In the next two days, Duan Yun was still busy with the transformation of the second carburizing furnace of the labor service company.

The volume of the labor service company is not large, and the production capacity is always a bottleneck problem, so in order to maximize the interests of the enterprise, it is necessary to take the high-end route, some trivial, low-tech gearbox parts are contracted to the main factory and other cooperative manufacturers, and the labor service company only does the most difficult key gear parts, as well as the final debugging and assembly work, relying on the core technology to get the largest profit of the entire product chain.

The two core technologies of Longteng gearbox are finishing and heat treatment.

At present, there are not many enterprises using carburizing furnaces in China, and the carburizing furnace after the transformation of Duan Yun is in the leading position in China in terms of performance, and the heat treatment process of some key components is also tested repeatedly by Duan Yun, and a lot of raw materials are consumed in exchange, and the core gear parts produced have excellent performance, and the overall performance is much higher than that of similar products of other domestic manufacturers, and Duan Yun himself secretly modified some electronic meter temperature display functions of the carburizing furnace, that is to say, the temperature displayed on the instrument and the actual temperature in the furnace are dozens of hundreds of degrees of temperature difference, and this temperature difference is only mastered by Duan Yun, that is to sayEven if other manufacturers poach the technicians in the factory in the future, Duan Yun will not worry about real data leakage.

The labor service company takes the route of the upstream of the product chain, and Duan Yun's electronics factory also takes this route.

Once the product is on sale, then its technology is actually in an exposed state, in order to prevent domestic and foreign manufacturers from copying their own subwoofers, Duan Yun also tried some hard work.

Because Duan Yun has obtained a stable supply channel of Ne555 chips through the Xiamen office, and this kind of chip is difficult to buy by other domestic manufacturers, so domestic manufacturers want to imitate the subwoofer speakers produced by their factories through reverse technology, and they will not be able to produce them in large quantities due to the lack of key components.

is also limited to production capacity, Duan Yun handed over part of the subwoofer assembly process to the three local electronics factories in Daxing, and his own side controls the key chip welding and speaker shell production and assembly and debugging tools, mastering the upstream of profits.

With the first batch of more than 1,000 speakers sent to Guangzhou during this period, the labor service company also has nearly 800 Longteng automobile gearboxes out of the factory, and the factories on both sides have entered a stable and rapid development route, and at this stage, Duan Yun can finally breathe a sigh of relief and devote more time and energy to the research and development of new products.

Every night, as long as Duan Yun doesn't go to class at night college, he will sit in front of the computer to design circuit boards and new gearboxes.

With CAD software and printers, Duan Yun's design efficiency is much faster than before, basically an idea, and then tap the keyboard for a while, and the drawing is completely printed.

Duan Yun's technology in using this computer is becoming more and more proficient, he has fully adapted to it, there is no mouse, there is no computer operation of the windows system, because there is no Chinese system, the drawings printed by Duan Yun can only be marked with English and Arabic numerals, which looks more like manuals for European and American products.

However, none of this matters, the important thing is that it saves a lot of time compared to hand-drawn paper, which can speed up the time of product replacement.

However, Duan Yun also knows that any well-known company in the world has a huge and high-quality design team, and Duan Yun's ability is limited alone, even if he was a doctor in his previous life, it is difficult to support the building alone.

In fact, at present, he independently designed subwoofer audio and Longteng gearbox products have been regarded as personal ability to play to a certain limit, as far as the car gearbox is concerned, with Duan Yun's current level, by learning from similar foreign products, the design of manual transmission can still be done, but if you want to design a new set of automatic gearbox with performance leading the international level of similar products, this is a difficult task to complete.

Moreover, in the future, the international automobile market product technology changes rapidly, and without an efficient and strong design team, Duan Yunchang's products will soon be eliminated by the market, at most, they will follow behind and drink a bowl of soup through imitation and plagiarism, and sometimes they can't even drink the soup, the market is so cruel.

The high-tech team must have high-level talents, but Duan Yun has always been worried about the lack of highly educated talents in the factory, although the academic background does not represent the ability, but the people who have gone to the university will be far stronger than the average person in terms of knowledge and vision, especially in this era, who can be admitted to the technical secondary school and university from thousands of troops and horses, is undoubtedly not a master among the masters, and is far stronger than the gold content of college students in later generations.

This time, the provincial department sent 5 secondary school students and college students to Duan Yun at one time, which was a relief for him, which also meant that Duan Yun finally had the ability to form a research and development team.

On Thursday morning, Duan Yun came to the factory early, and then arranged for the people of the propaganda department to set up gongs and drums at the gate of the factory, put up a welcome banner that had been prepared for a long time, and then drove two 212 jeeps with the army of apprentices to the train station.

"Hold the sign high, or people won't see it. At the exit of the train station, Duan Yun motioned to the army next to him to hold up the stop sign with the names of the five college students a little higher, while his eyes were staring at the crowd pouring out of the station entrance, with a bit of enthusiasm in his eyes.

"Master, are there a few of them?" At this time, the army pointed to the front, and the five young men who were walking in a group not far away said to Duan Yun.

"Go over and take a look!" Duan Xue waved his hand when he heard this, and the two of them immediately walked up quickly.

"Comrade, are you college students who have come to report from the Red Star Labor Service Company?" asked the first army to rush forward to the group of young people.

"yes. The leader was a tall and thin young man wearing a pair of black-rimmed glasses, and after glancing at Dajun and Duan Yun, he immediately asked, "Are you from the Red Star Labor Service Company?"

"That's right, I'm Red Star Labor Service Company, and this is Duan Yunduan, manager of our Labor Service Company, welcome to you. Dajun introduced to a few people with a smile on his face.

"You are Duan Yun, the manager of the labor service company, why are you so young?" asked a petite girl who was following the young man with glasses at this time.

And the few young people next to him, after hearing that Duan Yun was the manager, looked at him with suspicion.

In fact, these 5 secondary school students and college students didn't know much about this factory before they came to Red Star Labor Service Company.

They just listened to the staff of the provincial department to introduce that the Red Star Labor Service Company is a key foreign trade enterprise in the province, and the Longteng automobile transmission products of this factory have won the national gold medal before, and it is a very famous enterprise in Daxing.

It's just that what they didn't expect was that the manager of this factory was so young, and judging from his face, he was in his early 20s, younger than their age......
