Manufacturing Standards

• Certification: ISO 9001-Certified
• Key Processes: CNC Turning (stepped profile + flange) → Deburring → Surface Passivation → CMM Inspection
• Standard Parameters:
  • Flange Diameter: 18–25mm (customizable 12–30mm)
  • Stepped Body Diameters: 12mm / 10mm (optimized for component fit)
  • Overall Length: 20–35mm (customizable 15–50mm)
  • Dimensional Tolerance: ±0.01mm (ensures precise alignment with mating components)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-wear operation)

· Application Scenarios

• Industrial Automation: Robot arm joint positioning pins, conveyor system component guides, and sensor mounting locators.
• Tooling & Fixtures: Jig and fixture alignment pins, mold component locators, and inspection tool positioning pins.
• Medical & Laboratory Equipment: Diagnostic instrument alignment pins, sample handling system locators, and surgical device components.
• 3D Printing & CNC Machinery: 3D printer build plate alignment pins, CNC fixture locators, and tool changer positioning pins.
• Automotive & Marine: Engine component alignment pins, chassis assembly locators, and boat hardware positioning pins.

· Production Process Introduction

1. Raw Material Preparation: Cut certified 304 stainless steel round bars into blanks matching the pin’s overall length.
2. CNC Turning: Use high-precision CNC lathes to machine the multi-stepped profile and integrated flange in a single setup for maximum concentricity.
3. Deburring & Finishing: Remove sharp edges from the flange, stepped transitions, and pin ends to prevent component wear and ensure safe handling.
4. Surface Passivation: Apply a chemical passivation treatment to enhance 304 stainless steel’s natural corrosion resistance.
5. Quality Inspection: Perform CMM dimensional scanning, concentricity testing, and surface finish analysis to verify compliance with design specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Sealed in anti-scratch plastic bags and labeled with size specifications to prevent damage and ensure traceability.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents pin deformation, scratch damage, and mixing of sizes).
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 pieces for standard configurations; 200 pieces for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes CNC machining and passivation); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust flange diameter, stepped body sizes, overall length, or switch to 316 stainless steel for extreme corrosion environments. Our engineering team validates designs for alignment accuracy and load-bearing performance.
