Can China make ballpoint nibs now? Is ballpoint nibs so difficult to develop?

Recently, "China can't make a small ballpoint pen bead" 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 ballpoint pen nibs need to be imported. The production of the nib ball body, both equipment and raw materials, has long been in the hands of Switzerland, Japan and other countries.

Relevant experts said that every small deviation will affect the fluency and service life of the pen nib, the opening thickness of the nib is less than millimeters, but also take into account the writing angle and pressure, the ball and the nib, the ink groove must be matched "seamlessly", and the processing error can not exceed the millimeter. <>

A ballpoint pen, or ballpoint pen, is a writing instrument that uses dry-thick ink and is brought out and transcribed onto paper by means of a freely rotating steel ball on the tip of the pen. Ballpoint pens have the advantages of simple structure, easy to carry, smooth writing, and suitable for copying, so people from all walks of life from school students to office building clerical staff are happy to use it.

A ballpoint pen is a pen that uses tiny, rotating balls made of brass, steel, or tungsten carbide to release ink onto the paper as you write. The ballpoint pen is very different from its predecessors – reed pens, quill pens, metal nib pens and fountain pens.

The writing principle of the ballpoint pen is mainly to use the ball ball to produce friction in direct contact with the paper surface when writing, so that the ball rolls in the ball seat and brings out the ink or ink in the refill, so as to achieve the purpose of writing.

A ballpoint pen is a pen that uses ink and different pigments to write. 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, and the ink flows down from all sides with the rotation of the steel ball.

The pigment of ballpoint pen ink is a dye. There are three main ink colors: blue, red and black, among which blue ink is the most used. In the past, the pigment components in blue ink were salt-based blue and salt-based blue lotus, and the solvents were oxidized castor oil and ricinoleic acid.

Because salt-based dyes are not lightfast (lightfastness is only grade 1-2), heat-resistant, acid-alkali resistant, so the durability is poor, and it has been eliminated. The "424" blue ballpoint pen and the "322" black ballpoint pen sold on the market have good durability in handwriting.

It is not uncommon to report that scented ballpoint pens are toxic, and the volatile organic compounds contained in inferior scented stationery are toxic and have certain damage to the human body; However, there have been no incidents of poisoning due to the normal use of oil-based ballpoint pens that are not adulterated with volatile organic compounds. <>

In the past, it was all imported. It seems that you can do it yourself now. However, the quality is still not good.

Nonsense, laughing at me. 30 years ago, small rural factories in Yiwu could make ballpoint pen nibs.

I hope that we can make a very good ballpoint pen in China, I don't know what the current situation is. It's still a big problem to build it but it doesn't work very well.

I didn't bother to make these things in Yiwu, and I made a line, and then this line was stopped a year earlier.

China can make ballpoint pen with a small ballball. In the ballpoint pen nib, there are also five grooves to guide the ink and the processing accuracy reaches the order of 1 mm, so it is difficult to develop.

China can now manufacture ballpoint pens, but the quality needs to be improved, the process used in ballpoint pens is relatively fine, so this technology is more difficult to master, so many people now use ballpoint pens are the technology of other countries.

Yes, because the ballpoint pen is small in size and requires extremely high operating skills, it is more difficult, and the surface of the ballpoint pen is smooth and difficult to polish.

The ballpoint pen nib can be made in China.

China can manufacture ballpoint refills and nibs, but the ball-bearing materials on nibs need to be imported. At present, the core of this technology is in the hands of Switzerland, and even the United States, Japan, Germany, and other industrial powers are simply using Swiss equipment.

The nib is divided into a ball on the nib and a ball body. Currently, the diameter. 5~1.

Millimeters of tungsten carbide ball beads can not only meet the needs of domestic production, but also export a large number of them. However, the straight slide form has only a millimeter of ball body, whether it is production equipment or raw materials, has long been in the hands of Switzerland, Japan and other countries. China wants to produce 3.8 billion ballpoint pens every year, and it needs to import more than 1 ton of steel to produce pen nibs with a ton of 120,000 yuan, and pay 150,000 US dollars in foreign exchange.

The key parts of the nib, such as the bowl mouth, have a dimensional accuracy of two microns, and its surface roughness.

The requirements are in. 4 microns. Xu Jundao, manager of the quality department of Ningbo Beifa Group, said.

An integrated production equipment for pen nibs from a Swiss company, it takes more than 20 processes to produce a small ballpoint pen nib. Inside the nib, there are steps of different heights and five grooves to guide the ink, and the machining accuracy is on the order of thousandths of a millimeter.

At the place of the tip of the pen, thickness is only. 3~.4 mm. Extremely high machining accuracy, stainless steel raw materials put forward extremely high performance requirements, not only easy to cut, processing can not crack, small "nib" test made in China.

Ballpoint pens can be produced.

The countries of the pen are Switzerland, Japan, and China.

The nib and ink are the key to the ballpoint pen, where the nib is divided into a ball on the nib and a ball body. Currently, tungsten carbide.

Ball beads are the most widely used at home and abroad, and China has a very good foundation, which can not only meet the needs of domestic production, but also supply a large number of exports. But the production of spheroids, both equipment and raw materials, has long been in the hands of Switzerland, Japan and other countries.

Difficulties in manufacturing ballpoint nibs:

The production of ballpoint pen nibs has high requirements for the precision of processing and the selection of materials. The beads must be very wear-resistant, so the hardness is second only to diamond.

of tungsten carbide as a material.

In the small "ballball" of the ballpoint pen nib, there are also five grooves that guide the ink, and the machining accuracy reaches the order of thousandths of a millimeter.

In order to ensure the fluency and service life of the pen nib, the opening thickness of the nib is less than millimeters, and the processing error of the ball ball and the pen nib and ink groove position can not exceed millimeters.

Ballpoint pen. Small steel balls on the head can be produced in China.

At present, tungsten carbide balls are the most widely used at home and abroad, and China has a good foundation for bright molds, which can not only meet the needs of domestic production, but also export a large number of them. So the small steel balls on the ballpoint pen nib can be produced in China.

However, the production of tungsten carbide ball beads, both equipment and raw materials, has long been in the hands of Switzerland, Japan and other countries. According to reports, foreign production equipment has relatively higher requirements for raw materials, and domestic stainless steel wire rod cannot be applied, so it must rely on free-cutting stainless steel wire rod imported from Japan. At the same time, the ink that matches the shortage also has to be imported from Germany, Japan and other countries.

There are the following reasons:

1. Enterprises blindly imitate, pursue the short-sighted concept of small profits and quick turnover, hold on to the defects, and lack the motivation for independent research and development.

This is a common problem of domestic enterprises, which still pursue the ancient business idea of small profits and quick turnover, over-reliance on imitation, reluctance to research and development, reluctance to invest, and lack of long-term strategy.

2. The core materials and equipment of related industries have long been dependent on imports.

The dependence formed for a long time has caused a dependent industrial structure, which is not available in the early stage of technology and capital, and with the vicious circle, the dependence continues to increase, and in the later stage, it is difficult to return and the difficulty of structural adjustment.

1. The current situation of the problem:

On January 4, 2016, the premier presided over a symposium on resolving excess capacity and achieving relief from difficulties in the steel and coal industry in Taiyuan, Shanxi, and he revealed a "secret": "Last year, we still imported some special categories of high-quality steel in the case of serious overproduction of steel. We do not yet have the capacity to produce mould steel, including 'balls' on ballpoint nibs, which still need to be imported.

This requires restructuring adjustments. ”

More than 3,000 pen-making enterprises, more than 200,000 employees, with an annual output of more than 40 billion ballpoint pens ......China has become a well-deserved pen-making power, but behind a series of proud figures, is the core technology and materials highly dependent on imports, the embarrassing situation of inferior counterfeit products, a large number of ballpoint pen nibs of "pen balls" need to be imported.

2. Summary of the problem:

Chen Sanyuan, honorary vice chairman of the China Pen Association, said that although breakthroughs have been made in free-cutting steel wires, inks and other technologies, enterprises still need a process to accept new technologies and equipment, and we are working hard to increase the promotion of new technologies. However, with advanced technology and equipment, in order to truly manufacture world-class products, it is also necessary to cultivate the "craftsman spirit" of excellence, which is indispensable for China to move from a large pen-making country to a pen-making power.

Popular science: Why has China not been able to make ballpoint pen nibs before? Is it really that hard?
