Duan Yun knew that what should come would always come, and if he wanted to get anything, he would have to pay a price.

But fortunately, he was prepared for this.

In the next two days, Duan Yun stayed in the newly built plant every day, urging workers to cooperate with the manufacturer's technicians to install and debug the equipment.

The installation and commissioning of the new equipment is going very smoothly, the new home house has been fully closed, the ceiling work has been completed, and the small plant next to it has also reached the final stage, Duan Yun and the construction team negotiated, the other party agreed to build a row of toilets next to the new plant, using the remaining bricks and cement of the plant.

Most of the new plant is currently empty, and some equipment has not yet been shipped, including the most critical carburizing furnace.

In fact, there are not many manufacturers that can use carburizing furnaces in China, and even the Red Star General Factory does not have this kind of equipment, and the original equipment can be used without modification, but Duan Yun has formulated a modification plan in advance in order to improve the core technology competitiveness of his new products, using the successful experience and technology of the previous life.

In addition to supervising the installation and commissioning of new equipment by workers in the workshop, Duan Yun also organized members of the technical research team to study and discuss, he wanted to bring out a high-level technical team in this factory, so when he lectured to these people, he also taught them some advanced machining professional technology in this era.

But Duan Yun has always been hidden, and he will definitely not talk to these technicians about some of the more advanced technologies in later generations, especially the technology of refitting the carburizing furnace and the technology of integrated circuits, which are the key to his control of the core technology of this enterprise.

In addition, in the study and discussion with the public relations team, Duan Yun also took out a lot of information that he had just mastered, including some product drawings of the "three major and three small" automobile manufacturers in the country, as well as the product information and manufacturers of the four major automobile assemblies.

Duan Yun was able to obtain these materials, and Zhao Changfeng could be said to have made a great contribution.

Zhao Changfeng's head is the name of the business representative of the sales department of the Red Star Labor Service Company, and he goes to major manufacturers across the country to promote the products of his factory, but he is actually doing things to obtain the production materials of various manufacturers.

Only by knowing oneself and knowing one's opponent can one not be defeated.

In these years, there was no such thing as "commercial espionage", because they were all going through a planned economy, and there was no complete patent law in China so far, and the production of technical materials and products was uniformly dispatched, and the confidentiality of some production technical materials was not high among enterprises.

This gave Zhao Changfeng a chance.

Since several large domestic automobile companies belong to the Ministry of Industry, the Ministry of Light Industry is unable to obtain the information of these manufacturers, so Duan Yun can only come up with such a strategy.

Zhao Changfeng has traveled frequently in Beijing, Shanghai, and Tianjin in the past two months, and has not sold a single piece of automobile transmission products, but has obtained a large number of manufacturer information through various channels.

Zhao Changfeng usually doesn't smile, it seems to be a little wooden, but this is just his performance, in fact, Zhao Changfeng himself is very flexible, and like his father, he has a very good eloquence, knows how to improvise, and does things in an eclectic way.

When he went to various automobile factories to sell, he tried every means to get the names of the directors of the information departments of these factories, and then stood at the gate of the factories every day, and after seeing the directors of the information departments, he went up to the front and found all kinds of excuses to invite the other party to drink and eat, and then gave the other party some benefits and obtained copies of the relevant information of the manufacturer.

It's not easy to do this kind of thing, and people are usually wary of strangers' overtures, but Zhao Changfeng's eloquence, looks, and patience helped him.

Zhao Changfeng is polite and polite, he has a habit of cleanliness, he is dressed in a blue tunic, he wears a straight and clean suit, his hair is also meticulously combed, and he also speaks and talks with the demeanor of a cultured person, which is easy to give people a good impression.

Zhao Changfeng said that the information is for his own study, this kind of excuse generally can't fool people, but Zhao Changfeng can always say that it is convincing, and there are many people who are not interested in him, but Zhao Changfeng is very patient, it can stand at the gate of the factory for a week and wait for the director of these data sections, and the shot is also very generous, as long as the other party is willing to copy the information and hand it over to him, then Zhao Changfeng will definitely give the other party good cigarettes, good wine, and even cash.

Of course, all this money came from the factory in the end, when Zhao Changfeng was in the field, he always kept in touch with Duan Yun through long-distance phone calls, as for what to eat and how much money to spend, Duan Yun made a decision, and Duan Yun spared no expense in order to obtain these materials, almost every time Zhao Changfeng went out, he had to spend hundreds of yuan on various expenses, and Duan Yun was reimbursed in full.

In addition, Zhao Changfeng has been able to succeed repeatedly, and there is an important reason for [Haitang Book House M] is that the information he wants is not strictly confidential information in the factory, and many things are even public on the manufacturer's side, so from another point of view, Zhao Changfeng's behavior is not illegal.

For more than two months, Zhao Changfeng basically got the design drawings of the main products of all important domestic automobile manufacturers, transmission procurement manufacturers, and the product information of these transmission manufacturers.

After sorting out these materials, Duan Yun found that the gearboxes supporting several major domestic automobile manufacturers are Tangshan Gear Factory, FAW Harbin Automobile Gear Factory, Chongqing Qingshan Gear Factory, Hangzhou Qianjin Gear Factory, Changchun Transmission Factory, Shaanxi Baoji Gear Factory, and Qijiang Gear Factory.

Among them, the three largest automobile transmission manufacturers are FAW Harbin Automobile Gear Factory, Shaanxi Baoji Gear Factory, and Qijiang Gear Factory.

Before the Daxing Automobile Factory used the transmission products produced by Shaanxi Baoji Gear Factory, the technical strength of this enterprise is still good, in addition to the Daxing Automobile Factory supporting the automatic transmission production of light vehicles, but also to Shanghai and Guangzhou Automobile Factory to provide automotive transmission products.

The other two automobile transmission manufacturers FAW Harbin Gear Factory and Qijiang Gear Factory are the national key transmission gear manufacturers that have been established for more than 30 years, especially Qijiang Gear Factory, in September 1952, has produced China's first batch of automobile gearboxes a total of 11 units, so far, it should be the strongest factory in the production of automotive transmission gears in China.

In addition, from the analysis of the product drawings of these manufacturers, the basic use of the Soviet Union automobile gearbox production technology, in the light vehicle gearbox, almost all of the use of the Soviet Union in the 50s of the last century gas 21 and Uzi 2101 model automobile transmission technology.

Relatively speaking, Duan Yun is currently copying the car transmission of the BA3-2101 Lada sedan. Technically, it is necessary to lead the products of other domestic automobile transmission manufacturers.
