Can t China make pen balls? Can ballpoint pen ball balls be produced in China

The first choice is to tell everyone directly: China can make high-quality pen ball beads!

So why is there such an argument that "China can't make pen balls"? Actually, it can probably be understood like this:

1. Under the guise of being released for some marketing purpose;

2. Works written by authors who do not know the truth;

So why doesn't China make pen balls? Here's the thing:

1. The technical content of the production of pen balls is relatively high, and the energy consumption is large;

2. There are high-quality and affordable pen ball imports from abroad;

After weighing the pros and cons, China's choice to import pen ball beads is the result of market regulation, so it is not like many people say: China can't make pen ball balls!

So what kind of pen ball beads can China make?

In fact, Zhongwei can not only make high-quality steel pen balls, but also use new engineering plastics to manufacture high-end pen balls made of ultra-high-performance plastic materials, which have better use effects and longer life.

Balls are not easy to produce.

Now it's more reliable, and this one is more reliable.

Don't look at a small ball bead, it has to go through a 20-degree process.

It's 2019, and I'm carrying a paragraph from the headlines.

This thing, the domestic market with a total output value of only 100 million yuan, and a few companies in Switzerland and Japan are eating in the world, and the United States does not make this thing.

As a result, a domestic seller of anxiety desperately came out.

Now some companies in Japan and Switzerland have gone out of business. ”

Ballpoint pen balls can already be produced in China.

The Chinese version of ballpoint pen balls is made by TISCO Group in China.

Successfully developed, after 5 years of hard work, in September 2016, TISCO Group finally developed the "additive Zhiwei ridge" evenly distributed nib steel, this batch of stainless steel balls with a diameter of millimeters, and finally proudly wrote "Made in China."

of the logo. The ballpoint pen nib is divided into the ball bead and the ball seat body on the nib, the key part of the pen tip is the ball ball, its mountain letter size accuracy is in two microns, surface roughness.

requirements in microns; At the very top of the nib, the thickness is only millimeters. Extremely high machining accuracy, stainless steel raw materials put forward extremely high performance requirements, not only easy to cut, processing can not crack when penetrating, it can be said that the small "nib" is a great test of Made in China, Made in China to achieve a great breakthrough in ballpoint pen balls, it is not easy.

*No**, China has been able to produce ballballs for ballpoint pens.

The ballpoint pen balls of the Chinese Sanpai Kai version were successfully developed by China's TISCO Group. After 5 years of hard work, in September 2016, TISCO Group finally smiled at the development of "additives" evenly distributed nib steel, this batch of millimeter diameter of the call stainless steel balls finally proudly written on the "Made in China" logo.

The state supports and encourages scientific and technological innovation, and patent examiners, on the contrary, do everything possible to set up obstacles to affect patent approval.

Numerous examiners have always fabricated facts: Compare Document 1 (US 2018 0199243

a1) the unachievable outer diameter of the spring is equal to the specific embodiment.

Why do the examiners always go against scientific common sense, insist on wrong reasons, and what is their motive for not changing until now?

After the patent application No. 2016103139119 went through the substantive examination, reexamination, and litigation, the examiner also mistakenly and deliberately fabricated the so-called specific embodiments that did not exist in the comparison document 1. Because, assuming that the outer diameter of the densely wound spring 23 is equal to 0 25mm, and the inner diameter of the densely wound spring wound by the jack wire diameter 0 1mm is only 0 05mm, it can be seen that the dense wound spring pores that are already smaller than the diameter of the hair cannot ensure that the neutral ink with higher thixotropic viscosity flows smoothly in the densely wound spring hole, so that the ink flow rate of the pen head of this special large-diameter ball ball ball becomes less, and the stitches become faint and broken when the pen is written, and the opposite teaching that the invention cannot be realized is directly given.

A Comparison of the attached drawing 3 of document 1 clearly shows that the diameter of the shrinkage in the deep hole of the step at the rear of the ball seat of the ordinary spring pen nib has a jackswire structure with a reserved length greater than the radius of the ball, that is, the length of the jackswire is greater than the radius of the ball.

B The accompanying drawing 1 of the patent application clearly shows that the technical features limited by claim 1: the gap uniform spring end close to the protruding seat in the smooth pipe hole has an extremely shortened jackswire stable anti-polarization structure, that is, the length of the jacking wire is less than the radius of the ball.

It can be seen that the comparison document 1 does not disclose the technical scheme of the extremely shortened (ultra-short) jacking wire stable anti-polarization structure (i.e., the length of the jacking wire of the present application is less than the radius of the ball seat); Comparison document 1 can not solve the same technical problem as the needle tube spring nib of the present application, "to prevent the tip end of the top wire from squeezing between the ball and the gap between the ball and the ball seat"; Comparison document 1 cannot achieve the same technical effect as the present application: "simple structure, reliable performance, convenient for pen nib matching and assembly, short and accurate positioning of the top wire in the tube hole, smooth ball rotation and ink circulation".

In addition, as described in the background technology of Chenguang Stationery's invention patent, the needle tube spring nib belongs to the key needs of scientific and technological innovation product upgrading in this field. The technology of the present invention is mature, practical and reliable, and many ballpoint pen manufacturers hope to adopt after confirming the right, improve the scientific and technological level of China's ballpoint pen manufacturing country to become a creative power.

We have always relied on imports for ballpoint pen refills, but many people misunderstand that we cannot produce them independently, what is the truth behind it?

China does not yet have the capacity to produce die steel, including 'balls' on ballpoint nibs, which still need to be imported. This requires restructuring adjustments.

How did the ballpoint pen come about?

A long, long time ago, Orientals used brushes and inkstones, and Westerners used various dipping pens, both of which were not suitable for travel. Later, absorbent fountain pens appeared, but these writing instruments were prone to leakage, climate and the need to be refilled with ink, which made it particularly inconvenient for journalists who were often on the go.

At the end of the 19th century, the rudiments of ballpoint pens appeared in Europe. On October 30, 1888, an American journalist named John Loud obtained the first patent for a ballpoint pen, which he named ballpoint pen, but did not commercialize. Later, similar designs appeared in the United Kingdom and Germany, but they did not attract widespread attention due to their poor performance.

It wasn't until June 1943 that another journalist, László Bíró of Hungary, applied for a European patent for his invention of the Biro ballpoint pen. Instead of traditional inks, he used fast-drying inks similar to newspaper inks, and to avoid clogging of viscous ink, Bíró installed small rotating metal balls at the top of the ink tubes that served as caps to prevent the ink from drying out and to control the rate at which the ink flowed out.

Later, the British ** purchased the patent to use the BIRO ballpoint pen and equipped it with the Royal Air Force. Pilots say goodbye to pens and never have to worry about getting covered in ink after flying at high altitudes at low pressure. During World War II, the Biro ballpoint pen was widely used in the military due to its sturdiness and ability to adapt to the battlefield environment.

Ballpoint nib.

There are strict adaptation requirements between the right groove positions, and the processing error requirements cannot exceed millimeters.

It is a misunderstanding to say that China can not produce ballpoint pen nibs, China has developed pen nib processing equipment on the basis of imitation decades ago, and has also produced its own ballpoint pen nibs, but the accuracy and production efficiency can not be compared with foreign technology.

In recent years, China's pen-making industry has made great progress, with an annual output of nearly 40 billion pens, accounting for 80% of the world's total. Due to the poor technical level of pen nib production, 10 billion pen nibs are imported every year, which is the origin of the so-called "cannot produce pen nibs".

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

January 2017, toobai

The original iron and steel group has come out with good news, and has made the "nib steel dao" for ballpoint pen nibs in batches, and the future domestic ballpoint nibs are expected to completely replace imports. Right.

The dimensional accuracy of the key parts of the nib, the surface roughness is required to be microns, and the thickness is only to millimeters at the very top of the nib.

Haven't you ever used a domestic ballpoint pen?

It can definitely be made, but it is not made.

Do something, don't do something.

The gap in the steel of the Chinese ballpoint pen has been filled by Taiyuan Iron and Steel in recent days, and this "localization" has made the Chinese industry raise its eyebrows. At the same time, another component of the nib, the ball beads, has also aroused the attention of readers: whether the ball beads have been localized?

What is the current profit situation?After the investigation, it was found that the ball bead industry is currently in a relatively embarrassing situation.

The head of a tungsten carbide ball bead manufacturer in Shanghai said in an interview, "A pen can't sell much money, and the profit of ball beads as an accessory is very low." Although the quantity sounds huge, the output value is not high, and the profit of a single ball is calculated in millimeters. ”

The ballpoint pen nib is divided into a ball body and a ball on the nib. The ball body is referred to by the outside world as the nib steel, because it puts forward extremely high performance requirements for stainless steel raw materials, which must be easy to cut, and can not be cracked during processing, before the production of nib steel, whether it is equipment or raw materials, has long been in the hands of Switzerland, Japan and other countries. In contrast, China has long been able to produce its own balls and make them available for export.

The "ballpoint pen" is more difficult to build than an aircraft carrier?Only 3 countries can build it, and China is one of them.

Yes, TISCO has already made it.

The problem is that this market is too small, the national demand for ballpoint pen steel balls is less than 1,000 tons a year, even if you occupy 50% of the market share, the output value does not exceed 50 million yuan.

For 1,000 tons of steel, you have to reopen a production line, and the production will meet the requirements in 1-2 weeks, and the rest of the time will have to overhaul and maintain the production line, which is too cost-effective.

The main reason is that the balls of ballpoint pens require technology, so they are difficult to manufacture.

This thing is in great need of technology, and their technology has not reached this level, and it has come out quickly.

Because China is still not very mature in this area, it still needs to be learned.

Because this ball is very high-tech inside, it needs a certain amount of research.
