Growing at a fast pace, SDA always attaches great importance to product quality. The 1,500 products put in service have sufficiently demonstrated out quality level with their stable operation. Reliable quality has become one of our core competitive edges that ensure our survival from market competition.
As early as the incorporation of SDA, improvement in product and service quality has been identified as the foundation of our sustainable development. For this purpose, we set up a product quality center to monitor and control product quality throughout the entire manufacturing process. Another fact is that 10% of our employees are testers has many years of testing experiences with medium or senior engineer titles. As a result, we were accredited by quality control system in 2002. Guided by the idea of total quality control, we introduced many advanced supervisor modes and instruments in an active manner to realize PDCA control over each process step specified in quality control programs prepared for individual projects. For each project, we have clearly defined goals and plans for implementation, and we have strict inspection for continuous improvement. By carrying out an accountability system that covers all employees, all process steps and all key factors, we successfully obtained CE accreditation with improving product quality and enhanced quality control. Beginning from 2007, SDA products are exported to the United States and the European Union, which proves that SDA has made a great leap in quality, and that our products are now in compliance with international standards.
