Chapter 7 Only with strength can you speak with confidence

"Director Cao, if we don't understand your production process, how can we confirm whether the parts you produce meet the drawing requirements?"

"When we go to inspect various manufacturers, we naturally need to take some photos. Otherwise, how will we prepare a business trip report?"

"You can't even meet such a common request?"

Before Bu Defan could speak, the buyer next to him, Li Jianfeng, jumped out.

Although Modu Volkswagen is a joint venture, in order to ensure that the localization of parts does not affect the quality, all localization proposals require the approval of the German resident.

In many cases, Volkswagen has a greater say than the Modu Automobile Group.

When Li Jianfeng saw Cao Yang embarrassing his boss, he naturally had to step forward.

However, this time, maybe he will be disappointed.

"Mr. Bu Defan, Mr. Li, our nut plate innovatively uses the PRG process. The process design of this set of progressive dies is unique in the country and even the world. It includes the nut plate processing process at our Nanshan Auto Parts Plant.

All kinds of know how.”

"Both experts must be very clear that this part uses the TDM process in Germany, and is gradually stamped through a set of single-process dies before it is finally produced."

“Although the parts are very small, since the bosses need to be punched out on the T3.5 hot-rolled plate and threads are tapped on the bosses, as long as the mold design and process layout are slightly unreasonable, the parts will crack or the thread accuracy will be inaccurate.

conditions that meet the requirements.”

"There is a huge difference between these two processes in terms of production efficiency and production cost. Our Nanshan Auto Parts Factory can reduce the price of an imported part that costs more than ten yuan to the current level because of the craftsmanship of continuous research."

"So I'm sorry, you can visit the entire process flow of this nut plate. You can also take pictures of other factory equipment except the mold. But this set of molds can only be viewed but not photographed."

When Cao Yang was explaining there, Zhang Fugui, Cai Rong and others next to him were breaking out in cold sweat.

If it weren't for their own boss who stood up to stop him, and the boss personally designed this set of molds and guided the workers to process it, they would never have allowed Cao Yang to act so randomly.

After all, for someone who has offended the people of Shanghai, is there any hope for future orders?

Without orders, if the factory goes bankrupt, they will be in trouble too.

The audit experts of Shanghai Volkswagen can be said to be key figures in the life and death of the Nanshan Auto Parts Factory.

How can you be so rude?

"Okay, that's very well said!"

"The spirit of craftsmanship, I like it!"

"This process innovation is very valuable!"

"If your quality is very stable after mass production, I will help you promote this nut plate to the global public."

Bu Defan applauded and said something with a slightly weird accent.

Obviously, Cao Yang's obstruction not only did not make him angry, but actually left a deep impression on him.

Although he is a manager in the purchasing department, his father is a senior employee at the Volkswagen headquarters, working his way from quality engineer to purchasing director.

Therefore, he has a very deep understanding of the spirit of craftsmanship.

He visited many domestic parts factories before, but none of them mentioned the spirit of craftsmanship to him, and he never saw any factory whose workmanship was better than the original factory in Germany.

After localization like the Nanshan Auto Parts Factory, not only the cost has become lower, but the technology has become more advanced, and there is no such thing.

More manufacturers are using labor cost advantages to localize imported parts. Compared with imported ones, the technology will only fall further behind.

Those who can completely maintain the same level of German craftsmanship are already top students.

There is no way, China's auto parts industry before 1999 was at this level.

There is absolutely no intention to blackmail your business partners.

"Thank you, Mr. Bu Defan, it's great that you can understand us. This is the inspection data of each batch of our parts. All dimensions are within tolerances, and the CPK value can reach 2.1."

When Cao Yang said this, the quality manager Dr. Hassan next to him became interested.

After all, he is professional in this matter.

"Can your CPK value reach 2.1? Are you sure your calculation is correct? I have inspected so many domestic manufacturers, and most of them cannot even reach the passing line of 1.33. There are very few that can achieve the excellent indicator of 1.67. As for 2.0

I haven’t encountered any of the above.”

With the help of the translator, Dr. Hassan took the test form from Cao Yang.

Before coming to Nanshan Auto Parts Factory for inspection, he had specifically seen the drawing of the nut plate, and naturally kept the tolerance requirements in mind.

When he was at the German headquarters, he also visited the site of the nut plate supplier and had some impressions of the relevant data.

Obviously, the set of data in his hand was almost fake compared to what he remembered.

So neat!

So consistent!

"Director Cao, I want to confirm, are these data measured from different parts, or are they the result of multiple measurements of the same part?"

Obviously, Hassan had doubts about the data in his hands.

"Dr. Hassan, we have ready-made measurement tools and parts here. I think directly extracting a few parts, measuring a few parameters, and then comparing them with the data in your hand may be more convincing than my answer."

Although Cao Yang's face is still a little immature, it is full of confidence.

This set of molds was designed with the help of the system, so it’s no wonder it’s not good.

Some time ago, he spent almost every day in the factory, watching the workers processing molds, in order to mass-produce nut plates as soon as possible, so as to earn money and gain points, which can be used to exchange for new parts technology.

Otherwise, if the system disappears one day and you miss the opportunity to exchange for more parts, you will cry to death.

The development of China's automobile industry is relatively slow, especially parts companies, and the gap with the international market is very large.

Even in later generations, China's automobile production has ranked first in the world for many years, but there are not many Chinese companies on the top 100 global auto parts list.

China is a big automobile country, but it is not a strong automobile country.

After his rebirth, Cao Yang had a wish to change this situation.

"Okay! This is the best."

After Dr. Hassan finished speaking, he personally picked up a few nut plates, went to the inspection table next to him, and carefully inspected them with a vernier caliper.

Since he only randomly checked a part of the dimensional data for measurement, which only took a few minutes, Dr. Hassan stopped.

Apparently, Dr. Hassan already has the answer.

PRG mold, also called progressive die, also called continuous die (it is said that continuous die will be canceled in the standard terminology), is composed of multiple stations. Each station completes different processing. Each station is sequentially related. In one stroke of the punch press

A series of different stamping processes are completed in the process. After one stroke is completed, the punch feeder moves the material forward according to a fixed step, so that multiple processes can be completed on one mold, usually with punching

, blanking, bending, trimming and other processes.
