Report

 

Technical Visit to Longhui Glass Factory

 

A technical visit to Longhui Glass Factory was organized on 6 October 2018. The Director – Mr. Andrew Chiu of Longhui Glass warmly received our delegation. The representative introduced their factory, in that Longhui was established in 1994, and the group has 4 glass manufacturing factories. The Dongguan Factory mainly focuses on the Hong Kong Market. Glass from production is supplied to private developers and public housing projects. The three factories in Huizhou focus on Mainland markets. They have acquired certification in terms of quality, environmental and national standards. The Longhui factory has more than 60 machines for conducting the different processes of glass production. The maximum size of glass which can be produced is about 2.9m x 6.0m.

 

The production workflow of cutting, grinding, washing, tempering, IGU, lamination, silk screen and heat soaking was also introduced. The factory has adopted a first-in-first-out approach to managing stock levels, and all raw materials are traceable, including glass, sealant, polyvinyl butyral (PVB) and paint.

 

A dust free room has also been installed separately for lamination, silk screen and IGU production. A laboratory was also available for product quality control. Low-e glass products are also produced.

 

After the talk, we were taken to visit their workshops. We were introduced to the process of glass manufacturing; the cutting and edge grinding workshop, drill-hole workshop, tempered glass workshop, jet convection combined flat tempering furnace. A sample of tempered glass was made to show us the acceptable level of less than 42 granular holes within 50 x 50mm square area measurement of broken glass. We then visited the silk screen glass workshop and the dust free room for laminated glass manufacturing. In the IGU room, which is temperature controlled and less than 65% humidity, the polyvinyl butyral interlayer was placed in the glass frame and then transferred to a vertical panel machine for assembly. Desiccant is injected into the frame holes and used as an adsorbent to de-hydrate any water between the two assembly panes. We then visited two heat soak test Furnaces. The visit ended with a question-and-answer session.
