Technological upgrades of current automotive spring equipment are mainly driven by the in-depth transformation of the automotive industry toward electrification, lightweighting and intelligence, as well as the industry’s higher requirements for production efficiency, product quality and environmental protection. The superposition of multiple driving forces promotes continuous breakthroughs in equipment technology.
With the rising penetration rate of new energy vehicles, the increased weight of batteries has driven a rapid surge in demand for suspension springs with larger diameters and higher strength. Traditional spring production equipment can hardly meet the requirements of durability and quality uniformity under high-load conditions. Meanwhile, the pursuit of longer cruising range in new energy vehicles has spurred a sharp demand for spring lightweighting. The application of new materials such as magnesium-aluminum alloys and composite materials has forced technological upgrades of spring equipment to adapt to the processing requirements of new materials. In addition, the popularization of 800V high-voltage platforms has raised higher requirements for springs in terms of signal compatibility and corrosion resistance, further driving spring equipment toward precision and customization.
