Revolutionizing the Knife and Scissors Industry in Yangjiang, Guangdong
Yangjiang, Guangdong, stands as China’s premier hub for the hardware knife and scissors industry, boasting over 70% of the nation’s enterprises and product output, and accounting for more than 85% of national exports. Grinding and polishing are critical steps in the manufacturing of knives and scissors. Due to the complex and variable curves of knife backs and scissor edges, traditional sanding and grinding processes have relied heavily on manual labor. This dependence not only results in severe dust and noise pollution but also exposes workers to high labor intensity and a heightened risk of occupational injuries. The industry’s reliance on skilled workers has led to challenges such as low efficiency, poor precision, inconsistent quality, high energy consumption, and escalating labor costs. These technical bottlenecks have severely hindered the industry’s development and modernization.
In an era where industrialization and electronic information technology are the main drivers of progress, Guangdong Yangjiang Hongfeng Industrial Co., Ltd.—a nationally renowned specialist in small knife production recognized as the “China Small Knife Center” by the China Daily Hardware Technology Center—has taken a pioneering step. In partnership with Yangjiang Yanghang Industrial Co., Ltd., and with enthusiastic support from industry peers, they devoted over two years to successfully develop and manufacture the CNC Knife and Scissors Curve Belt Grinder.
This groundbreaking machine fills a significant technological gap in the domestic market and represents a major breakthrough in common technology within the hardware knife and scissors industry. It employs advanced CNC technology to automate the grinding and polishing of curved surfaces on the sides and external contours of hardware items like knives and scissors. The innovation has been recognized with one invention patent and five utility model patents, with additional patents pending—including three invention patents, two utility model patents, and one international patent.
