Hirakawa指出，T-glass的生产工艺极为复杂，竞争对手短期内难以复制日东纺的技术优势。尽管该公司计划在2028年前将产能提升至2025年水平的三倍，并于2026年下半年启动稳步扩产，但对当前急需原料的客户而言，这一节奏仍显滞后。市场紧张局势已迫使消费电子厂商改变传统策略。知情人士透露，苹果等公司近期向日本增派管理人员，直接与日东纺谈判以锁定供应。通常，这类上游材料供应商距离终端产品尚有数道工序，厂商极少介入，但此次供应链压力已打破常规。日东纺在书面回应中表示：“电子与半导体制造商终于认可玻璃纤维布作为关键材料，这是积极的发展。”上一财年，该公司营业利润创下约1.04亿美元的历史新高。不过，公司也对需求可持续性持谨慎态度：“人工智能需求正在流星般飞速增长，但我们预计这种增长率不会持续下去。”业内人士称，英伟达等资金雄厚的AI企业往往能优先获得零部件，而消费电子产品因优先级较低，可能成为短缺重灾区。日东纺已警告，新增产能仍难弥补当前供需缺口，并计划年内提价。花旗分析师预测，涨幅或超过25%，最终成本很可能传导至智能手机与笔记本电脑的零售价格。值得注意的是，T-glass并非唯一被忽视却至关重要的上游材料。例如，以味精闻名的日本企业味之素，利用其化学技术开发出用于芯片底层的专用薄膜；而英伟达价值百万美元的服务器机架，竟依赖一家中国台湾家具配件商提供的抽屉滑轨。这凸显了全球高科技产业对传统制造业隐形冠军的高度依赖。当前，日本企业在半导体上游材料领域占据主导，但其审慎的扩产文化可能拖慢应对爆发性需求的步伐。在AI算力竞赛白热化之际，一片“玻璃布”的短缺，正折射出全球供应链的脆弱性与重构压力。欢迎点击查看原文，一键直达您的科技区角
