A Brief Introduction to Gel Pens

Gel pen, abbreviated as gel ink ballpoint pen, originated in Japan, is a novel writing tool popular in the world. According to the type of pen, ink color, structure and so on can be divided into different types of neutral pens, you can choose according to your own needs.

Gel pen has the advantages of both fountain pen and oil ballpoint pen. It is comfortable to write, low ink viscosity and easy to lubricate. The viscosity of writing medium is between water and oil, so it is smoother than ordinary oil ballpoint pen. It is an upgrading product of oil ballpoint pen. The size of the neutral pen tip can be roughly divided into 1.0mm and 0.5mm.

Pen type

Bullet head type

Looking closely at the pens of these neutral pens, we can see that they are like bullets. In the manufacturing process, we cut a rod into a complete pen through metal cutting. Bullet head type is suitable for making thicker pen, the market is more 0.5MM, the thickest can reach 1.2.

Needle tube type

Usually, we call this type of pen “full needle tube”. The key difference between the bullet pen and the bullet pen is that the bullet pen differs from the bullet pen.

Cutting method is processed. Before being processed into a pen head, it is a complete thin tube, which makes three concave points at the front end of the thin tube from three directions by precision instruments, forming a bowl seat for ball balls, while the back thin tube forms a triangular oil groove. Ink flows out through the oil tank, and then through the ball rolling out of the ink, complete the writing process. Needle and tube type is suitable for making thinner pens, such as 0.30, 0.25 and so on.

Half needle tube

The semi-needle tube is between the bullet head and the needle tube, and its shape is more beautiful. The tip of a pen can be as thin as a needle tube, while the end of a pen is as big as the end of a bullet. Semi-needle tube can make relatively fine pens, such as 0.48, 0.35 and so on.

What is the oily substance at the tail of the neutral pen core?

The oily substance at the tail of the neutral pen core is called lithium ester of the neutral pen tail oil. Its functions are as follows:

  1. Keep good moisturizing seal to prevent ink evaporation or backflow overflow.
  2. When writing with neutral pen, lithium ester can follow up like a piston at any time, press the ink down by atmospheric pressure, and keep the neutral pen writing smoothly until the ink is finished.
