· Production Process Introduction

1. Design & DFM Validation: Our engineering team optimizes shaft length, diameter, and thread size via Design for Manufacturability (DFM) analysis to ensure maximum strength and installation ease.
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 long cylindrical body is precision-turned to achieve uniform OD and smooth surface finish.
   • Tapping: The internal threaded bore is precision-tapped to match standard thread sizes (M6/M8/M10, etc.).
   • Milling: A hexagonal flat section is milled into the end for tool-driven installation and torque transfer.
4. Surface Finishing: The shafts undergo brushing and passivation to enhance corrosion resistance and surface smoothness.
5. Quality Inspection: 100% dimensional inspection via CMM and thread gauge verifies OD, length, and thread accuracy, while a functional test ensures smooth tool engagement.
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 thread requirements.
• Rush Service: Expedited production (4–6 days for samples) is available upon request for urgent restocks.

Can you accommodate full custom modifications?

• Size & Length Customization: Custom overall length, outer diameter (OD), and step diameters to match your specific mechanical requirements.
• Thread Customization: Custom thread types (metric/imperial), pitch, and depth to meet your fastening needs.
• Feature Modifications: Custom flat section shapes (hexagonal/rectangular), additional mounting holes, or external threads for specialized integration.
• 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.
