Full Answer

Companies generally make plastic pens by the thousands, as they are the biggest selling market in pens. Each plastic pen has a small metal ball at the tip which, when pressed on to write, rolls and releases ink from the reservoir above it.

  1. Making the ink
  2. First the company has to make the ink in large enough batches to fill all the pens they are making. Heating and cooling the ink helps the chemicals to bond faster.

  3. Stamping and forming the metal components
  4. Making the metal components, such as the metal ball and disc for each pen, is the next step. Each pen has a metal disc and ball that enable the ink to flow as the pen is being used. After the metal is formed, the components are chemically bathed to ensure oils are removed and the metal is clean.

  5. Plastic molding
  6. Next the plastic housing components for the pen are created. This is the plastic piece that a writer grips and it holds the ink and ball.

  7. Filling the pen
  8. The penultimate step is filling the pen with the ink and placing all the components inside the plastic housing. The pieces are put together, then put under an injector which fills the ink reservoir with ink.

  9. Packaging and shipping
  10. The last step is packaging the pens in sets, plastic packaging and then shipping the pens to various vendors.
