5G Base Station Surge Arrester Housing

Cold Extrusion & Precision CNC Machining

This precision-engineered aluminum housing is purpose-built for surge protection devices in 5G telecom base stations. Manufactured with a high-performance cold extrusion + CNC precision finishing process, it delivers outstanding strength, consistent dimensions, and reliable outdoor durability for critical communication infrastructure.

Product Highlights

  • Material: Premium AL6061‑T6/T651 aluminum alloy
  • Structure: One‑piece formed housing with high concentricity and structural rigidity
  • Surface: No secondary coating; strictly controlled surface finish, free of scratches, nicks, or burrs
  • Process: Cold extrusion + stress relief + precision CNC machining + deburring + inspection + clean packaging
  • Quality: Stable process capability and high repeatability for mass production
  • Application: Surge arrester enclosure for 5G base stations, outdoor telecom equipment, and lightning protection devices

Full Manufacturing Process

  1. Material Preparation
    High‑quality aluminum bar straightening, peeling, and precision cutting.
  2. Precision Cold Extrusion
    High‑pressure net‑shape forming at room temperature using custom precision tooling.
  3. Stress Relief Heat Treatment
    Eliminates internal stress, stabilizes dimensions, and prevents machining distortion.
  4. CNC Precision Machining
    Finishing of mating surfaces, mounting features, holes, and critical profiles.
  5. Deburring & Edge Breaking
    Full deburring and uniform edge breaking without dimensional damage.
  6. Surface Finishing & Cleaning
    Ensures smooth, consistent, defect‑free surfaces.
  7. Full Dimensional Inspection
    100% inspection of critical characteristics to meet strict quality standards.
  8. Clean Protective Packaging
    Packed in clean, protective containers for safe shipping and storage.

Key Manufacturing Challenges

  • Extrusion springback, wall thickness variation, and opening deformation affecting machining stock
  • High residual stress causing dimensional shift and distortion during CNC processing
  • Zero‑defect cosmetic requirement without protective coating
  • Deep cavities and complex edges making consistent deburring difficult
  • Strict process capability and batch stability for 5G telecom components
  • High strength, concentricity, and assembly precision for outdoor surge protection

Our Solutions

Precision Cold Extrusion Control

  • High‑precision long‑guide die design for improved concentricity
  • Optimized extrusion pressure, speed, and lubrication to reduce springback
  • Die pre‑compensation for stable dimensional consistency

Anti‑Distortion Control

  • Immediate post‑extrusion stress relief annealing
  • Separated roughing and finishing with layered cutting
  • Temperature‑controlled machining environment

Surface Quality Assurance

  • Mirror‑polished extrusion dies to minimize surface defects
  • High‑gloss aluminum‑specific cutting tools and optimized tool paths
  • Full‑process handling protection to prevent scratches and damage

Stable Batch Quality

  • Regular die maintenance, inspection, and replacement
  • First‑article, in‑process, and final inspection with SPC monitoring
  • Periodic equipment calibration for long‑term stability

Our Advantages

  • Specialized expertise in 5G telecom and surge arrester components
  • Cold extrusion + CNC hybrid process for higher strength, better consistency, and lower cost
  • Full‑process quality control meeting outdoor telecom reliability standards
  • Custom tooling and production based on 3D models or drawings
  • Clean, ready‑to‑assemble packaging for base station deployment
