Carbide is widely used in the mold manufacturing field due to its high hardness, wear resistance, and impact resistance, playing an irreplaceable role especially in scenarios such as stamping, drawing, and powder metallurgy. However, not all carbide materials can meet the demands of high-end molds. As a source manufacturer of carbide, we have summarized the following five core elements—from material composition and process control to end applications—to help users select truly high-quality mold materials.

Renqiu Hengrui Carbide Co., Ltd. is located in the Shizhuang Industrial Zone, Renqiu City, Hebei Province, adjacent to the "Pearl of North China" Baiyangdian Lake 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 fully integrated specialized carbide company that encompasses product R&D, 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, and more, 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 markets in Europe, America, and the Middle East. 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 a few 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, metallography, and bending strength to ensure every product meets quality standards.
