Rebirth 99 to become a car giant.

Chapter 173 Graduation thesis like an advertisement

Nanshan Industrial Park was put into operation, but Cao Yang couldn't take any time off.

No, Xiang Changle urged him to hand in his paper.

Fortunately, Cao Yang was not unprepared.

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

As a researcher in the automobile industry, although Xiang Changle is not specialized in body design, he has a good understanding of the various parts of the vehicle.

"Xiao Cao, I have seen some related introductions to this hot stamping technology in journals, but there shouldn't even be a hot stamping line in China right now, right?"

"You directly said in your paper that Nanshan Technology Co., Ltd. has mastered a complete set of hot stamping technology and strongly promoted the application of this new technology in automobiles. Will you offend many people?"

Xiang Changle sees things differently from Cao Yang.

The current large-scale stamping manufacturers in China are basically subsidiaries of various automobile groups.

Only some not-so-important brackets and other parts have the opportunity to be given to private enterprises.

For example, Yangcheng Huaqiang Stamping Factory, if the foundation of Yangcheng Automobile Group was not too weak and it did not have a competent parts subsidiary, Yangcheng Honda's stamping parts business would definitely not be in his turn.

Now Cao Yang is advocating a technology that none of these domestic companies have mastered to replace the traditional cold stamping technology. This is a job-killing behavior.

When the time comes, Spring City Stamping, Sihuan Stamping, Modu Tuonei, Xifeng Die Stamping...

How much do these factories hate Nanshan?

Domestic companies have not mastered this technology. If the OEM wants to use it, it can only be done by international auto parts companies.

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 on the car body are suitable for hot stamping, and the directions of each OEM will not be exactly the same."

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

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

"For example, the Yangcheng Apex and Yangcheng Aiji that Yangcheng Honda is planning to adopt, their parent company already has cold stamping technology for processing 780mpa and 980Mpa, and has even been widely used in the latest models."

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

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

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

Cao Yang knew that in the future there would be so many parts on the car body that competition would be fierce.

That is to say, the profit of hot stamping is relatively considerable.

It is a promising industry for at least the next ten years.

Although Nanshan has no plans to enter hot stamping parts, Huaqiang Factory can do it.

More importantly, Nanshan can make considerable profits from this industry by selling hot stamping presses and hot stamping molds.

Generally, a set of molds costs RMB 100 million, which is considered very expensive.

In later generations, the unit price of most stamping dies for auto parts did not exceed 50.

And what about the molds for hot stamping parts?

Before 2010, a set cost about 1000 million!

Even in 2020, it will be several million.

If hot stamping was started in advance, Nanshan, which was the first to master the production technology of hot stamping molds, would be able to eat the fattest piece of cake.

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

"If you publish this paper, it will be okay if no one pays attention to it."

"If it spreads on a large scale, it will put a lot of pressure on Nanshan."

"I think it's okay to publish it in the school magazine before the time comes?"

A normal undergraduate's paper is naturally copied here and there.

At this time, there was no such thing as checking for plagiarism in undergraduate thesis.

It's almost enough to fool him.

Anyway, the university adheres to strict rules and strict policies, so it is rare for students to fail to graduate.

I have never even heard of undergraduate students who were unable to graduate because they failed to pass their thesis.

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

Now after seeing the content, I feel a little hesitant again.

Because this paper is more like an advertisement for Nanshan than a paper.

The entire article does not introduce too specific technical information, but instead constantly emphasizes how Nanshan has conducted in-depth research on hot stamping.

He, Xiang Changle, is too embarrassed to promote such a paper.

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

"It will be widely used in the next 20 years, or even the next 30 years."

"I also hope that related manufacturers can accumulate technology in this area in advance."

“If you have any difficulties, you can come to us in Nanshan for cooperation.”

"This is actually a good thing for everyone."

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

But this will cause huge problems after sales.

So even in 2023, there will be few models in use.

To put it bluntly, integrated casting technology transfers the risks of reduced OEM costs to consumers or insurance companies.

It is a cost reduction plan that does not involve a special person in charge.

"You boast so much that someone will believe you when the time comes."

Although Xiang Changle knew about Nanshan's technology and thought the company was quite powerful, he was also proficient in hot stamping technology, so he was 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, just make sure that the strength and parts accuracy meet the requirements, and it will be proven to be qualified."

"Even if we want to cheat, there is no way."

Seeing how confident Cao Yang was, Xiang Changle gritted his teeth and prepared to follow this disciple's "mischief".

Soon, he used his connections to submit the article to "China Automotive Stamping".

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

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

Although few people have heard of it, this magazine has a high influence in the domestic automotive stamping industry and is widely included in the Huaxia Academic Journal Online Publishing Database, the Huaxia 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.

State-owned enterprises such as Xifeng Die Stamping and Chuncheng Stamping have some paper requirements when recruiting technical personnel for professional titles.

Even if it’s not a must, it’s still a plus.

In this case, everyone naturally has to find a way to publish a paper in a magazine.

I also pay close attention to the news in the industry.

As stamping parts, what everyone paid most attention to in the past was mold design.

How to prevent parts from cracking and wrinkles are all related to mold design.

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

As the technical director of Spring City Stamping, Liu Darui naturally pays close attention to the magazine "China Automotive Stamping".

Cao Yang's article is so unconventional and completely different from other people's articles.

Under such circumstances, it would be difficult for Liu Darui not to pay attention to him.

"Minister, I collected some information and found that hot stamping has indeed been used a lot in Europe."

“Volkswagen’s new Passat and Audi A6 models all use some hot stamping parts.”

"But so far, no domestic manufacturer has built a hot stamping production line."

"In this case, Cao Yang claimed that Nanshan has mastered hot stamping technology. I think it is grandstanding and has little credibility."

Yan Weiping has been busy looking for information these days.

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

Of course, he knew exactly what the reason was.

"You think Cao Yang said in the paper that hot stamping is the future of automotive stamping. How credible is this?"

Liu Darui is completely different from hot stamping.

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

"There's no big problem with this, but it doesn't mean much either."

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

"But whether it is hydrogen energy vehicles or electric vehicles, few of them have truly entered mass production."

“I can also say that high-strength, lightweight technology is the future, but what’s the point?”

"So far, the models produced by Spring City Volkswagen and Spring City Toyota, whether they are mass-produced models or new models being introduced, do not use hot stamping parts."

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

"So I don't think there's anything to worry about. Cold stamping will still be mainstream in the next ten years."

Yan Weiping gave his judgment with certainty.

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

As for heating furnaces, many manufacturers in China produce them.

However, Schwarz and Benteler in Europe are currently researching heating furnaces used to process hot stamping parts, and other manufacturers are still unable to do so.

As for the press that corresponds to the special characteristics of hot stamping, Europe's AP&T is currently the best. Other manufacturers have not focused on it, or have not made breakthroughs in this aspect of technology.

After all, compared with cold stamping, hot stamping requires pressure maintenance during the processing process.

This requires that the control logic of the press is completely different from that used in cold stamping.

As for the mold, since it involves quenching after heating, there are water channels inside the mold.

This makes the processing of the mold very complicated and difficult.

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

And compared with cold stamping, after hot stamping parts are processed, a laser cutting machine is required for trimming, which in turn requires the introduction of specialized laser cutting equipment.

After all, Yan Weiping felt that investing in a hot stamping production line now would cost at least 5000 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 the short-term success of hot stamping.

"You should pay more attention to the news in the industry. After all, hot stamping technology can be regarded as a popular and advanced technology in automobile bodies."

"If the leaders of the group or the company ask about it then, we won't be in the dark about everything."

It is obviously impossible for Spring City Stamping to engage in hot stamping in a short period of time.

But Liu Darui also felt that it was necessary to prepare for a rainy day.

Otherwise, I will be passive by then.

……

"Gong Dai, has Nanshan ever researched hot stamping technology before?"

Inside Xifeng Diechang, Liu Wei came to Dai Shanhua out of curiosity with a copy of "China Automotive Stamping" magazine.

Ever since Zhang Fugui did ideological work with Dai Shanhua, he followed the trend and joined Xifeng Muchong and became a business backbone.

During this time, he did achieve some results.

The mold design level of Xifeng Die Punching has been improved to a certain extent.

Of course, in order to avoid teaching his disciples and starving the master to death, Dai Shanhua has always cherished words like gold and was unwilling to teach others in Xifeng.

Even when people come to ask for advice, he always says something that seems to be correct.

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

"But they can make PRG molds like nut plates, and now they can make hot stamping molds, so it's not impossible."

Dai Shanhua really told the truth this time.

He really didn't know that Nanshan also researched hot stamping.

At least he didn't hear anything about it when he was there.

"Is there any way you can inquire and see how their technical research in this area is going?"

"Is there any possibility for us to cooperate?"

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

As a subsidiary of Xifeng Group, Xifeng Die Stamping obviously does not only produce parts for passenger cars.

Some parts for commercial vehicles are also produced.

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

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