Guangdong Hongtu Technology Co., Ltd. and Yizumi Company both have 9,000-ton ultra-large die-casting machines. These die-casting machines are mainly used for the production of integrated die-casting parts for new energy vehicles to meet the needs of lightweight vehicles, reduce body weight, reduce energy consumption and improve cruising range. The application of these large die-casting machines demonstrates China's progress and development in the field of die-casting technology, especially its attention and investment in the manufacturing of new energy vehicle structural parts. For example, Yizumi uses a 9,000-ton ultra-large die-casting machine to produce one-piece die-casting parts that are mainly used in new energy vehicles to reduce vehicle body weight, reduce energy consumption, increase cruising range, and meet vehicle lightweight requirements.
