Power lithium battery precision structural parts belong to a high-tech industry with multi-technology crossover and high process quality requirements, while the new energy vehicle industry is still in its infancy, and the technical route is still uncertain. time.
Regardless of the technical route, the precision structural parts of the power lithium battery will still be a key component of the power lithium battery. The precision mold design and manufacturing, precision stamping, friction welding, precision drawing and injection molding involved in the production of the precision structural parts of the power lithium battery Molding and other technologies have also been developed by leaps and bounds.
In terms of precision mold design and manufacturing, the quality of the mold determines the accuracy and quality of the product, especially the key processing and manufacturing technologies for the core components of the explosion-proof disc and the reversal disc. At the same time, due to the wide variety of specifications, models and types of power lithium battery products, each product needs to manufacture molds separately. Enterprises with strong mold development capabilities may respond to customer needs in a timely manner and rapidly expand their business;
In terms of precision stamping processing technology, the power lithium battery precision structural parts manufacturers use excellent stamping processing technology to improve precision, production efficiency, stability, degree of automation, and reduce energy consumption and material consumption;
In terms of friction welding technology, through the copper-aluminum friction welding process, the electric performance of the pole is still stable in the long-term use environment. This technology is only mastered by a few leading companies in the industry;
In terms of stretching technology, it realizes structural parts with high consistency in one-step stretching; in terms of injection molding processing technology, it meets the needs of power lithium batteries for the strength and resistance of plastic parts.
With the increasing requirements of downstream customers on the accuracy of motor cores and the intensification of market competition, the large-scale production of large-scale enterprises in the industry is also moving towards high-precision, high-efficiency, high-stability, and low-consumption materials. Development, thereby promoting the level of mold, automatic or semi-automatic lamination tooling is greatly improved.
The development trend of power lithium battery to improve energy density, reduce cost and light weight promotes the continuous improvement of the power lithium battery precision structural parts industry’s requirements for product strength, safety, production efficiency, etc., and the lithium battery industry has accumulated foundations in existing products and technologies On the way, constantly explore cutting-edge high-precision cutting-edge technology and realize the industrialization development of technology. Therefore, higher standards are also put forward for the continuous technological innovation, product replacement speed, and research and development capabilities of leading companies in the power lithium battery precision structural parts industry.
In terms of safety, as the volume of power lithium batteries increases, the energy density increases, and the use environment becomes more complicated, the hidden danger of explosion caused by damage to sealed batteries is also increasing. The explosion-proof design of power lithium batteries is related to product quality and The most important factor for safety. It is one of the research frontiers in the industry to research and develop the process of precision structural parts of power lithium batteries, reasonably set safety valves, and manage battery pressure relief and power outages before pressure relief through circuit-break protection and pressure relief protection.
In terms of welding process, the material application, laser welding process, friction welding process, and precision of welding points in the power lithium battery precision structural parts industry are related to the battery’s electrical conductivity, service life and even safety.
As downstream customers have higher and higher requirements for precision structural parts of power lithium batteries and market competition has intensified, in order to ensure faster response speed and higher production efficiency, enterprises in the industry will automate precision structural parts according to their own actual conditions. Equipment research and development, rapid adjustment of flexible production lines, and continuous improvement of the aforementioned high-efficiency production technologies, as well as guarantees through precision production equipment and high-quality production environment, so as to ensure product consistency and stability, reduce manufacturing costs, improve production efficiency, and enhance production. Competitiveness.
