一、压铸机主机

一体化压铸绝对核心设备，占整线投资35-45%，吨位6000-16000T决定零件尺寸与成本; 6000T是量产甜点位，国产三强(力劲+海天+伊之密)占全球6000T装机70%（在产品零件上拓普独家供Model Y后底板/文灿产问界M9/鸿图供小鹏蔚来）Integrated die-casting absolute core equipment, accounting for 35-45% of the entire line investment, with a tonnage of 6000-16000T determining part size and cost;  6000T is a mass-produced dessert spot, The top three domestic brands (Lijin, Haitian, and Yizhimi) account for 70% of the global 6000T installed capacity (exclusive supply of Model Y rear bottom plate by Topu in product parts/M9 from Wencan Production and Consulting Industry/Hongtu for Xiaopeng NIO)

二、熔炼与保温设备

铝液集中熔化→保温→除气精炼→转运，是压铸产线最耗电、人员最密集的工段；主流设备还是德国占有优势，国产替代进行中>50%。The centralized melting of aluminum liquid → insulation → degassing and refining → transportation is the most power consuming and personnel intensive section of the die-casting production line; Mainstream equipment still has an advantage in Germany, with domestic substitution in progress>50%.

三、去毛刺、切边与检测设备

CNC后处理国产化率~75%(海天精工/力劲替代GROB/DMG)/去毛刺+质检国产化率~60%(新松/埃斯顿/海康/凌云光)仍在追赶；The localization rate of CNC post-processing is around 75% (Haitian Precision/Lijin replaces GROB/DMG), while the localization rate of deburring and quality inspection is around 60% (Xinsong/Estun/Hikvision/Lingyun Guang), which is still catching up;

四、热处理与时效设备

国产化率 ~65%；免热处理铝合金可省掉热处理段(占2-3%投资)/进一步降本并缩短交付周期；Localization rate~65%; Non heat treated aluminum alloy can save the heat treatment section (accounting for 2-3% of the investment)/further reduce costs and shorten delivery cycles;
