"We resumed work and production on February 7, and are currently stepping up to catch up with orders and strive to achieve a 'good start' in the first quarter." He Bo, deputy general manager of the company, told reporters that last year, the company's shipments exceeded 1 billion yuan for the first time, an increase of 31% over the same period last year. This year's orders have also been basically filled, and only full horsepower production is needed at present.
It is understood that Yuhai Precision officially entered the field of laptop supporting in 2011, mainly for HP, Dell and other laptop brands and Inyta, Quanta, Wistron and other manufacturers to support plastic structural parts, with an annual output of more than 20 million sets. "At least 1 in every 10 laptops in the world use plastic structural parts produced by Yuhai." He Bo's tone was full of pride.

He Bo said that the work of the assembly workshop is mainly to assemble the "four-piece set" of the notebook computer shell, the bottom plate, the keyboard frame, and the screen frame, which is colloquially speaking, just like the "soft decoration" for the laptop. In the past, this "soft decoration" was completed by hand, and production efficiency and yield rate were affected. In 2019, the company set up a technology research and development center, set up a professional information and automation team, and in 2020, it established Yuhai Industrial Design and Research Institute Co., Ltd. to improve production process capabilities and production efficiency through scientific and technological innovation.

The reporter saw that on the automated production line of the assembly workshop, the keyboard frame burying operation was underway, only to see the mechanical arm press, a pressure, but 3 to 4 seconds, a single product was buried nails. He Bo introduced that this set of burying nails was independently developed by the company and was officially "put on the job" in March last year. A laptop keyboard frame requires 28 nails, and there are 5 types of nails. In the past, the nails were all manual, and because the nails were too small, they were prone to errors. Now, 5 machines are working in assembly line, and the entire keyboard frame can be completed in more than one minute, which is twice as fast as manual work and the yield rate is much higher.
At present, the company has independently developed and manufactured more than 300 sets of automation equipment, and 55 robots have been introduced. The introduction of OA, ERP, HR, mold MES, molding MEA, assembly MES, WMS, PLM and other information management systems has been implemented successively, and the yield rate has increased from 85% to more than 99%, and the production efficiency has been greatly improved. He Bo said that this year, the company's sales revenue is expected to increase by about 10%.
