Detailed description

Custom Multi-Layer Stacked Wave Springs

As a professional custom spring manufacturer based in Dongguan, we supply precision multi-layer stacked wave springs for global industrial customers. These slotted stacked wave compression springs are assembled by stacking multiple wave washers, delivering large axial compression force within limited installation space. All stacked wave springs can be customized strictly according to customers’ 2D drawings, 3D models and physical samples. Thanks to compact size, uniform load output and good fatigue resistance, stacked wave springs are widely used in automation equipment, precision bearings, valve assemblies, sealing structures, gear devices and other compact mechanical systems requiring preloading, shock absorption and clearance compensation. We provide full OEM & ODM customization services to satisfy different space constraints and load requirements of worldwide industrial purchasers.

CNC Precision Manufacturing Technology for Stacked Wave Springs

Custom multi-layer stacked wave springs are produced through precision stamping, wave forming and professional stacking assembly. Raw material strips are stamped into single wave washers, then shaped to stable waveform, followed by high-temperature stress relief heat treatment to eliminate internal stress and maintain consistent elastic performance during long-term compression cycles. Subsequent deburring and flatness calibration remove sharp edges to avoid scratching mating parts during assembly.
Our production line can manufacture stacked wave springs, single-turn wave springs, flat wire torsion springs, compression springs and various special-shaped elastic components, supporting one-stop procurement of metal springs and stamping hardware.

Product Features & Industrial Advantages of Multi-Layer Stacked Wave Springs

Multi-layer stacked wave springs adopt multi-piece superimposed structure, realizing high spring force under low installation height. Their core strengths for industrial applications are listed below:
Ultra-compact structure: Compared with conventional coil compression springs, stacked wave springs occupy less axial space under equivalent load;
Stable and uniform axial load: Consistent waveform ensures smooth force output during repeated compression;
Excellent fatigue resistance: Standard heat treatment process effectively prevents elastic attenuation under continuous cyclic work;
Flexible structural configuration: Number of layers, thickness, waveform height and outer/inner diameter can be adjusted freely to match assembly space;
Multiple material and surface treatment options: Carbon spring steel for general working conditions and stainless steel or high-temperature alloy for corrosion-resistant and high-temperature environments.
Unstable load force, uneven waveform or inconsistent stacking height will lead to assembly clearance and premature equipment failure. High-precision custom stacked wave springs are essential to guarantee reliable operation of your precision machinery.

Our One-Stop Custom Manufacturing Solutions

We support full-parameter customization of multi-layer stacked wave springs, serving automation manufacturers, precision machinery factories, valve and sealing enterprises as well as engineering clients globally.
Our product portfolio covers miniature stacked wave springs, medium-load multi-layer wave springs, heavy-duty alloy wave springs, alongside non-standard wave springs developed for special equipment.
Every stacked wave spring undergoes stamping, forming, heat treatment, stacking calibration and customized surface treatment. All technical indicators can be adjusted in accordance with your specifications. Besides wave springs, we can provide matching torsion springs, disc springs, wire forming parts and precision stamping components to simplify your procurement and assembly workflow.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all custom spring orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample dimension, force value and performance, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

Q: What surface finishing options do you provide for custom springs and elastic parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: zinc plating, nickel plating, black oxide, passivation, powder coating, electrophoresis, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the tolerance and quality of custom industrial springs?
A: Our standard wire diameter tolerance for general springs is ±0.01mm, with spring force value tolerance controlled within ±5%. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension & force testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.

FAQ 6

Q: What types of springs and elastic components do you support customization for?
A: We cover full-category custom elastic hardware, including compression springs, torsion springs, extension springs, wave springs, flat springs, spring clips, shrapnel, custom wire forming parts and various non-standard elastic stampings. No matter conventional standard springs or special-shaped custom elastic parts, we can provide targeted manufacturing solutions.
