When you refurbish iPhone screens, you may all familiar with how to use a heating plate and alloy wire to separate the broken glass, if you are good at this step, you may still to use the same way to separate the curved screens, just take care to use very thin wire. But we have another better way to do it, it uses the Frozen Separator Machine, it is an easier and safer way.
Usually, if you just separate the glass for curved screen, just request the frozen separator machine can reach -145℃ ~ -150℃ is ok, Frozen Separator Machine is a big size and heavy package, so just select a middle one is ok, can save much shipping cost for you, but also can works.

This Frozen Separator Machine can display the current temperature, time countdown and room temperature on the touchscreen, when the current temperature reaches -175℃, you can put the screens in, and close the door, set the time countdown at 90 seconds, then start it.
The glue and the screen naturally fall off under -175℃, it doesn't damage the LCD and polarizer, when the time is over, the machine will automatically whistle, then you can open the door to take out the screen, then you can easily open the screen glass with a plastic card.
Note: test the LCD after ice crystals disappear
Warm tips: if you just want to separate the glass and keep the frame on LCD, then set the Frozen Separator Machine temperature at -150℃, because the glass first fall off under this temperature, when the temperature is around -175℃, then the frame will fall off too.
After separate the glass, you need to clean the glue on LCD, the glue remover may help you a lot. This glue remover special design for the LCD glue removing, no need to change the needle, can work for half an hour.

After cleaning the glue on LCD, you need to put the OCA on new glass, the special mold will help you in this step.
If you don't remove the frame for the curved screen, then suggest you use 200um or 250um OCA.
But if you already removed the frame, then it is better to use the thinner OCA, maybe 100um or 125um OCA.
