The PDLC film is in the center. And the film can not fold.
- Put another layer of EVA film on the PDLC film. And check the cleanliness.
- Place another piece of glass. And align with the first glass.
- Recheck all of the material to be clean.
The pdlc smart film shall indent 1mm from each edge of the glass.
The EVA size is the same as glass.
- We recommend high-temperature tape for edge banding.
- Seal the tape around the glass and press the tape. The electrode wires need tapes too.
- Put the laminated glass into the vacuum bag.
- Add gauze to it to draw out air evenly. And drill a hole and seal the edge of the vacuum bag.
- Start to draw out air and check whether the vacuum index is up to standard later.

- Set process parameters. Start the equipment and wait for the equipment processing to be ready.
- It is forbidden to stop during processing. Please contact the technicians if power outage.
- Heat on the furnace for 2 hours.
