At 5:30 pm on April 2nd, in the copper foil production workshop of ZLHZ Copper's second-stage project of high-precision copper plate and foil project, all technicians and workers on site were excited to witness the successful production of 8 micron high-end alloy foil A moment of joy.
After two months of equipment maintenance, commissioning, and commissioning, the copper foil workshop of ZLHZ Copper has successfully rolled 8 micron high-end alloy foil through several procedures through 25 micrometers of incoming materials, which successfully refreshed the company at the end of January. A record for the production of 9 micron copper foil. This 8 micron product is an alloy foil with a length of about 2300 meters and a width of 600 millimeters. Its thickness, flatness and other indicators have reached domestic leading levels. The rolling difficulty is more difficult than that of 9 micron copper foil. To be strict, the technical difficulty is higher.
High-precision rolled copper foil is the main raw material for graphene substrates, flexible printed circuit boards, and flexible connections. It is widely used in electronic appliances, communications, integrated circuits, aerospace and other fields. It is heavily dependent on imports in China, and the domestic substitution situation is grim.
In recent years, ZLHZ Copper has been positioning itself on "replacement of imports and export-oriented", and is determined to be driven by innovation and industrial upgrading. In September 2017, the company invested more than 1 billion yuan to build the second phase of the Huazhong Copper Industry and high-precision copper plate and foil project. In January 2019, after 15 months of hard work, the project was completed and put into production. The newly added capacity is 60,000 tons / year, of which 3,000 tons of high value-added high-precision rolled copper foil enables the company to reach a total production capacity of 90,000 tons / year, with an annual output value of 5 billion yuan, ranking it as domestic rolled copper , Tape, foil production scale first.
"The record is used to break! Only with the courage to innovate and continue to break through ourselves can we be invincible. We are confident and capable of moving towards the goal of developing the world-leading 6-7 micron high-end copper foil, Production of high-quality copper foil to meet the needs of domestic and foreign markets.
