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 Lock Washer
Conical Spring Lock Washer
Material:
- Spring steel (e.g., 65Mn, 70Cr) or stainless steel (AISI 304/316) for high elasticity and strength.
- Surface treatments: Zinc plating, phosphating, or galvanization for corrosion resistance.
Manufacturing Process:
- Stamping/Punching: Cut and form metal sheets into conical shapes.
- Heat Treatment: Quenching and tempering to achieve elasticity and hardness (HRC 40–50).
- Surface Coating: Apply anti-corrosion layers via electroplating or chemical treatment.
- Deburring: Smooth edges to prevent damage during installation.
Key Processing Points:
- Precise taper angle and thickness for consistent spring action.
- Uniform elasticity to maintain locking force under vibration.
- Avoid material brittleness during heat treatment.
Applications:
- Prevents loosening of bolts, nuts, and threaded fasteners in high-vibration environments.
- Used in automotive, heavy machinery, and construction equipment.
- Ideal for applications requiring high axial tension and vibration resistance.
Installation:
- Place the washer tapered side toward the nut/bolt head to maximize tension.
- Tighten the fastener to compress the washer and generate axial spring force.
- Avoid over-torquing to prevent permanent deformation.
Standards: Complies with DIN 6796, ISO 10673, and ANSI B18.21.1, depending on type and region.
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.
