Quality Control

Zibo Domaster has introduced a complete set of testing equipment as well as series of inspection methods in the production lines to guarantee the quality of our porcelain insulator products.

  • Inspection Devices

    Zibo Domaster has introduced a complete set of laboratories and testing equipment, for example, a physical and chemical laboratory was set to test all of the properties of our raw materials, including dimension, mechanical characteristics, and electrical performance, etc. Here are some of the testing devices in Zibo Domaster.

  • Production Process

    Since it calls for high hardness for the rod porcelain insulator, we adopt high-strength alumina ceramic material to produce the insulator.With the 3-stage iron filtering and removing technique, this equipment imported from ERIZE (America) is able to effectively remove the iron powder content in the mixture.
