Chapter 94 Injection Molding Machine

"How much do you collect this kind of plastic?" Duan Yun asked Lao Zhangtou, picking up the plastic shell of an old thermos bottle.

"Twenty cents and a pound." Lao Zhang paused, then said, "But I really can't sell it..."

"I accept this kind of hard plastic for thirty cents a pound." Duan Yun stretched out three fingers.

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

"I came over in the middle of the night to get the goods." Cao Dong said.

"to make!"

The old man gritted his teeth and said.

There is not much of this kind of hard plastic, so it doesn't hurt to sell it to Duan Yun privately, and the price Duan Yun gave him is indeed not low.

"Then it's settled." Duan Yun nodded with satisfaction, and after chatting with Lao Zhangtou for a while, he led Cao Dong away from the junkyard.

"Brother, do you need so much plastic?" Cao Dong asked after following Duan Yun out of the waste station.

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

"This is the only one in our factory, but I know quite a few administrators of the waste stations in the surrounding factories... Or, may I take you to another house?" Cao Dong said.

In the past, Cao Dong used to steal scrap iron to make a living, so he knew the scrap stations around ten kilometers away from the factory, and he was very familiar with management.

"No need for now." Duan Yun shook his head and continued, "I intend to experiment with the plastic I bought here today."

"Doing an experiment?" Cao Dong was taken aback when he heard the words.

"I want to make a plastic casing for our product. If it is successful, you need to help me contact a few more waste stations. We may have mass production in the future." Duan Yun said.

"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. I'll design it when I go back." Duan Yun said.

"Uh, that's fine, as long as Brother Duan is in need, I'll help you contact a few more waste stations when I turn around."

"Yeah." Duan Yun nodded with satisfaction.

After riding the car 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 a manual injection molding machine is enough.

In principle, the injection molding machine heats and softens the scrap of plastic semi-finished products, and then injects them into the mold. After the mold is cooled, a finished plastic product can be obtained.

In his previous life, Duan Yun also saw on the Internet a simple handmade injection molding machine made by a foreign craftsman himself. Tie on a few heated coils.Above the steel pipe is a piston lever similar to a pump, and below it is the bracket and the mold. After the plastic is heated and softened, you only need to press down the upper lever, and the heated and softened plastic in the steel pipe will be directly pressed into the mold, which is very easy to operate. Simple.

The only problem is that Duan Yun can't find an electronic thermometer to measure the heating temperature, but this is not a big problem. In Duan Yun's opinion, it only takes a few more tests. After mastering the heating time of the coil, practice makes perfect and processing. It's not a big problem to come out with a qualified casing.

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

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

In the afternoon, Cui Linleizi and three new young workers had returned from their work outside. Several people were chatting and laughing. Obviously, the afternoon work was very enjoyable.

At night, including Cao Dong, he has already started to assemble the antenna rack in the workshop next to him.

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

Although Cao Dong, Cui Lin and the others are already proficient in assembling antennas, Duan Yun still carries out strict quality control on the finished products.

The length and spacing of the antenna stand must be accurate, because a little deviation will greatly reduce the effect of the antenna receiving TV signals.

In addition, after the antenna rack is assembled, it must be polished brightly, and then evenly painted 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 goodwill towards the product.

"elder brother."

A pretty figure came from a distance, Duan Fang had already come to deliver meals to her brother.

During this period of time, Duan Fang's younger sister, Duan Fang, was in charge of the meals. After she went to school in the afternoon, she would make a few steamed steamed buns with hot dishes and deliver them to Duan Yun at around six o'clock. Come.

Of course, Duan Yun couldn't have lost his family, so he decided to give his family dozens of yuan more for living expenses every month, that is, the money earned from selling an antenna, to pay for dinner expenses for himself and Cao Dong and others.

In addition, Duan Yun also felt sorry for his sister, and often gave her some pocket money, which was considered a kind of compensation.

"You've worked hard, girl." Duan Yun said with a smile after taking a basket full of vegetables from Duan Fang.

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

"Yeah." Duan Yun nodded and continued, "I'll find someone to make a new writing desk for you."

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

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

"Separation?" Duan Fang's eyes lit up when she heard the words, but then she pouted and said: "There are so many families in our factory waiting for the house to be divided, you have just entered the factory, so you have to wait for several years. Just do it."

"You don't have to worry about this. This year at the earliest, and next year at the latest, brother will let you and our mother live in a new house!" Duan Yun said with a raised brow.

"Bragging!" Duan Fang grimaced at her brother and said, "Okay, let's eat quickly, the dishes are getting cold."

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

"Okay, go back and have dinner with our mother." Seeing this, Duan Yun motioned for Duan Fang to leave.

"En." After Duan Fang responded, she flung her two pigtails and left.
