On August 13, 2025, Mr. Ye Junjie, a mechanical seal expert from Zhangjiagang Keruitao, visited Root Corporation and delivered a training session on mechanical seal knowledge for production and technical personnel. Factory Director Zhu Jiagui, Quality Director Wu Xianglong, as well as staff from relevant departments, participated throughout the entire session. This training aimed to improve the professional technical competence of the production team and further enhance product quality.

This training adopted a dual-mode approach of "theoretical teaching + on-site guidance". Mr. Ye systematically explained the structural principles, key selection criteria and maintenance standards of mechanical seals, with a particular focus on an in-depth analysis of the technical difficulties in dynamic sealing for grinding equipment.Subsequently, he went deep into the production workshop, conducted on-site demonstrations combined with actual equipment, and provided hands-on guidance on practical key points such as seal installation, commissioning and troubleshooting. This enabled the trainees to gain a more profound understanding of mechanical seal technology.



As a national-level specialized, sophisticated, and innovative "little giant" enterprise, Root Corporation has always attached great importance to technological innovation and talent development. Going forward, the company will continue to deepen cooperation and exchanges with industry experts, so as to provide customers with higher-quality products and services.
