Mechanical transmission equipment has been used for a long time, resulting in increased power consumption, increased vibration, increased noise, leakage pollution and other problems, resulting in work failure or shutdown accidents. For large or imported equipment, there is often a lack of spare parts, high added value, long switching cycle and huge economic losses.

Most of the mechanical equipment and its parts are damaged or scrapped, only some parts are worn, corroded, oxidized, scratched, deformed and lose their original size and performance, so they can no longer be used directly. Therefore, through remanufacturing technology to repair the worn and corroded parts, maintain and repair the machine, and achieve the purpose of restoring or even exceeding the original machine performance. This repair technology has the advantages of low energy consumption, low cost and short cycle, which is of great significance.

In view of the current situation of imported high-precision and large-scale gear box transmission equipment used by many large chemical multinational companies around Ningbo, the company cooperates with domestic first-class scientific research institutions, such as Ningbo Branch of Academy of Military Sciences on anti-corrosion and coating of parts, Zhengzhou Institute of machinery on high-precision gear manufacturing, Harbin Institute of Technology on motor control, and Ningbo University on performance testing Cooperation, and so on, in terms of remanufacturing technology, has achieved actual results over the years. The picture shows the company solving the problem of gear strength defect of the former German extruder gearbox for LG Yongxing Chemical Co., Ltd. of South Korea through remanufacturing technology.

At present, the company has carried out a lot of practice in the "ultrasonic spraying cermet coating technology", "laser quenching and welding technology", "pneumatic hydraulic nondestructive disassembly technology", "nano material brush plating technology", and achieved practical results.
