Is it used to process items?

This is very convenient, whether it is steel or something else, if you want to make a shape, carve a mold in advance, and then soften the item in a vacuum, and then buckle it directly into the mold, so that it can be directly formed, and when it hardens in the air environment, you will get the item you want.

In this way, any complex parts, as long as the mold can be made, it is not a problem.

Li Shan has been working in the factory for a while, and has a certain understanding of the processing and manufacturing of aero engine parts, and the processing of these parts requires some very advanced processing equipment, so as to ensure its processing quality, which is also a reason for the high cost of aviation manufacturing.

Many people in the factory have opened factories outside, although everyone is shaking their heads and sighing when they talk about their factories, but they still can't stop them from driving luxury cars and entering and exiting high-end hotels, which shows that there must be money to be made here!

Why can't you open a factory like this and use this method to process those complex aerospace parts?

Generally, this method of molding with molds is mostly suitable for those materials that are plastically deformed, such as plastics, etc., and for metal materials, it belongs to the category of casting processing.

Casting is a kind of metal thermal processing technology that has been mastered by human beings for about 6,000 years. The Huaxia Kingdom has entered the heyday of bronze castings between 1700 ~ 1000 BC, and the craftsmanship has reached a very high level.

However, metal casting also needs to take into account many problems, heat dissipation performance and thermal deformation, mechanical properties are not as good as forgings, workers' labor intensity is large, quality is unstable, the influencing factors are complex, and many defects are easy to occur.

Now you obviously don't have to think so much about this processing method, you only need to make a mold in advance, and you can use it to process any product. Compared with the expensive high-precision processing equipment to process parts, the cost is obviously much lower, which can ensure the quality of processing, and the cost is much lower.

Of course, this can not only process some metal parts, but also any other items such as glass, stone, etc. Only the unthinkable, nothing can't be done!

Li Shan feels that this is a sustainable way to make money. Maybe it won't take a few years for him to easily earn millions, tens of millions, or even hundreds of millions of dollars, and the more he thinks about it, the more excited he becomes.

After tossing and turning like this for a long time, I actually had some insomnia, and in this case, I can't calm down on anyone.

When the excitement in his mind gradually receded like a tide, Li Shan began to calm down. Despite his young age, his many experiences of coming through various adversities have taught him that one cannot get carried away under any circumstances!

If his factory is put into operation, how will the competitors who have been robbed of his business give up?

Why can he process such a low-cost item, so that it will attract the attention of some people with a heart, and his secret will eventually be completely exposed, this unique processing method in this world will definitely cause others to blush, in the face of huge interests, people's greed has no bottom line.

At that time, I am afraid that I will have money to earn, and I may not have the life to spend it.

After thinking about it for a long time, I felt that this could indeed have a very terrible consequence, and I had nothing to do about it at the moment.

Seeing that it can generate huge benefits but cannot be implemented, Li Shan can't help but be a little crazy, relative to life, he can't do this for the time being without thinking of a safe method.

When he got up the next day, Li Shan's eyes were a little swollen, obviously he didn't sleep well all night, he packed up the items that were left outside and didn't clean up, and prepared to go to work.

When he picked up the iron rod and the stone, he felt that something was wrong, and these two things obviously became much lighter, but Li Shan couldn't be sure for a while.

At first, he didn't notice this when he put these items in the vacuum bag, but now he feels a little light, is it just an illusion.

So, Li Shan decided to try again, he weighed those items with the electronic scale at home, recorded them, and put them all into a vacuum bag, and waited a few days to see the effect.

After a few more days, Li Shan couldn't wait to open the vacuum bag to see if the weight of the two items had changed.

When he got the scale, as Li Shan expected, the weight of the iron rod and the stone became lighter!

Although the weight becomes less noticeable, it is enough to justify the fact that the weight can be reduced.

After a few more hours, the two items began to harden, and Li Shan measured their weight again, and nothing changed.

Although they are still a little elastic to the touch and have not yet become as hard as before, Li Shan is sure that these two items, like the "coal block", will eventually become extremely hard, but their weight will remain in their current state.

In addition, Li Shan also found that these items had obviously become much smaller, especially the stone, which used to be the size of an egg, but now it was only the size of a walnut.

So, Li Shan made a bold speculation that the "coal" was actually coal, but due to some accidental factor, it was enclosed in a certain vacuum environment with the jade, and this vacuum environment was likely to be underground.

The long-term vacuum environment makes the coal so light, yet so hard, that the iron rod and the stone will become harder over time. I just don't know how big that coal was originally.

Through this series of experiments, Li Shan roughly came to the following conclusions:

First of all, in a vacuum, any item will soften under the action of jade, and when it is re-placed in a normal air environment, it will become harder, although further verification is carried out, but from the state of the coal, it can be inferred that this hardness and strength will be stronger than the original.

Secondly, in a vacuum, the item will gradually become lighter, and its weight will remain in this lighter state even in a normal air environment.

Third, the volume will shrink, as for the extent of the reduction, it is related to the length of time in the vacuum environment, the longer the vacuum time, the more obvious the volume reduction.

The above points are summarized by Li Shan through continuous experimentation and analysis, and the existence of these functions is obviously beyond the scope of knowledge that Li Shan can understand.

He didn't dare to consult anyone, and he couldn't even ask netizens questions on some websites, but could only look up some relevant information on the Internet by himself, and of course found nothing.

These things are obviously a kind of extraordinary existence, how can they give full play to their maximum function, Li Shan thought about it and didn't come up with any useful methods.
