Precision Stamping & Mold Solutions for New Energy Battery Hardware: Poles, Electrode Sheets, Cover Plates

At Precision Works Plus, we specialize in custom stamping and mold solutions tailored for new energy battery hardware. With years of hands-on experience in serving battery manufacturers worldwide, we understand the unique challenges of producing these critical components—and we’re here to deliver the precision, efficiency, and scalability your production line needs.

Why Precision Stamping & Molds Matter for Battery Hardware

Battery hardware operates in extreme conditions: high current loads, temperature fluctuations (-40°C to 85°C), and corrosive electrolyte environments. Even minor deviations in dimension or surface quality can lead to catastrophic failures—reduced energy density, shortened cycle life, or safety hazards like short circuits.

Stamping stands out as the most cost-effective, high-volume manufacturing method for battery hardware, but only with molds engineered for the task:

Tight Tolerances: Electrode sheets (6-20μm thick) require ±0.5μm thickness control; pole and cover plate features demand ±0.01mm precision to ensure sealing and fit.
Material Compatibility: Processing ultra-thin copper/aluminum foils, high-strength aluminum alloys, and corrosion-resistant stainless steel without wrinkling, tearing, or material degradation.
Consistency at Scale: Producing 100,000+ components per day with uniform quality—critical for battery module/pack assembly.
Cost Efficiency: Stamping reduces per-unit costs by 30-40% compared to machining or etching, while molds with 500,000+ cycle lifespans lower long-term production costs.

Our Specialized Solutions for Core Battery Hardware

We don’t just build molds—we engineer end-to-end stamping solutions aligned with the unique requirements of each battery component:

1. Electrode Sheet (Current Collector) Stamping & Molds

Electrode sheets (copper foil for anodes, aluminum foil for cathodes) are the “energy transmission network” of batteries, requiring extreme thinness, flatness, and minimal burrs.

Mold Expertise: Custom dies for slitting, punching, and forming ultra-thin foils (6-20μm). Hardened steel (S136, H13) molds with PVD coatings ensure wear resistance and 500,000+ cycles.
Stamping Capabilities: Precision slitting (width 20-200mm) with burrs <5μm; round/rectangular punching for cylindrical/prismatic cells; surface-protective processes to avoid foil damage.
Key Advantages: Ensures uniform thickness for consistent active material coating; flatness control (<0.1mm/m) prevents short circuits in cell stacking.

2. Pole (Terminal) Stamping & Mold Solutions

Poles demand low contact resistance, hermetic sealing, and structural integrity—all dependent on precision stamping and mold design.

Mold Customization: Dies for flat, threaded, or cylindrical pole designs, integrated with insulation gasket grooves and welding preparation features.
Material Mastery: Stamping solutions for copper (nickel-plated), aluminum, stainless steel, and titanium alloy poles. Molds optimized to prevent springback and preserve surface plating.
Quality Assurance: In-die sensors monitor forming pressure and dimension; post-stamping deburring ensures contact resistance <5mΩ—critical for high-current performance.

3. Cover Plate Stamping & Integrated Mold Systems

Cover plates are the “safety shield” of batteries, integrating poles, pressure relief valves (PRV), PTC resistors, and fuses. Our solutions simplify complex, multi-feature manufacturing:

Integrated Mold Design: One-stop stamping dies for cover plate bases, safety component mounting holes, and pole assembly features—reducing production steps by 25%.
Material & Process Compatibility: Stamping high-strength aluminum alloys (6061, 5052) and stainless steel (304) with precision laser welding prep (edge tolerance ±0.02mm).
Safety-Focused Engineering: Ensures PRV seat flatness and fuse mounting accuracy, directly supporting battery thermal runaway protection.

4. Other Critical Battery Hardware Solutions

Beyond core components, we deliver stamping and mold solutions for:

Busbars: Precision-stamped copper/aluminum/copper-aluminum composite busbars with plated surfaces (tin/nickel) for low resistance.
Cell Case Components: Stamping dies for aluminum alloy prismatic cell cases and stainless steel cylindrical cell caps.
Insulation Spacer Trimming: Precision cutting dies for PP/PE/ceramic fiber spacers, ensuring dimensional accuracy for short-circuit prevention.
