Core Viewpoint - The technological strength and market competitiveness of Haimeixing Laser have once again been recognized in the international market through the successful shipment of its self-developed 480V high-voltage electrode and negative electrode winding drying line to the U.S. market [1][3]. Group 1: Equipment Performance and Achievements - Haimeixing has successfully overcome the challenge of vacuum discharge in a 480V high-voltage application environment, achieving energy savings of 30%-70% and efficiency improvements of ≥200 PPM [2][5]. - The equipment has passed the stringent UL certification in the U.S., indicating that it meets the rigorous testing and recognition standards in design, manufacturing, and performance [5]. Group 2: Market Challenges and Solutions - The U.S. market presents a significant challenge for battery manufacturing equipment due to its 480V voltage standard, which differs from the 380V design commonly used in other regions [4]. - Vacuum discharge poses a risk in high-voltage environments, where gas ionization can lead to sudden current increases, potentially causing damage or safety hazards [4]. Group 3: Technological Innovations - The vacuum drying equipment integrates drying and cooling functions, utilizing a dry vacuum pump that produces clean vacuum without liquid media, ensuring no contamination [5][6]. - The design features independent chambers with a low vacuum leak rate of ≤10 Pa.L/s and a maximum vacuum degree of <10 Pa under no load, ensuring high performance and safety [6]. - Haimeixing has optimized the heating technology to achieve uniform temperature distribution, with an empty load temperature uniformity of ±3℃ and a maximum deviation of ≤+3.0℃ during the constant temperature phase [7].
