The auto-spray label equipment of oil tubing factory was brought in 2004. It was advanced equipment and the performance was excellence at that time. However, as the high-tech involve, the staffs inOil Tubing Factorycouldn’t repair it without specialist once it broken down, which caused long time delay of production process. In recent years, the nozzle blockage problem was seriously. Once it is blocked, it has to send to Guangzhou for repairing which cost a lot. If it does not receive proper maintenance, it will block again and affect the quality of labels. The Oil Tubing Factory was looking for a reasonable solution.

Zhitao Wang is an ordinary painter in the factory. He thought this through work and invented new auto-spray label equipment with the help from other co-workers. The auto-spray device does not need to use the special paint which is expensive, and the design cut down more than ten motors in use which reduced the power consumption, and saved the cost. By estimation, this invention can save 150,000 each year at least. A small invention really brought great benefits.
