1. DefinitionPrecision hardware refers to customized metal components with tight dimensional tolerances ranging from 0.001 mm to 0.05 mm, far higher precision than regular hardware parts. Ordinary hardware has a tolerance over 0.1 mm with burrs and uneven surfaces, while precision hardware features smooth finish, zero burrs and consistent dimensions, widely used as core supporting parts for high-end industries instead of end consumer goods.
2. Common Raw Materials
- Brass & Phosphor Bronze: Excellent electrical conductivity, mainly for connector terminals, pins and charging pile fittings.
- Stainless Steel (304/316L): Outstanding rust & corrosion resistance. 316L medical grade is applied to surgical implants, auto fasteners.
- Aluminum Alloy: Lightweight and good heat dissipation, ideal for camera brackets, new energy heat sinks and drone components.
- Special Alloys (Titanium, Nitinol): High strength and biocompatible for aerospace parts and minimally invasive medical devices.
3. Main Processing Technologies① CNC Milling & TurningAdopts 5-axis CNC equipment for irregular curved and multi-hole parts with ±0.002mm tolerance, suitable for small-batch complex non-standard parts such as optical bases and motor housings. ② High-speed Precision Stamping800–1200 stamping cycles per minute for mass production of ultra-thin shrapnels, SIM card trays and battery connectors, minimum workpiece thickness down to 0.1mm. ③ Swiss-type Lathe MachiningProcess tiny shafts, miniature screws and contact pins (0.5–20mm diameter), widely used in watch movements and micro motor spindles. Post-process: Electroplating, polishing and passivation to improve corrosion resistance, conductivity and wear resistance.
4. Core Application Fields
- Consumer Electronics & 5G: Camera brackets, RF connectors, TWS earphone spring sheets, ultra-mini components for smartphones.
- New Energy & Automobile: Sensor housings, new energy vehicle copper busbars and wiring terminals, certified by IATF16949 to withstand extreme temperature from -40℃ to 120℃.
- Medical Devices: Puncture needles, orthopedic screws and minimally invasive surgical tools with micron-level precision complying with ISO13485.
- Aerospace & Automation: Aerospace valve cores, robot bearings and precision gears, critical for domestic high-end equipment manufacturing.
5. Daily ScenariosPrecision hardware can be found in watch gears, laptop hinges, electric toothbrush motor shafts and smart wearable internal parts, invisible but indispensable for normal equipment operation. |
