据江苏鑫海高导新材料有限公司官微消息：近日，江苏鑫海高导新材料有限公司全资子公司——安徽鑫海高导新材料有限公司（以下简称 “鑫海高导”）四期 "新能源汽车及机器人电子信号通讯用超细铜导体产业化项目"传来重磅进展，依托对客户需求的深度洞察与自身技术的持续精进，公司携手全球线缆行业顶尖设备商德国尼霍夫（Maschinenfabrik Niehoff GmbH & Co. KG）以及知名模具商伊斯特伟斯·中国（ESTEVES），历经百次工艺迭代，成功研发出全球首例采用连铸连轧低氧铜杆母线生产16 x 0.042mm超细多股微伸铜导体，该生产工艺在16头德国尼霍夫MMH 50微拉多头生产线上完成并经德国尼霍夫公司正式确认。此外，公司已经实现39万米/盘、连续 6 小时不间断稳定试产！此举突破了MMH 50型设备0.05毫米的设计最小出线直径。根据德国尼霍夫过往的经验，出线直径至0.05 mm线规的连续生产通常采用上引法无氧铜杆。采用连铸连轧低氧杆连续生产16 x 0.042 mm这一成果填补了德国尼霍夫多头设备在连铸连轧低氧铜杆应用多头拉丝连续退火工艺生产超细导体的技术空白。彰显了鑫海高导“以客户需求为核心，持续突破自我、精进技术能力” 的发展理念，为后续规模化服务客户筑牢核心技术储备。

A major breakthrough was recently achieved in the Phase IV of the "Industrialization Project of Ultra-Fine Copper Conductors for New Energy Vehicles and Robot Electronic Signal Communication" of Anhui Xinhai High Performance Copper New Materials Co., Ltd. — a wholly-owned subsidiary of Jiangsu Xinhai High Performance Copper New Materials Co., Ltd. (hereinafter referred to as "Xinhai High Performance Copper "). Relying on in-depth insights into customer needs and continuous development of its own technology, the company, in collaboration with the world's top equipment manufacturer in the wire & cable industry - Maschinenfabrik Niehoff GmbH & Co. KG (Germany) and the well-known drawing die supplier Esteves China, underwent hundreds of process iterations. It successfully developed the world's first 16 x 0.042mm ultra-fine multi-wire drawn copper conductor from continuous casting and rolling of low oxygen copper rods. This process was completed on a NIEHOFF MMH 50 multi-wire drawing and annealing line, and it was officially confirmed by NIEHOFF. Furthermore, the company achieved stable trial production of 390,000 meters per spool with 6 consecutive hours of uninterrupted operation. This achievement breaks through the minimum designed finishing diameter of 0.05 mm.Based on NIEHOFF’s previous experience, a finishing diameter of 0.05 mm generally requires the use of Upcast Oxygen-Free Copper (OFC) rods for continuous production. However, using continuous casting and rolling copper rods to produce 16 x 0.042 mm fills the technical gap in the application of NIEHOFF machines using continuous casting and rolling low oxygen copper-based ultra-fine conductors through a multi-wire drawing and continuous annealing process. This achievement demonstrates Xinhai's development philosophy of "centering on customer needs, continuously breaking through, and refining technical capabilities." It lays a solid foundation for core technological reserves to serve customers on a large scale in the future.
