VACUUM TIPS FOR LAMINATING GLASS WITH EVA FILM

Vacuuming is very important for manufacturing laminated glass successfully. If vacuuming is not good, the laminated glass may have bubbles. So there are some tips for vacuuming in the laminating oven.

1-Put some wire net upon the vacuum hole
Sometimes, the silicone upside may seal the vacuum hole and stop the vacuuming, if we put some wire net or fabric upon the vacuum hole, it will avoid the sealing situation.

2-Put some bar around the silicone bag
Sometimes, you can put some bars around the silicone bag to help vacuuming, but note that the height of the bars should be equal to the combination of the laminated glasses you are going to process.

3-Put big glass as template
If you laminate small laminated glasses, you can put a big glass on the silicone bag, then put the small pre-laminated glasses on the big glass, which will help vacuuming and also can avoid the small pre-laminated glass change shapes.
