A: It depends.If we have bulk goods in stock, we can ship goods within 3 days after the QC process. If we don’t have stock, normally it takes 7-15 days for OEM samples and 20-30 days for bulk goods. If it refers to opening the new mold, it takes an extra 7-15 days to make the mold.
Wave Spring Washers
Wave Spring Washers:
Materials:
- Stainless steel (AISI 302/304/316 for corrosion resistance), carbon steel (high-strength, heat-treated), alloy steel (high-temperature applications), or Inconel (extreme heat/corrosion resistance).
- Surface treatments: Passivation, zinc plating, or electropolishing for enhanced durability and reduced friction.
Manufacturing Process:
- Coil Winding: Precision winding of flat wire into multi-wave patterns.
- Heat Treatment: Stress-relieving or hardening (for steel) to optimize elasticity and load capacity.
- Grinding/Finishing: Achieve uniform height and smooth edges for consistent performance.
- Surface Treatment: Apply coatings or polishing to prevent corrosion and wear.
Key Production Considerations:
- Wave Consistency: Ensure uniform amplitude and wavelength for balanced load distribution.
- Height Control: Maintain precise free height to meet spring rate specifications.
- Edge Smoothing: Deburr edges to prevent stress concentrations and component damage.
- Material Fatigue Testing: Validate longevity under cyclic loading.
Applications:
- Automotive: Valve trains, transmissions, and suspension systems requiring compact springs.
- Aerospace: Actuators, landing gear, and avionics with space and weight constraints.
- Medical Devices: Surgical tools and implants needing biocompatible materials (e.g., 316L stainless steel).
- Industrial Machinery: Bearings, pumps, and seals in high-cycle environments.
- Electronics: Heat sinks, connectors, or micro-devices requiring minimal spring height.
Installation:
- Orientation: Align the wave peaks perpendicular to the load direction for optimal force distribution.
- Preload: Compress to 20–30% of free height to activate spring force without over-stressing.
- Torque Control: Follow manufacturer guidelines to avoid exceeding the washer’s elastic limit.
- Lubrication: Apply grease in high-cycle applications to reduce wear and noise.
Advantages:
- Space-Saving Design: Delivers high load capacity in minimal axial space.
- Vibration Damping: Absorbs shocks and compensates for thermal expansion.
- Customizable: Adjustable wave count, height, and material for specific load/deflection requirements.
Note:
- Avoid stacking multiple wave springs unless designed for combined use.
- Replace washers if permanent deformation or cracks are detected.
- Use in clean environments to prevent debris from affecting wave motion.
Frequently Asked Questions
A: Normally, we make a 30% deposit after Pl confirmation and a 70% balance before shipment. lf order amountis too small, we can also change to 100% deposit in order to save bank handling charge.
A: A pre-bulk sample check can solve this problem to the largest extent. We will arrange production according to the pre-bulk sample quality standard after your confirmation of the samples.
A: We are not only a trading company but also a manufacturer. Our factory mainly focuses on mold design and quality inspection. Our bulk production may come from the factories we have worked with for a long time, and they are all ISO9001 certified. Through this cooperation model, we can not only ensure product quality and service, but also satisfy the diversified product needs of customers, and the price is more advantageous.
A: Yes,we are very glad to offer you samples.
However the express courier cost from our company to your required address will be upon your account.
Usually we use DHL, UPS, FEDEX or EMS as the courier.
It will take 3-7 days to arrive many Europe countries and North America.
Which express courier we will use, it’s up to your convenient or the express charge.
