Shuangchao Machinery is constantly working to improve the technical training system for service engineers. Over the years, we have invested more and more in training facilities. Shuangchao headquarters has a well-equipped maintenance training workshop, maintenance equipment, imported test tools and training vehicles. In addition, a rigorous training and assessment system has been established to ensure the skills of service engineers. At the same time, we have accumulated rich experience in tool design, procurement, management, and optimization. The standardized clothing, tools, and service vehicles of the Shuangchao service team have become a powerful driving force for the secondary technological revolution of Shuangchao Machinery. The introduction of the call center service model with a national unified after-sales hotline allows customers to more directly feel the convenience, speed, reliability and effectiveness of Shuangchao's technical services.
