1. By Manufacturing Process
Wave springs are made by either coiling or stamping.-
Coiling: Wire or strip is coiled and heat-treated. It offers clean edges and design flexibility, ideal for small-batch, high-precision applications (e.g. aerospace, medical devices).
-
Stamping: Flat wire or sheet is stamped into shape, then formed into rings. It is cost-effective and suited for large-volume production (e.g. automotive, valves).
2. By Structure
-
Multi-Turn Types
-
Series Type (Opposed-Wound): Single strip wound in sequence, available in flat or closed ends. Offers uniform load and compact size.
-
Nested Type (Parallel-Wound): Layers wound concentrically for higher load capacity without stacking.
Single-Turn Types (Wave Washers)
-
Gap Type: C-shaped, flexible under compression, good for preload and damping.
-
Overlap Type: Ends overlap to prevent over-compression; stronger and more durable.
-
Closed Type: O-shaped with high load and short travel; made by stamping and forming.
3. By Application
-
Bearings: Provide preload, reduce noise, and extend service life.
-
Electronics: Used as battery contacts or connectors with good elasticity and conductivity.
-
Seals: Maintain sealing force and prevent leakage in pumps and compressors.
-
Automotive: Found in suspensions, transmissions, and engines for cushioning and stability.
