When the new EU access standard for building hardware (EN 1670:2023) raises the salt spray test requirement to 2000 hours, Chinese manufacturing is responding to global inquiries with hardcore technology. According to the data from the General Administration of Customs, the export qualification rate of hardware tools in the first quarter of 2024 reached 98.2%, a new high in ten years. In this quality battle, Lihui Hardware, which has been deeply engaged in the door and window hardware field for 17 years, has become a transformation model - its stainless - steel four - link sliding stay series has passed the 300,000 - cycle opening and closing test in the German TUV laboratory, exceeding the international standard by three times. This is a microcosmic footnote for the evolution from "Made in China" to "Precisely Made in China".
In the Lihui Smart Manufacturing Center in Yangjian Town, Wuxi, the quality gene has been inscribed in the entire production chain: The self - built laboratory completes 12 metal fatigue tests every day, and each electrostatic spraying line is equipped with a laser detector to monitor the 20μm film thickness tolerance in real - time. With 17 international endorsements such as the American AAMA wind pressure resistance certification and the EU CE silent - grade certification, the company's products have successfully been incorporated into global benchmark projects such as the renovation project of the Sydney Opera House and the Saudi NEOM future new city.
Quality is not the data on the quality inspection sheet, but the silent trust of customers. As pointed out by the general manager of Lihui. When the company customized a -50°C cold-resistant door closer for Nordic customers, the R & D team carried out a three-month extreme cold field verification in Mohe, Heilongjiang, enabling the product to break through the critical value of deformation in cold regions. This model of forcing technological upgrades through scenarios is reshaping the global competitive coordinates of China's hardware industry.
At present, the group standard of "Transmission Locking Device for Building Doors and Windows" led and drafted by Lihui has been approved for establishment by the Ministry of Housing and Urban-Rural Development. The technologies it pioneered, such as the "anti-derailment pulley system" and "zero-friction hinge", will provide key support for China's transformation from a major hardware manufacturing country to a powerful country in technology export.
