· Production Process Introduction

1. Design & DFM Validation: Our engineering team optimizes step dimensions, thread size, and flange position via Design for Manufacturability (DFM) analysis to ensure maximum load capacity and installation ease.
2. Material Preparation: Premium carbon steel bar stock is cut to size and faced to ensure a clean starting surface.
3. Precision CNC Machining:
   • Turning: The stepped profile and integrated flange are precision-turned to achieve uniform OD and smooth surface finish.
   • Threading: The left-end thread is precision-rolled to match standard thread sizes (M6/M8/M10, etc.).
   • Milling: A flat slot is milled into the right-end tip for tool-driven installation or locking.
4. Surface Finishing: The component undergoes zinc plating to provide anti-rust protection and a durable metallic finish.
5. Quality Inspection: 100% dimensional inspection via CMM and thread gauge verifies OD, step height, and thread accuracy, while a functional check ensures smooth tool engagement.
6. Final Packaging: Components are wrapped in anti-scratch film and packed in corrugated cartons to prevent scratching during transit.

· Packaging and Shipping Methods

• Standard Packaging: Each component is wrapped in anti-scratch PE film and packed in a corrugated carton. Bulk orders are secured on wooden pallets with plastic wrapping to prevent damage during long-distance transit.
• 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 100+ 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, component size, 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 & Shape Customization: Custom overall length, outer diameter (OD), step heights, and flange dimensions to match your specific mechanical requirements.
• Feature Customization: Custom thread types (metric/imperial), slot shapes (flat/hex), or additional features (e.g., grooves, notches) for easy integration.
• Material Upgrades: Switch between carbon steel (cost-effective) or 304 stainless steel (corrosion resistance) based on your application.
• Surface Finish Options: Custom zinc plating colors, black oxide, or passivation 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.
