In the next two days, Duan Yun was calm.

Cui Lin, Lei Zi and others have also returned to work normally, and they seem to be working harder than before.

This time, the factory gave them all a major demerit, and the year-and-a-half-long observation period made Cui Lin Leizi and his sisters feel a little hopeless, which means that they will not be able to get a salary increase and other welfare activities for more than a year in the future.

Moreover, this kind of punishment must be written into the personal file of the employee, and if it is not done well, it may not be possible to be rated as a model worker or promoted for the rest of his life.

Although Cui Lin Leizi usually performs average in the factory, and they don't have much hope of becoming a model worker or being promoted, in any case, there was still this hope before, but now, there is almost no possibility......

Working in the factory did not see any chance to change the fate of their lives, and Cui Lin and Lei Zi quickly shifted their hopes to Duan Yun's business.

In Cui Lin and Lei Zi's opinion, Duan Yun has technology, vision and brains, and he earns more from Duan Yun these days than he earns in a month in the factory, so Cui Lin and Lei Zi are also very respectful to Duan Yun now, and when facing Duan Yun, they are even more obedient than when facing the factory leaders.

In recent days, with more and more business, several people have made more and more money, which has undoubtedly boosted the morale of Duan Yun's team, and Duan Yun has a strong prestige and control in this team.

In the past two days, in addition to the daily installation of antennas, Duan Yun also began his injection molding machine experiments.

Last night, Duan Yun found Qian Deqiang, who was engaged in the welding electrode business at the first power construction company.

According to the previous agreement between the two, Qian Deqiang gave Duan Yun an inventory list of the power construction waste warehouse, which he obtained from the warehouse manager over there by virtue of his personal relationship.

What made Duan Yun smack his mind was that this list of scrap materials was more than 20 pages, and this was not all, including the raw materials discarded during the installation of the project, such as waste copper and aluminum wires, equipment packaging boxes, scrap materials from workpiece cutting, and various welding rod head waste slag.

However, Duan Yun also knew that these scraps were Qian Deqiang's 'cakes', and he couldn't move them, and he didn't have much interest in these things.

The only thing that made Duan Yun a little interested was some of the plastic packaging waste, which were all very good PE materials, but Duan Yun couldn't buy too much at the moment.

In addition to these scraps, there are also various types of equipment that have been replaced by power construction when installing and repairing the power plant, including scrapped motors, obsolete old equipment, etc., which make Duan Yun dizzy.

Today, the Daxing No. 2 Power Plant factory contracted by Power Construction is a project of up to 500 million yuan, and it also undertakes the equipment maintenance of a power plant all year round, so there are still a lot of old equipment and related components replaced in the waste warehouse.

In the past two years, the power plant has a lot of money, and the power construction side is also a big business, so it is not so careful to calculate, and even some cheap equipment is far from the end of the life, and it feels troublesome to repair, so it is simply scrapped.

I learned from him that there was a scrapped welding rod roaster in the warehouse of the Electric Power Construction Materials Department, and the heater in it was no longer usable, but the electronic temperature controller on it could be used, so he paid a high price of 20 yuan and booked one with Qian Deqiang.

Although the business between the two of them was not big for the first time, and twenty yuan was not a lot of money for Qian Deqiang, it was always a good start, and after Qian Deqiang learned that Duan Yun was in the electrical repair and antenna business, he also felt that Duan Yun was a good potential customer, so the two talked happily all night and drank two bottles of 60-degree sorghum white.

Qian Deqiang is indeed very reliable, and he is also very good at business, he sent the disassembled electronic thermostat to Duan Yun at noon today, and also gave Duan Yun half a bag of waste plastic shells containing stainless steel welding rods.

This made Duan Yun very happy, because during the night shift last night, Duan Yun had already obtained the molds that he had asked other workshop masters to make, which meant that Duan Yun would be able to start processing the antenna plastic shell today.

Of course, it is not worth Duan Yun's trouble to make an antenna amplifier shell, the key is that once Duan Yun has mastered the technology of making plastic shells, it will be a very important step for him to make and produce other electronic products in the future, after all, almost all electrical equipment needs to have plastic shells with good performance and high insulation.

Duan Yun now plans to make the plastic shell of the amplifier first, and then further improve the injection molding machine he made to make it so that it can make a better plastic shell for electrical appliances.

It took Duan Yun an afternoon to install a simple temperature control system on the injection molding machine, and also installed the freshly machined steel molds.

In the past two years, many small workshops processing plastic products in China have used cheap carbon heating water cooling, which is low cost and suitable for batch processing, but Duan Yun does not need such a large processing volume at present, and the cost of direct electric heating is completely acceptable.

As for the temperature control of plastic heating, the better the performance, the more strict the temperature control of the plastic raw materials, otherwise the performance of the plastic products made will be greatly discounted, but Duan Yun's antenna amplifier shell does not have such high requirements, only need to protect the internal circuit board, so the temperature is directly set at 200 degrees Celsius.

After everything was installed, Duan Yun, Cao Dong, Cui Lin and the others finished dinner first, and then began to conduct experiments in the small room.

After adding the shredded and washed waste plastic pellets to the funnel groove of the injection molding machine, Duan Yun began to power up and heat up.

As soon as the temperature went up, a pungent smell wafted out of the notch.

"Open all the doors and windows. Duan Yun said to Cao Dong.

Without an electric fan ventilation system, Duan Yun could only use the air to dissipate this toxic gas, and Duan Yun also planned to buy some masks to avoid poisoning.

After another moment, after seeing that the electronic thermometer showed that it had reached 200 degrees Celsius, Duan Yun asked Cao Dong to press the lever and press the dissolved plastic in the piston into the mold.

However, Cao Dong's small body seemed to be a little difficult to press, and Duan Yun simply went into battle in person.

Although Duan Yun also felt a little struggling, he finally succeeded in pressing the plastic into the mold.

After a while, after feeling the mold cool down a bit, Duan Yun opened the screws that fixed the mold and knocked it on the ground, and a molded plastic shell fell off from it.

"Brother, it's okay to look at. Cao Dong didn't care about the hot hands of the plastic shell that had just come out, so he picked it up and took a look at it, and said in surprise.

"Make do with it. Duan Yun glanced at it and said with a pout.

It seems that due to the low precision of the mold processing, and the pressure of Duan Yun injection molding is almost high, so the newly made shell is slightly rough, and there is still some gap with those exquisite plastic products in later generations.

But in any case, the shell used as an antenna amplifier is absolutely sufficient, and the raised traditional Chinese characters of '芝東' on it, as well as the copycat trademark of English 'toshlba', are very clear and eye-catching......
