How Does a Ballpoint Pen Work?

Parts That Make the Ballpoint Pen Work: We use ballpoint pens in our day-to-day life. They are used at school, home and the office. Most of us know ballpoint pens don't write very well when the writing tip is higher than its opposite end. That is because it is primarily a gravity-reliant writing instrument. The ballpoint pen has four basic parts that enable it to work; the writing tip, socket, ink reservoir and the connecting tube

• Inner Workings: There is a reason for this style of pen to have the name "ballpoint". Its writing tip is actually a tiny ball that is fitted into a socket, allowing it to roll around freely. The small ball can be made of a steel, tungsten carbide or brass. A narrow tube, called the ink reservoir, holds the ink, and a connecting tube connects the ink reservoir to the socket and ball. When we hold a ballpoint pen in our hand and begin to write, the ball rolls around in the socket, moving ink from inside the pen to the writing paper. Because of its design, the ink used in this type of pen tends to be thicker and sticky. A thinner ink would have a tendency to leak out from where the ball and socket fit together
• Basic Ballpoint Pens: The ballpoint pen has an outer cover that surrounds the ink reservoir. This is the part of the pen that we hold in our hand as we write. Some covers resemble a thick, plastic, straw-like object. Other covers are designed to fit the contours of our hand, and some are embellished with rubber-like grips. The writing tip of a basic ballpoint pen sticks out of one end of the pen's cover. On the opposite end, a small button-like cap is inserted into the end of the pen. Removable caps to cover the writing tips are often included to prevent the ink from drying out
• Mechanized Ballpoint Pens: Some ballpoint pen designs are more elaborate, and instead of the removable cap, they have a clicking mechanism. The mechanism moves the writing tip in and out of the cover when the user pushes the button that is located on the opposite end of the pen. This push button replaces the small cap found on the ends of non-mechanized ballpoint pens
• Gravity and Ink: Some ballpoint pens are not completely dependent on gravity to work. In those, designs there is a constant pressure applied behind the column of ink, enabling the writer to use the pen even if the writing tip is elevated. Typically the ballpoint pen requires a certain amount of pressure to be applied in order for it to work. It lacks the free-flowing quality found in some other pen designs

How to Repair a Ball Point Pen Cartridge?

The ink cartridge in a ball point pen can cause a number of problems. The most popular assumption is that the cartridge has run out of ink, but there can be other reasons. The ball itself may be stuck in the tip, there could be air in the cartridge or it may be dry. Any of these can occur if you have not used the pen in a while. You can try a number of things to repair the cartridge before you ultimately must replace it

• Unscrew the upper or lower portion of the pen -- it can vary depending on the exact type -- and remove the cartridge. Don't lose any of the springs or other components that may fall out and remember where each one goes
• Inspect the cartridge to see if it still contains ink and reassemble the pen if this is so. These first two steps are only needed if this pen has an opaque shell with a clear cartridge
• Tap the pen's tip on a hard glass surface and then run the tip over the surface multiple times quickly to try to free up a stuck ballpoint
• Heat the tip of the pen with a cigarette lighter for a couple of seconds to melt any ink that may have dried within the tip
• Suck on the pen's tip with your mouth to try and remove any air pockets that may have built up. Be careful of any ink that may come into your mouth; spit it out and wash out your mouth immediately if this happens
• Apply a small amount of window cleaner to your finger while wearing a rubber glove and then rub the cleaning solution into the tip of the pen to try and moisten the tip
• Install a new cartridge in the pen if you have determined the current cartridge is completely empty and/or dry. The exact type of cartridge you need can vary on your particular pen

How Are Ballpoint Pens Made:

Overview of Ballpoint Pens:

• A ballpoint pen is a writing instrument that dispenses ink via a metallic sphere at the pen's tip. There are two main types of ballpoint pens: disposable and refillable. Disposable pens contain a fixed plastic ink cartridge and are discarded when the ink is used up. Refillable pens have a removable ink cartridge that can be replaced when empty. Disposable pens are made from plastic while refillable pens are made from either metal or plastic. Some ballpoint pens have a retractable tip that is attached to a spring, which can be retracted or deployed by a button at the top of the pen. Ballpoint pens are cheap and durable and are the writing instrument of choice in modern society

Components of Ballpoint Pens:

• A variety of components are used to make ballpoint pens, including plastic, metal and chemicals. In most ballpoint pens, the writing sphere is made from brass, although you can also use steel or tungsten. In metal pens, the body, ink cartridge and spring are also made of brass or aluminum. Virtually all ballpoint pens contain a significant amount of plastic. Even the most expensive pens use plastic for the push button, ink cartridge, cap and tip. Ballpoint pen manufacturers use a variety of plastics, including high-density polyethylene, vinyl resins and thermosetting plastic, which remains rigid after being molded and cooled

Manufacturing Process -- Ink:

• Ink is manufactured by combining a variety of chemicals, which are then mixed together and heated or cooled in order to facilitate the necessary chemical combinations. Workers follow strict formulas when producing ink, and most modern pen manufacturers use computerized controls to regulate the quantities of chemicals and the mixing process. A separate group of workers performs quality checks throughout the ink manufacturing process

Manufacturing Process -- Metal:

• The metallic writing spheres for ballpoint pens are generally purchased from an outside supplier, such as a light metal manufacturing business. Pen manufacturers create the remaining components for metal pens using metal stamping and molding equipment. Small pieces of metal are fed into a molding machine, which liquefies the metal and pours it into a compression chamber. The compression chamber injects the liquefied metal into a die cast mold, which cools the metal and forms the various pen pieces. When the metal is cooled and hardened, any excess metal is scrapped of. The die cast opens and the pen component is removed. The components are then cleaned and machine-cut according to the specifications of the pen for which they will be used. The cut pieces are machine polished and cleaned again before being sent to assembly

Manufacturing Process -- Plastic:

• The plastic components are manufactured by injection molding. In this process, plastic resin is placed in a hopper, which forces the resin through a heated compartment. The heat liquefies the resin, which is injected into a die cast mold, cooled and removed. Excess plastic is then scrapped away, and the pieces are polished, cleaned and sent to assembly

Assembly:

• During the assembly process, the metallic writing sphere is first inserted into a cavity at the tip of the ink cartridge. The ink cartridge is then placed in an injector, which fills the cartridge with ink. For retractable pens, workers then attach a spring to the front of the cartridge to allow the tip to retract and deploy. The completed ink cartridge is then placed inside the body of the pen. Then the pen's cap and top are attached. Assembly is now complete, and the finished pens are cleaned, packaged and shipped
