The HR00 series carbide cold heading dies are high-performance mold products independently developed by our company, specifically designed for the cold heading forming process of fasteners and hardware components. They are suitable for various application scenarios such as straight rod dies, reducing dies, and cap forming dies. This series of molds utilizes high-quality alloy materials and advanced heat treatment processes, offering extremely high hardness, wear resistance, and impact resistance, significantly extending the mold's service life while ensuring stable processing accuracy.  

Renqiu Hengrui Carbide Co., Ltd. is located in Shizhuang Industrial Zone, Renqiu City, Hebei Province, adjacent to the North China Pearl Baiyangdian and the Xiong'an New Area, covering an area of 12,000 square meters. Since entering the carbide industry in 2000, the company has evolved from initially distributing carbide products to becoming a full-chain specialized carbide company integrating product development, manufacturing, online and offline sales, and after-sales service.

Our company mainly produces cold heading dies, nail making dies, progressive dies, carbide plates, carbide nozzles, carbide ball mill jars, roll rings, valve cores, valve seats, etc., which are used in various fields such as mining, oil extraction, electronics, automotive, and military industries. Our products are distributed throughout the coastal regions of Jiangsu and Zhejiang and are exported to European, American, and Middle Eastern markets. We have a high-tech R&D and production team, having developed over 40 independent brands and holding four national patents. We have passed ISO9001 certification, ISO2000 certification, and the China Credit Enterprise System certification. Products ranging from one or two grams to hundreds of kilograms are all produced using HIP sintering equipment and the Hughes sintering process from the United States. Scientific testing and analysis are conducted on indicators such as hardness, density, coercive force, magnetic saturation analysis, metallography, and bending strength to ensure every product meets quality standards.https://www.rqhtrx.com/
