Manufacturing process of pen and advantage and disadvantage
Answers
A variety of raw materials are used for making the components of a ballpoint pen, including metals, plastics, and other chemicals. When ballpoint pens were first developed, an ordinary steel ball was used. That ball has since been replaced by a textured tungsten carbide ball. This material is superior because it is particularly resistant to deforming. The ball is designed to be a perfect sphere that can literally grip most any writing surface. Its surface is actually composed of over 50,000 polished surfaces and pits. The pits are connected by a series of channels that are continuous throughout the entire sphere. This design allows the ink to be present on both the surface and interior of the ball.
The points of most ballpoint pens are made out of brass, which is an alloy of copper and zinc. This material is used because of its strength, resistance to corrosion, appealing appearance, and ability to be easily formed. Other parts, like the ink cartridge, the body, or the spring can also be made with brass. Aluminum is also used in some cases to make the pen body, and stainless steel can be used to make pen components. Precious metals such as gold, silver, or platinum are plated onto more expensive pens.
Advantages
1. Ball pens dry faster aa compared to ink pens.
2. If you write using ball pen then it will be as it is of water is spilled over it but if it is written using ink pen then the ink will be spilled.
3. There is no hassle of filling ink in hall pens as you get refills for the same.
4. No need to carry extra cartridge or ink pot for your ink pens as you will have ball pens and extra refills for them with you.
disadvantages
One of the main disadvantages is that you cannot erase a pen. Once you've written something in pen it stays there. Another one is if you press to hard the ink could go through the page onto the table or whatever you're writing on. Also, a pen can run out of ink. Unlike a pencil you can't sharpen a pen.
