Xiamen Pinhe Precision Technology Co., Ltd. is located in Xiamen, Fujian Province. It is a national high-tech enterprise dedicated to the research and production of stone multi line cutting machines, and is also one of the earliest companies in China to start the research and development of stone wire saws. The predecessor of the company was a production and research and development unit for multi line cutting machines for photovoltaic silicon wafers. The core members of the team have over 18 years of experience in multi line cutting machines and production and research and development of stone machinery. The company started developing specialized stone wire saws in 2018 and has since iterated and mass-produced up to the 6th generation. The second-generation wire saw product has been in stable operation for 5 years since it was put into production in 2020. The R&D department of the company has collaborated with multiple research institutions such as Xiamen University and Jimei University, and has obtained over 40 inventions and utility models. The products have been shortlisted for the first set of catalogs in Fujian Province twice, and have received awards and subsidies from relevant science and technology departments at the provincial and municipal levels. In 2023, they passed the product appraisal by experts from the China Machinery Industry Federation, confirming that the technology of Pinhe wire saw products has reached the domestic level.

After the official exposure of the Pinhe wire saw in Shuitou, Fujian in 2022, the product instantly caused a sensation in the industry, receiving unanimous praise from relevant units, research institutions, and customers, and igniting a wave of stone cutting technology. Domestic related enterprises have entered the field to jointly research and explore, making great contributions to the technological upgrading and innovation of the stone industry.
