"In the future, I hope you can give me more guidance in terms of learning. Duan Yun said with a smile.

"Yes, I'm going to sort out a list of the key content of the exam first, and I'll bring it to you next time I go to class, and you can go back and work harder after you copy it." Cheng Qingyan said very generously.

"Thank you. Duan Yun thanked him when he heard this.

Duan Yun was still a little moved by Cheng Qingyan helping him so much, but Duan Yun also thought more about other aspects, he just felt that this Cheng Qingyan was not pretentious or pretentious compared to ordinary girls, and she was indeed very easy to get along with.

After sending Cheng Qingyan home, Duan Yun was also ready to go to the night shift as always.

......

The next morning, Duan Yun went to the workshop of the Ma military camp and took a turn, and found that Xu Fugui's village-run enterprise had initially had production capacity, and the original row of seven or eight dilapidated caves had been renovated, and the courtyard was basically the same as the layout of Duan Yun's workshop, and an open-air shed was built, and the equipment mold had just been moved out of the cave and placed in the courtyard.

However, their method of producing plastic products is different from Duan Yun's.

Xu Fugui has been planning and preparing this village-run plastic factory for a long time, and he has also gone to other places to learn from experience, in addition to the molds provided by Duan Yun, he also bought some plastic processing equipment from other places.

The operating principle of these equipment is also very simple, that is, the purchased waste plastic is heated and melted, squeezed into noodles, then cooled by cold water, cut into granules, and finally these plastic particles of different colors are used to make plastic products such as basins and buckets through the injection molding machines and molds provided by Duan Yun.

Under normal circumstances, it is in the range of 180 to 220 degrees, and the temperature is too high to cause discoloration and performance degradation of plastics, so it can only be controlled by electric heating.

But Xu Fugui's plastic processing plant is used in the purchase of inferior materials, the more inferior the plastic to the temperature accuracy requirements are lower, the temperature up and down dozens of degrees does not matter, in the end can be squeezed together by high pressure, and Xu Fuguo does not have a special temperature control system, workers rely on experience, generally after a few days, you can make qualified plastic products.

In addition, Xu Fugui will never use electricity to heat the plastic like Duan Yun, Daxing is the coal capital, and the coal is very, very cheap, so the plastic heating is also used with coal, and the cost has been reduced a lot.

"Xiao Duan, take a look at the washbasin produced in our factory. At this time, Xu Fugui walked to Duan Yun with a smile with a green basin.

"Uh. Duan Yun was stunned for a moment, took the basin and shook it, and said, "Isn't it thick......

"I started to want to make it thinner, but the quality of the plastic was not good, so I made it a little thicker. Xu Fugui smiled, and then said: "The people in the village don't have too high requirements for this thing, as long as the price is cheap and durable, at least it can't be broken, that's it." ”

"Look at the look of it. Duan Yun nodded when he heard this, and after slamming the basin to the ground, he saw that after the basin bounced up, it rolled to the side intact, and praised: "Not bad!"

"Recently, I've been training workers, and I haven't made many things, and I guess it will take a few months to increase the output. Xu Fugui paused, and then said: "In addition, I contacted several rural supply and marketing cooperatives in the surrounding areas according to the method you taught me, and they all agreed to sell our products on behalf of us, or your method works......

"Hehe, doing business is a win-win situation, if there is money to be made, there must be people who are willing to cooperate. As Duan Yun spoke, he took out a note from his pocket, handed it to Xu Fugui and said, "Secretary Xu, you can help me buy something when I go back, and the product name is written on it." ”

"It's easy to say!" Xu Fugui nodded again and again when he heard this, took the note and glanced at it, and read: "PP polypropylene, one hundred kilograms...... Is there only so little?"

"I need to try to make some products out to do market research in the early stage, and I will buy a large number of them after finalization, so I don't need to buy so much for the first time. Duan Yun said.

Duan Yun helped Xu Fugui establish this village-run plastic processing factory, in addition to secretly occupying a part of the shares, the most important thing is to buy regular high-quality plastic semi-finished products produced by the big factory through the formal channels of Xu Fugui, a village-run enterprise.

In the early stage, Duan Yun plans to use these plastics to make the shell of the speaker first, and if the sales are good, the next step will be to increase investment in small batch production.

The reason why Duan Yun chose to use plastic speakers is that he wants to match the product grade with the wooden speakers he made before, and enrich the product sales channels.

The material of the cabinet affects the performance of the speaker, the greater the material density of the speaker shell, the smaller the vibration generated by the cabinet when the sound is emitted, especially the active speaker with a high-power amplifier, the sound can be restored more realistically.

Wood is much denser than plastic, so wooden speakers work better than plastic speakers.

At present, the wooden speakers made by Duan Yun are undoubtedly top-level speakers, but the price of up to 600 yuan is definitely not what ordinary families can consume, and at present, Duan Yun only has a master well and two small apprentices, and the finished speakers processed every month are limited, so at present, they can only take the high-end customized sales route.

The plastic PP shell is widely popular in high-end speakers in later generations, with good consistency and low distortion, and the performance in all aspects is remarkable, the most important point is that mass production is more convenient and the cost is low, so the price is more 'close to the people', which is the real product that can be mass-produced.

In Duan Yun's view, if the price of this plastic speaker is reasonable and the quality can be strictly controlled, it will definitely replace the TV antenna in the future and become another hot-selling product in his workshop.

"That's okay, I'll arrange for someone to help you go to Factory 3528 to buy goods when I turn around. Xu Fugui said after putting away the note.

"Okay, go back and give me the invoice, and I'll reimburse you. Duan Yun responded.

Subsequently, after the two inspected the plastic workshop, Duan Yun rode away.

After having dinner at home at noon, Duan Yun returned to the studio of the rental house and began to design the shell of the new plastic speaker.

Duan Yun's plan is to first design seven or eight subwoofers with different shapes and low-end functional configurations, and then conduct door-to-door sales through his own customer channels through the antenna after-sales service, and finally select the most popular plastic shell subwoofer product for small batch production and sales through consumer feedback.

Limited to the current environment, as well as his own capital and manpower, Duan Yun can't expand the scale of production too much for the time being, and can only sell through a small range of sales similar to pyramid schemes.

But if Duan Yun wants to grow his business bigger in the future, he must definitely find another way to develop......
