Chapter 119 The First Plastic Case

For the next two days, Duan Yun passed peacefully.

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 a serious demerit. The one-and-a-half-year observation period made Cui Linleizi and the others feel a little hopeless, which meant that they would not be able to get a salary increase and compensation for more than a year in the future. Evaluation of various other welfare activities.

Moreover, this kind of punishment must be recorded in the employee's personal file. If it is not done well, it may not be able to be rated as a model worker or promoted for a lifetime.

Although Cui Linleizi's performance in the factory is usually mediocre, and they don't have any hope of becoming a model worker or being promoted, but in any case, there was still such hope in the past, but now, there is almost no possibility...

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

From Cui Lin and Lei Zi's point of view, Duan Yun has technology, vision and brains, and these days Duan Yun earns more here than at the factory in a month, so Cui Lin and Lei Zi are very fond of Duan Yun now. Congratulations, when facing Duan Yun, he was even more obedient than when facing the factory leader.

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

In the past two days, in addition to the daily business of installing antennas, Duan Yun also started his injection molding machine experiment.

Last night, Duan Yun approached Qian Deqiang who was in the welding rod business at Electric Construction No. [-] Company.

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

What surprised Duan Yun was that the list of waste materials was more than 20 pages long, and this was not all. It included materials discarded during engineering installation, such as waste copper and aluminum wires, equipment packing boxes, waste materials from cutting workpieces, and various waste materials. Welding rod head waste, etc.

But Duan Yun also knew that these scraps were Qian Deqiang's 'cake' and he couldn't move them, and he had no interest in these things.

The only thing Duan Yun is interested in is that some of the plastic packaging waste is very good PE material, but Duan Yun can't buy too many at present.

In addition to these waste materials, there are also various equipment replaced by Power Construction during the installation and maintenance of the power plant, including scrapped motors, obsolete old equipment, etc. There are so many types that Duan Yun is dizzy.

Today, the Daxing No. [-] Power Plant factory undertaken by Power Construction is a project of up to [-] million yuan. In addition, it also undertakes the equipment maintenance of the No. [-] 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. Even some cheap equipment is far from the end of its life, and it feels troublesome to repair, so it is simply scrapped.

He learned from him that there is a discarded welding rod baking machine in the warehouse of the Electric Construction Materials Department. The heater inside can no longer be used, but the electronic temperature controller on it can be used. Qian Deqiang ordered one.

Although their first business was not big, and 20 yuan was not a lot of money to Qian Deqiang, it was a good start, and after Qian Deqiang learned that Duan Yun was in the electrical repair and antenna business, he also agreed. Feeling that Duan Yun is a good potential client, the two of them talked happily all night and drank two bottles of [-]-degree sorghum white.

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

This made Duan Yun very happy, because during the night shift last night, Duan Yun had already got the molds made by other workshop masters, which meant that Duan Yun could start processing the plastic casing of the antenna today.

Making an antenna amplifier casing is certainly not worth Duan Yun's trouble. The key is that once Duan Yun masters the technology of making plastic casings, it will be a very important step for him to produce other electronic products in the future. After all, almost all electrical appliances The equipment needs to have a plastic shell with good performance and high insulation.

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

It took Duan Yun a whole afternoon to install a simple temperature control system on the injection molding machine, and also installed the steel mold that had just been processed.

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

As for the temperature control of plastic heating, generally the better the performance of the plastic raw material, the stricter the temperature control, otherwise the performance of the plastic product will be greatly reduced, but Duan Yun's antenna amplifier casing does not have such high requirements, it only needs to be able to protect The internal circuit board is enough, so the temperature is directly set at [-] degrees Celsius.

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

After adding the chopped and washed waste plastic particles into the funnel of the injection molding machine, Duan Yun started to power on and heat up.

As soon as the temperature went up, a pungent smell wafted from the slot.

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

Without an electric fan ventilation system, Duan Yun could only use drafts to dissipate the poisonous gas. In addition, Duan Yun planned to buy some masks to prevent people from being poisoned.

After a while, Duan Yun asked Cao Dong to press the lever to press the melted plastic in the piston into the mould, after seeing that the electronic thermometer had reached [-] degrees Celsius.

However, Cao Dong's small body seemed to be struggling to press the lever, so Duan Yun simply went into battle himself.

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

After a while, after feeling that the mold had cooled down, Duan Yun opened the screw that fixed the mold, knocked it on the ground, and a formed plastic shell fell off from it.

"Brother, it looks okay." Cao Dong didn't care about the hot plastic case that just came out, picked it up and glanced at it, and said pleasantly.

"Let's make do with it." Duan Yun took a look, then curled his lips and said.

It seems that the precision of the mold processing is not high, and the pressure of Duan Yun's injection molding is almost low, so the newly made shell is slightly rough, and there is still a gap between the delicate plastic products of later generations.

But in any case, the casing used as an antenna amplifier is definitely enough, and the raised traditional Chinese characters of "Zhidong" and the fake trademark of "Toshlba" in English are very clear and eye-catching...
