"You can collect more or less this plastic. Duan Yun picked up the plastic shell of a worn-out thermos and asked Lao Zhangtou.

"Two cents and two pounds. Lao Zhangtou paused, and then said: "But I really can't sell ......."

"I pay three cents a pound for this hard plastic. Duan Yun stretched out three fingers.

"This ......" Hearing Duan Yun's offer, Lao Zhangtou's eyes suddenly lit up.

"I came in the middle of the night to pick up the goods. Cao Dong on the side said.

"Done!"

Lao Zhangtou gritted his teeth and said.

There weren't many of this kind of hard plastic, and it didn't hurt to sell it to Duan Yun privately, and the price Duan Yun gave him was indeed not low.

"Then it's decided. Duan Yun nodded with satisfaction when he heard this, and then after chatting with Lao Zhangtou for a few words, he led Cao Dong out of the scrap station.

"Brother, do you want such a little plastic?" Cao Dong asked after following Duan Yun out of the scrap yard.

"He collects a lot of plastic here, but most of it can't be used. Duan Yun frowned slightly, and asked Cao Dong, "Do you know which scrap yard is around here?"

"This is the only one in our factory, but I also know a lot of the caretakers of the scrap yards in the surrounding factories...... Or, I'll take you to another house?" Cao Dong said.

In the past, Cao Dong relied on stealing scrap iron to eat, so he knew the scrap station within a radius of more than ten miles in the factory area, and he was very familiar with the management.

"Not for now. Duan Yun shook his head, and then said, "I was going to do an experiment on the little bit of plastic I bought here today. ”

"Do experiments?" Cao Dong was stunned when he heard this.

"I want to make a plastic shell for our products, and if it is successful, you will have to help me contact a few more scrap stations, and we may have to produce them in large quantities in the future." Duan Yun said.

"But how can this waste plastic be processed into a shell?" Cao Dong asked curiously.

"Actually, it's very simple, just make an injection molding machine, and I'll go back and design it. Duan Yun said.

"Well, that's okay, as long as Brother Duan you are in need, I will help you contact a few more scrap stations when I go back. ”

"Hmm. Duan Yun nodded with satisfaction when he heard this.

After riding back to the rental house, Duan Yun put the car away and walked into his studio.

For Duan Yun, the injection molding machine is actually not a complicated piece of equipment.

Generally, plastic factories have desktop injection molding machines, and the production efficiency is very fast, but a small workshop like Duan Yun does not need such a large output, so it is completely enough to make a manual injection molding machine.

In principle, the injection molding machine is to heat the scrap of the plastic semi-finished product to soften, and then inject it into the mold, and after the mold is cooled, you can get a plastic finished product.

In his previous life, Duan Yun also saw a foreign handicraft enthusiast on the Internet DIY a simple manual injection molding machine, the structure is very simple, that is, make a funnel-shaped feeding trough with iron sheets, and then tie several heated coils to a steel pipe. After the plastic is heated and softened, you only need to press down the lever above, and the heated and softened plastic in the steel pipe will be directly pressed into the mold, and the operation is very simple.

The only problem is that Duan Yun can't find an electronic thermometer to measure the heating temperature now, but this is not a big problem, in Duan Yun's opinion, he only needs to test a few more times, and after mastering the time of coil heating, practice makes perfect, and it is not a big problem to process a qualified shell.

Sitting in front of the workbench, Duan Yun took out paper and pen and quickly began to draw design drawings.

At about six o'clock in the evening, Duan Yun's drawings had been basically designed, and he felt a little hungry, so he walked out of the studio at any time, felt a cigarette and smoked it outside.

In the afternoon, Cui Lin Leizi led the three new young workers who had already returned from their work outside, and several people were talking and laughing, obviously the afternoon work was very pleasant.

I didn't work at night, and Cao Dong, including Cao Dong, had already begun to assemble the antenna rack in the next workshop.

The shipments are okay these days, so according to Duan Yun's requirements, they must keep the antennas in sufficient stock, so a few people plan to make a few more antenna mounts tonight.

Although Cao Dong and Cui Lin are already skilled in assembling antennas, Duan Yun still strictly controls the quality of finished products.

The length and spacing of the antenna frame must be accurate, because a little deviation will lead to a great reduction in the effect of the antenna receiving TV signals.

In addition, after the antenna shelf is assembled, it must be polished and bright, and then evenly brushed with a layer of anti-rust paint to make the finished product look more beautiful, which is also very important for users to improve their good impression of the product.

"Brother. ”

A pretty figure walked in the distance, and Duan Fang had already come over to deliver food to his brother.

During this time, Duan Yun's food has always been in charge of her sister Duan Fang, and after she gets home from school in the afternoon, she will make a few hot dishes and steam a basket of steamed buns, and send them to Duan Yun at about six o'clock.

And Duan Yun naturally couldn't lose his family, so he decided to give the family dozens of yuan more living expenses every month, that is, the money earned from selling an antenna, to solve the dinner expenses of himself and Cao Dong and others.

In addition, Duan Yun also felt sorry for his sister, and often stuffed her with some pocket money, which can be regarded as a kind of compensation.

"My sister has worked hard. Duan Yun said with a smile after receiving a basket full of vegetables and rice from Duan Fang's hand.

"It's hard work, it's all a family, it should be. Duan Yun pursed his lips and smiled, turned his head to look at the studio behind Duan Yun, and said in surprise: "Brother, your house looks so beautiful, this table is all new, right?"

"Hmm. Duan Yun nodded, and then said, "I'll find someone to make you a new desk when I go back." ”

"Forget it, we don't have a place to put the table in our house. Duan Fang pouted and said.

"That's okay, when my brother divides the new house in the future, there will be a place for the writing desk. Duan Yun said with a smile.

"Divide the room?" Duan Fang's eyes lit up when he heard this, but then he pouted and said: "There are so many families in our factory waiting for the division of the house, you have just entered the factory, how to say it, you have to wait for several years." ”

"You don't have to worry about this, as soon as this year, at the latest next year, my brother will definitely let you and our mother live in a new house!" Duan Yun raised his eyebrows and said.

"Bragging!" Duan Fang grimaced at his brother, and then said, "Okay, let's eat quickly, the dishes are almost cold." ”

"It's time for dinner. At this time, Cao Dong and Cui Lin also poked their heads out of the rental house next to them and asked with a smile.

"Alright, you can go back to dinner with our mother. Seeing this, Duan Yun motioned for Duan Fang to leave.

"Yes. After Duan Fang answered, he left with two pigtails.
