· Production Process Introduction

1. Design & DFM Validation: Our engineering team optimizes shaft length, flange dimensions, and hole position via Design for Manufacturability (DFM) analysis to ensure maximum load capacity and retention stability.
2. Material Preparation: Premium stainless steel bar stock is cut to size and faced to ensure a clean starting surface.
3. Precision CNC Machining:
   • Turning: The flanged head and cylindrical body are precision-turned to achieve uniform OD and smooth surface finish.
   • Drilling: A transverse mounting hole is drilled at the tip for cotter pin locking.
   • Chamfering: All edges are chamfered to eliminate sharp points and facilitate installation.
4. Surface Finishing: The shaft undergoes brushing and passivation to enhance corrosion resistance and surface smoothness.
5. Quality Inspection: 100% dimensional inspection via CMM and micrometer verifies OD, flange diameter, and hole position, while a functional check ensures smooth cotter pin insertion.
6. Final Packaging: Shafts are wrapped in anti-scratch film and secured in custom foam trays to prevent bending or scratching during transit.

· Packaging and Shipping Methods

• Standard Packaging: Each shaft is wrapped in anti-scratch PE film, placed in custom-cut EPE foam inserts inside a reinforced corrugated box, with additional bracing to prevent bending. For bulk orders, wooden pallets are used to secure multiple shafts.
• Shipping Options:
  • Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototype and small-batch orders (full tracking provided).
  • Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation support.
• Custom Packaging: Branded labeling, barcoding, and custom tray inserts are available to align with your independent store’s brand guidelines and inventory management needs.

· Frequently Asked Questions (FAQ)

What is your Minimum Order Quantity (MOQ)?

• Prototypes/Samples:1 piece available for custom design validation.
• Production Runs: Starting at 50+ pieces for standard configurations. We specialize in low-volume, high-precision custom fabrication to match your online store’s demand.

What are your typical lead times?

• Prototype/Sample Orders: 7–10 business days from final CAD design approval (includes machining and finishing).
• Mass Production: 15–25 business days, depending on order volume, shaft length, and custom feature requirements.
• Rush Service: Expedited production (4–6 days for samples) is available upon request for urgent restocks.

Can you accommodate full custom modifications?

• Size & Shape Customization: Custom overall length, outer diameter (OD), flange dimensions, and hole size to match your specific mechanical requirements.
• Feature Customization: Custom hole positions, groove designs, or threaded ends for specialized locking or mounting needs.
• Material Upgrades: Switch between 304 stainless steel (corrosion resistance) or 316L stainless steel (medical/high corrosion) based on your application.
• Surface Finish Options: Custom plating (zinc/nickel), anodizing, or black oxide for enhanced corrosion resistance or aesthetic appeal.
• Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
