What Are Pen Needles?

A stylus is a drafting tool commonly used by architects, engineers, or draftsmen to draw fixed-width lines in architectural, engineering, or technical drawings. The stylus uses a refillable ink tube or a removable ink cartridge.

Earlier styluses were used to draw engineering drawings, but now they are also considered

From before to now, both stylus and duckbill pens have been used for industrial purposes. In addition to drawing drawings with pencils, you must also use stylus pens to draw them once. Until recently, comics have flourished, and slowly began to use them to draw comics.

Generally, four thicknesses of 0.1 mm, 0.3 mm, 0.5 mm, and 0.8 mm are selected on the engineering drawing to draw the engineering drawing surface. However, the price of a stylus pen in Taiwan ranges from 200 to 800 yuan, and it is not easy to maintain. In practice, all computer graphics are used. Therefore, the stylus pen is mostly used for students to practice hand-drawing; in the case of limited student budgets In recent years, stylus pens that have been launched for less than a hundred yuan have become a common choice for beginners in graphics or comics.

The correct way of use is to make the pen head perpendicular to the surface of the paper. The lines drawn in this way can show the characteristics of a stylus pen-draw a line of consistent thickness. If you use a thicker stylus ruler such as 0.8 mm for drawing, it is best to use a drawing ruler with a concave edge to prevent ink from contaminating the drawing surface under the ruler.

A stylus tip of 0.1 mm or 0.2 mm or even thinner is very fragile. Be careful not to collide with other objects during use. If the pen tip is bent, the stylus pen is considered scrapped. If you do not use a stylus for more than one or two months, especially a stylus with a fine tip, use warm water to dip the stylus. If you can empty the ink, it is better to ensure that there is no ink in the stylus. After wiping it, it will naturally dry and then collect. It is reserved for next use.

This is because the tip of the stylus is very thin, and if it is not used for a long time, it will be easily blocked by dry ink. If the stylus is unable to produce water, you should first dip it in warm water and then wipe the pen to test whether the ink can flow out. If the ink still does not come out after repeated several times, you can take it to the eyewear shop. Please use a high frequency water washer to clean it. If the pen tip still fails, you can try to disassemble the pen tip for cleaning. However, the needle inside the 0.1 mm stylus pen tip is as thin as a hair, and it is very likely that it cannot be replaced after removal, so it should not be tried easily.

After the use of stylus pens by drawing-related students has been decreasing, repairing stylus pens has become more difficult, as many agents have withdrawn repair stations.
