Production Process:
-
Material Selection & Blanking: Select high-conductivity brass alloy coils. The coil is fed into the progressive die for initial blanking to the required strip width.
-
Progressive Die Stamping & Forming: The brass strip progresses through die stations for precise piercing, bending, and forming into the final terminal shape in a single, high-speed operation.
-
Deburring & Cleaning: Stamped parts undergo tumbling or vibratory finishing to remove burrs and sharp edges, followed by ultrasonic cleaning to prepare for plating.
-
Precision Surface Plating: Terminals are plated via barrel or rack plating processes (e.g., tin, nickel, or gold) to ensure solderability, low contact resistance, and corrosion protection.
-
Quality Inspection & Testing: 100% visual inspection and sample-based testing for dimensions (CMM), plating thickness, and electrical conductivity/contact resistance.
-
Packaging: Components are packaged in anti-oxidation materials, wound on reels for auto-assembly, or packed in labeled boxes for shipment.
Surface Treatments:
-
Electro-Tin Plating: Provides excellent solderability and good corrosion resistance at a cost-effective price point for standard battery connections.
-
Nickel Plating: Offers superior surface hardness, wear resistance, and a stable base for subsequent plating, ideal for high-cycle mating applications.
-
Selective Gold Plating: Applied to critical contact points for ultra-low and stable contact resistance, excellent corrosion resistance, and long-term reliability in premium applications.
-
Passivation (for specific alloys): Enhances the natural corrosion resistance of the brass substrate, often used prior to plating for improved adhesion and performance.
Factory Show:
Our dedicated metal stamping facility features high-speed precision progressive stamping presses (40 to 250-ton) equipped with automatic feeders and in-line vision inspection systems for consistent, high-volume output of brass components. We maintain an in-house tool & die shop with CNC wire EDM for precision die manufacturing. A dedicated plating line handles various finishes critical for electrical components. Rigorous quality control is enforced using measurement systems like optical comparators and X-ray coating thickness gauges, ensuring every terminal meets the stringent conductivity and reliability standards required for battery and power equipment.
