Hebei Guoning Company Participates in Coated Sand Technology Seminar
From September 25 to 26, 2025, the 69th Session of the Specialized Seminar on Key Technologies for Precoated Sand Casting Production and Case-based Defect Analysis, hosted by Puyang Baizhu Media, was held in Jinan, Shandong Province. Hebei Guoning Company organized personnel to attend the seminar, aiming to refine its precoated sand technology and promote its independent precoated sand equipment production lines.
This seminar focused on the core technical pain points in precoated sand casting production and defects in practical cases. It invited a number of domestic experts in the casting industry and senior technical engineers to give on-site lectures. The expert team conducted in-depth sharing on key topics such as the selection of precoated sand raw materials, the optimization of sand mixing processes, the cause analysis and solutions for casting defects (e.g., sand holes, gas holes, cracks), and the application of intelligent production equipment. They also explained and analyzed a large number of frontline production cases in detail, providing highly practical technical guidance for the participating enterprises.
During the seminar, the participants from Hebei Guoning Company actively engaged in the discussions throughout the entire process, listened carefully to the experts' explanations, and conducted in-depth exchanges with peers and experts on the precoated sand process problems encountered in production. By observing the analysis of typical cases on site and participating in technical salon discussions, the team systematically sorted out the technical key points of each link in precoated sand production, further mastered advanced defect prevention and control methods and process optimization ideas, and laid a solid foundation for the subsequent technical upgrading and process adaptation of the company's precoated sand equipment production lines.
At the same time, the company promoted its precoated sand equipment through various methods and introduced its advantages such as intelligent control, high efficiency and energy conservation. This attracted the attention of participating enterprises and led to technical consultations and cooperation intentions in various aspects.
Through this participation, Hebei Guoning Company not only improved its process capabilities but also expanded its equipment promotion channels. Looking forward to the future, the company will continue to take technological innovation as the core, optimize equipment performance, and contribute to the high-quality development of the casting industry.
