Specialized Stamping Sheet Metal Products for New Energy Vehicles: Powering the New Era of Green Mobility
Driven by the global "dual carbon" goals, the new energy vehicle (NEV) industry is experiencing explosive growth. From Tesla's global capacity expansion to European countries accelerating the phase-out of fuel - powered vehicles, NEVs have become an international focus. Our stamping sheet metal products, with innovative technologies and superior performance, are deeply integrated into the entire NEV manufacturing industry chain, providing core support for green mobility.
I. Lightweight Design: Extending Range and Reducing Energy Consumption
To meet the core demand of NEVs for driving range, we use aviation - grade aluminum alloys and high - strength thermoformed steel as the main materials. Through optimized material ratios and structural designs, the weight of key body components is reduced by more than 30%. For example, the battery pack frame is formed by stamping high - strength aluminum alloy. While ensuring structural strength, it effectively reduces the overall vehicle weight, helping NEVs achieve longer driving ranges. Meanwhile, the lightweight design significantly reduces energy consumption during vehicle operation, eases the burden on the battery, and extends the battery's service life, offering users a more efficient and economical travel experience.
II. Precision Machining Processes: Ensuring Safety and Stable Performance
1. Stamping Forming
We employ high - precision servo stamping equipment in conjunction with digital mold design to achieve micron - level machining accuracy. Take the automotive crash beam as an example. Through precise stamping forming, it can collapse in an orderly manner during a collision, effectively absorbing impact energy and providing reliable safety protection for drivers and passengers. Additionally, the precise stamping process ensures dimensional consistency of components, improves overall vehicle assembly accuracy, and reduces performance losses caused by assembly errors.
2. Laser Welding
Advanced laser welding technology is used to achieve seamless welding of stamping sheet metal parts. In the manufacturing of battery pack casings, the welds formed by laser welding are uniform and dense, with excellent sealing and waterproof performance. This effectively prevents risks such as battery moisture ingress and short circuits. Moreover, the high - strength connections created by laser welding enhance the overall rigidity of the battery pack, enabling it to stably withstand the vibrations and impacts from various complex road conditions during vehicle operation.
3. Bending Forming
In response to the complex body structures of NEVs, our bending process can achieve high - precision multi - angle bending. When manufacturing components such as doors and roofs, by precisely controlling the bending angle and curvature, we ensure that the components perfectly match the overall body shape. This not only enhances the vehicle's aesthetic appeal but also optimizes aerodynamic performance, reduces the drag coefficient, and further improves the vehicle's driving range and driving stability.
III. Surface Treatment: Aesthetic, Durable, Environmentally Friendly and Energy - Efficient
1. Environmentally Friendly Coating
We adopt water - based paint coating processes. Compared with traditional solvent - based paints, the emission of volatile organic compounds (VOCs) is reduced by more than 80%, meeting international environmental protection standards. The coating has excellent wear resistance, corrosion resistance, and weather resistance. Even under extreme climatic conditions, the vehicle's appearance can remain as good as new. Meanwhile, a wide range of color options and personalized coating solutions meet the diverse aesthetic requirements of different customers for vehicle appearances.
2. Anti - Scratch and Wear - Resistant Treatment
For easily worn parts of the vehicle, such as the lower part of the doors and wheel arches, special anti - scratch and wear - resistant coating treatments are applied. This coating has high hardness and good self - healing properties, effectively resisting scratches and collisions during daily use, reducing vehicle maintenance costs, and extending the vehicle's service life. In addition, the anti - scratch and wear - resistant treatment can also enhance the vehicle's residual value, bringing higher value returns to users.
In the fast - developing wave of the NEV industry, our stamping sheet metal products, with innovative technologies, superior quality, and environmental protection concepts, provide solid guarantees for the safe, efficient, and sustainable development of NEVs. We will continue to innovate, move forward together with the global NEV industry, and promote green mobility to new heights.
