Zhuzhou Precision Diamond "High-precision ultra-fine carbide micro-hole drawing die" high

For many businesses, having their own core competition is a very important thing. Having mastered the core competition technology can achieve a multiplier effect. Even if it is copied or copied, it has its own independent formula technology, even if The appearance is the same, but from the use of the effect can be a sharp contrast, so businesses to ensure their own original product technology, but also need to continue to innovate and improve their core competitiveness.

Recently, Zhuzhou Cemented Carbide Group Co., Ltd. completed the "Research and Development of High-Accuracy Ultrafine Carbide Microporous Drawing Cores" project and passed the provincial appraisal. The appraisal committee with the chairman of the Chinese Academy of Engineering, Huang Boyun, believes that the overall technology of the project has reached the international advanced level.

Carbide micro-hole drawing die is mainly used for drawing various metal wire drawing die of 0.1-1.0 mm in diameter, such as tire steel cord, cutting steel wire, hose wire and niobium wire, molybdenum wire and other non-ferrous metal filaments. Wait. All along, due to material reliability, dimensional accuracy, etc., the high-end market for high-speed carbide wire-drawing wire-drawing die products for high-speed wire drawing in China is basically dependent on imports.

Zhuzhou Cemented Carbide Group Co., Ltd. independently developed the "high-precision ultra-fine carbide microporous wire drawing core" technology, to overcome the technical bottleneck of the traditional process inhomogeneity, through the precision mold design and hole optimization research, to prepare the most A microcavity wire drawing core with a small cavity inner diameter of 0.08 mm.

The products of this project have been inspected by China Nonferrous Metal Industry Carbide Quality Inspection Station. The quality is in line with the Q/OHNG 013-2013 standard. The main performance indicators are equivalent to the international advanced level. The appearance geometric parameters and concentricity tolerances have reached the international advanced level. To meet the market demand for high-speed drawing wire rods with hard alloy microporous wire drawing cores, the economic and social benefits are significant.
