Chapter 571 Are the Japanese cheating?

As the chief designer, it is reasonable for Chang Haonan to answer some of Party B’s suppliers’ doubts.

However, today’s occasion is really not suitable for a long speech. In addition, time and conditions are limited, so it is impossible to answer each one in detail.

Furthermore, the commander-in-chief of the scene was Yan Yongnian, so he should have been responsible for this job.

Therefore, after showing off his skills, Chang Haonan just wrote down a few issues that were more critical or that he was more interested in.

For example, as someone just mentioned, guiding the determination of the casting process of large castings through numerical calculation is essentially a multi-field composite problem of temperature field and stress field.

This is not only the research direction of Chang Haonan's next plan, but also one of the difficulties that must be overcome when the turbofan 10 is put into production.

Because essentially, the production of turbine disks and turbine blades is also a casting process that controls single crystal growth.

As for those parts that are relatively easy to solve or are not very important, it can only be done by Yan Yongnian and Liao Xinhua.

Immediately afterwards, it transitioned to the next topic.

That is, the selection and supply of second-tier suppliers.

"This part is all paper information and has nothing to do with the on-site situation. Let's go and talk in the car?"

Chang Haonan suggested.

It’s still a little cold by the river in April.

I didn't feel it when I first came here, but after standing here for a long time, it really felt a bit biting.

Now that Party A's father had spoken, the meeting venue was moved from the semi-completed construction site to the minibus that Chang Haonan had just arrived in.

Although there are not many positions, not all Party B has the problem of second-tier suppliers. For example, Baoshan Iron and Steel completes everything from ore smelting to finished product welding by itself, so naturally there is nothing to report.

All in all, it was a bit crowded, but I could still sit down.

"Mr. Chang, according to your requirements, our selection of suppliers is based on optimization of supply efficiency. There are no mandatory requirements in terms of cost and localization."

Yan Yongnian handed a compiled form to Chang Haonan and said at the same time:

"However, considering that the die forging press project has a significant impact and is planned as a gift for the 50th anniversary of the National Day, no mistakes can be made. Therefore, we have arranged AB backup for most of the second-tier suppliers. Even if the first choice is If the problem is solved, I can launch alternative plans as quickly as possible.”

Chang Haonan nodded with satisfaction while looking at the reports in front of him.

Yan Yongnian's performance in mechanical design can only be considered average, but when it comes to engineering practice, he is indeed very thoughtful.

"Although the localization rate of this project itself is not the highest priority, the localization of imported parts and components must be replaced as soon as possible."

Chang Haonan raised his head and looked at the representatives of Party B sitting around him:

"The industrial scale of our country is developing very fast, especially now that there are no policy restrictions. Therefore, it is impossible for a heavy-duty die forging press to just manufacture this single machine, and your business will be indispensable in the future."

"What's more, there are all kinds of other heavy equipment, such as large cranes, loaders, shield equipment, mining equipment, etc., there are too many to count. As long as it is equipment that currently needs to be imported from abroad, we have it domestically. There is room for manufacturers to develop, even if it is not a project that our Equipment Industry Department focuses on, they still need to find suppliers. When the time comes, you will start early, have a complete range of products and low prices, and you will definitely be a stable first-tier player."

These words are no longer just a matter of fact.

Basically, it points out the way for these enterprises that have just switched from the Ministry of Machinery Industry to the Commission of Science, Technology and Industry for National Defense, and their business may not be stable.

Some people who reacted quickly have even taken out their notebooks and written down the categories that Chang Haonan just mentioned casually to give examples.

After all, this is likely to be the next wave of trends in the machinery manufacturing industry.

If you can catch it, you will take off instantly.

It has been almost a month since the Equipment Industry Department was established.

Anyone with a discerning eye can almost see that the relationship between the director and Chang Haonan is very close.

However, most people still subconsciously felt that it was Lan Xinzhi who wanted to use the latter's mouth to deploy the work of the Equipment Industry Department.

But there are still a few people who have glimpsed some truth and realize, or at least begin to suspect, that the actual situation may be completely opposite.

However, Chang Haonan didn't pay much attention to the mental activities of others. He just continued to look at the form in his hand, circling some places involving imported raw materials or parts from time to time, and making comments next to them.

For example, "We need to focus on development in the future", or "This part of the market is too small, there is no need to use state power, just leave it entirely to the market" and so on.

Soon, he noticed a place that was different from the previous one.

"In this section, why is it not stated who is A and B among the two suppliers?"

Chang Haonan picked up the form and pointed to a parts supplier of the main shaft gearbox and asked.

Hangcheng Gearbox Group Co., Ltd. is responsible for the production of gearboxes for forging presses. Its main business is the production of marine power gearboxes. After being assigned to the Equipment Industry Division, it also began to engage in other businesses.

Hangge’s representative quickly gave an explanation:

"This is the crossed cylindrical roller bearing in the gear box. Regardless of priority, the plan is to use a 50:50 ratio to assemble products of the same brand number from Bingcheng Bearing Group and Japan's NSK Group."

This gameplay directly stunned Chang Haonan:

“Won’t the series installation of products from different manufacturers affect the stability of the gearbox’s working condition?”

Under normal circumstances, standard parts such as bearings, gears, screws and nuts involve too many processes, so even products of the same specifications produced by different manufacturers, or even products from different batches of the same manufacturer, even if they all meet relevant standards, But there will also be some nuances.

Therefore, unless there is a need other than technical reasons, serial assembly of parts from different sources is rarely chosen.

"That's it."

The other party quickly explained:

“NSK has always been the main supplier of our Hangzhou gear factory in the past, but this time, during the bidding process, we found that the performance of the samples submitted by Ice Axis Group and NSK were almost identical, as if they were produced using the same process. And domestic parts are cheaper.”

"In this case, we should have directly designated Ice Axis as the priority supplier, but we were still worried about whether there would be any non-technical problems. After all, the consistency was really strange, so we signed two supply contracts at the same time. If there is no problem with Ice Axis’s products, we will gradually start to cooperate with them later. If other problems are found, there is still room for recovery, so as not to delay the progress of the forging press project.”

"Non-technical question?"

Chang Haonan was stunned by this statement.

The man had no choice but to continue:

"In this matter, we can only speculate that Bingxian Group technically referred to NSK's process, but in what form this reference was carried out... it is really impossible to determine..."

Now Chang Haonan understood.

I am worried about the legal risks related to intellectual property rights.

In fact, for those who don't know the inside story, there is nothing wrong with this kind of worry.

Everyone knows what level your Ice Axis Group has been in the past.

It had only been a year since I last saw it, and I took out a sample from my crotch that was on par with top foreign manufacturers, and even the details of the performance indicators were so consistent.

Everyone has to make some noise in their heart.

But the problem is that Chang Haonan knows the inside story.

He even sold Ice Axis Group’s technology to them.

Although the product developed at that time was a bearing set for turbofan 10, others also had subjective initiative. More than half a year has passed, and it is not surprising to come up with something new by drawing inferences.

In short, there is absolutely no need to risk copying others.

"Are you sure that the test results are almost exactly the same?"

Chang Haonan confirmed again.

The other party nodded:

"To be sure, we also specially found two third-party organizations to conduct blind tests, and the final report conclusions are the same."

Hearing this answer, Chang Haonan took a deep breath and made a tactical retreat.

At the same time, I already had a conclusion in my mind——

The counterfeiter is NSK Group...
