Custom Wave Springs & Multi-Layer Wave Spring Manufacturer
We design and manufacture high-performance custom wave springs. Our flat-wire coiling solutions deliver precise load control while reducing axial space by 50%—ideal for compact assemblies.
Custom Engineered Wave Springs for Critical OEM Industries
As a trusted wave spring manufacturer certified to IATF 16949 and ISO 13485, we supply single-layer wave springs, multi-layer wave springs (crest-to-crest), and nested wave springs. Our flat-wire coiling ensures strict load tolerances within ±5% while saving 50% axial space.
Compact crest-to-crest wave springs for cooling fans and optical transceivers, providing constant, low-profile axial preloading within micro-enclosures to dampen high-frequency rotor harmonics and prevent optical signal jitter.
Premium SUS17-7PH nested wave springs for traction motor bearings and dual-clutch transmissions, sustaining 1,000,000 micro-vibration cycles while compensating for thermal expansion.
Micro ribbon-wire wave springs down to fractional millimeter thickness in SUS316L, providing precise biasing force within +/-3% tolerance for surgical robotic wrist joints.
Multi-turn wave springs for harmonic drive gearboxes and robotic wrist joints, exerting uniform circumferential pressure to preload bearings and eliminate backlash.
Lightweight wave washers for drone folding wings and camera gimbals, delivering high spring rates at near-solid compressed heights with minimal weight penalty.
Heavy-gauge wave springs coated with Geomet or Dacromet to provide continuous axial sealing tension for solar tracker rotary joints and high-voltage contactors.
Superalloy Inconel X-750 or specialty spring steels wave springs for high-pressure mechanical face seals and pump valves, guaranteeing high-temperature creep resistance.

Frequently Asked Questions
We are a professional spring manufacturer with over 20 years of experience, located in Dongguan, China. We possess complete production lines, a heat treatment center, and an IATF16949 certified quality laboratory. You are welcome to visit our factory physically or via video call at any time.
We have extensive processing capabilities, covering a wire diameter range from 0.07mm to 25mm. We specialize in precision compression springs, extension springs, torsion springs, wire forms, as well as stamping parts and screws.
Absolutely. Our engineering team has over 30 years of experience. You can send us the sample, and we will reverse-engineer it using our imported Swiss precision instruments and generate CAD drawings for your approval. We can even assist in designing the spring based on your installation space.
Absolutely! We encourage sample requests to ensure our springs meet your exact requirements. If we have springs matching your specs in stock, we are happy to provide free samples (you may only need to cover shipping). For custom-designed springs,a nominal sampling/tooling fee applies, which is typically fully refundableonce mass production orders reach a certain volume.
We support flexible manufacturing. While large-volume production significantly reduces unit price, we also accept small trial orders (e.g., 100-500 pcs) to help you validate your market.
- Samples:As fast as3-5 daysfor standard springs.
- Mass Production:Typically10-15 days, depending on quantity and complexity.
We hold the IATF16949:2016 certification, the highest standard in the automotive industry, as well as ISO9001:2015 and ISO14001:2015. This ensures our products meet the stringent requirements of automotive, medical, and aerospace sectors.
We implement “Closed-Loop Quality Control.” Production is monitored by in-line inspection systems. Before shipment, products undergo rigorous testing using Japanese imported CCD fully automated inspection machines, image dimension measurement systems, and torque/load testers. Material certificates (COA) and inspection reports are provided with every shipment.
Quality is our cornerstone. Our in-house quality control lab utilizes precision measuring instruments(like optical projectors, force testers, salt spray test chambers) to rigorously inspect critical dimensions, load characteristics, fatigue life, material composition, and surface finishes. We adhere to strict quality standards and can provide test reports upon request.
For springs prone to tangling, we offer specialized packaging solutions such as Blister Trays, Tape & Reel, or Paper Tube packaging. This not only protects the product but also improves assembly efficiency on your automated production lines.
We support EXW, FOB, CIF, DDP, and more. With extensive export experience, we can ship goods directly to your designated port or warehouse.
