When the factory was going to hold a technical transformation competition, many people speculated that Cheng Changlin, who was the chief engineer of the factory, would definitely participate, after all, there was no restriction on registration for this competition, and the prize money was also set very high.

After all, Chang Lin, the chief engineer, is undoubtedly the person with the highest education and the best design level in the factory, and he is a senior leading cadre in the factory.

But unexpectedly, when the factory announced the rules of the competition, the chief engineer Chang Lin publicly stated in the technical department that he would not participate in this technical transformation competition, and also encouraged other technical personnel to actively participate, showing a high wind and bright festival for the younger generations and young backbones!

Cheng Changlin's statement undoubtedly moved everyone in the technical department, and also greatly encouraged the enthusiasm of these young technicians to participate in the competition.

The 800 yuan bonus plus the nomination of the model worker, so that this group of technical school students who have just graduated from the technical school are like playing chicken blood, a change from the previous people floating, a cup of tea in the morning, a newspaper to read the style of the day, from the factory data room to find a large number of machine tool drawings and materials, began to draw the modification drawings.

These people are obviously inspired by the last Duan Yun modified SL lathe, and started the idea of modifying other machine tools, but most of the people's level is half-hanging, many technicians have been working in the factory for two or three years, and they have already lost the mechanical technology they learned from school.

In the final analysis, the so-called reference of these technicians is actually a kind of plagiarism, after all, the basic working principle of the lathe is the same, as long as you 'learn' the technology of Duan Yun to modify the old lathe, then a little improvement in the new lathe will become your own modification results.

These technicians in the technical department have some shortcuts to think carefully, and as the chief engineer of the factory, Cheng Changlin is light-hearted, and from time to time to the technicians who are drawing and designing in the afternoon, give some suggestions, and the words are full of encouragement and support for the young technicians, which also makes many technicians present somewhat moved.

At the same time, after Duan Yun came to his studio in the afternoon, he also began to design plastic molds.

The plastics used for electrical shells have high requirements for insulation, high temperature resistance, and hardness, and now Duan Yun can't get suitable materials, but the molds of these plastic shells can be designed first.

The shell of the antenna amplifier is still very well designed, and this small plastic shell does not have high requirements for insulation and heat resistance, so Duan Yun's design idea for this kind of shell is just to make it look high-end and beautiful.

When Duan Yun trained Cao Dong and others before, he had always asked them to pretend to be the maintenance personnel of the 'Toshiba' manufacturer, so when designing this kind of plastic shell, it was best to have the trademark of the Toshiba manufacturer to be convincing.

However, considering the danger of being investigated and dealt with as counterfeit goods, Duan Yun was a little careful when making molds.

He changed the traditional Chinese character Chinese the word '東芝' to a different position, and became 'Zhidong' after claiming that it was the Hong Kong and Taiwan version of the product, which needs to be read backwards, and Toshiba's English label 'TOSHIBA' also became 'TOSHLBA', and the difference in a letter is difficult for ordinary people to identify, achieving the effect of a copycat fishing in troubled waters.

Speaking of which, this is obviously an act of deceiving consumers, which is similar to the fake 'Kang Shuaifu' aspect and 'Wang Laoxing' herbal tea in later generations.

But now in this year, the country's protection of trademark property rights is not high, and the identification rate of ordinary consumers for counterfeit goods is not high, Duan Yun playing this kind of 'edge ball' is actually a kind of helplessness, although it is said that there is a suspicion of counterfeiting, but in fact, the antenna products made by Duan Yun are actually quite advanced, after all, it is something he researched on the university campus in his later life, and the technology is at least ten years ahead.

Considering that the waste plastics he collected now may be poor in insulation and high temperature resistance, Duan Yun designed the mold to be very thick this time, and added a few lines of English letters to it, making it look much higher in appearance and grade.

The design drawings of the mold were revised several times, and it was not until 5 o'clock in the afternoon that the announcement of the factory leaving work sounded, and Duan Yun finally designed several plans that satisfied him.

Duan Yun plans to find the help of the master in the mold workshop during the night shift tonight, and it is estimated that Yun will be able to get the mold of the injection molding machine in a day or two.

As for the high-temperature insulated electrical shell plastic, Duan Yun has to find a way to buy it through other channels, and this has to be done step by step......

......

After work, Cheng Qingyan sat on a Phoenix bicycle and rode slowly on the boulevard of the factory street.

At this time, there was also a book on "Foreign Metal Heat Treatment Technology" that had just been borrowed from the library in her basket, and there was a delicate bookmark in the middle of the secretary.

Now that the factory wants to organize a technical improvement competition, Cheng Qingyan has already learned about it, but Cheng Qingyan has not shown much enthusiasm for it.

Compared with her peers, Cheng Qingyan's mind is relatively mature, she is obsessed with technical things, but she is not eager for quick success, and she is rarely affected by the external environment and things.

In her opinion, the factory's emphasis on technological improvement work and Zhao Dongsheng's vigorous implementation of the "Rationalization Suggestions and Technical Improvement Reward Regulations" is undoubtedly a great encouragement for people like them, and it is indeed a good thing, but Cheng Qingyan also believes that any technological upgrading and improvement has a gradual process, and in the short term, it is a matter of quick success and quick profit, which is out of the law of scientific and technological development.

"Qingyan!"

Just as Cheng Qingyan rode to the living area, a woman's voice came from behind.

"Xiaolan. When Cheng Qingyan turned her head and saw that the woman riding a bicycle behind her was Yu Shulan, she greeted with a smile.

"Come out at night, the factory is holding a ballroom dance party in the air-raid shelter tonight, I just don't have a dance partner, can you go play with me at night?" Yu Shulan said with a little excitement on her face after coming to Cheng Qingyan's side.

"No, I don't know how to ballroom dance. Cheng Qingyan said.

"I can teach you, it's easy to learn. Yu Shulan grabbed Cheng Qingyan's arm and said.
