In addition to the work of metal mold manufacturing parts, it requires sufficient strength and toughness, and its surface performance is also very important to the working performance and service life. The improvement of these properties depends only on the improvement and improvement of the substrate, its role is very limited and uneconomical, and technology can often achieve a multiplier effect, which is also the reason for the rapid development. Mold polishing is an important part of the project and an important post-processing process in the manufacturing process of metal molds.
In addition to the work of metal mold manufacturing parts, it requires sufficient strength and toughness, and its surface performance is also very important to the working performance and service life. The improvement of these properties depends only on the improvement and improvement of the substrate, its role is very limited and uneconomical, and technology can often achieve a multiplier effect, which is also the reason for the rapid development. Mold polishing is an important part of the project and an important post-processing process in the manufacturing process of metal molds. Due to certain problems in domestic polishing technology and materials, a large part of injection molds for point-and-shoot camera lenses, CD, VCD discs, and tools with high transparency requirements still rely on imports.
The mirror mold material is not only a problem of chemical composition, but more importantly, it needs to go through a series of advanced processes such as vacuum degassing, argon protection ingot casting, vertical continuous casting and rolling, soft forging, etc. during smelting, so that the internal mirror mold steel has a series of advantages such as less defects, fine impurity particle size, high dispersion, fine metal grain size, good uniformity, etc., so as to meet the requirements of polishing the mirror surface of the mold steel.
Metal mold manufacturing surface treatment technology is through surface coating, surface modification or composite treatment technology, change the surface of precision mold parts, chemical composition, structure and stress state, in order to obtain the required surface performance of the system engineering. Nitriding processes include gas nitriding, ion nitriding, and liquid nitriding. In each nitriding method, there are several nitriding techniques that can be adapted to the requirements of different steel grades and different workpieces. From the surface treatment methods can be divided into: chemical, physical, chemical and mechanical.
It is worth noting that the surface polishing of metal mold manufacturing is not only affected by the polishing equipment and process technology, but also by the influence of the material mirror, which has not attracted enough attention, that is to say, the polishing itself is limited by the material. Although new treatment technologies aimed at improving surface properties are emerging, nitriding, carburizing and hardened film deposition are mainly used in metal mold manufacturing. Because the nitriding technology can form a surface with excellent performance, and the nitriding process is well coordinated with the quenching process of steel, and the nitriding temperature is low, no strong cooling is required after nitriding, and the deformation is small. Precision mold parts are extremely small, so surface strengthening is an early nitriding technology, and it is also widely used.
Mold is a model, the product is made according to this, but how to produce it, may be in addition to professional, most people can not answer. It plays an irreplaceable role in our lives. Most of the daily necessities are inseparable, such as computers, telephones, fax machines, keyboards, water cups, etc., not to mention plastic products such as automobile and motorcycle engines. Therefore, the role of metal mold manufacturing in modern life is irreplaceable.
