The company focuses on the application and innovation of electroplated diamond wire, and creates greater value for the society with its own advantages in large-scale production, research and development, and industrial chain integration. The company's main product is electroplated diamond wire, which is made by uniformly fixing diamond micropowder on a high-strength steel wire matrix with a certain distribution density through a certain method. When working with a diamond wire cutting machine, a high-speed grinding motion is formed between the diamond wire and the object, thereby achieving the purpose of cutting. It is currently widely used in the photovoltaic industry (single crystal and polycrystalline silicon slicing), sapphire, magnetic materials, ceramics, crystal and other hard and brittle materials. Compared with the traditional mortar cutting method, the diamond wire cutting method has high efficiency, high film output rate, less environmental pollution, reduced product damage and lower cutting costs. Compared with the same industry, the diamond particles on the surface of the company's products are evenly distributed, with strong bonding force, stable quality, high overall consistency, strong diamond wire cutting force, high cutting efficiency and low single-piece wire consumption rate. The company has always adhered to technology research and development as the core, and has independent intellectual property rights in the core technology, process control, equipment manufacturing and other links of electroplated diamond wire production. It has mastered a full set of core technologies for diamond wire production including electroplating solution formula, additives, diamond pretreatment, sanding, and online treatment of plating solution. Based on the company's electroplating process and technical advantages, the company's products have strong competitive advantages in stability, cutting quality, process applicability and other aspects. The company maintains a leading position in the research and development of cutting-edge specifications such as 40μm and 42μm.
