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.

Conical Spherical Washers: Overview
Materials:
- Stainless steel (AISI 304/316 for corrosion resistance), carbon steel (high strength, heat-treated), or alloy steel (heavy-duty applications).
- Optional coatings: Zinc plating, phosphating, or Dacromet for enhanced durability and rust prevention.
Manufacturing Process:
- Forging/Cold Forming: Shapes conical and spherical surfaces under high pressure for structural integrity.
- Machining: Precision grinding or CNC lathe work to achieve exact angular tolerances.
- Heat Treatment: Hardening and tempering (for carbon/alloy steels) to improve wear resistance.
- Surface Finishing: Polishing or coating to reduce friction and prevent galling.
Key Production Considerations:
- Dimensional Accuracy: Critical for conical and spherical profiles to ensure proper alignment and load distribution.
- Surface Smoothness: Minimize surface roughness to prevent stress concentration and wear.
- Heat Treatment Control: Avoid warping during hardening to maintain geometric consistency.
Applications:
- Machinery: Compensate for misalignment in bolted joints (e.g., flanges, bearing housings).
- Automotive: Suspension systems, engine mounts, or chassis components.
- Construction: Structural steel connections under dynamic loads.
- Aerospace: Vibration damping in high-stress assemblies.
Installation:
- Orientation: Place the conical face against the nut/bolt head and the spherical face against the mating surface.
- Alignment: Rotate the washer slightly during tightening to allow self-adjustment to angular offsets.
- Torque Control: Follow manufacturer guidelines to avoid over-compression, which may deform the washer.
Advantages:
- Eliminates stress concentrations caused by misaligned fasteners.
- Reduces vibration-induced loosening in dynamic systems.
- Extends service life of bolted joints by distributing loads evenly.
Note: Avoid reuse in critical applications if deformation or surface damage is observed. Pair with locknuts or threadlockers in high-vibration environments.
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.
