Low-end automotive stamping dies have traditionally relied on manual techniques performed by skilled fitters. However, as modern CNC machining technology continues to evolve, high-end automotive stamping die manufacturers must now invest in advanced equipment such as large-scale gantry five-face machining centers, large-scale gantry five-axis machining centers, and large-scale gantry three-coordinate measuring systems, along with sophisticated online measurement technologies. This shift is essential for developing high-end mold manufacturing capabilities, particularly for complex surface parts of vehicles, including engine covers, front and rear panels, radiator grilles, door panels, side panels, roofs, and chassis components. These parts are not only larger in size but also require extremely high-quality standards due to their structural complexity.
To meet these demands, manufacturers need large-stroke, high-precision machining equipment and advanced testing systems. The machine tool strokes typically require at least 4 meters on the X-axis, 3 meters on the Y-axis, and 1 meter on the Z-axis. For large-scale automotive cover molds, it is crucial to use large gantry CNC machines and coordinate measuring equipment. Only through this combination can the quality, production schedule, and cost of the molds be effectively controlled and accepted by the market.
Currently, over 70% of the large-scale CNC equipment needed for manufacturing automotive panel molds, especially five-axis gantry systems, are still imported. To innovate and develop high-quality, large-scale high-end molds, it is vital to enhance the development capabilities of both machining and testing equipment. This includes focusing on the research and development of ultra-heavy-duty gantry machining centers with dynamic beams ranging from 4 to 5 meters, large-scale three-coordinate and five-axis linkage CNC gantry machines, and key core components such as high-speed precision electric spindles, robotic tool magazines, CNC rotary tables, high-speed safety devices, power tool holders, and dual-rotation milling heads. At the same time, continuous investment in the development of advanced CNC machine tools remains a priority for long-term growth and competitiveness in the industry.
