For ten years, Lispring has been focusing on the R&D and production of wave springs and spiral retaining rings in the past, present and future, aiming to provide reliable and satisfactory products to global high-tech customers. We welcome your inquiries at any time.
When you think about aerospace engineering, the first things that probably come to mind are jet engines, satellites, or maybe even the sleek wings of a commercial airliner. But hidden inside these marvels of technology are small parts that make a huge difference. One of those unsung heroes is the wave spring.
At their core, wave springs are compact, coiled metal rings with a wave–like pattern. Unlike bulky coil springs, they compress more efficiently, saving up to 50% of axial space. For aerospace engineers, this space–saving design is a game–changer. It means more room for critical systems without compromising strength or performance.
Every ounce on an aircraft translates to higher fuel burn. By replacing traditional springs with wave springs, engineers cut down on material usage while maintaining the same–or even better–functionality. Less weight means better fuel efficiency, longer range, and reduced emissions.
Aerospace demands materials that can take the heat–literally. Wave springs are often made from high–performance alloys like Inconel, Elgiloy, or stainless steel. These materials handle extreme temperatures, corrosive environments, and high stress without losing their shape or force.
Vibrations are the enemy of precision. In aircraft and spacecraft, even minor vibrations can affect performance or safety. Wave springs absorb and manage these vibrations, protecting sensitive components like avionics or communication systems.
From the intense pressures inside a jet engine to the vacuum of space, wave springs deliver consistent force. Their design ensures they don't lose load under compression, which makes them a reliable choice in the most demanding conditions.
Today's aerospace trend leans toward making systems smaller, lighter, and more powerful. Wave springs perfectly support this push toward miniaturization. Their compact design frees up space and allows engineers to pack more performance into tighter assemblies.
Who would've thought that behind Tianwen 1's smooth landing on Mars, there are two types of "special shock absorption springs" from Lispring? These two "little heroes" have clear specs: one is about 8 cm in diameter, the other about 6 cm, with 8 of each installed on the lander—just the right number to form a "stability team".
Don't be fooled by their ordinary looks, their performance is truly tough. Made of special alloy, each spring can withstand 30 to 45 Newtons of force when compressed by 10 mm, leaving traditional coil springs far behind. What's even more impressive is that they can handle high temperatures up to 800°C, perfectly meeting the "lightweighting and compactification" demands of aerospace. Their fatigue resistance is also maxed out.
For engineers chasing high performance without compromise, wave springs are not just an option–they're the future.
