The most common and most useful thing in our life is the ballpoint pen, which is not only used by students, but also often used by adults in office work. Even in today’s era when laptops are very popular, it still cannot replace the ballpoint pen in people’s lives. Important position, but it is such a small ballpoint pen, the production industry is not easy. Recently, “China can’t make small ballpoint pen balls” has become a hot topic among netizens.
With an annual output of more than 40 billion ballpoint pens, China is already a well-deserved major pen-making country, but a large number of “balls” at the tip of ballpoint pens need to be imported. The production of the ball seat on the nib, whether it is equipment or raw materials, has long been in the hands of countries such as Switzerland and Japan.
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 writing principle of the ballpoint pen.
The principle of ballpoint pen writing
The writing principle of the ballpoint pen is actually mainly using the friction between the ball and the paper. The tip of the pen is a small steel ball, which is embedded in a small cylindrical copper bowl, and then connected to a plastic tube filled with ink. When using a ballpoint pen, the contact between the ball and the paper surface generates friction, making the ball roll in the ball seat, and the ink flows down from the surroundings with the rotation of the ball, so that the ink in the pen core is brought out, and the purpose of writing can be realized .
ballpoint pen production process
The production process of the ballpoint pen is mainly divided into four parts, making plastic molding molds, processing various parts by injection molding machines, assembling various parts, and packaging.
plastic molding 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 ballpoint pen shape, pen cap, pen cap and other parts. The plastic mold is 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 is a molded cavity in this combination.
Injection molding machine processing each part
After the mold is made, the various parts required for the ballpoint pen can be made. By clamping the mold on the injection molding machine, injecting the melted plastic liquid into it, and waiting for it to cool down, the various parts can be obtained.
Assemble the parts
The molding of each part is completed by the injection molding machine, and then the finished 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. It is carried out by using test tube production line equipment. The assembly of ballpoint pen parts can guarantee the quality of the final product of the ballpoint pen.
Package
After the ballpoint pen is assembled, it comes to the packaging stage. The workers in the workshop will complete the packaging of the ballpoint pen according to the pre-designed specifications and styles, and finally the packaged ballpoint pen can be sent to the warehouse. In this way, the production of a ballpoint pen is completed.
The production of a good ballpoint pen is closely related to every step in the production process. The test tube production line equipment is a very good equipment in the assembly process, so don’t ignore it.
