Polyurethane Springs Manufacturer – Durable Urethane Springs for Industrial Applications
As a leading polyurethane products manufacturer, we supply Polyurethane Springs, Urethane Springs, and Compression Springs designed for high-performance industrial applications. Our springs deliver outstanding wear resistance, shock absorption, and reliability—ideal for dies, presses, and heavy machinery.
Looking for Polyurethane Springs or Urethane Compression Springs that meet your exact specifications? Contact us today for customized polyurethane molding solutions and bulk orders from China’s trusted manufacturer.
Polyurethane springs are elastic components molded from PU elastomer. They compress and rebound like metal or rubber springs but deliver superior abrasion resistance, energy absorption, and long fatigue life. They store and release mechanical energy through elastic deformation.
Choose polyurethane springs when you need: quieter operation, better wear and chemical resistance, high-cycle fatigue life, or safer failure modes (no sharp shards). Use them where shock/vibration damping and reduced maintenance are priorities. For extremely high static structural loads, steel may still be required.
We supply compression springs, tubular (tube) springs, die springs (for stamping/press tooling), mold springs, vibration/shock springs, and custom hollow or thick-walled spring shapes. All are available in a range of Shore hardnesses and geometries.
Provide: required free height, compressed height, inner/outer diameter (or cross-section), target load/deflection curve (N/mm or lbf/in), desired Shore hardness, operating temperature range, expected cycle count, and any chemical/environmental exposure. A drawing or sample speeds quoting.
Typical hardnesses range from ~70A to 95A (Shore A) for elastomer springs; specialty formulations go higher or into Shore D. Standard temperature range is about −40°C to +80°C; high-temp polyurethane compounds can operate up to ~120°C.
