Copper’s Critical Role in New Energy

As the new energy industry surges, copper’s role in powering cutting-edge technologies has never been more critical. JinChuan Group Co., Ltd. is rising to the challenge, aligning its expertise with the needs of new energy vehicles (NEVs), information technology, and aerospace. At the forefront of this effort is JinChuan Niedu Industrial Co., Ltd., where golden-red copper wires, as thick as a finger, are transformed into innovative irregular-shape copper strips—specialized products driving the future of the semiconductor industry.

Unique Design Enhances Applications

Unlike traditional flat copper strips, these irregular-shape strips feature a distinctive T-stand protrusion, a design that enhances their utility in advanced applications. “This unique shape is why we call it ‘irregular,’” explains Liu Jianbin, deputy manager of the Semiconductor Packaging Department at JinChuan Niedu Industrial. Now widely adopted in 5G communication equipment, NEV components, and consumer electronics, these strips are proving indispensable in high-tech sectors demanding precision and durability.

Breaking Through Technological Barriers

Before 2018, the production technology for irregular-shape copper strips was a closely guarded secret, dominated by countries like Japan and France, leaving China reliant on imports. Facing this technological blockade, JinChuan Group took action. Partnering with domestic research institutes, the company spent nearly two years innovating on its existing production line. The result was a game-changing breakthrough: the development of core forging and stamping equipment. This advancement reduced the traditional 12-step rolling process to a single, efficient pass, dramatically improving production speed, product quality, and dimensional accuracy.

Leading with Dual-Process Mastery

Liu Jianbin proudly notes that JinChuan is now the only company in China mastering both rolling and forging processes for irregular-shape copper strips. Compared to standard rolled strips, JinChuan’s products offer superior performance, meeting the exacting standards of modern semiconductor applications. With an annual production capacity of 7,000 tons, the company has emerged as a national leader, breaking foreign monopolies and bolstering China’s self-sufficiency in this critical technology.

Pioneering a Connected Future

This innovation aligns with JinChuan Group’s broader mission—echoed in President Xi Jinping’s call for innovation-driven development—to build a world-class brand through technological excellence. By delivering high-precision, cutting-edge copper solutions, JinChuan is not only supporting the semiconductor industry’s growth but also strengthening its own reputation as a pioneer in new materials. As demand for specialized copper products rises, JinChuan’s irregular-shape copper strips are paving the way for a smarter, more connected future.
