· Production Process Introduction

1. Design & DFM Validation: Our engineering team optimizes shaft length, spline profile, and tip geometry via Design for Manufacturability (DFM) analysis to ensure maximum torque capacity and alignment precision.
2. Material Preparation: Premium stainless steel bar stock is cut to size and faced to create a clean starting surface for machining.
3. Precision CNC Machining:
   • Turning: The long cylindrical body and rounded tip are precision-turned to achieve tight concentricity and a smooth finish.
   • Spline Hobbing: The splined end is precision-hobbed to match standard spline profiles (straight/involute).
   • Chamfering: All sharp edges are chamfered to prevent injury and improve installation.
4. Surface Finishing: The shaft undergoes brushing and passivation to enhance corrosion resistance and surface durability.
5. Quality Inspection: 100% dimensional inspection via CMM verifies OD, spline pitch, and length; a functional torque test ensures reliable power transfer.
6. Final Packaging: Each shaft is wrapped in anti-scratch film and secured in a custom foam tray to prevent bending or scratching during transit.

· Packaging and Shipping Methods

• Standard Packaging: Each shaft is wrapped in anti-scratch PE film, placed in a custom-cut EPE foam insert inside a reinforced corrugated box, with additional bracing to prevent bending. Bulk orders are secured on wooden pallets with plastic wrapping.
• 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: 10–15 business days from final CAD design approval (includes machining and finishing).
• Mass Production: 20–30 business days, depending on order volume, shaft length, and custom spline requirements.
• Rush Service: Expedited production (7–10 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), and tip dimensions to match your specific application.
• Spline Customization: Custom spline type (straight/involute), module, tooth count, and length to meet your torque transfer requirements.
• Material Upgrades: Switch between 304 stainless steel (corrosion resistance) or alloy steel (high torque) based on your application.
• Surface Finish Options: Custom plating (zinc/nickel), black oxide, or passivation for enhanced durability or aesthetic appeal.
• Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
