FAQ

1. What information do you need to provide a quote or start customization?
To provide an accurate quote and begin production, we typically require the following:

• Detailed Engineering Drawings: Including diameter, length, tolerances, and any special geometric features.

• Material Specification: Your preferred stainless steel grade (e.g., 304, 316, 17-4PH). We can also advise on the best material for your application.

• Hardness & Heat Treatment Requirements: Required surface and core hardness.

• Quantity: The estimated annual usage or order quantity.

• Surface Finish: Any specific surface treatment needs.

2. What are the advantages of your stainless steel pins compared to standard carbon steel pins?
Our stainless steel pins offer three key advantages:

• Superior Corrosion Resistance: Essential for excavators operating in wet, salty, or chemically aggressive environments, significantly reducing rust and pitting.

• Excellent Wear Resistance: Provides a longer service life, even under abrasive conditions, leading to reduced downtime and maintenance costs.

• High Strength-to-Weight Ratio: Offers great strength without unnecessary weight, and maintains integrity under heavy loads.

3. Do you provide complete OEM support and can you match our existing parts?
Absolutely. We specialize in OEM customization. We can manufacture pins to your exact specifications and replicate existing parts precisely. Simply send us a sample or a detailed drawing for a perfect match.

4. What is your typical lead time for custom orders?
Lead time depends on the order complexity and quantity. For standard custom orders, it's generally 15-30 days. We always provide a confirmed lead time after order confirmation and strive to meet urgent requirements whenever possible.

5. How do you ensure the quality and durability of your cylindrical pins?
Our quality is ensured through a multi-step process:

• Raw Material Control: Sourcing from certified mills.

• Precision Machining: Using CNC turning and grinding.

• Heat Treatment: Strictly controlled processes to achieve desired hardness and toughness.

• Rigorous Inspection: Final inspection includes dimensional checks, hardness testing, and surface finish evaluation.

6. What is the minimum order quantity (MOQ) for customized pins?
We offer flexible MOQs to support both large-scale OEMs and smaller projects. Please contact us with your requirements, and we will do our best to accommodate your needs.

7. Can you provide different surface treatments besides the standard polished finish?
Yes. In addition to the standard precision ground finish, we offer various surface treatments such as Passivation (for enhanced corrosion resistance), Chrome Plating (for extreme wear resistance), and Powder Coating (for added protection and color coding).

8. What kind of certifications does your manufacturing process hold?
Our production facility is certified under ISO 9001:2015 for Quality Management Systems. We can also provide material certificates and full traceability for our products upon request.
