They have the enthusiasm of selfless work, selfless dedication and excellent professional skills. They are hardworking, dedication, and make extraordinary contributions in ordinary positions. They all have a common name called "model workers." May 1st International Labor Day is approaching, this newspaper has specially opened a "labor style" column, taking you into the grassroots, approaching the model workers, understanding their professionalism and touching stories, hoping to pass the role of their demonstration to convey the spirit of the model. More people have contributed to the construction of Zhengzhou International Commercial Capital.
For a technological innovation, the drawings were revised and tested five or sixty times in a row; in order to satisfy the customers, the operation of the products was tracked 24 hours a day, seven days and eight days. Under his leadership, his team created two invention patents, with sales exceeding 12 million yuan in 2015. He is Sun Jianfeng, general manager of Henan Province, and general manager of Precision Diamond Mould Division of Henan Sifangda Superhard Materials Co., Ltd.

Dedicated to devote yourself to technological innovation
When he first arrived in the company in 2005, Sun Jianfeng was only an ordinary worker in the grinding workshop. He loved his dedication, focused on the combination of theory and practice, and observed the operation status of various types of machinery in the workshop. How can he improve the performance of the machine and improve it? Capacity.
In 2006, when Sun Jianfeng worked in the workshop, he often heard colleagues reflect that the grinding equipment at that time was inconvenient and inefficient. Sun Jianfeng has done countless experiments and deployments in two years. Finally, the brake method was changed from manual weight to pneumatic pressure, which improved work efficiency by 50% and saved the company 400,000~500,000 yuan a year.

Invention patents fill the gap in the domestic market
For Sun Jianfeng, the workshop is the most attractive place. As soon as he has time, he will go to the workshop and look for cracks in all kinds of intractable diseases.
In 2012, Sun Jianfeng discovered that the tungsten steel materials used in the original peeling abrasives not only cost high, but also wear quickly, which inevitably increases the production cost of the enterprise. He led the team through a lot of research and experiment, and finally replaced the tungsten steel material with polycrystalline material, which increased the wear resistance of the abrasive tool by 30~50 times, and saved the manufacturer more than 1 million yuan of raw material cost every year. After the patent was introduced to the market in 2013, it filled the gap in the domestic market.
In order to make the new improved peeling abrasives better adapt to the market, Sun Jianfeng personally followed the manufacturer to understand the actual use of the abrasive tools, and sometimes followed the customer for seven or eight days and tracked the operation of the products for 24 hours. After unremitting efforts, the improved peeling abrasives were highly recognized by the manufacturers, and the market share exceeded 70% that year.
Over the past 11 years, Sun Jianfeng has grown from an apprentice to a business backbone with a spirit of forge ahead and selfless dedication. The R&D team he led has successfully developed a series of high-quality products.
At present, the business department has 2 effective patents, and the sales in 2015 exceeded 12 million yuan, making outstanding contributions to the development of the company.
