It's the big guys, each one of them is huge, it's the size of a standard shipping container, it's just that the containers are metal, and these are wooden.

The huge wooden boxes, very new, were neatly placed in the factory, and the workers who were about to continue marking the line were stunned, and several technicians were also stunned.

Everyone stared blankly at these big guys.

Only Sun Xu reacted and smiled happily, if he didn't guess wrong, this should be the equipment for the production of IGBT.

At the last meeting, Tang Fei said in front of everyone that the production equipment for IGBT production is complete, and now it seems that the equipment has arrived!

Others thought that these devices were transported in from outside overnight, but in fact, Tang Fei took them out of the gift package rewarded by the system, and quietly put them here at night when no one was around.

Not only does this plant have a lot of equipment, but another plant is very amazing, and there is a very advanced lithography machine in the world today.

After understanding that these are production equipment, Sun Xu said loudly: "Let's work hard, finish the marking work, and our production equipment will be installed soon." ”

Seeing Sun Xu say this, someone finally reacted, and one of the technicians said: "Expert Sun, this... These are all equipment for the production of IGBTs!"

"Yes, this is part of the production equipment, they were shipped overnight last night and are about to be installed and commissioned. ”

Hearing such an answer, several technicians became excited one by one, everyone has worked hard for so long, busy with the design of IGBT in front, and now busy with the process layout in the plant, all of which is to make IGBT with independent intellectual property rights.

Now that the equipment is in place, it's in front of everyone.

So, everyone was full of enthusiasm to carry out the finishing work of marking in this plant, and a few days later, a professional equipment installation company came.

This is Jiuzhou Industrial Co., Ltd. invited from the provincial capital, by these professionals to carry out the unpacking of equipment, equipment installation and so on.

Of course, the technical experts of Jiuzhou Industrial Co., Ltd. will cooperate and guide. Inside the factory, it was busy.

The first large packaging box was opened, and everyone saw the equipment inside, which is a vacuum welding machine with advanced performance, one of the key equipment for the production and manufacture of IGBT.

Use a large crane to lift this equipment out and lift it to the designated position. The location of the equipment has been completely decided, and a few days ago, several technicians put up the signs.

"Wow, this device is not simple, it should be the best vacuum welder in the world at the moment!"

"yes, absolutely imported!"

"Jiuzhou Industrial Co., Ltd. is really good, they can also buy such equipment. ”

“……”

The people of this equipment installation engineering team are also not lacking in vision, after unpacking, they are surprised to see this advanced vacuum welding machine.

Knowing that it is difficult to buy this kind of imported equipment from abroad, they admired Jiuzhou Industrial Co., Ltd., and subconsciously believed that Jiuzhou Industrial Co., Ltd. must have a very strong background.

The second device is unpacked.

When everyone saw the equipment inside, there was another exclamation, because it was a very advanced surface sandblasting equipment, which is also an important equipment required for the production of IGBT.

With the installation of the equipment, a large packing box was opened, and after seeing the equipment inside, the people of the installation engineering team gradually became numb.

Because they see more advanced equipment today than they have seen in their lifetime combined, some of which they have even only heard of and have never seen before.

These equipment were unpacked and installed, and gradually, the huge plant was plumped up, and according to the requirements of the process layout, there were manufacturing equipment one by one.

The IGBT assembly line has also begun to be installed, which is a production line integrating IGBT parts assembly, packaging and testing.

The manufacturing process of IGBT generally includes: screen printing, automatic mounting, vacuum reflow soldering, ultrasonic cleaning, defect detection (X-ray), automatic wire bonding, laser marking, shell molding, shell filling and curing, terminal forming, and functional testing.

The above process steps can be fully realized in this production line. And the annual production capacity of this production line is at least 1 million high-power IGBTs.

In a flash, November passed and entered the last month of 98 years, that is, December.

Jiuzhou Industrial Co., Ltd. is preparing for the production and manufacturing of IGBT, such as the preparation of process data, the installation and commissioning of production equipment, the preparation of production materials, etc.

According to Tang Fei's instructions, while compiling the production process data of 6500V voltage level IGBT, Sun Xu and Tang Zhonghua also began to design other types of IGBT.

Other types of IGBT are the same as IGBT with 6500V voltage level in terms of design principle, to be precise, the voltage level is lower, the technical difficulty is lower, and the design of IGBT of other voltage levels is relatively easy.

A number of types of IGBT began to be designed, which is also the fifth generation of IGBT, which is mainly used in the rail transit industry.

After entering December, the whole Jiuzhou Industrial Co., Ltd. seems to be busier, working hard for the production of IBGT.

The Red Star Factory is also developing, as always.

In addition to the production and manufacture of Shaoshan series electric locomotives, the most, most important work is the trial production of DJ4 electric locomotives.

In September, the first DJ4 electric locomotive entered the car and was assembled in the assembly workshop, because the IGBT imported from abroad arrived smoothly and did not affect the entire assembly process, and the assembly progress of this car was not bad.

According to the plan, by March or April next year, the car will be able to be dropped.

The process of trial production of a new car is certainly much slower than mass production. For example, the Shaoshan series of electric locomotives mass-produced by Hongxing Factory, from the beginning of entering the car to the final drop-off, the production cycle generally only takes about half a month, while the trial production of new cars is much slower.

At the beginning, the trial production of Shaoshan Type 9 electric locomotive took several months for assembly in the assembly workshop alone. The DJ4 electric locomotive has a higher technical level and is more complex, and it is the first time to do it, even if there is a guide from Siemens' technicians, it also belongs to the type of "crossing the river by feeling the stones", and it will take several months for the first car to really get off the car.

The second trial-produced DJ4 electric locomotive also entered the train in late November, and it has also arrived at the assembly station of the final assembly workshop and has also started assembly.

Obviously, this is a bit faster than the scheduled plan.

There will not be many DJ4 electric locomotives produced in the trial production stage, only a few units, and the trial production plan has been prepared for a long time.

However, Siemens proposed that two more sets of the DJ4 electric locomotive should be added to the trial production, and in desperation, the Red Star Factory could only modify the trial production plan, not only to advance the entry time of the second car, but also to start to invest in the materials of the new trial car.

Domino effect.

The senior management of the Red Star Plant was opposed to adding two more cars, but Siemens insisted, and in desperation, the Red Star Plant had no choice but to agree.

Today is Monday morning, according to the usual practice, the senior management of the Red Star Factory is holding a weekly office meeting, which is presided over by Chang Jinlin, the number one leader. Obviously, this was an enlarged meeting, and some middle-level leaders of the Red Star Factory also attended, such as Chen Guihong.

In addition to discussing some recent matters, the focus was on the trial production of the DJ4 electric locomotive. Xie Zhenhua introduced the progress of the trial production of the first car and the second car, and also reported the feeding of the third trial car.

After Xie Zhenhua finished his report, Chang Jinlin looked around the entire conference room and said slowly: "Comrades, Siemens has asked to revise the trial production plan and add two cars. ”

At the meeting, Chang Jinlin specially said this matter, Chang Jinlin knew that such a change, the things involved are big, not only involving material procurement, feeding production, the key is to involve the procurement of many imported accessories, such as IGBT import procurement.

Last time, Chen Guihong turned the tide and purchased all the IGBTs needed for trial production, but such a modification of the trial production plan does not mean that two more IGBTs will be purchased.

Chang Jinlin felt that his head was big, and Chen Guihong was not, he was also a big head.

But at this point, the addition of two cars has become an ironclad fact, Chang Jinlin can only carry out a series of work deployment, such as the production and manufacturing system to prepare production plans, feeding, and start manufacturing. The procurement system carries out the procurement of spare parts, outsourcing processing and so on.

After the meeting, Chen Guihong returned to his office, took out a cigarette and smoked it, thinking about what to do.

Who made him the leader of the procurement center, and the procurement of spare parts belongs to his business scope. Last time, he quietly used the power of his family to successfully purchase the IGBT urgently needed for the DJ4 electric locomotive from overseas, and this matter was still known by his old man, but he was severely criticized.

What should I do?

Could it be that he quietly asked Uncle Liu for help, but if he let the old man know, then he would probably be criticized even worse.

No, you must not ask Uncle Liu for help again.

But soon Chen Guihong hesitated, his confidence began to waver, if he did not find Uncle Liu in private, he asked himself if he had the ability to purchase back the IBGT needed for these two cars.

What to do, what should I do!

Chen Guihong has a bit of a crazy taste.

A cigarette was smoked, and he didn't make up his mind. Pick up the phone on the table, think about it, put it down again, pick it up again after a while, put it down again, and so on.

"Oh, Brother Chen, why does it smell so much smoke in your office? ”

It was Tang Fei who pushed the door in, saying this while waving his hand in front of his nose to drive away the smell of smoke.

Tang Fei is here!

Today's three watches, the third watch is complete!
