The Production process flow:

The production process of glass insulators in Jiangxi Huayao Electric Co.,Ltd is as follows:

Mix raw material=>melt glass liquid=>press to glass insulator shape=> tempering treatment=>cold and shock test=> Glue assembly=> routine test and other test=> Finished products package

Ingredients: Ingredients refer to the uniform mixing of different raw materials according to a certain ratio.

Melting: Melting refers to the process of heating ingredients at high temperatures to form a uniform glass liquid.

Pressing: After melting and clarification, the glass liquid enters the pressing process through the feeding system, that is, the glass is hydraulically made into glass insulation parts, usually achieved through a fully automatic hydraulic forming machine.

Tempering: Subsequently, the glass piece is subjected to tempering treatment, which means controlled cooling of the glass piece to obtain permanent surface press tress. The equipment involved in the tempering process includes temperature equalization furnaces, tempering machines, etc.

 

Cold and hot shock: Tempered glass pieces undergo cold and hot shock tests, using a special nickel sulfide treatment furnace and a special nickel sulfide elimination process to homogenize the glass pieces. The quality of the nickel sulfide removal process directly affects the important indicator of the glass insulator after operation - the self explosion rate.

 

Glue assembly: Use an assembly machine with steel foot positioning assistance to assemble and glue the insulator insulation parts, steel feet, and steel caps. This step requires attention to ensuring the coaxiality of the steel feet, insulation parts, and steel caps. Poor coaxiality can also lead to high self explosion rates. Inspection: Conduct a 50%

 

Tensile load test: Tensile load test on the glass insulators that have been glued together, check the height of the insulator structure, etc., to ensure that the insulators meet the standard requirements.

 

Finished products package: pack the goods according to customer request.

For overseas customers use export wooden box with fumigation seal.

 

For domestic customer orders use bamboo package
