Precision Stamping Capabilities

Tingfeng Hardware specializes in manufacturing precision metal springs and contacts, providing custom, high-reliability precision metal components for smart wearables and AI hardware. Utilizing high-speed precision stamping presses and multi-station progressive dies, we achieve stable stamping of ultra-thin materials down to 0.05mm.

Equipped with a comprehensive suite of advanced processing and inspection equipment, we maintain full in-house control over the entire workflow—from mold design to mass production—ensuring that our products comply with ISO 9001 and international environmental standards. With a daily production capacity exceeding 2 million units and new mold delivery lead time of just 5-7 days, we offer rapid responsiveness to meet the R&D and iteration demands of smart product development.

Product Overview

Precision spring sheets are critical components for reliable electrical connections in smart devices, widely used in TWS earbuds, smartwatches, and health monitoring devices. High-performance materials such as phosphor bronze and beryllium copper are utilized to ensure optimal performance.

Through precise die design and wire EDM processing, contact fingers are accurate and burr-free. Customizable gold/silver plated contacts meet high-cycle mating and low contact resistance requirements. Our professional mold team provides early DFM analysis, optimizing product structure, avoiding potential risks, and accelerating time-to-market for smart products.
