Factors affecting the tool purchasing power of the mold industry

Editor's note: In recent years, with the development of the mold manufacturing industry, the requirements for the mold part material itself have been increased. Superhard cutting tool materials such as CBN (cubic boron nitride), PCD (polycrystalline diamond) tools and new carbide tools have been With a large number of tools, the consumption and purchase of tools have become a topic of common concern for mold manufacturers and tool manufacturers.

The application of the integrated tool According to the investigation of Luo Baihui, the secretary-general of the International Model Association, among the tool materials selected by the domestic mold users, the most used tools are carbide tools, accounting for 64.1%. With the development of super-hard tools, hard turning is gaining popularity as a good alternative to grinding economics. The use rate of super-hard tools has been significantly improved. For example, machining of cylinder bores uses cubic boron nitride inserts in many semi-finishing and fine boring operations. Cutting speeds reach new heights, and tool life is greatly extended. The tools that can be indexed have been promoted in China for many years and have progressed smoothly. However, the development is still unbalanced, and the user coverage is still lower than the overall tool and welding tool. However, the technology of indexable cutting tools in our country has made new progress in the promotion process, and there is great potential for rapid application of varieties.

The rapid development of modern tooling manufacturing machinery processing and the use of cutting tool technology, high-tech has been widely used, in the processing technology, cutting methods, tool structure, tool materials, tool coating and other aspects have been with the traditional mechanical processing Different points. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate CNC machine tools and tool holders for high-speed machining and their connection to machine tools such as HSK holders, hot-set holders, hydraulics Tool holders and other new tool holders are widely used. In order to increase production efficiency and reduce tool change time, various compound tools, such as drill boring compound, drill reamer compounding, drilling and thread machining compounding, are increasingly used in the processing of mold parts. The unfolding tool satisfies many special machining requirements, and some tools have even developed into a machine, electric, and hydraulic integrated device, which has far exceeded the concept of a traditional tool.

Mold tool consumption characteristics of the mold industry In order to achieve lean mold production, mold companies scientifically organize tool procurement and inventory management, need to study and explore how to ensure the normal operation of the production line to reduce tool inventory capital occupation, optimize the tool's minimum inventory settings The procurement starting point of the tool, the reasonable purchase frequency of the tool and the purchase volume, the establishment of an effective tool warning mechanism, emergency mechanism and rapid response mechanism, there are scientific and effective methods to track, monitor tool inventory status and purchase status. It is understood that 68.5% of the users of the company account for less than 3% of the total cost of tool costs, and the manufacturing cost of manufacturing tools in developed countries, which accounts for about 4% of the cost of production, constitute a big gap, which is also caused by the low level of Chinese manufacturing cutting One factor.

China's mold industry is related to the phenomenon of decentralization, low-scale, and low-level phenomena. China's mold manufacturers are among the largest in size, and the rest are mostly small and medium-sized. These conditions determine the characteristics of the tool users in the mold industry: the purchase volume is increased, and the number of purchases is frequent, that is, it can be purchased once every two months or so. This reflects that the consumer market is relatively mature, and tool users in the mold industry are more inclined when making budgets. For flexibility, rather than keeping too much inventory. At the same time, due to the flexibility of user procurement, the market offers ready access to those who have not yet entered the tool suppliers. As a result of on-demand procurement, the competition for mutual replacement of used brands is also increasing.

The factors that influence the purchasing power of the tool The user pays more attention to the improvement of efficiency and the optimization of input-output ratio rather than the simple price factor. The connotation of "service" has evolved from simple pre-sales and after-sales service to the solution of cutting plans.

The performance and quality of the tool directly affects whether or not the required qualified products can be processed smoothly. The tool can meet the requirements of high-speed cutting. The tool life and the frequency of tool change directly affect the production line activation rate, affecting the processing cycle and production efficiency. The ability to supply adjusted or polished tools to the production line on time and with a guaranteed quality will directly affect the ability of the production to continue normally. Therefore, Luo Baihui believes that the use of cutting tools for tooling users in the mold industry mainly considers: cutting efficiency is the most important, followed by the service life, and the service factor has been given more attention. The tool manufacturing companies have also introduced various measures to complete the production together with the purchase of knife companies.
