Nanshan Industrial Park was put into operation, but Caoyang couldn't be idle.

No, Xiang Changle urged him to submit his paper.

Fortunately, Cao Yang was not unprepared.

So when Xiang Changle urged him, a paper titled "Hot Stamping Forming Technology Will Become the Key to Improving the Strength and Lightweight of the Body Body" appeared in front of everyone.

As a research-oriented person in the automotive industry, although Xiang Changle is not mainly engaged in body design, he has a good understanding of the situation of various parts of the vehicle.

"Xiaocao, I have seen some relevant introductions to this hot stamping technology in journals, but there should not even be a hot stamping line in China now, right?"

"In your paper, you directly said that Nanshan Technology Co., Ltd. has mastered a full set of hot stamping technology, and vigorously promoted the application of this new technology in automobiles, will it offend many people?"

Xiang Changle sees the problem differently from Cao Yang.

At present, the large stamping manufacturers in China are basically subsidiaries of various automobile groups.

Only some parts such as brackets that are not so important have a chance to be given to private enterprises.

For example, Yangcheng Huaqiang Stamping Factory, if it weren't for the fact that the foundation of Yangcheng Automobile Group was too weak and there was no parts subsidiary that could get its hands on, Yangcheng Honda's stamping parts business would definitely not be his turn to do it.

Now Cao Yang advocates a technology that these domestic companies have not mastered to replace the traditional cold stamping technology, which is a smashing of jobs.

When the time comes, Spring City stamping, four-ring stamping, Modu Tonne, and West Wind die punching......

How much do these factories hate Nanshan?

Domestic enterprises have not mastered this technology, if the main engine factory wants to use it, it can only be given to international auto parts companies to do.

Not to mention whether the localization rate will be reduced, the interests of relevant domestic parts manufacturers will definitely be damaged.

"Teacher, this problem is not that serious."

"Not to mention that not all parts of the body are suitable for hot stamping, the direction of each OEM will not be exactly the same."

"According to my survey, Volkswagen, General Motors, Ford and other European and American manufacturers generally tend to use hot stamping technology."

"But those companies in Dongying, they tend to use ultra-high-strength cold stamping technology."

"For example, Yangcheng Apex and Yangcheng Aiji, which Yangcheng Honda is preparing to use, their parent companies already have cold stamping technology that processes 780mpa and 980Mpa, and even have been widely used in the latest models."

"Although there is still a gap compared with the tensile strength of 1500Mpa after hot stamping, not all car companies will choose hot stamping based on comprehensive cost and strength considerations."

"Even if you choose, it is only applicable to a few parts such as A-pillar and B-pillar, and it will not have much impact on domestic stamping manufacturers in a short period of time."

"But if we don't work hard, the market will be monopolized by international giants such as Benteler, Cosma and Gesstop."

Cao Yang knew that in the future, there would be so many parts on the white body of the car, and the competition would be completely fierce.

That is, the profit of hot stamping is still considerable.

At least in the next decade or so, it is a promising industry.

Although Nanshan has no plan to enter the hot stamping parts by itself, Huaqiang factory can do it.

What's more, Nanshan can make a considerable profit from this industry by selling hot stamping presses and hot stamping dies.

For a general mold, a set of one million is considered very expensive.

In later generations, the unit price of most of the stamping dies for auto parts did not exceed 500,000.

And what about the molds for hot-stamped parts?

Before 2010, a set of about 10 million!

Even by 2020, it will be millions.

If you start hot stamping in advance, Nanshan, who has first mastered the production technology of hot stamping die, will be able to eat the fattest piece of cake.

"That's the truth, but people don't like to hear it."

"Your paper is published, if no one pays attention to it, it's better to say."

"If it is spread on a large scale, it will bring a lot of pressure to Nanshan."

"I think it's better to publish it in the school magazine then?"

The thesis of a normal undergraduate student is naturally copied from the east to the west.

At this time, there is no such thing as checking the duplicate or not checking the undergraduate thesis.

It's almost a matter of flickering past.

Anyway, the university pursues strict entry and wide exit, and it is rare that you can not complete your studies.

Undergraduate students who can't graduate because they haven't passed their graduation thesis have never heard of it.

However, Xiang Changle originally wanted to take advantage of Cao Yang's identity and take out their graduation thesis to publicize and publish it.

Now after seeing the content, I am a little hesitant in my heart.

Because this paper is not so much a paper as an advertisement for Nanshan.

The whole article does not introduce too specific technical information, but constantly emphasizes how Nanshan has done in-depth research in hot stamping forming.

He Xiang Changle is embarrassed to promote such a thesis.

"Teacher, hot stamping technology is definitely one of the hot technologies for the manufacture of automobile body stamping parts in the future."

"It's going to be very widely used in the next 20 years, or even the next 30 years."

"I also hope that the associated manufacturers can do a good job in this area of technology accumulation in advance."

"If you have difficulties, you can also come to us Nanshan for cooperation."

"It's actually a good thing for everyone."

Although Tesla began to engage in integrated die-casting in later generations, the number of body components dropped a lot.

But this can cause huge problems after the sale.

So even in 2023, there are not many models in use.

To put it bluntly, the integrated casting technology is to transfer the risk of the cost reduction of the main engine factory to the consumer or insurance company.

It is not a particularly responsible cost-cutting solution.

"You're blowing the cowhide so badly, someone has to believe it when the time comes."

Although Xiang Changle knows Nanshan technology and wants the company to be very powerful, he is also proficient in hot stamping technology, so he is a little skeptical.

"Teacher, don't worry."

"Hot-stamped parts are not functional parts and do not require any durability or functional testing."

"After making it, as long as you ensure that the strength and part accuracy meet the requirements, you can prove that it is qualified."

"We just want to cheat, and we can't help it."

Seeing Cao Yang's confident appearance, Xiang Changle gritted his teeth and was ready to follow this disciple to "mess around".

Soon, he used his connections to submit the article to "Huaxia Automobile Stamping".

This journal is a comprehensive academic journal sponsored by the Automotive Stamping and Forming Technology Branch of the Chinese Society of Automotive Engineers.

It mainly publishes the latest research results, application technologies and development trends in the field of automobile stamping and forming.

Although few people have heard of it, this magazine has a high influence in the domestic automobile stamping industry, and has been widely included in the Chinese Academic Journals Network Publishing Database, the Chinese Journal Full-text Database, and the Chinese Science and Technology Journal Database.

As a result, the paper written by Cao Yang immediately attracted the attention of many people in the industry.

For example, in state-owned enterprises such as Xifeng die punching and Chuncheng stamping, there are some thesis requirements for the technical personnel in them when they hire professional titles.

Even if it's not a must, it's a plus.

In this case, it is natural for everyone to find a way to publish the paper in the journal.

I am also more concerned about the dynamics in the industry.

As a stamping part, in the past, everyone paid the most attention to the mold design.

How to make the parts not crack and wrinkle, these are all related to mold design.

It can be said that the die is the essence of stamping parts.

Liu Darui, as the head of the technical department of Chuncheng Stamping, naturally pays attention to the magazine "Huaxia Automobile Stamping".

Cao Yang's article is so unconventional, and it is not the same subject at all as other people's.

In this case, it is difficult for Liu Darui not to pay attention.

"Minister, I have collected and sorted it out, and this hot stamping has indeed been used a lot in Europe."

"Volkswagen's new Passat and Audi A6 models all use some hot-stamped parts."

"However, up to now, no manufacturer in China has built a hot stamping production line."

"In this case, Cao Yang's claim that Nanshan has mastered hot stamping technology is grandstanding and has no credibility."

Yan Weiping has been busy looking for information these days.

Liu Darui assigned him homework and asked him to investigate the development of hot stamping at home and abroad.

Of course, what the reason is, he is naturally clear.

"Do you think that Cao Yang's hot stamping in the paper is the future of automobile stamping, how credible is this?"

Liu Da Ruishi is completely different from hot stamping.

If hot stamping is the future, then he has to worry about whether his position as the head of the technical department is solid.

"It's not a big deal, but it doesn't mean much."

"Just like new energy vehicles are the future of automobiles, everyone knows this."

"But whether it's a hydrogen car or an electric car, few of them are really mass-produced."

"I can also say that high-strength, lightweight technology is the future in the future, but what's the point?"

"So far, the models produced by Volkswagen and Toyota have not used hot-stamping parts, whether they are production models or new models that are being introduced."

"Even if it is to be used in the future, it will be done step by step, and it will not be used on a large scale at once."

"So I don't think there's anything to worry about, cold stamping will still be mainstream in the next decade."

Yan Weiping gave his judgment with great certainty.

The more I know about hot stamping technology, the more I feel that this technology cannot be popularized so quickly.

There are many domestic manufacturers that produce the heating furnace.

However, the heating furnace used to process hot stamping parts is being studied by Schwarz and Benteler in Europe, and other manufacturers are not able to do it.

The press that corresponds to the particularity of hot stamping is currently the best done by AP&T in Europe, and other manufacturers have not focused on it, or have not broken through this technology.

After all, compared with cold stamping, hot stamping needs to maintain pressure in the process.

This requires a completely different control logic from that used in cold stamping.

As for the mold, because it involves the quenching process after heating, the inside of the mold is made of water.

As a result, the processing of the mold becomes very complex and difficult.

This is also the reason why the cost of hot stamping dies is much higher than that of cold stamping.

And compared with cold stamping, after the hot stamping parts are processed, it is necessary to use a laser cutting machine for the trimming process, which requires the introduction of special laser cutting equipment.

In total, Yan Weiping feels that investing in a hot stamping production line now will cost at least 50 million, or even hundreds of millions.

With such a large investment, how low can the cost of hot stamping parts be?

Based on these circumstances, Yan Weiping is not optimistic about hot stamping in the short term

"If you pay more attention to the movements in the industry, hot stamping technology is also a hot technology and advanced technology on the car body after all."

"When the time comes, if the group leader or the company leader asks, we won't be ignorant."

It is obviously impossible to engage in hot stamping in a short period of time.

But Liu Darui also felt that it was necessary to take precautions.

Otherwise, you will be passive at that time.

……

"Dai Gong, did Nanshan study hot stamping technology before?"

In the west wind mold punch, Liu Wei was very curious to find Dai Shanhua with a copy of the "Huaxia Automobile Stamping" magazine.

Since Zhang Fugui and Dai Shanhua did ideological work, he took advantage of the trend to join Xifeng Mouchong and became a business backbone.

During this time, he also made some achievements.

The mold design level of Xifeng die punching has been improved to a certain extent.

Of course, in order to avoid the situation of teaching apprentices and starving to death of the master, Dai Shanhua has always cherished words like gold and is unwilling to teach other people in the west wind.

Even when people came to ask for advice, he always said something that seemed to be right.

"Minister Liu, Nanshan has done a lot of research on PRG molds before, and it is the first time I have heard of hot stamping dies."

"But they were able to make PRG dies like nut plates, and now they can make hot stamping dies, so it's not impossible at all."

What Dai Shanhua said this time was really true.

He really didn't know that Nanshan also had research on hot stamping.

At least he hadn't heard anything about it while he was there.

"Is there a way you can ask around and see how their technical research is going on in this area."

"Is there any possibility for us to cooperate?"

"After all, this hot stamping technology can be used not only in passenger cars, but also in some other special vehicles."

As a subsidiary of the Westwind Group, Westwind Die Punch is clearly not only a manufacturer of parts for passenger cars.

Some parts on commercial vehicles are also produced.

Even some special-purpose vehicles are produced by Xifeng Automobile Group.

Others think hot stamping is just a hot topic, but for Liu Wei, it is likely to be a technology that can be used for his own benefit.
