Product Manufacturing Process

The manufacturing process of our porcelain disc insulators involves a rigorous method to ensure high standards of quality. It starts with the careful selection and mixing of raw materials. The raw material mixture is shaped into blanks and then dried adequately. The dried blanks are glazed to create a smooth surface and are then heated in a kiln to achieve vitrification. Post-kiln, the insulators undergo glue assembly followed by routine and other quality tests to ensure compliance with safety standards. The final product is meticulously packaged to protect against damage during transit.
