Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...
The innovation of industry and the improvement of technology have enabled my country’s mold industry to gradually occupy its own position in the entire mold.
At the same time, with the improvement of the quality of my country’s mold products, the domestic mold industry has become the focus of the world, and the market has also moved over. In the future development of the industry, technological innovation is naturally the main one, and technological upgrading is necessary. This is the most important condition for the rapid development of the industry and market demand. Although my country’s mold industry started late, it was mainly low-end products for a long time, but with the gradual transformation, new opportunities for the industry have been in front of us.
At present, the domestic market has a large demand for medium and high-end molds. Among them, the household appliances, automobiles, and plastic products industries have the largest demand for molds. During the Twelfth Five-Year Plan period, the general trend of the mold market is steady and upward, but domestic molds are required to meet the needs of users in terms of quality and delivery time.
In the international market, in recent years, labor costs in industrially developed countries have increased, which is shifting to developing countries, especially Southeast Asian countries. The domestic production of high-precision molds is the mainstay, and the molds with a large amount of labor input are solved by imports. Therefore, the international market potential for medium and low-end molds is huge. As long as the quality of domestic molds can be improved and the delivery time can be guaranteed, the prospects for mold exports are very optimistic. In addition, the demand for national mold standard parts is also great. At present, our country only exports a small amount.
From the perspective of the technological development trend of the machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in my country’s factories will increase year by year, and the demand for high-efficiency advanced tools will increase rapidly. In addition, due to the increase in labor costs in my country, the price advantage of middle and low-end tools will gradually be lost. For the current situation of increasing demand for advanced tools for CNC machine tools, my country’s tool industry must change its concept, vigorously develop the production of high-efficiency advanced tools, pay attention to sales, and pay more attention to after-sales service, and strive to innovate to occupy more market shares.
Technology is always the mainstream trend in the industry, and there are too many obstacles to the development of the industry without innovative technology. I believe that in the days to come, continuous improvement of innovative technologies and independent research and development will become the real mainstream of the domestic mold industry. With the continuous development of my country’s mold industry, the demand and requirements for mold products are gradually increasing. And this kind of improvement has brought greater impetus to the improvement of industry technology.
