We were at the National Mail Centre where all the mail in Malaysia gets sorted out before distribution. The visit was made possible because a 7yo inquisitive mind asked her mom what happens when she posts a letter.
Spiral conveyor belt
The centre has been in operation for just a year. It covers 4 acres and has state of the art equipment
The kids were allowed to stamp a stack of letters.
More letters to be sorted. Letters that were of standard size and had the address written in the correct order was easy - just put through a machine that scans the letter and off it goes....
As we were leaving, sacks of mail were delivered. We didn't get to see many of the machines in operation and were told that a better visit would be at 2pm. A night visit is possible as well.
