· Production Process Introduction

1. Design Validation: Our engineering team reviews your CAD files, optimizes for CNC machinability, and verifies tolerance stack-ups for your application.
2. Raw Material Selection: Premium aluminum alloy bar stock is sourced and inspected via spectrometric analysis to ensure material purity and mechanical compliance.
3. CNC Turning: High-speed CNC lathes machine the external stepped geometry, face surfaces, and prepare the internal bore for broaching.
4. Precision Broaching: Specialized broaching equipment cuts the internal hexagonal profile to exact dimensions, ensuring perfect shaft mating.
5. Surface Treatment: Components undergo hard anodizing in a controlled black finish to enhance hardness, corrosion resistance, and wear performance.
6. Quality Control: 100% inspection via CMM (Coordinate Measuring Machine) and optical comparators verifies all critical dimensions; functional testing ensures torque resistance.
7. Final Preparation: Deburring, cleaning, and anti-static packaging to meet industrial assembly standards.

· Packaging and Shipping Methods

• Packaging: Each bushing is individually wrapped in anti-scratch PE film and placed in EPE foam inserts to prevent movement during transit. Bulk orders are packed in sturdy corrugated cartons with custom foam liners; anti-static packaging is available for electronic applications.
• Shipping Options:
  • Express (3-7 Business Days): DHL, FedEx, or UPS for prototypes, small batches, or urgent orders (full tracking provided).
  • Standard (25-40 Business Days): Sea freight for mass production orders (FCL/LCL options available, with customs documentation support).
• Custom Packaging: Branded labeling, barcoding, and serialized part marking are available to align with your inventory and branding requirements.
