After-sale Service

Our quality control is set up according to the quality system requirements of ISO 9001:2000. Our quality control consists of three components: incoming inspections through which we ensure the quality of the raw materials that we source from third parties, in-process quality control of our manufacturing processes, and output quality control of finished products through inspection and by conducting reliability and other tests.

 

We had passed international certification requirements and continue to upgrade our product quality with proven technologies. Quality is one of our core values and the pursuit of quality will continue to drive the company's efforts in the future as it continues to upgrade its products.

 

Our ISO, UL, TUV, CE, IEC, ICIM certified modules proof of our international standards for product safety, durability and overall quality.
