After 18 Years of Entrepreneurship, He Transformed from 'Competing' to 'Leading'!

During the "Two Sessions" period, at the foot of Sheshan, there is a scientific research pioneer who, for more than a decade, has been at the forefront, striving to consolidate the advantages of the new materials industry and promoting the high-quality development of the Yangtze River Delta G60 Science and Innovation Corridor. He is Wu Haitao, Chairman and General Manager of Kejian Polymer Materials (Shanghai) Co., Ltd.

His career started in a foreign-funded enterprise, where he rose from a technician to a factory director, and finally served as the deputy general manager. The container asphalt primer product he led the development of once held more than half of the global market share, creating outstanding performance. However, to realize his personal entrepreneurial dream and create more valuable products, he decided to resign from his high-paying position and founded Kejian in 2005. After 18 years of hard work, Kejian has become one of the professional manufacturers in the field of global butyl rubber sealants and tapes, with a value of more than 500 million yuan, and has been honored with national-level specialized and sophisticated "little giant", national-level high-tech enterprise, municipal-level specialized and sophisticated enterprise, and other honors. Wu Haitao has been awarded the leading talent in the field of science and technology in Songjiang District and the fifth top talent in Songjiang District, and has served as the executive committee member of the District Federation of Industry and Commerce, the vice chairman of the Sheshan Town Chamber of Commerce, and the chairman of the Association for Science and Technology, among other social positions.     Party-building empowers,deeply plows the track for an "accelerated run"   In 2017, when the company established its Party branch, Wu Haitao submitted his application to join the Party and became a member in October 2019. He firmly believes that only by leading by example and integrating Party building into the development of the enterprise can the cohesion and combat effectiveness of the company be effectively enhanced.     In recent years, the Party branch of Kejian has implemented the "Outstanding Seedling Cultivation Project," strengthening the training of technical backbone. "Party members are like the 'engines' of red color, releasing powerful development momentum, continuously promoting the enterprise to the fast track of high-quality development, and I am the maintenance man of these 'engines'," said Wu Haitao. He often leads the backbone of Party members to the front line of the workshop's research and development to understand the actual difficulties in promoting the project, and to sort out the key issues with the R&D personnel, adjusting the research and development ideas. So far, the company has obtained more than 100 patents and 3 software copyrights, some products have solved the technical "bottleneck," and are in a leading position internationally among similar products.     In 2018, he took the lead in establishing a pioneer team of Party members, which has since won 24 new product innovation awards and applied for 60 patents. In September of this year, a shared laboratory platform for equipment and instruments was jointly built with the Advanced Low-Dimensional Material Center of Donghua University. Wu Haitao was appointed as a high-quality development mentor for "New Materials · New Manufacturing," and together with the university, he has promoted Party building cooperation projects such as the "Innovative Craftsmanship Lecture," "Talent Touchstone," and "Chain Workstation."   People-oriented, Committed to Society's "New Model of Excellence"     Enterprise development must adhere to the people-centered philosophy. Wu Haitao pays great attention to the growth of employees. Under his leadership, the Kejian Party Branch insists on highlighting the orientation of "practicality," taking "solving worries for employees" as its own responsibility, and focuses on coordinating and resolving difficulties in employees' accommodation, transportation, food safety, and other aspects. In addition, he insists on fulfilling social responsibilities, actively participating in the three-year action plan to help poor areas in Songjiang District win the battle against poverty, and the amount of assistance for poverty alleviation, disaster relief, and charity donations has exceeded 500,000 yuan; he has paired up with surrounding residential areas for joint construction, regularly carrying out volunteer service activities such as visits and condolences, and in nearly three years, has organized thousands of people to participate in community volunteer services.

Lean Feast, Wisdom Sharing | A Marketplace Event on Efficiency and Innovation

On March 30th, the second Lean Project Market event was held with great enthusiasm.     Lean management is a customer demand-oriented management approach that pursues excellence and continuous improvement. Its core lies in identifying and eliminating all non-value-added activities and waste to maximize value creation, helping enterprises to enhance overall efficiency. Lean management also emphasizes continuous improvement, which means constantly seeking and solving problems, and continuously optimizing processes. It encourages employees to actively participate, to innovate and solve problems, thereby promoting the progress of the enterprise. Lean management is not just a management tool or technique, but also a corporate culture. It requires enterprises, from top leadership to front-line employees, to uphold the philosophy of lean, integrating the elimination of waste and continuous improvement into their daily work.   Lean Feast, Wisdom Sharing," Kejian Shares' second Lean Project Market event is in full swing. At the beginning of the event, the company's chairman, Wu Haitao, delivered the opening speech.He shared the following three points with everyone:   1. What is lean production? Lean production is all behavior that reduces costs and increases efficiency without changing or improving quality. 2.Why is lean production necessary?

He used this fact happening around us to show everyone the reality of the survival of enterprises in the fierce market competition, hoping that each of us will strengthen the company's core competitiveness with our own efforts. 3.The value that the company has been promoting lean production for three years is: to provide effective value to the entire industry chain and supply chain for Kejian, and to our common bread and butter (our customers), providing important chips in the current severe market environment of involution.   The future development of the company relies either on innovation or lean production. He emphasized the importance of lean production as one of the two legs of the company's development and gave great encouragement to the team's expectations. This was an inspiring opening that set the tone for our day-long event.   Project Exhibition   At the exhibition marketplace, various lean champions showcase the results of their significant lean projects from the past year. This is a rare opportunity for us to get up close and understand the innovative aspects and implementation effects of each project, and also serves as a stage to display the outcomes of team collaboration.
