What is mold repair

According to incomplete statistics, the annual consumption value of molds in the machining industry is five times of the total value of various machine tools. It can be imagined that the mold market in the machinery, metallurgy, light industry, electronics and other industries is so huge. Another example: in the metallurgical industry, the consumption of hot rolled rolls alone is more than 300000 tons per year, and the value of hot rolled rolls accounts for more than 5% of the steel production cost. The large consumption of molds not only directly increases the production cost, but also causes a large number of production lines to stop production frequently due to frequent replacement of molds, resulting in greater economic losses.
In fact, the failure of molds is due to the wear of local materials on the surface, and the processing cycle of molds is very long and the processing cost is very high (especially the manufacturing and processing cost of precision and complex molds or large molds is as high as hundreds of thousands or even millions of yuan). Therefore, it is undoubtedly a method of great economic significance to strengthen the surface of the specific parts of the mold that are really subject to wear, so as to greatly extend and improve the service life of the mold. In addition, most of the molds will be invalid and scrapped only because of the wear of a thin layer of material on the surface. Therefore, it is only necessary to repair the local wear area of the mold and key metal parts, and apply a layer of high hardness and high wear resistance metal layer on the surface of the mold that actually bears the wear during the repair process, which can "turn waste into treasure", not only to repair the mold, The service life of the repaired mold will also be significantly improved compared with the original mold, with huge economic benefits (for example, it only takes a few days to repair a large shaft of a power plant motor, including various preparation times, using a micro-beam cold welding machine, but it can create millions of yuan of economic benefits).
The mold repair machine is a high-tech equipment for repairing the surface wear and processing defects of the mold. The principle of the mold repair machine is to use the high-frequency electric spark discharge principle to carry out heatless surfacing welding on the workpiece to repair the surface defects and wear of the metal mold. The main feature is that the heat affected area is small, and the mold will not deform, anneal, stress concentration, and crack after repair, ensuring the integrity of the mold; It can also use its strengthening function to strengthen the surface of die workpiece to achieve wear resistance, heat resistance and corrosion resistance of the die.
The die repair machine has long service life and good economic benefits. It can be used to strengthen and repair the surface of various ferrous alloys (carbon steel, alloy steel, cast iron), nickel-based alloys and other metal materials, molds and workpieces, and greatly improve the service life.
Scope of application: machinery, automobile, light industry, home appliance, petroleum, chemical industry, electric power and other industrial equipment manufacturing departments and user departments, key wear-resistant parts of aero-engine, hot extrusion die, warm extrusion film, hot forging die, rolling guide, roll, automobile engine camshaft and other parts and dies
