· Production Process Introduction

1. Design & DFM Validation: Our engineering team optimizes pin dimensions, knurl pattern, and tip geometry via Design for Manufacturability (DFM) analysis to ensure maximum grip strength 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 cylindrical body and protruding tip are precision-turned to achieve tight OD tolerances and a smooth middle section.
   • Knurling: The dual-section knurled pattern is precision-machined to enhance manual grip.
   • Chamfering: All sharp edges are chamfered to prevent injury and improve handling.
4. Surface Finishing: The pins undergo brushing and passivation to enhance corrosion resistance and surface durability.
5. Quality Inspection: 100% dimensional inspection via CMM verifies OD, tip diameter, and length; a functional grip test ensures secure manual handling.
6. Final Packaging: Pins are sorted by size and packed in anti-static bags inside corrugated cartons to prevent scratching or misplacement during transit.

· Packaging and Shipping Methods

• Standard Packaging: Pins are sorted by specification and packed in anti-static PE bags, placed in labeled corrugated cartons. 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 compartment trays 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, pin size, and custom knurl pattern 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), and tip dimensions to match your specific application.
• Knurl Pattern Customization: Custom knurl type (straight/diamond), pitch, and coverage area to meet your grip requirements.
• Material Upgrades: Switch between 304 stainless steel (general corrosion resistance) or 316L stainless steel (medical/high corrosion environments) based on your application.
• Surface Finish Options: Custom plating (zinc/nickel), anodizing, or black oxide for enhanced durability or aesthetic appeal.
• Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
