HNC assists in the intelligent manufacturing of five-axis molds for new energy vehicles
A New Era: New Energy Vehicles Create New Opportunities for the Industry
In the era of traditional gasoline-powered vehicles, the requirements for machining precision and the reliability of core components—such as engines and transmissions—were extremely stringent. Domestic high-end machine tools struggled to match the stability found in products from countries like Germany, Japan, and Switzerland, resulting in a heavy reliance on imported five-axis CNC machine tools for high-end automotive production lines. Recent market data indicates that German, Japanese, and American brands have dominated the top 25 best-selling sedans in China. The supply chains of these automakers are largely connected to domestic machine tool brands, which makes it challenging for traditional domestic machine tool companies to enter the high-end market.
The rise of new energy vehicles has completely disrupted this pattern. Their core has shifted to batteries, motors, and electronic controls. This structural change has significantly weakened the West’s technological advantage in traditional engine manufacturing, putting domestic and foreign companies on a much closer starting line. New processing requirements are better suited to the characteristics of domestically produced equipment: battery trays require large gantry milling machines, emphasizing high efficiency and large-scale production; the motor housing structure is relatively simple, reducing processing difficulty and precisely avoiding the traditional weaknesses of domestically produced machine tools.
China has become the world’s largest new energy vehicle market. According to data from the China Association of Automobile Manufacturers, in 2008, my country’s new energy vehicle sales were only 1,500 units, accounting for approximately 0.0016% of the global market. By 2023, sales had soared to 9.495 million units, accounting for 31.6% of the global market and exceeding 60% of the global market share. By 2024, sales were projected to exceed 10 million units, with the domestic market accounting for 40.9% and the global market share exceeding 70%. Domestic OEMs such as BYD have been actively promoting the localization of their supply chains, providing valuable opportunities for trial and error and iteration for domestically produced equipment. Taking a best-selling BYD model as an example, its starting price has dropped to a highly competitive range, yet it still maintains considerable profit margin per vehicle. One of the core reasons is the use of domestically produced machine tools and CNC systems, fully highlighting the high cost-performance advantage of domestically produced equipment in terms of both quality and cost.
