Product Description
Dual-pitch Compression Springs | Precision Stainless Steel OEM Springs
Dual-pitch Compression Springs are specially designed helical compression springs with two different coil pitches in a single spring body. By combining a tighter coil section with a wider coil section, these springs provide progressive load characteristics, improved energy absorption, and optimized compression performance compared with conventional uniform-pitch compression springs.
METS specializes in manufacturing precision dual-pitch compression springs for OEM and industrial applications, using high-quality stainless steel, carbon steel, alloy steel, and other spring materials. Our advanced CNC spring coiling equipment, precision forming processes, and strict quality control ensure stable spring force, accurate dimensions, and reliable performance for demanding applications.
Dual-pitch compression springs are widely used where variable force, controlled deflection, vibration reduction, and space optimization are required. The unique pitch design allows the spring to respond differently under different compression stages, providing a softer initial load and increased resistance during further compression.
With flexible OEM/ODM capabilities, METS can customize wire diameter, spring outer diameter, free length, coil pitch, spring rate, end configuration, surface treatment, and material according to customer drawings or application requirements. Our springs are suitable for automotive components, industrial machinery, electrical equipment, medical devices, consumer products, and precision mechanical systems.
