Product Description Product Description Strip Wave Spring Washers are precision-engineered elastic components made from flat strip material, designed with a wavy or corrugated profile. They provide a space-saving, load-bearing solution in axial load applications where compression and flexibility are required.Unlike traditional coil springs, these washers are formed by stamping or rolling flat metal strips into a wave-like shape, which allows for a compact design with excellent deflection and force output. Their thin, lightweight construction and predictable load characteristics make them ideal for applications with limited axial space.

Below is the typical process: 1. Raw Material SelectionChoose high-quality strip materials such as Stainless Steel 304, 316, 316L, 17-7PH (631), 65Mn, etc.Inspect for surface quality, thickness tolerance, and chemical composition compliance. 2. Blanking / CuttingCut flat wire or strip material to the required width and length.Maintain dimensional accuracy and smooth edges to avoid cracking during coiling. 3. Coiling / Wave FormingForm the strip into a multi-wave shape using specialized wave coiling machines or stamping dies.Maintain wave height, pitch, and number of turns as per design. 4. Stress Relieving / Heat TreatmentHeat treat to eliminate internal stress from forming and improve elasticity and fatigue resistance.Temperature and time are controlled based on the material type (e.g., 480-520°C for stainless steel). 5. Surface Treatment (Optional)Apply surface finishes such as degreasing, passivation, black oxide coating, or plating if needed.Improve corrosion resistance and cleanliness. 6. Cleaning & DeburringUltrasonic cleaning or tumbling to remove oil, dust, and burrs from previous operations.Ensure safe handling and long-term reliability. 7. Dimensional & Performance InspectionMeasure critical dimensions: free height, outer/inner diameter, wave height, etc.Conduct load testing under specified compression to verify spring force and deflection characteristics. 8. Final Treatment (if required)Apply additional processes like polishing, shot peening, or laser marking if specified by the customer. 9. PackagingPack springs in protective plastic bags, then place in carton boxes and palletize if needed.Label with batch number, part number, and customer details for traceability. 10. ShippingDelivered via air/sea/express logistics based on customer preference, ensuring secure and moisture-proof transit.Our quality control To guarantee that each wave spring meets performance and dimensional standards, a systematic quality control process is implemented throughout all production stages. 1. Incoming Material InspectionMaterial Certification Review: Verify chemical composition and mechanical properties from supplier mill certificates.Dimensional Check: Inspect thickness, width, and flatness of strip material.Surface Condition: Check for rust, burrs, cracks, or other surface defects. 2. In-Process Quality ControlEach production stage includes process-level inspection to ensure compliance with specifications.a. Blanking / CuttingLength and width tolerance checkEdge burr inspectionb. Wave Forming / CoilingWave height, pitch, and number of turns measured with gauges or optical measurement toolsSpring geometry visually and dimensionally inspectedc. Heat TreatmentFurnace temperature and duration monitoringHardness testing (e.g., Rockwell or Vickers)Microstructure analysis if needed for critical applicationsd. Surface TreatmentVisual inspection for coating uniformityAdhesion test or thickness measurement (e.g., plating or passivation) 3. Final InspectionBefore packing, every batch undergoes a comprehensive final quality check.Dimensional Inspection:Outer diameter (OD), inner diameter (ID), free heightWave amplitude, pitch, and number of wavesPerformance Testing:Load-Deflection Test: Use compression test machines to confirm force under specific loadFatigue Life Test: Simulate long-term cycles (optional for high-demand applications)Spring Rate Verification: Confirm consistency of spring stiffness (k)Visual & Surface Inspection:Surface defects, contamination, or discolorationCleanliness check before packaging 4. Sampling & Statistical Process Control (SPC)Sampling based on AQL standards (e.g., ISO 2859 or MIL-STD-105E)Use of control charts and capability studies (Cp, Cpk) to monitor key parameters 5. Traceability & DocumentationEvery batch is labeled and logged with traceability codesInspection records, heat treatment reports, and material certificates are archived for quality tracking 6. Packing InspectionVerify correct quantities, proper packaging (plastic bag → box → pallet)Moisture-proof and damage-resistant measures confirmed Optional Third-Party InspectionProvided upon customer request (e.g., SGS, BV, TUV) Goal:To deliver wave springs with stable mechanical properties, consistent dimensional tolerance, and reliable long-term performance in demanding applications.
