On September 3, 2020, the production department received a notice: a total of 4 fans from customers in Beijing and Dalian were in urgent need of assembly, test and delivery. After receiving the notice, the production organized the assembly workshop to prepare materials. In the process, it was found that the motor of a customer in Beijing did not arrive. General Manager Li Yang actively coordinated with the motor factory, and Logistics center Li Yongping contacted bicycle delivery, and the motor was delivered to our factory at 1:30 a.m. on September 4th. As the rated current of the motor customized by the dalian customer is 678A, if all the equipment in the factory is tested, the production will be delayed. Production Minister Wang Hejun requires the assembly workshop to complete the assembly in the evening and transfer it to the test center for testing at 5:00 in the morning, so as not to delay the production of the workshop. Huo Chong, the squad leader of the assembly workshop, adjusted the assembly order according to the instructions of the production department, organized the team to assemble the fans of the customers in Dalian in advance, and the whole class worked overtime until 8 o 'clock on the evening of 3rd, and contacted Zhao Guocai, the forklift driver of the logistics center. Zhao hurried to the unit from home and transferred the fans to the test center. Huo Chong, the squad leader of the assembly workshop, and Jin Xin, the team member, continued to work overtime until 7 o 'clock on the morning of 4th, and finished assembling the remaining fans of customers in Beijing and Dalian. Wang Hejun, director of production, and Sun Aihua, electrician, went to the unit to test the fans at 5 o 'clock on the morning of 4th. The four fans completed the test at 7:30 o 'clock on the morning of 4th and were transferred to the painting site, which ensured the smooth delivery of products and the smooth progress of production.
