    According to incomplete statistics, the annual consumption value of molds in the machining industry is five times the total value of various machine tools, and it can be seen that the mold market in machinery, metallurgy, light industry, electronics and other industries is so huge. Another example: in the metallurgical industry, the annual consumption of hot rolled rolls alone is more than 300,000 tons, and the value of hot rolls accounts for more than 5% of the production cost of steel.

    The large consumption of molds not only directly increases production costs, but also causes a large number of production lines to be frequently shut down due to frequent replacement of molds and tools, which becomes a greater economic loss.

    In fact, the failure of the mold is scrapped due to the wear and tear of the local material on the surface, and the processing cycle of the mold is very long and the processing cost is extremely high (especially the processing cost of precision complex molds or large molds is as high as hundreds of thousands of yuan or even millions of yuan). Therefore, it is undoubtedly an economically important method to strengthen the surface of the specific parts of the mold that really bear the effect of wear to greatly extend and improve the service life of the tool. In addition, most of the mold only because the surface is very thin after the material is worn and scrapped, therefore, only need to repair the local area of the surface wear of the mold and key metal parts, and in the repair process, the surface of the mold that really actually bears the wear is coated with a layer of high hardness and high wear-resistant metal layer, you can "turn waste into treasure", not only make the mold repaired, the service life of the repaired mold will be greatly improved compared with the original mold, and the economic benefits are huge (for example

    It only takes a few days to repair a large shaft of a power plant motor, including various preparation times, with a microbeam cold welding machine, but it can create millions of dollars in economic benefits).

    Mold repair machine is a high-tech equipment for repairing wear and tear on the surface of the mold and processing defects. The principle of the mold repair machine is to use the principle of high-frequency electric spark discharge to carry out non-thermal 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, the mold will not be deformed, annealed, stressed without concentration, and there will be no cracks after repair, so as to ensure the integrity of the mold; It can also be used to strengthen the surface of the mold workpiece by its strengthening function to achieve wear resistance, heat resistance, corrosion resistance, etc.

    The mold repair machine strengthens the mold with long life and good economic benefits. It can be applied to various iron-based alloys (carbon steel, alloy steel, cast iron), etc., nickel-based alloys and other metal materials, molds and workpieces for surface strengthening and repair, and greatly improve the service life.
