· Production Process Introduction

1. Design Validation & Engineering Optimization: Our professional engineering team works closely with you to review CAD drawings, optimize the design for CNC machinability, and verify thread fit, structural strength, and assembly compatibility for your specific application.
2. Raw Material Sourcing & Inspection: Premium brass bar stock is sourced from certified suppliers, with full spectrometric analysis conducted to ensure material composition, purity, and mechanical properties meet industry standards.
3. Precision CNC Machining: High-speed CNC lathes execute precision turning to form the stepped cylindrical geometry, followed by precision tapping for both axial and radial threaded holes. The anti-rotation flat surfaces are milled to exact dimensions for reliable anti-loosening performance.
4. Deburring & Finishing: All components undergo meticulous manual and mechanical deburring to ensure burr-free thread profiles, smooth edges, and no sharp corners that could damage mating parts during assembly.
5. Comprehensive Quality Inspection: 100% inspection is performed for every part, including thread verification with go/no-go gauges, dimensional measurement via CMM (Coordinate Measuring Machine), and visual inspection to ensure 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, sorted, and prepared for packaging in a controlled environment to prevent contamination and surface damage.

· Packaging and Shipping Methods

• Standard Packaging: Each component is individually wrapped in anti-scratch PE film, then placed in custom-cut EPE foam inserts to prevent movement and surface damage during transit. Bulk orders are packed in heavy-duty corrugated cartons with reinforced edges 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.
