Forging Process Upgrades + Lightweight Materials Drive Cost-Efficiency Breakthroughs in the Component Industry

As new energy vehicles (NEVs) continue to demand "weight reduction and energy consumption cuts," the automotive and construction machinery component sectors are accelerating the integration of forging processes and advanced materials. A key industry trend now is linking large-scale press equipment (400T-1600T class) with CNC production lines, paired with new processes like semi-solid injection molding, to overcome traditional bottlenecks in lightweight materials (e.g., magnesium alloys). This has not only increased the maximum single-part weight from 5kg to 17kg but also reduced porosity from over 5% to below 1.5%, while boosting material utilization to 85%.

Take automotive structural parts as an example: A 20-inch magnesium alloy wheel (high-strength and corrosion-resistant) is 35% lighter than its aluminum alloy counterpart. E-drive housings manufactured via thixotropic injection molding achieve integrated production, cutting 8 processing steps while increasing thermal conductivity by 15%—directly improving NEV range by 2%-8%. Industry data shows such "process + material" upgrade solutions can help enterprises reduce production costs by over 20%, and they have now been scaled in both OE supply and aftermarket segments.
