How Are Pencils Made?

1. The wood is softened and then cut into slats that are called  pencil stock's.

2. A wax and stain are applied  and the slats are passed under a cutting wheel.

3. The grooves in the slats are filled with a special with elastic glue for the lead.

4. Now its  time to add the lead. Lead is created by mixing graphite and clay and baking  it in a oven at  about 1500 degrees. It is turned into lead  which is conman  terminology used to describe the inside of a pencil.

5. After the pencil is loaded with lead its time for slat of wood to be on the top this is done on a conveyor belt with an  automatic arm  that flips the glue over the stacks on top of the other slats conating  the lead.

6. A mechanised plunger squeezes the sandwich  together  with over 2,000 pounds pressure. The wood slats are compress  as the glue  has to time dry.

7. After about an hour the sandwich is are sliced into pencils a fast spinning cutter is used to shape the pencils into a hexagon design from there the pencils are a sperate from the sandwich into individual pieces. Any  pencil with defects are discard.

8. One at a time the pencils go thorough  a  lacquering head giving them a colour  and sheen.
The surface is coated 4-10 times of paint depending on  the desired quality and colour.

9. The final step is  adding a rubber at the very top of the pencil with a assembly machine. First the machine squeezes the top of the pencil  and it slides on the alumnil part.

10. Some pencil are wrapped in decorated film  with intricate designs  while others are screen printed in foil stamps.
