In the quality control system of our drone countermeasure factory, quality certifications play a fundamental and crucial role. We have successfully obtained several authoritative and stringent quality certifications. Among them is the ISO 9001 Quality Management System Certification, which comprehensively covers every aspect of our operations, from the research and development and design of drone countermeasure equipment, the precise screening and procurement of raw materials, to the meticulous manufacturing process, the rigorous inspection of finished products, and the efficient after-sales maintenance services. It ensures that each process has standardized and regulated operating guidelines and key points for quality control, making every drone countermeasure device leaving our factory highly stable and reliable. Meanwhile, we also hold the ISO 14001 Environmental Management System Certification. During the production process, we strictly adhere to environmental protection requirements. From the energy consumption management of equipment to the proper disposal of waste, we conduct scientific planning and control to achieve green production. Moreover, in view of the special field of drone countermeasure, we actively obtain relevant professional certifications. For example, we have certifications in electromagnetic compatibility to ensure that the equipment can operate normally in complex electromagnetic environments and will not cause interference to other surrounding electronic equipment. There is also the reliability certification. Through simulating various extreme environments and working conditions to conduct long-term tests on the equipment, we verify its durability under different scenarios. These quality certifications jointly build a solid quality defense line for our drone countermeasure factory, enabling our products to win high trust and wide acclaim from customers in both domestic and foreign markets, and effectively guaranteeing the effective implementation of important application scenarios such as public security and airspace order maintenance.
