The most common and most useful thing in our lives is the ballpoint pen. It is not only used by students, but also used by adults in office work. Even in today’s era when notebook computers are very popular, it still cannot replace the ballpoint pen in people’s lives. Important position, but such a small ballpoint pen, the production industry is not simple. Recently, “China can’t make a small ballpoint pen” has become a hot topic among netizens.
With an annual output of more than 40 billion ballpoint pens, China is already a well-deserved pen-making country, but a large number of “balls” for ballpoint pens need to be imported. The production of the ball seat body on the pen head, whether it is equipment or raw materials, has long been in the hands of Switzerland, Japan and other countries.
Since the production of ballpoint pens is so difficult, today I will talk to you about the production process of ballpoint pens.
First of all, you need to understand the principle of writing with a ballpoint pen.
Ballpoint pen writing principle
The writing principle of the ballpoint pen actually mainly uses the friction between the ball and the paper. The tip of the pen is a small steel ball. The small steel ball is embedded in a small cylindrical copper bowl, and then connected to a plastic tube with ink. When using a ballpoint pen, frictional force is generated through the contact between the ball and the paper surface, so that the ball rolls in the ball seat, and the ink flows down from the surrounding with the rotation of the steel ball, so as to bring out the ink in the pen core, and the purpose of writing can be achieved. .
Ballpoint pen making process
The production process of the ballpoint pen is mainly divided into four parts: making plastic molding molds, processing parts by injection molding machine, assembling parts, and packaging.
Plastic forming mold
The first step in making a ballpoint pen is to make a mold. According to the design parameters of the ballpoint pen, make a mold for the shape of the ballpoint pen, the cap, the cap and other parts. Plastic molds are for the final product to have a complete structure and precise dimensions. The mold is a necessary tool in the production of plastic products. The mold is generally composed of several groups of different parts, and there are formed mold cavities in this combination.
Injection molding machine processing various parts
After the mold is made, you can start to make all the parts required for the ballpoint pen. By clamping the mold on the injection molding machine, and then injecting the melted plastic liquid into it, waiting for it to cool, you can get all the parts.
Assemble the parts
The molding of each part of the parts is completed by the injection molding machine, and then the completed parts need to be sent to the assembly workshop for assembly. This part is very important. It is related to the success or failure of the final ballpoint pen product. The test tube production line equipment is used to carry out The assembly of ballpoint pen parts can ensure the quality of the final product of the ballpoint pen.
Package
After the ball-point pen is assembled, it comes to the packaging process. The workers in the workshop will complete the packaging of the ball-point pen according to the pre-designed specifications and styles. Finally, the well-packaged ball-point pen can be sent to the warehouse. In this way, the production of a ball-point pen is completed.
