Countercurrent 1982

Chapter 99
In the afternoon, Duan Yun continued to design his injection molding machine mold.

While drawing the mold drawings, Duan Yun was also considering other issues.

One of the biggest problems is the acquisition of Duanyun plastic raw materials.

The safety of electrical products is very important. Once there is an electric shock casualty, it will be a huge disaster for Duan Yun.

Although Cao Dong has now contacted several waste collection stations to buy several tens of kilograms of plastic materials per month, this kind of waste hard plastic purchased can only be used for the production of antenna amplifier boxes.

If Duan Yun wanted to make a small appliance like a household voltage regulator, he had to find a better plastic material.

After all, the voltage regulator itself is connected to strong electricity and has high requirements on insulation, heat resistance and hardness, so it must have a corresponding plastic casing.

In fact, Duan Yun decided to make a home transformer this time. On the one hand, he wanted to increase his income. On the other hand, he wanted to cross the river by feeling the stones, starting with small electrical appliances, and accumulating funds and technologies step by step. In the future, he will be able to make more complex and advanced products. of electrical products.

Although in terms of the current domestic policy trend, even if Duan Yun has enough funds, it is impossible to build a private factory, and the timing and preparations in all aspects are insufficient.

Although Duan Yun was a doctor of electrical and mechanical engineering in his previous life, he was only rich in theory. If he wanted to do more in the future, he must master the technology of actually producing products.

Although plastic casings are not considered high-tech to some laymen, if Duan Yun can master the technology and ability to produce such casings, it will be of great help to make other products in the future.

After all, whether it is a socket voltage regulator or an electric fan TV, a large amount of plastic will be used.

When it was after seven o'clock in the evening, Duan Yun locked the door of the studio and rode his bicycle to the night school.

At this time, many employees in the night school had already sat in the classroom early.

"Have you heard that No. 1 in the factory's technological improvement competition has a prize of 800 yuan, and can also nominate model workers..."

"A bonus of 800 yuan, my God, the factory has really invested a lot of money this time."

"Our factory is very profitable now. What is this money?"

At this time, several young workers sitting in the back row were discussing.

"Such a high bonus makes me a little excited. In fact, I have the ability to come up with some technological innovations. I just didn't want to be too showy before..." Song Guozhong also interjected at this time.

"Monitor Song, since you are so talented, you will definitely participate in this technical transformation competition, right?" A young worker with a split head next to him asked Song Guozhong with a smile.

"I've said it all, I don't like to be in the limelight. The ancients said: The mountains are not high, but the immortals are famous. The water is not deep, but the dragons are the spirits. This is a shabby house, but Wu Dexin... This ancient poem has a very artistic conception. Well, it also explains a truth, people do not need to deliberately show their abilities, and some people who seem to be capable on the surface may not actually have real abilities..." Song Guozhong turned his eyes to the vacant seat where Duan Yun was, and continued: "It's like a certain classmate in our class who became famous with the skills left by the retired master, and the bonus was recommended by the secretary to attend the night school. It seems to be very powerful, but this kind of person can also be popular for a while, time After a long time, it will be beaten to its original shape, as the so-called see him rise up a tall building, see him entertain guests and friends, and see that building collapse..."

"Haha, Squad Leader Song is indeed a discerning person,

"Old Song is so talented, it's so good to say that this building collapsed..."

A few young workers next to him said with a smile.

At this moment, Duan Yun had already strode into the classroom.

After everyone saw Duan Yun, they turned their heads to the side and stopped talking about him.

"Student Duan Yun, where is my pen?" As soon as Duan Yun sat down, Cheng Qingyan next to her turned her head and asked.

"Ah, look at my memory!" Duan Yun patted his head abruptly when he heard this, and said apologetically, "I'm so sorry, I forgot to bring it today."

After the last exam, Duan Yun came home and found that he was in a hurry to hand in the papers and forgot to return the pen to Cheng Qingyan.

Originally, Duan Yun brought the pen to his studio in the afternoon and planned to return it to Cheng Qingyan in the evening, but because he was too involved in drawing model drawings in the afternoon, he was thinking about technical matters all the time, so he left. I forgot to take the pen in the drawer with me.

"Then when can you return it to me?" Cheng Qingyan frowned slightly, obviously a little unhappy.

"Either way, let's go together at night, I'll go home and pick it up for you." Duan Yun said after thinking for a while.

"Okay." Cheng Qingyan nodded when she heard the words, and said, "That pen is a souvenir of my graduation, I must get it back."

"I'm really sorry." Duan Yun apologized repeatedly.

As soon as Duan Yun finished speaking, the math teacher walked into the classroom.

At this time, the math teacher was still holding a thick stack of papers in his arms, which were obviously the papers from the last exam.

"Be quiet. Before the lecture, I will hand out the test papers of our last exam." The students under the gate were already full, and the old teacher said, supporting his glasses with his hands.

"Zhang Qiang, 76 points."

The 80s college entrance examination paper has a full score of 76 points, only biology has a full score of [-] points, and a score of [-] in the math simulation test is considered an upper-middle score.

As soon as the math teacher finished speaking, a young man with a somewhat gentle appearance walked up to the podium to take the exam in the envious eyes of everyone.

"Han Wei, 64 points!"

"Guo Guiyi, 68 points."

The students whose names were called went to the podium every week to collect their exam papers.

"Cheng Qingyan, 93 points!"

When the math teacher read out Cheng Qingyan's grades, there was an envious whisper in the classroom.

There is no doubt that Cheng Qingyan's math score is quite high.

In fact, since Cheng Qingyan entered the night school, her grades in this class have always been top-notch, and she is also regarded by her classmates as the most promising student to be admitted to the night school this year.

"...Finally, I need to mention the test scores of two students. One is the highest score in this test, and the other student's score is not passing..." There were only two test papers left on the platform of the math teacher. At the time, he suddenly raised his head and said to the students under the stage.

As soon as the math teacher finished speaking, everyone turned their attention to Duan Yun and Song Guozhong, who had not yet received the exam papers.

"Amazing, Squad Leader Song."

"As expected of the number one talent in our class!"

Several students in the back row praised Song Guozhong.

It was obvious that Duan Yun only had a junior high school education, and he had just entered the staff night school for a short time. The one who failed the exam was undoubtedly him.

"Song Guozhong."

"coming!"

Hearing the teacher calling his name, Song Guozhong stood up, subconsciously shook off the shiny part of his head, straightened the collar of his tunic suit, and strode onto the podium.

The math teacher on the stage handed the test paper to Song Guozhong, looked up at him, and said lightly.

"Song Guozhong, this time you passed the grade by three points. You have to work harder in the future..."
