According to incomplete statistics, the annual consumption value of molds in the machining industry is five times the total value of various machine tools. It is conceivable 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 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 frequent economic shutdowns due to frequent production line shutdownsChina Plastic Pallet Moulds Manufacturers caused by frequent replacement of molds. The failure of the mold is actually scrapped due to local surface material wear and other reasons, and the processing cycle of the mold is very long and the processing costs are extremely high (especially the manufacturing and processing costs of precision and complex molds or large molds can reach hundreds of thousands of yuan or even millions yuan). Therefore, it is undoubtedly an economically significant method to strengthen the surface of a specific part of the mold that is really subject to abrasion to greatly extend and increase the service life of the mold. In addition, most of the molds are scrapped because they are worn by a thin layer of material. Therefore, it is only necessary to repair local areas of mold and key metal component surface wear, and actually repair the mold surface during the repair process. If the surface is coated with a high hardness and high wear-resistant metal layer, it can be turned into a treasure. Not only will the mold be repaired, but the service life of the repaired mold will also be greatly improved compared to the original mold. : It only takes a few days to repair a large-scale motor shaft of a power plant motor, including various preparation times, but it can create millions of yuan in economic benefits). Mold repairing machine is a high-tech equipment for repairing mold surface wear and processing defects. The principle of the mold repair machine is to use the high-frequency electric spark discharge principle to perform non-thermal overlay 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, not anneal after repair, No stress concentration and no cracks ensure the integrity of the mold; it can also use its strengthening function to surface strengthen the mold workpiece to achieve mold wear resistance, heat resistance, corrosion resistance, etc. The mold repairing machine reinforces the mold for long life and good economic benefits. It can be used to strengthen and repair the surface of various metal-based molds and workpieces of various iron-based alloys (carbon steel, alloy steel, cast iron), nickel-based alloys, etc. and greatly increase the service life. Applications: machinery, automotive, light industry, home appliances, petroleum, chemical, power and other industrial equipment manufacturing departments and use departments, key wear parts of aviation engines, hot extrusion dies, warm extrusion film, hot forging, steel rolling Guides, rolls, automotive engine camshafts and other parts and molds
