What the boss has decided, the people below will naturally have to carry it out.

Few people really argue that hard.

The most important thing is that over the years, Cao Yang's decisions have almost always been proven to be correct.

Therefore, although Huan Yongxiang and Dai Hanbiao had some doubts about the independent research and development of tires in their hearts, they did not say much in the end.

Even Huan Yongxiang took the initiative to shift the topic back to bulletproof glass.

"Mr. Cao, in terms of bulletproof glass, Yichuan Guangming Bulletproof Glass Factory in Luozhou came to visit and introduced their bulletproof glass technology."

"However, their bulletproof glass was used more in other occasions before, and it was not used in cars very much."

"If we can also study bulletproof glass like tires, maybe we can consider finding them to OEM when the time comes."

The key technology must be in our own hands.

The Nanshan Group itself has no idea of making glass.

However, bulletproof glass, a relatively special thing, if there is no particularly suitable manufacturer in China who can come up with satisfactory technology, Nanshan Group itself will naturally have to intervene.

After all, it is difficult for high-end car companies not to deal with bulletproof glass.

To a certain extent, bulletproof cars are the fist products of high-end models.

Although the sales are not necessarily particularly good, the impact on the brand is very large.

"Then communicate with them well and see if it is possible to localize bulletproof glass in the future."

Cao Yang is actually not familiar with the bulletproof glass industry, and he has not even had much contact with it in his previous life.

So how to choose a cooperative supplier, he does not intend to interfere.

Anyway, in the end, just come out with a qualified product.

Nanshan Group has a big business, and if you have to do everything, you will be too busy to die.

"Mr. Cao, when it comes to localization, when I communicated with Mr. Xie of Nanshan Special Steel a few days ago, I heard about a thing."

Dai Hanbiao saw that Cao Yang had arranged two difficult parts for himself one after another, and he was also a little worried.

He was worried that he would get more homework back, so he quickly changed the subject.

"Oh? Is there any special situation on the Nanshan Special Steel side? ”

Cao Yang's attention to materials is still relatively high, and now that he sees Dai Hanbiao talking about Nanshan special steel, he naturally wants to pay attention to it.

"Didn't CSR find us to develop high-speed rail bearings before, and now they are developing high-speed rail wheels."

"In fact, for CSR, high-speed rail bearings, wheels and axles are only the three most important parts that cannot be domestically produced, not that these parts are truly 100% localized after they are domestically produced."

"For example, the bolts used on the high-speed railway, which are known as 'never loose', are imported from Dongying, and all domestic fastener manufacturers cannot produce bolts with the same performance."

When Dai Hanbiao said this, Cao Yang was a little impressed.

This matter seems to have been on the hot search in later generations.

"Bolts that never loosen?" Cao Yang further confirmed to see if what Dai Hanbiao said was something he understood.

"Yes, it's especially famous, it's called the 'Hadlock Screw.'"

"Actually, 'hardlock' is a transliteration of the English word 'hard lock,' which means hard lock."

"Dare to give such a name to the screw, but it fully shows the self-confidence of this Dongying company."

"In the advertising slogan, Hardlock Screws brand itself as 'never loose'."

Dai Hanbiao saw that Cao Yang was very interested, so he simply explained what he had learned.

Nanshan Group started as a nut plate in the early days, and the rear wheel bolts are also the fist products of Nanshan Group.

Therefore, Nanshan Group is actually very strong in the fastener industry.

As the person in charge of the parts business, Dai Hanbiao also has a good understanding of the situation of bolts and nuts.

It's even more interesting.

"The Shinkansen of Toei is the stage where Hadlock Nut shows its strength for the first time."

"There are generally 16 carriages on the Shinkansen, and these 16 carriages require a total of 20,000 screws to connect, and as a high-speed train, the average speed of the Shinkansen can reach 250 kilometers per hour, and in the process of high-speed driving, the screws will inevitably loosen."

"Once the screws are loosened, the consequences are unimaginable, and in the most serious cases, it can even directly endanger the lives of passengers. As a result, the Shinkansen has to spend a lot of manpower and material resources every year to tighten these screws. ”

"It's not just a problem for the Shinkansen, it's a common problem for railways around the world."

"If there is a problem, it means that there is an opportunity. Hadlock Industries' General Manager Keyan Lin was keenly aware of the business opportunity and led the team to conduct research and development for 20 years. ”

"Eventually, Hayashi took inspiration from the torii gates of Japanese shrines to create a unique screw that had never been seen before."

Dai Hanbiao's introduction not only attracted Cao Yang's attention.

Huan Yongxiang next to him also listened with relish.

You don't need to use such bolts on the car.

Although engine fastening bolts and other parts also have certain anti-falling requirements, they are certainly not the same level as the requirements of high-speed rail.

"Torii? What does that mean? ”

Without waiting for Cao Yang to ask, Wan Yongxiang first asked questions.

"The torii gate is actually a kind of building that adopts the most common mortise and tenon structure in ancient Chinese architecture, and it is this structure that makes Lin Keyan's mouth open."

"He realized that there was a gap between the nut and the screw, and if he followed the example of an ancient building and drove a wedge into the gap, wouldn't he be able to reinforce the screw?"

"On top of that, Hadlock Industries put all its heart and soul into a small screw."

"In addition to the creativity of the mortise and tenon structure, this company also has its own unique advantage, the company will customize different eccentric quantities for screws of different sizes and materials, and strive for perfection."

"Eventually, their bolts were not only adopted by the Shinkansen, but also by railway companies in many other countries from Hadlock Industries."

"Our high-speed rail is no exception."

"Even if people say that they will give us the drawings, there is no company in Huaxia that can produce bolts of the same quality."

After Dai Hanbiao said this, Cao Yang couldn't help but pout.

This boast is obviously an exaggeration.

"Dongying's manufacturing industry started early, the system is relatively mature, and it has its own industrial chain advantages, so it can better balance price and quality."

"There are so many developed countries in the world that import screws from Dongying, not because these countries can't manufacture the same level of screws themselves, but simply because they are cost-effective."

"If it is said that with this small screw, Dongying can choke the lifeblood of Huaxia high-speed rail, then Dongying may have already controlled the world with this screw."

Obviously, Cao Yang did not agree with some of what Dai Hanbiao said.

Of course, this company's technology is very powerful, and it is a small but sophisticated enterprise, which Cao Yang does not deny.

"Mr. Cao, it sounds like this is true from the point of view, but this type of anti-loosening bolt is really good."

Dai Hanbiao didn't mean to speak to Dongyingren's company, but told the situation he grasped.

"I've heard that there is a company in Hui'an province called Down Threaded Fasteners, and they make a kind of Down bolt that can do a similar job."

"This bolt is a double-turned, equal-sectional, discontinuous thread, which breaks through the concept of ordinary threads."

"The Down's thread is to make a fuss about the bolt, the bolt integrates two different rotation directions of threads, and two different tightening directions of the nut will also be installed during installation, when one nut wants to loosen, it will push the other nut to rotate, and this rotation force will just tighten the other nut."

"Whether it is left-handed or right-handed threads, they are commonly used in the industry, and the Down's thread is only made on a bolt with these two threads, so there are few uncertainties in processing, and it is only necessary to design new processing machinery to be mass-produced."

"The special Down's thread makes the force on each thread segment more even, rather than concentrating too much force like the Hardlock nut, so the Down's thread has less material requirements."

"Although this company has been established for almost ten years, the scale is not large, and this bolt has not yet been applied to high-speed rail."

"Nanshan auto parts can be directly invested and acquired, and then combined with our own fastener production technology, the down's bolts will be produced in large quantities."

"When the time comes, whether it is a southern or northern car, a large number of such bolts will be needed."

Cao Yang's answer made Dai Hanbiao and Huan Yongxiang a little surprised.

Is there really a company in China that can easily get the "bolt that never loosens"?

Dongying company Hardlock has made all its processing drawings public, allowing others to copy them.

This fully illustrates how difficult it is to produce this kind of bolts, and it can be said that they can be proud of themselves in this industry.

Of course, this practice is definitely an insult and contempt for peers.

However, you just can't produce it, or after you produce it, the quality and cost are not as good as others.

In the end, I still can't win against others.

"Mr. Cao, this Tang bolt is really that powerful?"

Dai Hanbiao couldn't help but ask rhetorically.

"It's not amazing, you can go on a business trip tomorrow to take a look."

"But the acquisition should be fast, and when the time comes, you can go to some people from South and North and tell them that we can solve the problem of loosening bolts in a simpler way."

"At the same time, the kind of bolts produced by Hadlock, we also want to produce them, so that everyone knows that we are not technically inadequate, but can use cheaper solutions to achieve the goal."

With Cao Yang's instructions, Dai Hanbiao and others immediately took action.

At this time, the Down's bolt is in the stage where it is just about to erupt, but it has not yet erupted.

This year, their company's product "Tang's threaded fasteners" was recognized as a high-tech product in Hui'an Province.

However, the parts are still basically in small batch production.

Nanshan Group is such a giant that is willing to buy them, and it is naturally not difficult.

Of course, the premise is that the Nanshan Group gives enough money.

Directly let the boss achieve financial freedom.

"Mr. Cao, Mr. Xie, the technology contained in the Hadlock nut is indeed extraordinary, but if you blindly follow such a technical route, it is difficult to create a product with the same performance."

"Let's start by looking at how it works."

"The Hadlock nut consists of a convex nut and a concave nut, and the convex nut is screwed into the bolt first, and then the concave nut is screwed in, and the concave and convex surfaces are mated together."

"Its ingenuity lies in the convex nut, as you can see from the picture, the edge of the convex nut is unevenly thick, forming a structure similar to a door wedge, like a door is stuck by a door wedge, and the concave nut can be firmly locked on the bolt by the convex nut."

"Although this structure is very ingenious, it takes a lot of empirical data to make a good Hadlock nut."

"Because the convex nut is eccentric, that is, the inner circle and the outer circle center on the nut do not coincide, so the machining accuracy is required."

"And the size of the nut is different, the corresponding degree of eccentricity, processing method, and material are also different."

"There is almost no theory to refer to what parameters to use, and it is all based on test data over many years."

"So a lot of companies, including us, have taken the drawings that Hadlock has made public, and they have followed their path, and they have repeatedly failed."

"Since the key to self-locking is the mutual squeezing of the two nuts, a high fatigue strength of the metal is required."

"In this case, the ability of the metal to withstand a regularly varying load over a long period of time without being destroyed."

"Ordinary materials are not up to the task, and the materials used by Hadlock are unique to them, and if they adopt their solution, they will inevitably develop new materials, and the cost will be completely out of control."

Although Tang Zongcai sold the company to Nanshan Group, he still served as the general manager.

It can be said that this week has changed more than he has in a lifetime.

After Nanshan Group completed the acquisition, it immediately called Tang Zongcai and Nie Jian, the chief engineer of CSR, over.

"So you came up with the idea of using an easier way to solve this problem?"

Nie Jian generally understood what Tang Zongcai said.

After all, everyone is an engineering student, although they may not be proficient in bolt and nut technology, but they must have been in contact with it, and even learned some related principles in college.

Although the structure of the Down's bolt is relatively special, the principle is not beyond everyone's understanding.

It can only be said that he chose a very ingenious entry point to make the bolt a presence that does not fall off.

In a way, this is more significant than the difficult anti-falling bolts designed by Hardlock.

"Yes, at present, we can already produce on a small scale, and as long as we add equipment in the future, we can expand production capacity at any time."

"And Nanshan Special Steel has very good rebar, and when the time comes, the performance of our Down's bolts will be more advanced than those tested before."

Tang Zongcai is still very confident in his skills.

Although Hardlock's lockbolts are famous all over the world, it is because their own Down's bolts have not yet been mass-produced.

Otherwise, who wouldn't want to use a cheap and easy-to-use product?

"Mr. Nie, judging from the current situation, the price of an imported Hadlock locking bolt will go to more than ten yuan, which can be described as extremely high."

"Our Down's bolts can achieve the same function, the quality stability is also higher, but the cost can be reduced by half."

"There are so many bolts on a high-speed railway, and with the rapid development of China's high-speed rail industry in the future, the related demand will become greater."

"I think we can start reviewing the issue of domestic substitution as soon as possible."

At this time, Cao Yang also added his opinion on the side.

Good things should be used as soon as possible.

It is even possible to promote Down's bolts overseas, so that more countries' railways can also use this kind of high-quality and inexpensive thing.

The simpler the structure and process of a part, the higher the theoretical quality stability.

Obviously, even a layman, after listening to Tang Zongcai's introduction, knows that Tang's bolts are really much simpler than Hardlock's bolts.

"No problem, this bolt is also the largest imported part besides bearings, wheels and axles."

"It's just that its individual value is not so high, and the technical difficulty was very high before."

"That's why I didn't regard it as the first batch of localized parts to be conquered."

"Now there is a windfall, and we are naturally fully supportive."

"As long as you submit the relevant samples and test reports, I can immediately arrange someone to test load the car."

"When the time comes, we will make Huaxia's high-speed rail a truly 100% localized product."

"This is definitely not a small significance."

Nie Jian's mood was very good.

When Cao Yang called him, he still felt that what Cao Yang said was probably watery.

Now I listened to Tang Zongcai's explanation on the spot and saw the sample again.

His confidence came up at once.

"Mr. Tang, when the time comes, you will contact Mr. Pan of Nanshan Equipment, list the list of production equipment and related technical requirements required by the factory, and let him arrange to connect with you."

"Nanshan Group itself also has bolts and nuts related products and equipment, and when the time comes, we can reorganize it and make the fastener business bigger and stronger."

"Now the fastener company you are responsible for has less than 10 million yuan a year."

"In the future, I hope that the fastener business alone can reach billions a year and become the leading fastener manufacturer in the country and even in the world."

Although Nie Jian, an outsider, was present, Cao Yang did not shy away from it.

directly drew a big pie for Tang Zongcai.

Fasteners can be produced by any manufacturer.

But to do it well, there are few manufacturers.

The locking bolts used in high-speed rail discussed today are just one of the typical representatives.

In fact, there are a lot of bolts and nuts in other fields, which are actually imported.

Some parts may not be noticeable from the appearance.

But if it takes a few years, or more than ten years, the gap is big.

This subdivision alone is worth Tang Zongcai's lifelong research.

"Mr. Cao, don't worry, I will definitely make the group's fastener business bigger and stronger."

"Whether it's high-speed rail bolts, bolts and nuts for passenger cars, or bolts and nuts for commercial vehicles and other machinery and equipment, I hope that as long as customers have needs, our fastener company can respond to them."

Tang Zongcai was very glad that he was able to accept the acquisition, which not only achieved personal financial freedom, but also gave him a greater platform to play.

Nanshan Group's turnover this year is expected to exceed 200 billion yuan, which is definitely a very exaggerated existence.

A fastener company with a turnover of less than 10 million is nothing at all in front of Nanshan Group.

Even in the past few years, the company has entered the fast lane of development, and it looks like it is about to take off.

But who knows if it can really take off?

Besides, it doesn't matter, if you rely on yourself, even if the technology of Down's bolts is very good, you may not be able to get many orders.

For example, today, after hugging my thigh, I immediately met the chief engineer of CSR, and the parts can be installed on the high-speed rail of CSR in the shortest possible time.

This kind of opportunity is just a very simple thing for Nanshan Group.

But for the original Tang Zongcai, there is an insurmountable gap.

"The demand for fasteners in each business unit of our group is a very large number."

"As long as the fastener factory can make all these required fasteners, basically go to the market to win more orders, there will be no big obstacles."

"In particular, the group has its own special steel mill, its own mold factory, and its own equipment factory, and the development of fastener business is still very advantageous compared with other companies."

"Maybe in the future, the fastener company can become a new 10-billion-level enterprise under the group."

As soon as Dai Hanbiao said this, Tang Zongcai looked forward to it even more.

Tens of billions of enterprises!

In the past, there were only a handful of such enterprises in my province, right?

That's a big customer.

Now it is possible for me to become the head of a 10-billion-level enterprise in the future?

Thinking of this, Tang Zongcai was full of energy.

"In addition to loosening bolts on high-speed rail, there are also a lot of other fastener needs."

"Although most of the other parts have been localized, if the products produced by your fastener company are of better quality and cheaper cost, the market can be further expanded on high-speed rail."

At this time, Nie Jian was also willing to sell a favor to Nanshan Group.

Anyway, whoever buys it from is buying, if the enterprises under Nanshan Group can achieve lower cost and better quality, there is no reason why CSR should not use it.

"Then I'll thank you for Mr. Tang."

"Parts such as nut plates and wheel bolts are the parts that Nanshan Group started."

"I believe that after the merger of this business with the original Mr. Tang's company, it can definitely play a role where one plus one is greater than two."

"When the time comes, our Huaxia fasteners will no longer need to be imported from abroad."

When Cao Yang said this, everyone was looking forward to it.

For example, bearings, gears, bolts and nuts are standard parts or quasi-standard parts, and the domestic production capacity is very huge.

But it's really hard to describe the technology.

If we can gradually achieve breakthroughs in these basic parts, the significance behind them is definitely not small.

The road to simplicity!

Only when simple parts can be done well, it is possible to do complex things well.
