INDUSTRIES SERVED: Automotive Die Manufacturing , Industrial machinery, Marine
We specialize in manufacturing polyurethane springs (also called urethane spring, PU spring) to fit applications where traditional steel wire springs do not work well. Urethane springs outperform steel springs in load-bearing, with no risk of shattering. They're non-marring, oil-resistant, and have high dielectric strength. What's more, they operate quietly and have excellent shock absorption.
These springs are idely used in many applications. Urethane die springs have proven to be safest, most efficient and reliable compression material for punching, stamping and drawing dies. In electronics, they're great for devices sensitive to magnetism. And in industrial machinery, they play a key role in reducing vibration and noise.
| Customization Parameter | Specifications | Target Equipment/Industries |
|---|---|---|
| Hardness (Durometer) | 40A (flexible) to 95A (rigid) | Automotive punching, stamping and drawing dies manufacturing; Suspension bushing |
| Size & Shape | Machined, flat or custom-molded; up to 36" in length | Locomotive suspensions system |
| Specific polyurethane properties | Oil-resistant, UV-stabilized, food-grade | Provide comfort and pressure dispersion in furniture and sports equipment ,spring and shock absorbers |
| Load Capacity | 50 lbs to 5,000 lbs static load | Elevators, and escalators |
- Automotive : They are widely used in punching, stamping and drawing dies manufacturing; . They are also used as automotive bushings to enhance comfort .
- Industrial & Manufacturing: Use as key components for die-casting, stamping, and punching operations, compression performance ensures long service life. they are also applied in shock absorbers and various vibration-dampening scenarios .
- Transportation & Elevators: Counting on reliable performance and the capacity to withstand continuous mechanical stress, urethane springs are suitable for locomotive suspensions, elevators, and escalators, guaranteeing the safe operation of these high-frequency-use devices.
- Furniture & Bedding: Used in furniture, mattresses, and beds, they not only disperse pressure and boost comfort but also provide durable, body-conforming support to improve product user experience.
- Construction: Integrated into buildings and bridges, they absorb vibrations from external sources like earthquakes and wind, effectively enhancing the structures’ earthquake resistance.
- Agriculture: Applied to heavy machinery and equipment in the agricultural sector, they serve as durable, shock-absorbing components to protect equipment and ensure smooth farming operations.
- Extend life span and easy to replace: Urethane springs outlasts traditional metal springs significantly as it can provide superior wear , impact and oil resistance to wear, reducing frequent replacement needs.
- Shock absorption: They stand out in absorbing impacts and vibrations, making them a perfect fit for high-stress, high-impact application scenarios.
- High load-carrying capability: Compared to metal springs of the same size, urethane springs handle heavier loads.
- Non-Magnetic Property: This advantage offers great benefits for specific electronic or specialized applications .
- Flexible Customization: Urethane springs can be custom-made with tailored hardness, size, and shape to meet the unique requirements of various applications.
- Techincal support . Based on operating conditions, sizes and working load, we can guide customers to choose the right urethane durometer and formulations .
- Large stock of urethane spring can assure fast delvery.
- Various types, such as heavy duty, lightly duty, economical , solid Type, through hole type spring
- Quality inspection for each urethane spring (hardness, dimension and defects)
- No or low tooling cost
- Low MOQ and fast turnaround, and backed by 20+ years of expertise in polyurethane springs.
