· Production Process Introduction

1. Design & Engineering Optimization: Our professional engineering team collaborates with you to review CAD drawings, optimize coaxiality and machinability, and validate mechanical and conductive performance requirements for your specific application.
2. Raw Material Preparation & Inspection: Premium brass bar stock is sourced from certified suppliers, with full spectrometric analysis conducted to verify material composition, purity, and mechanical properties meet industry standards.
3. Precision CNC Turning: High-precision CNC lathes execute one-piece turning to form the multi-segment stepped structure, ensuring strict control of coaxiality and dimensional accuracy throughout the process.
4. Finishing & Deburring: Critical surfaces undergo centerless grinding or mirror polishing to achieve the required surface finish, followed by meticulous manual and mechanical deburring to ensure burr-free edges and scratch-free surfaces.
5. Comprehensive Quality Inspection: 100% full inspection is performed for every part, including dimensional verification via CMM (Coordinate Measuring Machine), coaxiality testing, and fit check with precision gauges to ensure full compliance with all specifications.
6. Optional Surface Treatment: Custom surface treatments such as passivation, electroless nickel plating, or tin plating are applied as required to enhance corrosion resistance, wear performance, or electrical conductivity.
7. Final Packaging Preparation: Components are cleaned, anti-tarnish treated, and prepared for packaging in a controlled environment to prevent surface oxidation and damage.

· Packaging and Shipping Methods

• Standard Packaging: Each component is individually wrapped in anti-tarnish PE film, then secured in custom-cut EPE foam inserts to prevent collision, scratching, and surface oxidation during transit. Bulk orders are packed in heavy-duty corrugated cartons with reinforced edges, with additional cushioning for maximum protection.
• Shipping Options:
  • Express Delivery (3-7 Business Days): DHL, FedEx, or UPS for prototypes, small batch orders, or urgent requirements, with full tracking and delivery confirmation provided.
  • Standard Sea Freight (25-40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation and logistics support included.
• Custom Packaging Solutions: We offer fully customizable packaging, including branded labeling, barcoding, serialized part marking, and custom foam inserts to align with your inventory management and brand guidelines.
