All analyses are clearly demonstrating that there is no structural, mechanical, or di-electrical difference between Alumina Porcelain Insulators manufactured by Isostatic or Plastic Process.

The Alumina Porcelain Insulators are traditionally manufactured so-called “Plastic” Process”, as well called “Conventional” or “Wet-Process”. This process has the same steps as the process developed in China during the Shang Dynasty (1600–1046 BCE).

The Isostatic manufacturing Process was developed in the 70’ties for the needs of Powder Metallurgy.
