Congratulations on the successful acquisition of a patent certificate (Patent No.: ZL202411317060.6) for our company's independently developed "Battery Shell Production Line and Battery Forming Process" technology by the National Intellectual Property Administration! This honor marks a new phase in PHP's technological innovation in the field of composite material hydraulic presses, providing core support for the advancement of new energy battery manufacturing processes.
This patent focuses on a systematic solution for the battery case forming process in HP-RTM servo composite hydraulic presses. By optimizing material impregnation, curing molding, and process stability, it addresses pain points such as low efficiency, high energy consumption, and insufficient product consistency in traditional processes. The core of the patent includes an intelligent upgrade of high-pressure resin transfer molding (HP-RTM) technology, combined with heated vacuum degassing, precise injection control, and energy-saving piping design. This can significantly enhance the mechanical properties and production yield of battery cases, providing lightweight, highly reliable battery enclosures for use in new energy vehicles and energy storage applications.
Other processes for battery shell molding:
SMC molding process
SMC (Sheet Molding Compound) molding is an efficient and high-precision composite material processing technology. In the molding process of battery shell, its characteristics are mainly reflected in the following aspects:
1. Rapid molding cycle: SMC molding cycle is short, the molding time of a single product is usually 3-5 minutes, suitable for mass production.
2. Automatic integration: the molding process can achieve a fully automatic production line, which is significantly more efficient than traditional hand lay-up or injection molding processes.
3. Multi-mode cavity parallel production: multiple cavities can be placed in the same template to further improve production capacity.
4. Heating system integration: PHP's SMC press can effectively integrate various heating methods, such as mold temperature oil heating, electric heating control system, steam heating system, etc.
PCM moulding process
PCM (Prepreg Compression Molding, prepreg compression molding) molding process is an efficient composite material manufacturing method combining the characteristics of prepreg and molding technology, especially suitable for new energy vehicle battery shell and other scenarios with high requirements on lightweight, strength and precision.
PCM molding process can form complex geometric structures containing reinforcing ribs, inserts and deep cavities in one time, reducing the number of parts and assembly steps. For example, the flange surface of the battery shell is designed with layered laying to achieve overall structural optimization and avoid strength loss of the separate design.
In addition, the molding cycle is short (3-5 minutes per piece), and it supports fully automatic production line, with an annual capacity of 50,000-70,000 pieces. The 1000ton PCM molding press produced by PHP has served BYD and other car companies.
In the future, PHP will continue to delve into the field of composite material hydraulic forming, leveraging more groundbreaking patent technologies to support the global energy structure transformation, and fulfilling its mission to "make advanced manufacturing more efficient and clean energy more accessible." The awarding of this patent certificate is not only an authoritative endorsement of our technical capabilities but also a significant milestone on the path to becoming a "specialized, refined, unique, and innovative" company. We look forward to working hand in hand with industry partners to jointly advance the innovation and breakthroughs in battery manufacturing processes.
