Ten years of unwavering dedication is a relentless pursuit of technology, a guarantee of product quality, and a continuous challenge to oneself. He is the young technical model who quietly holds his post in the technical field—the engineer Sun Miao from the R&D Center of the Automotive Control Division. With the loyalty, responsibility, and focus of a Communist Party member, he practices his values in an ordinary position, working diligently on the front line of expansion valve R&D since joining the company, embodying the company's spirit of “diligence” and “integrity” in the younger generation.
Sharpening a sword in ten years is a true portrayal of a technician. Since joining in June 2010, Sun Miao has worked diligently in his technical position, continuously overcoming technical challenges and ensuring the consistent quality of automotive expansion valves for ten years. Thanks to his persistence, there have been no major technical issues with the expansion valves, and in product maintenance, he has continuously improved drawings and optimized product structures, resulting in significant performance improvements compared to before.
Due to structural issues with the expansion valve, the high defect rate of superheat has always been a major concern, and the production pass rate has been unsatisfactory, leading to significant waste during production over time. After learning about this issue, Sun Miao began to study the root causes, carefully analyzing the drawings and striving to solve the problem structurally. Hard work pays off; after more than a month of overtime analyzing drawings, conducting experiments, and improving processes, he greatly increased the pass rate of superheat, thereby significantly reducing production waste.
Whenever asked how he managed to persist for so long, he always smiles shyly and says that dealing with drawings every day has made him thoroughly familiar with every aspect of them. Sometimes, a structure that looks normal at first glance always seems off upon reflection, which gives him the drive to correct it—this is probably the charm of technology. While improving existing products, Sun Miao also actively participates in new product development. With the popularization of new energy electric vehicles, the mechanical expansion valve's function can no longer meet the needs of electric vehicles, so he began participating in the development of a new type of expansion valve. Compared to mechanical expansion valves, the new expansion valve is better suited for use in new energy electric vehicles, and it has now been successfully developed and mass-produced.
While developing new products, Sun Miao also leverages his strengths and focus as a technical engineer to actively assist the workshop, offering multiple reasonable suggestions for lean production and process improvement. “A single flower does not make spring, but a hundred flowers in full bloom bring spring to the garden.” As an "elite model" in the technical team, mentoring new employees is also his unshirkable responsibility. In the words of the new generation of technical engineers he has personally trained: "Engineer Sun is approachable in every way, but when it comes to business, he is a tough professional."
“A good technical engineer must reassure leaders, earn employees” recognition, and satisfy customers." This is Sun Miao's own definition of a qualified technical engineer, and he works hard for it every day, perseveres for it, and takes pride in it.
