压铸市场-2026-2031年预测Die Casting Market - Forecast from 2026 to 2031 |
||||||
预计压铸市场将从 2025 年的 912 亿美元成长到 2031 年的 1,268.64 亿美元,复合年增长率为 5.66%。
压铸是一种高压金属成形工艺,将主要由铝、锌、镁和少量铜组成的熔融合金在600至1200巴的压力下注入精密钢模中。此製程可生产近净成形零件,具有优异的尺寸重复性(±0.02毫米)、薄壁能力(低至0.8毫米)以及无需二次加工的表面光洁度。铝高压铸的循环时间可达15至90秒,模具寿命超过10万次,因此是高产量、复杂形状零件的理想选择,特别适用于对结构性能和轻量化要求极高的应用。
铝是高压铸 (HPDC) 的主要材料,约占全球市场份额的 80%。其优异的强度重量比、导热性、耐腐蚀性和可回收性完美契合轻量化车辆的需求以及电动动力传动系统总成日益普及的趋势。结构件(例如电池外壳、减震塔、前轴支架和后副车架)通常采用超大型铸造製程生产,面积超过一平方公尺,重量超过 80 公斤,使用夹紧力达 6,000 至 12,000 吨的机器。一个超大型铸造件可取代 70 至 100 个冲压或焊接件,与钢结构相比,可组装复杂性降低 30% 至 40%,并将车辆重量减轻 10% 至 15%。
汽车产业仍是压铸件的主要终端市场,占全球压铸件产量的55-60%。电气化正在加速铝材使用量的成长。一辆典型的纯电动车(BEV)由于其温度控管组件(逆变器外壳、冷却板)和大型结构节点,需要使用150-250公斤的高压铸铝,而同等配置的内燃机汽车(ICE)仅需80-120公斤。镁合金虽然仍处于小众市场,但在需要进一步减轻重量的领域,例如仪表板、座椅框架和电池托盘盖,其应用正在增加。
消费性电子产品和5G基础设施是第二大成长领域。智慧型手机、笔记型电脑和通讯设备所需的小型薄壁锌铝合金机壳,壁厚需小于1毫米,并整合电磁屏蔽和散热鳍片-这些结构特别适合压铸製程。更快的製造週期和新开发的低铁铝合金降低了外观零件的废品率,使得以前需要从坯料加工的结构件和温度控管件能够透过压铸製程製造。
技术进步主要集中在四个关键领域:
亚太地区在消费和机械设备生产方面持续保持主导,光是中国就占全球高压压铸产能的55%以上。在汽车和电子原始设备製造商(OEM)在地化策略的推动下,印度和越南已成为新的生产中心。
永续性正迅速从边缘问题转变为核心问题:流道系统和消费后废料的闭合迴路回收利用现在已成为常态,材料回收率超过 95%,而低碳原生铝和可再生能源铸造厂正成为欧洲和北美 OEM 供应链的一项要求。
总之,压铸产业正处于一个转折点,电气化、巨型铸造规模化以及热整合和结构整合正在推动近20年来最大的资本支出週期。在零件集中度和车辆重量直接影响续航里程、性能和法规遵循的环境下,能够提供具有真空辅助、无气孔微观结构和全程可追溯性的大型可靠结构铸件的铸造厂将获得显着的市场份额。

Die Casting Market is projected to expand at a 5.66% CAGR, attaining USD 126.864 billion in 2031 from USD 91.200 billion in 2025.
Die casting is a high-pressure metal forming process that injects molten alloy-predominantly aluminum, zinc, magnesium, and to a lesser extent copper-into precision steel dies at 600-1,200 bar, achieving near-net-shape components with exceptional dimensional repeatability (+-0.02 mm), thin-wall capability (down to 0.8 mm), and surface finishes often eliminating secondary machining. Cycle times of 15-90 seconds and die life exceeding 100,000 shots in aluminum HPDC make the process the preferred route for high-volume, complex geometry parts where structural performance and weight reduction are paramount.
Aluminum dominates with approximately 80 % global volume share in high-pressure die casting (HPDC). Its specific strength, thermal conductivity, corrosion resistance, and recyclability align perfectly with automotive lightweighting mandates and the parallel surge in electrified powertrains. Structural castings-battery housings, shock towers, front-end carriers, and rear subframes-are now routinely specified in gigacasting configurations exceeding 1 m2 and 80 kg single-piece weight, enabled by 6,000-12,000 tonne clamp-force machines. A single gigacasting can replace 70-100 stamped/welded parts, reducing assembly complexity by 30-40 % and vehicle mass by 10-15 % versus steel architectures.
Automotive remains the anchor end-market, accounting for 55-60 % of global die-cast tonnage. Electrification is accelerating aluminum intensity: a typical BEV contains 150-250 kg of aluminum HPDC versus 80-120 kg in comparable ICE vehicles, driven by thermal management components (inverter housings, cooling plates) and large structural nodes. Magnesium, while still niche, is gaining in instrument panels, seat frames, and battery tray covers where further mass reduction is required.
Consumer electronics and 5G infrastructure represent the second-fastest growth vector. Miniaturized, thin-wall zinc and aluminum housings for smartphones, laptops, and telecom equipment demand sub-1 mm walls with integrated EMI shielding and heat-dissipation fins-geometries uniquely suited to die casting. Falling cycle times and new low-iron aluminum alloys have lowered defect rates in cosmetic applications, enabling structural/thermal parts previously machined from billet.
Technological advancement is focused on four key areas:
Asia-Pacific continues to dominate both consumption and machine/equipment production, with China alone accounting for >55 % of global HPDC capacity. India and Vietnam are emerging as secondary hubs driven by automotive and electronics OEM localization strategies.
Sustainability is rapidly moving from peripheral to core consideration. Closed-loop recycling of runner systems and post-consumer scrap now routinely exceeds 95 % material yield, while low-carbon primary aluminum and renewable-powered foundries are becoming table-stakes for European and North American OEM supply chains.
In conclusion, the die-casting industry sits at an inflection point where electrification, gigacasting scale-up, and thermal/structural integration are driving the highest capital investment cycle in two decades. Foundries capable of delivering large-format, high-integrity structural castings with vacuum-assisted pore-free microstructures and full traceability will capture disproportionate share in an environment where part consolidation and vehicle weight directly impact range, performance, and regulatory compliance.
