· Product Overview

· Core Specifications

Material Performance

• 304 Stainless Steel
  • Tensile Strength: ≥515 MPa (rigid for high-precision positioning and load support)
  • Corrosion Resistance: Passed 72-hour salt spray test (ideal for humid/industrial environments)
  • Food-Safe: Compliant with FDA 21 CFR 175.300 (suitable for food-processing equipment)
  • Hardness: 150–180 HV (balanced rigidity and ductility for repeated assembly)

Manufacturing Standards

• Certification: ISO 9001-Certified
• Key Processes: CNC Turning (multi-stepped profile + rounded head) → Deburring → Surface Passivation → CMM Inspection
• Standard Parameters (for set of 5):
  • Diameter Range: 4–10mm (customizable 2–15mm)
  • Length Range: 20–50mm (customizable 15–80mm)
  • Dimensional Tolerance: ±0.01mm (ensures precise mating with alignment holes and fixtures)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-wear operation)

· Application Scenarios

• Industrial Automation: Robot arm joint alignment pins, conveyor system component locators, and sensor mounting guides.
• Tooling & Fixtures: Mold and die alignment pins, CNC fixture locating pins, 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 tool changer locators, and extruder system guides.
• 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 and diameter.
2. CNC Turning: Use high-precision CNC lathes to machine the multi-stepped profile and smooth rounded head in a single setup for maximum concentricity.
3. Deburring & Finishing: Remove sharp edges from steps, rounded heads, and pin ends to prevent workpiece damage 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 Sets (5 pieces): Wrapped in anti-scratch foam padding, sealed in moisture-proof plastic bags, and labeled with size specifications for 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)

• Lead Time: Standard lead time is 7–30 working days (includes CNC machining, passivation, and inspection); expedited production (5–7 days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust diameter/length, step geometry, head shape (flat/rounded), or switch to 316 stainless steel for extreme corrosion environments. Our engineering team validates designs for alignment accuracy and load-bearing performance.
