As the global transition to renewable energy accelerates, Ningbo Puppet Steel Co., Ltd. has expanded its specialized metallurgical expertise to meet the stringent demands of high-performance nickel strips. Nickel strips are the lifeblood of battery pack interconnects, requiring precise resistance control, high-purity composition, and stringent CE compliance to serve European and international markets effectively.
Our engineering team focuses on the microscopic properties of nickel strips. By optimizing grain boundary structures and surface oxidation levels, we ensure low resistance, which minimizes heat generation during high-discharge cycles in EV and energy storage systems (ESS). Our tech roadmap includes the adoption of laser-welding optimized surface finishing, providing a superior bond in automated assembly lines.
Located in the heart of Ningbo’s industrial hub, Puppet Steel leverages a vertically integrated supply chain. We don’t just supply; we engineer. Our proximity to major shipping ports allows for rapid deployment of raw materials and finished goods. During global supply chain volatility, our facility maintains deep inventory reserves of cathode and anode raw materials, ensuring that our partners avoid production downtime.
Whether for consumer electronics, power tools, or industrial scale battery modules, our nickel strips meet international electrochemical standards. We provide material certifications that are crucial for CE marking, ensuring our clients’ final products pass regulatory scrutiny in the EEA (European Economic Area). Our products undergo rigorous ASTM and DIN testing to match the specific thermal conductivity required by your pack design.
Ningbo Puppet Steel Co., Ltd. remains a professional Steel Sheet Manufacturer and global supplier. We offer cold rolled, hot rolled, and galvanized steel sheets, serving sectors like construction, infrastructure, and automotive. Our specialized manufacturing facilities operate with precision quality inspection systems to ensure dimensional accuracy and long-term durability. We are committed to fostering long-term partnerships with fabricators and wholesalers across North America, Europe, and Southeast Asia.
A: For components used in consumer energy products (like battery packs), CE certification ensures that materials meet health, safety, and environmental protection standards in the EEA. Utilizing certified suppliers mitigates compliance risks for the final manufacturer.
A: Through automated, digital-twin monitored production lines. We utilize precision spectroscopy to ensure alloy purity, which is critical for consistent electrical resistance in nickel strips.
A: Yes, we offer full OEM/ODM services, from custom width slitting, specific temper annealing, to specialized surface coatings for corrosion resistance.
