Pyrex Glass Shade for G9

We mainly produce according to your individual requests.

The advantages of borosilicate glass consist in its multifunctionalism. Borosilicate glass combines high heat resistance with high stability against chemical aggressions. The long-term service temperature is around 450°C. Furthermore, the glass is resistant to water, neutral and acid solutions, strong acids and saline solutions as well as to chlorine, bromine, iodine and organic substances. These characteristics allow the application where soda-lime glass fails.Owing to its high optical translucency, borosilicate glass already transmits part of UV-B radiation and UV-A radiation very much.
Yao glass supply wide range of borosilicate and quartz glass tube. With special technic of heat moulding,precision machines provide the pipes to obtain bordering, flanges, amendments of diameter, hollowing, with very restricted tolerances.Colored borosilicate glass tubes are also available.



Our Capabilities

Edge treatment
For the production of thermally toughened safety glass, the minimum requirement of edge finishing is an arrissed edge. In many cases, however, we recommend a ground edge due to stability reasons. The edge finishing is made on round and form grinding machines, double edgers as well as on CNC-working units. Our standard edge finishing is the C-edge (= pencil edge). On request, we can also produce other edge forms such as straight edge with arriss, bevelled edge and facets.On basis of ground edge,we make farther machining to provide polished edge, which is the best finish of edge.In this way, you can see throught from the side of glass.

Grinded edge
Cut chamfered edge
Surface finish
clear
sandblasted
Silk-screen printing

Holes
The holes in the glass are produced with tolerances different from those known of metal working due to the characteristics of the material glass. Glass is first slightly drilled from the bottom and then drilled through the complete glass from the top with a hollow diamond drill. Holes are generally available in diameters of 4 to 240 mm. Bigger hole diameters and inner edge treatment such as polishing are possible on request.

Printing
We make decoration of the glass surface by silk screen printing with ceramic colours. The colour is first applied to the glass surface, dried up and finally, during the process of thermal toughening, it melts with the glass so that a decoration which is resistant to scratches is produced. Apart from ceramic colours, organic glass colours may be used.

Sandblasting
Corundum is blown on the glass surface with a fan. The sandblasting can be made completely or partially onto the glass surface.

Special requests
Apart from these standard treatments, please inform us about your requirements. We will be pleased to find a solution for your ideas.

Packing
As our standard, we pack in between glasses with white paper. We can deliver you reusable or non-reusable transport packaging which is subject to agreement. Furthermore, individual packing solutions are possible.
