Product Description
Custom Stamped Contact Shrapnel – Precision Metal Parts for IoT Sensors & Smart Home Devices
Tingfeng Hardware provides custom stamped contact shrapnel specifically engineered for IoT sensors and smart home devices. Using premium materials including phosphor bronze, stainless steel, and beryllium copper, our components are manufactured through precision stamping and bending processes to deliver reliable performance in critical applications.
Product Overview
Our contact shrapnel addresses the comprehensive requirements of IoT and smart home devices for component miniaturization, reliability, and cost-effectiveness. We utilize phosphor bronze for high conductivity and elasticity, or stainless steel for superior strength and corrosion resistance. Through precision stamping technology, we achieve consistent contact geometries and stable elastic force for optimal performance.
Product applications include sensor signal transmission contacts, battery connection springs, and device interconnect terminals. Gold or nickel plating ensures low contact resistance (≤10mΩ) and long-term oxidation resistance. Each shrapnel undergoes 100% dimensional inspection and force testing, making them suitable for smart door sensors, temperature/humidity sensors, smart plugs, security cameras, and various IoT devices.

We bought stamped brackets for an industrial cabinet. Nothing fancy. Delivery was on time, packaging was sturdy, and all 500 pieces were within drawing tolerances. One small complaint: the surface had some light scratching, but it’s for indoor use so not a big deal. Would order again for non-cosmetic parts.

Needed a fine blanked connector part with zero burr on the shear edge. Other vendors quoted high tooling cost. Tingfeng‘s tooling was 20% less expensive, and the sample parts arrived with clean edges – no secondary deburring needed. We’ve placed a production order for 5,000 pieces. So far, so good.

Used them for a deep drawn stainless steel part that we previously imported from Italy with long lead times. The quality is comparable, and the price was about 12% lower. Delivery took 18 days instead of 15, but they informed me proactively. Good enough for a trial order. Will see how mass production goes.
