Stamping copper contacts

Stamping Copper Contacts

They are manufactured by stamping thin copper alloys such as brass, phosphor bronze, or beryllium copper. Below are the key characteristics that make them ideal for high-volume connector applications.

1. Super Fast and Cost-Effective

Produced via progressive die stamping, these contacts are extremely quick to manufacture, achieving rates of hundreds to over a thousand pieces per minute. This efficiency is perfect for massive production runs. Additionally, the use of continuous roll stock minimizes material waste, reducing overall costs.

2. Spot-On Precision

The molds are engineered for high accuracy, maintaining tight tolerances of approximately ±0.01 to ±0.03 mm. This ensures every piece is virtually identical, which is critical for tight-fitting connectors. The process can also handle intricate, miniature shapes such as micro-springs or ultra-thin bends with ease.

3. Lightweight with Great Contact

Stamped from thin metal, these contacts are lightweight and compact, enabling connector miniaturization. For female terminals, the stamping process naturally creates flexible spring structures that press firmly against male pins, ensuring low contact resistance and reliable electrical connectivity.

4. Excellent Material Properties

Copper alloys offer superior electrical and thermal conductivity, allowing them to handle high currents and high-frequency signals effortlessly. Materials like beryllium copper provide exceptional springiness and durability, withstanding repeated plugging and unplugging cycles without degradation.
