, spring rate, and material grade. Whether you need small-batch prototype samples or large-volume mass production, we support flexible OEM orders.
✅ Premium Raw Materials We select high-quality spring steel materials to guarantee stable mechanical performance. Our coil springs maintain consistent spring rate under repeated compression and fatigue loads, resisting deformation and fracture during long-term continuous operation.
✅ Precision Manufacturing & Strict Quality Control Every coil spring is processed with advanced CNC coiling machines. All finished products undergo dimensional inspection, spring force testing, fatigue testing, and surface treatment checks. Each spring’s specifications are consistent with your OEM technical data sheet.
✅ Multiple Surface Treatment Options Surface finishing choices include zinc plating, powder coating, black oxide to provide anti-corrosion, rust-proof protection, adapting to humid, high-temperature and heavy-load working environments.
✅ Wide Application Range Our OEM coil springs are widely used in automotive assemblies, heavy machinery, agricultural equipment, valve systems, construction hardware, and other industrial fields.
✅ Reliable Bulk Supply & Efficient Logistics We have stable production capacity for large OEM orders. We support standard export packing and can provide packing list, commercial invoice and other export documents to match your international shipments.
