Tight Tolerance Precision Stamping - ±0.02mm Accuracy Guarantee
Tingfeng Hardware guarantees ±0.02mm tolerance on critical dimensions, meeting stringent requirements of AI infrastructure and robotics for precision hardware. Our manufacturing process utilizes high-precision wire EDM dies, CNC ground punches, and imported high-speed presses with die thermal balance control, ensuring dimensional stability in mass production.
We implement full-process SPC monitoring with CPK ≥1.33 and provide complete dimension inspection reports, safeguarding core components of smart products.
The limit of precision stamping lies in the comprehensive accuracy of die and equipment. We have introduced Japanese AIDA high-speed presses and German die machining centers, with stamping speeds up to 800 SPM while maintaining ±2μm repeat positioning accuracy in dynamic state.
Our dies use high-strength powder metallurgy steel, vacuum heat-treated to HRC62-64 for excellent wear resistance. For thin material stamping, we've developed micro-clearance die technology with clearance controlled at 3%-5% of material thickness, significantly reducing burr and rollover. CMM sampling reports are provided for each batch with traceable dimensions.
