High-speed Rail Connector Metal Stamping Die

Product Overview

Developed exclusively for high-speed rail transit electrical connector terminals, this stamping mold can withstand the long-term fatigue stamping of copper alloy conductive sheets. We add a multi-stage buffer structure inside the mold to avoid terminal spring-back after stamping, a common defect in rail electrical parts. The mold surface adopts vacuum ion plating to resist oxidation under high-temperature continuous operation. Our factory has supplied stamping molds for multiple rail transit supporting manufacturers, optimizing the mold structure to ensure terminal conductivity stability after thousands of stamping cycles. Each finished mold undergoes 72-hour continuous load testing before delivery to guarantee rail-grade reliability.
