1. Pencils are made of a kind of wood called incense cedar, which are flexible enough to shape but sturdy enough to withstand pressure under a person’s hands. The cedars are cut into the usual 5mm-thick slats (18 by 7cm) before they are took to the pencil factories.
  2. The slats placed in machines and cut several grooves into the middle of them. These grooves designed to hold the lead of the pencil.
  3. The grooves will be filled with glue which will serve as a type of padding to prevent the lead from breaking inside the pencil.
  4. After passing under the glue applicator, the slats will pass under a lead-laying wheel. The wheel, where the lead are attached and evenly spaced on its surface, will roll over the slats, filling the lead into the grooves. It’s basically the same process for every pencil there is— the only difference is the components of the lead inside (e.g. the lead of colored lead pencils are made of coloring materials, such as dyes and pigments instead of graphite and requires no baking).
  5. Another group of slats will be flipped over the slats with lead to cover them. These slats will end up in a kind of sandwich pile that will be compressed by another machine to make the glue dry fast.
  6. Finally, the slats will pass into two types of cutting machine, which will separate the slats into pencils. The pencil will now be ready for QC quality checking.
  7. A factory worker will pick a pencil from the pile, sharpen it, put it (sharpened end up) under a machine that will apply pressure to it. Normally, a pencil requested to hold at least 2 kg of force in order to pass the quality test.
  8. The pencils will now be coated with several layers of lacquer until stamped with the company’s logo. The pencil will then be placed into another machine to cap or to add rubber at another end of the pencil.
