Quality of Ball Pen

There are several different types, including ballpoint, rollerball, fountain, and felt-tip. Historically, reed pens, quill pens, and dip pens were used. Modern-day pens come in a variety of colors and assortments. The most common contain blue or black ink. I have chosen to analyze three different roller ball pens that dispense a water-based liquid or gel ink through a ball tip similar to that of a ballpoint pen. The less-viscous ink is more-easily absorbed by paper than oil-based ink, and the pen moves more easily across a writing surface. The quality of pen components is checked during all manufacturing stages. Since thousands of parts are made each day, inspecting each one is impossible. Consequently, line inspectors take random samples of pen pieces at certain time intervals and check to ensure that they meet set specifications for size, shape, and consistency. The primary testing method is visual inspection, although more rigorous measurements are also made. Various types of measuring equipment are available. Length measurements are made with a micrometer, or a microscope. Each of these differs in accuracy and application. To test the condition of surface coatings, an optical flat or surface gauge may be used. Like the solid pieces of the pens, quality tests are also performed on the liquid batches of ink. After all the ingredients are added to the batch, a sample is taken to the laboratory for testing. The QC group runs tests such as pH determination, viscosity checks, and appearance evaluations. In addition to these specific tests, line inspectors are also posted at each phase of manufacture. They visually inspect the components as they are made and check for things such as inadequately filled ink reservoirs, deformed pens, and incorrectly assembled parts. Random samples of the final product are also tested to ensure a batch of pens writes correctly. The primary dimensions of product quality include: Performance / Features / Reliability / Conformance /...
