Custom Precision Metal Stamping, Deep Drawn Enclosures & CNC Sheet Metal from Nanpi Hub
High-precision progressive die stamping, deep drawn motor casings, electronic shielding cans, and bracket assemblies from Nanpi, the Hardware Stamping Capital of China.
1688 Source Factory Cost vs Global Wholesale Price Estimated Profit Margin: 70% - 85%
Engineering Overview & Manufacturing Capabilities
Nanpi County is officially designated as China's Hardware Stamping Capital, with a four-decade history of manufacturing electronic shielding cans, automotive stamping brackets, deep-drawn battery cases, and aerospace terminal hardware. The cluster houses over 3,000 stamping enterprises, specialized progressive die tooling shops, and modern electroplating parks.
Our stamping facilities operate 45-ton to 500-ton high-speed progressive mechanical and hydraulic stamping presses capable of cycling up to 800 strokes per minute. We handle materials including stainless steel (301/304/316), beryllium copper, brass, phosphor bronze, cold-rolled steel (SPCC), and aluminum alloys with tolerances down to ±0.01 mm.
From prototype tooling (wire-EDM) to high-volume multi-million piece automated production runs with automated optical sorting, Nanpi provides world-class engineering capabilities at true source-factory 1688 cost levels.
Industrial Cluster Deep Dive & Supply Chain Edge
Nanpi County (南皮县), Cangzhou
The Hardware Stamping & Deep Drawing Capital of ChinaLocalized Ecosystem: In Nanpi, precision die mold design (CAD/CAM), slow-wire EDM cutting, continuous strip raw material coil warehouses, heat treatment, and surface plating (tin, nickel, zinc, silver, gold) are located within minutes of each other.
The "Neijuan" Source Factory Edge: Nanpi's toolmakers build high-speed progressive dies at one-fourth the cost of European or North American mold shops. Once tooling is validated, parts run at pennies per piece, saving buyers 50% to 75% on precision metal components.

End-to-End Production & Quality Control Process
Raw Strip Slitting & Coil Inspection
Raw stainless steel, copper, or steel coils undergo thickness verification (±0.005mm), hardness testing (Rockwell/Vickers), and metallurgical analysis.
Progressive Stamping & Deep Drawing
High-speed progressive dies perform blanking, piercing, bending, coining, and deep drawing in continuous synchronized strokes up to 600 SPM.
Centrifugal Deburring & Ultrasonic Degreasing
Stamped parts undergo centrifugal barrel tumbling to eliminate micro-burrs, followed by multi-stage ultrasonic solvent degreasing.
Continuous Electroplating / Surface Treatment
Parts receive continuous barrel plating: tin, bright nickel, zinc-nickel alloy, or gold plating with strict salt-spray anti-corrosion control.
Automated Optical Sorting & Tape-and-Reel Packaging
Vision cameras inspect 100% of parts for critical dimensions. Parts are packed into carrier tape on reels, vacuum blister trays, or bulk cartons.
