In the golden autumn of 2024, Broater-benda received on-site supervision from TÜV Rheinland Testing and Certification Services. The entire supervision process was tense, orderly, candid, and effective. The previous work was recognized and encouraged by the supervising teacher, while also pointing out some gaps in some aspects, which provided direction for the further improvement of Broater-benda 's quality and management. The company will further improve relevant processes to lay a solid foundation for providing better products and services.
