Construction machinery parts need to improve product reliability

At present, domestic engineering machinery and accessories are mostly at the low-end level, and the echelon that has entered the high-end core technology level is undoubtedly a huge challenge to most Chinese SMEs. With eagerness to break through, it is difficult to find exports, and many domestic companies have therefore fallen into a dilemma.

In addition to the constraints of key technologies, another important aspect of the gap between China's construction machinery parts and foreign products lies in its reliability. The production of 10 pieces and 8 pieces in small batches is reliable, and the quantity is unreliable. Product reliability is related to management, process equipment, and process routes. In general, the factors that currently affect the reliability of Chinese components are mainly raw materials, especially the quality of steel products. Domestic construction machinery enterprises are generally not large in size and require special purchases from steel mills. Others ignore them. There is also a gap between technology and equipment and foreign countries. There are flexible production lines abroad and each program has strict controls. There are also problems with heat treatment. The reliability of the kits produced in this way is not good, which leads to the inability of the host to improve its quality. Reliability problems are not resolved, domestic kits are sold cheaper, and users will not buy it.

In order to get into the high end of the local construction machinery parts, we must first get rid of the defects in the lack of product quality stability, and strive to improve the core technology. The seamless connection with top-ranking companies in the world, and the blind and large area of ​​spreading the net, are obviously a bit "terrible." The development and growth of any country's manufacturing industry will undergo a difficult process, and its own degeneration and creation of enterprises will only be down to earth!
