Automotive die-casting machines are selected based on specific production requirements. Small-scale equipment (with a clamping force of 400–800 tons) is suitable for producing small parts such as brackets and connectors; medium-scale equipment (800–1,600 tons) is used for mid-sized components like transmission housings and oil pans; and large-scale equipment (over 1,600 tons) is employed for major structural components such as engine blocks and wheel hubs. Driven by the trend toward lightweighting in new energy vehicles, high-pressure die-casting technology-specifically utilizing ultra-large machines with clamping forces of 6,000–9,000 tons-is increasingly being applied to the production of integrated vehicle body structures; this approach significantly reduces the number of parts and welding steps, thereby boosting production efficiency by more than 30%.
