Associate Professor Yong Zhanfu of the School of Polymer Science and Engineering of Qingdao University of Science and Technology, with his profound attainments in the fields of polymer material fatigue life prediction, rubber mechanical simulation and software secondary development, recently visited Demeirui Mechanical Seals Factory in Julu County, Hebei Province for in-depth technical guidance. This exchange is not a simple visit, but a key action to inject strong momentum into the future development of the factory and clarify the path of technological upgrading, which significantly enhances the core competitiveness of the enterprise.
On-site diagnosis, indicating the direction of process optimization and quality improvement:
In Demeirui's production workshop, Professor Yong went deep into the front line and carefully inspected the entire process of rubber seals from raw material processing, mixing, molding to vulcanization. With a deep understanding of the relationship between the microstructure and macroscopic performance of polymer materials, he accurately pointed out the key process nodes that affect the stability and final performance of product batches. For example, for core links such as mixing uniformity and precise control of vulcanization process parameters, Professor Yong provided specific optimization solutions based on materials science. These suggestions directly target production pain points, which not only help Demeirui to immediately improve the stability and consistency of existing product quality, but more importantly, point out a clear technical roadmap for it to establish a refined production system for high-performance and long-life seals.

Process upgrade:
Professor Yong diagnosed the production process on the spot, and proposed optimization solutions based on material science for key links such as mixing and vulcanization, which significantly improved the stability and life of product quality, and pointed out the technical path for the production of high-performance seals.

R&D empowerment:
In the laboratory, he proactively guided the establishment of accelerated fatigue testing and complex working condition simulation capabilities, and emphasized the use of experimental data to correct simulation models. This lays the foundation for the factory to directly apply Professor Yong's team's advanced fatigue life prediction technology and customized simulation tools (such as UMAT secondary development) in the future, turning simulation into a research and development tool.
Clear direction:
This guidance clarifies the core direction for Demeirui - from experience manufacturing to data-driven and simulation-led precision R&D manufacturing, focusing on improving the long life and adaptability of products to complex environments.
Solid backing: Professor Yong and his team from Qingdao University of Science and Technology have become a strong technical support and knowledge source for Demeirui, ensuring that it can continue to obtain cutting-edge technical support and clarifying a high-quality development path driven by scientific and technological innovation.

Associate Professor Yong Zhanfu's guidance is like lighting a bright light for Demeirui Mechanical Seals Factory, which not only solves the current technical confusion, but more importantly, relying on the strong academic resources of Qingdao University of Science and Technology, it has planned a clear path for it to lead development with science and technology and drive the future with innovation, so that Demeirui has unique technical advantages and a clear development direction in the fierce market competition.
