/ Morning News/July 29, 2022 Guangzhou - On July 29, 2022, the "Beijing Fine Carving Cup" mold Competition of China Mold Industry Association was held in Ningbo, which is known as the "capital of Chinese mold". Hunan Boyun Oriental Powder Metallurgy Co., Ltd. participated in the grand event as the sponsor of "Designated Tool" of China Mold Industry Association. This activity is a professional skills competition in the industry, which not only tests the skills of the participants, but also tests the performance of the "tools", and improves the industry popularity and influence of specialized and special new enterprises.
○ Mold production technology level is an important index to measure a country's product manufacturing level.
Mold is the mother of industry. Mold production technology level is an important index to measure a country's product manufacturing level. According to statistics, 75% of the parts of rough industrial products, 50% of the finished parts and the vast majority of plastic products are moulded.
In recent years, the design and manufacturing level of Chinese molds has been greatly improved. However, as a big country of automobile consumption and production, the precision and surface finish of quench steel molds of large precision high-grade automobile covering parts in China lag behind that of international advanced level, and we mainly rely on imports. Liu Yanjun, Deputy general manager of Boyun Dongfang, said that as a professional manufacturer of high-performance hard alloy with 28 years of technology research and development experience in the industry, Boyun Dongfang high-performance nano hard alloy materials made of cutting tools, can effectively solve the processing problems.
< p> Modern die manufacturing industry has put forward higher requirements for die materials. In order to improve the wear resistance and fatigue resistance of the working surface of the die, the die materials are quenched. The hardened die steel is a typical hard material to work. After heat treatment, the hardness can reach 40-60HRC, and the machinability is poor. The choice of quenched-steel high-speed cutting tool material is very important. Nano carbide tool material can improve the hardness and strength of the tool at the same time, and can be targeted to solve technical problems.
As one of the specialized and innovative "Little giant" enterprises, Boyun Dongfang has been cooperating with Central South University since 2002 to continuously carry out the research and development and preparation of ultrafine/nano cemented carbide through the support of the National Innovation Fund for Small and medium-sized scientific and technological Enterprises and the National High-tech Research and Development Program (863 Program). The expert group led by the academician of the Chinese Academy of Engineering evaluated that the industrial preparation technology of high-performance nano hard alloy developed by the project has reached the international advanced level as a whole, and some performance indexes such as grain size and bending strength have reached the international leading level. The grain size of the nano-carbide WC developed by Boyun Dongfang has reached 0.17μm, which is one of the few enterprises in the world that can produce and sell nano-carbide in bulk. < b> Boyun Dongfang high performance nano cemented carbide materialsBoyun Dongfang has a lot of core competitive products in the industry, such as single/double straight hole rod, double spiral hole rod (30º, 40°), blind hole rod, step rod, multi-layer composite cemented carbide, etc. These products are used in many fields such as aerospace, automobile manufacturing, construction machinery and 3C, and have won unanimous recognition from experts and customers in the manufacturing industry. Our products are mainly for middle and high-end customers around the world, and are exported to many countries and regions such as the European Union, the United States and Japan.
This time, Boyun Dongfang also exhibited highly competitive high-performance hard alloy mold materials. It is reported that Boyun Dongfang and Ningbo Zhenyu have been strategic cooperation for many years, the two sides collaborate on innovation, and continue to provide customers with professional solutions, which has won the unanimous praise and recognition of customers. Deputy General Manager Liu Yanjun also said that, relying on the strong scientific research and technology strength of Central South University and the technical team of Academician Huang Boyun, Boyun Oriental adheres to the concept of "innovation makes dreams come true", constantly boosting the technological development of the hard alloy industry and solving the "bottleneck" key technical problems. Strive to become the world's high-end hard alloy technology leader.
