· Production Process Introduction

1. Design Validation & Optimization: Our engineering team reviews your CAD files, verifies thread tolerance compatibility, and optimizes the design for CNC machinability and structural integrity.
2. Raw Material Sourcing & Inspection: Premium stainless steel bar stock is sourced from certified suppliers and inspected via spectrometric analysis to ensure material purity and mechanical compliance.
3. CNC Precision Turning: High-speed CNC lathes machine the stepped cylindrical geometry, shoulder features, and prepare the blank for threading and drilling.
4. Specialized Secondary Operations: Thread rolling (for superior thread strength vs. cutting) and deep-hole drilling are performed to create the precision external threads and hollow inner bore.
5. Surface Treatment & Finishing: All pins undergo passivation to remove free iron and enhance corrosion resistance; deburring and cleaning ensure burr-free surfaces and dimensional accuracy.
6. Comprehensive Quality Inspection: 100% inspection via CMM (Coordinate Measuring Machine) and thread gauges verifies all critical dimensions; tensile and corrosion resistance testing is conducted for batch validation.
7. Cleanroom Packaging Preparation: Pins are cleaned in a controlled environment and prepared for packaging to prevent contamination.

· Packaging and Shipping Methods

• Packaging: Each pin is individually wrapped in anti-scratch PE film and sorted by size in EPE foam trays to prevent tangling and damage. Bulk orders are packed in sturdy anti-static corrugated cartons; medical/aerospace-grade orders include vacuum-sealed packaging and cleanroom certification.
• Shipping Options:
  • Express Delivery (3-7 Business Days): DHL, FedEx, or UPS for prototypes, small batches, or urgent orders (full tracking and delivery confirmation provided).
  • Standard Shipping (25-40 Business Days): Sea freight for mass production orders (FCL/LCL options available, with full customs documentation support).
• Custom Packaging: Branded labeling, barcoding, serialized part marking, and custom foam inserts are available to align with your inventory management and branding requirements.

· Frequently Asked Questions (FAQ)

What is your Minimum Order Quantity (MOQ)?

What are your typical lead times?

• Prototyping: 5-10 business days (from CAD finalization to shipping).
• Production: 12-25 business days (varies by order volume, material selection, and surface treatment requirements).
• Rush Service: Expedited production (3-5 days for prototypes) is available upon request for an additional fee.

Can you accommodate custom modifications?

• Material Customization: Titanium, brass, or alloy steel for specialized strength, weight, or conductivity requirements.
• Design Modifications: Custom thread sizes (metric/imperial), overall lengths, shoulder dimensions, solid bore options, or added keyways/set screw holes.
• Finish Options: Electropolishing, nickel plating, or PTFE coating for enhanced lubricity and chemical resistance.
• Branding & Marking: Laser engraving of part numbers, logos, or serial numbers for traceability.
