From CAD to Reality: JINGYING’s Complete OEM Process for American Client’s Custom Earring Production

Executive Summary

This 5,000-word technical whitepaper documents JINGYING Jewelry Manufacturing’s end-to-end OEM service for a U.S.-based fashion brand’s custom earring collection. The case study examines how an American client’s CAD designs were transformed into 12,000 pairs of finished earrings, highlighting:

  • Cross-border design collaboration protocols

  • Technical adaptations for mass production

  • Quality assurance systems meeting U.S. market standards

  • Logistics solutions for trans-Pacific jewelry shipping

1. Project Initiation Phase

1.1 โปรไฟล์ลูกค้า

The Massachusetts-based client requested:

  • ผลิตภัณฑ์: 925 silver geometric drop earrings with cubic zirconia

  • ปริมาณ: 12,000 คู่ (4 color variants)

  • จัดส่ง: 3 shipments over 8 เดือน

  • การรับรอง: Must comply with California Proposition 65

1.2 CAD File Analysis

JINGYING’s engineering team identified 3 required modifications:

  1. Prong Thickness Adjustment (Original 0.3mm → Modified 0.5mm for durability)

  2. Hinge Mechanism Redesign (For easier assembly)

  3. การลดน้ำหนัก (From 8.2g to 6.5g per earring)

โต๊ะ: CAD Design vs. Production-Ready Comparison

Design Element Original CAD Modified Version Reason
การตั้งค่าหิน 4-ง่าม 6-ง่าม Security improvement
Post Length 7มม. 8มม. U.S. piercing standard
Surface Finish ด้าน Brushed Better scratch resistance

1.3 Compliance Documentation

  • Conducted RHOS testing for silver alloy

  • Prepared CPSIA tracking labels

  • Verified nickel content below 0.05%

2. Pre-Production Engineering

2.1 Rapid Prototyping Process

  • ผลิต 4 prototype versions using:

    • SLA 3D printing (For form verification)

    • การคัดเลือกนักแสดงที่หายไป (For metal samples)

    • Hand-fabricated samples (For mechanism testing)

Prototyping Timeline

3. Production Execution

3.1 Manufacturing Workflow

  1. Silver Casting

    • Used vacuum casting machines

    • สำเร็จแล้ว 92% material utilization rate

  2. Automated Polishing

    • Implemented robotic polishing arms

    • Reduced hand-polishing time by 65%

  3. Laser Stone Setting

    • Precision CZ placement with 0.1mm tolerance

    • 0.3% stone loss rate (Industry average: 1.2%)

3.2 Quality Control Metrics

  • ความแม่นยำมิติ: ± 0.15 มม.
