The main steps involved with making pens include stamping and forming the metal components inside the pen, molding the plastic housing and filling the pens. Some companies make the ink, as well.
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.

- Filling the pen
- Packaging and shipping
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.
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.
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.
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.
The last step is packaging the pens in sets, plastic packaging and then shipping the pens to various vendors.
