Quality Control

We believe that only high quality and excellent service can bring us lasting business.After 15 years of development,we have formed a mature quality control system from raw materials to finished products.All our raw materials come from fixed suppliers,and we will test their materials.Only if they pass the test can they become our cooperative suppliers,In addition ,we also carry out sampling inspection on each new batch of raw materials.
