DVD හදන හැටි බලමුද?
Here is tour inside a DVD manufacturing plant in Kazakhstan
The process is fully automatic, the main engineer keeps an eye on it
Optical discs are made of polycarbonate that comes in large bags
Here they are
The granules first get into the drying machine
And then get heated till they become liquid mass
Which gets crammed into a press-form with a stamper inside
Stamper or matrix is a metal plate with precise information. This one is a movie which will be on a DVD in a while
Under the temperature of 250 degrees liquid polycarbonate gets shaped into a disc. And the info on the matrix gets imprinted on it
Workpieces with information get into a cooling machine
Then they get covered with reflecting surface so that laser ray could read the info
Half-finished production
Laser test rejected one copy out of 40
After one lot has been produced it gets painted
Room of temporary storage
Preparing the covers.
These women prepare DVD boxes with an unbelievable speed
Wrapping the boxes with cellophane film
From this distribution center DVDs are delivered to the stores over Kazakhstan
The DVD arrives at the market
