Custom Zinc Die Casting for F-Type RF Connector Components

This project highlights our capabilities in zinc alloy die casting for producing compact, high-precision parts used in the RF (Radio Frequency) industry. The component shown is the zinc die-cast part of an F-type coaxial connector, commonly used in cable TV, satellite, and broadband internet applications.

From Design to Delivery : Our Zinc Die Casting Journey

🔍Client Requirement

The client required a custom zinc alloy body for an F Connector with the following specs:

  • High dimensional accuracy

  • Clean internal threading or precise openings

  • Excellent surface conductivity

  • Corrosion resistance for long-term outdoor use

  • Cost-effective for mass production

🛠️Challenges

  • Very small size with detailed threading and tight tolerances

  • Requirements for high-volume consistency

  • Surface finish needed to meet both functional and cosmetic standards

✅ Our Solution

  • Material: Zamak 3 Zinc Alloy

  • Process: High-precision hot-chamber die casting

  • Mold Design: Optimized for uniform metal flow and minimal shrinkage

  • Post-processing: Shot blasting and chromate treatment to enhance corrosion resistance

  • Inspection: 100% dimensional check for threading accuracy

🧲Results

  • Achieved production of over 50,000 units/month

  • <0.3% defect rate

  • Threads fit precisely with matching coaxial nuts

  • Clients reported excellent field performance and ease of assembly
