At present, the domestic engineering machinery accessory products are uneven in terms of technology, quality and technical level. The product technology is mostly at the middle and low end level, and the echelon of entering the high-end core technology level is undoubtedly a huge challenge for most small and medium-sized enterprises in China. Being eager to break out of the encirclement, it is difficult to find exports, so many domestic enterprises are in a dilemma.

In addition to the constraints of key technologies, another important aspect of the gap between China's construction machinery accessories and foreign products is their reliability. The small batch production of 10 and 8 pieces is reliable, but it is not reliable if the quantity is more. Product reliability is related to management, process equipment and process route. In general, the main factors affecting the reliability of China's components are the quality of raw materials, especially steel. Domestic construction machinery enterprises are generally not large, and they ask steel mills for special purchases, which is ignored by others. There is also a gap in technology and equipment with foreign countries. Foreign countries have flexible production lines, and each procedure is strictly controlled. There are also problems with heat treatment. In this way, the reliability of the produced parts is not good, which leads to the inability to improve the quality of the host. If the reliability problem is not solved, users will not buy any cheaper domestic accessories.

In order to enter the high-end market, local engineering machinery accessories should first get rid of the defect of insufficient product quality stability, and strive for perfection before tackling the core technology. Seamless connection with international first-class enterprises, and blind large-area casting of nets is obviously a bit "thankless". The development and growth of the manufacturing industry in any country will go through a hard process. The only way is to be down-to-earth and create enterprises through self transformation!
