| 1. When the well-assembled glass with EVA is loaded, vacuum is started for about 15 minutes at room temperature.
2. Then it is increased from room temperature until the glass surface reaches 110 oC. It is then kept at this temperature for about 10-30 minutes, depending on glass thickness.
3. Then reduce temperature remaining vacuum on.
4. When glass surface is cooled down to 60 oC, turn off the vacuum. If decorative design substrate material is used, it is recommended to be cooled down to 40 oC.
5. The vacuum is then turned off and the glass can be unloaded.
Remarks
This process instruction shown above is only for reference. The procedure and data are vary depending on,
1. the design and structure of the oven.
2. glass thickness
3. the characteristic of the decorative substrate
material.
Therefore, trial and test is required to obtain
the most optimum procedure and data.
The temperature mentioned above always refers
to glass surface temperature. |
