Walking on the road, I also thought a lot about various problems, especially about the results of the trial production of the light transmission factory at this time: plane lenses.

The plane lens cannot magnify or reduce the image of the object, and such a lens can only do a simple lens protection function on the camera lens, that is, the UV lens, and it is also a UV lens that cannot filter ultraviolet rays.

But then again, with the current level of technology, it is already very good that lenses can do this, at least Wang Zhengguo can have some different ideas. In many cases, glasses are not necessarily myopia and presbyopia, they may also be flat and translucent sunglasses.

It can be said that if Wang Zhengguo plans to make sunglasses now, he only needs to wait for the laboratory to solve the problem of superhard coating, and then he can use the equipment of the light transmission factory to carry out large-scale production.

This is naturally another technical problem, Wang Zhengguo knows a little about this, in fact, it is nothing more than adding various chemical elements, which can be a chemical element material such as a pyrospiron, of course, you can also choose to directly dye the finished lens, the lenses that come out of this way do not have the function of filtering ultraviolet rays, and can only be regarded as the category of sunglasses, but if you want to use it to pretend to be forced, it is excellent!

That's right, now Wang Zhengguo has a bold idea, he can use the funds in his hand to purchase a batch of lenses produced by the light transmission factory, and then find the corresponding unit to dye the lenses, and finally use the high hard coating technology in the laboratory, which can get cheap finished sunglasses lenses.

After having lenses, it is almost the biggest trouble to make glasses, and then you only need to make the frames again, and there is really no technical content in the other, it is nothing more than the proficiency of the workers in the process of making glasses.

In China, in 80 years, although the sci-fi film "The Man from the Bottom of the Atlantic" introduced by CCAV has been released for a long time, its influence and popularity are still undiminished, especially the "toad mirror" with the fire of the show, which was not produced at all in China, and could only be obtained from the southern port in the form of parallel imports.

In these years, the toad mirror is a necessary thing for fashionable youth, and it is a symbol of avant-garde and fashion, at least Wang Zhengguo has seen people wearing this thing sporadically on the streets of Shudu, and the return rate is no different from driving a luxury sports car on the street of Shudu in 2000.

The price of parallel toad mirrors remains high, on the one hand, it is rare and expensive, on the other hand, genuine toad mirrors are not necessities of life abroad, and they are more of a light luxury taste, plus genuine toad mirrors must also have the function of filtering ultraviolet rays, and their manufacturing costs are still relatively high.

In this case, the lens made of PMMA resin, using a relatively simple dyeing process, coupled with a high-hardness film, such a product is almost not much different from the toad mirror from the appearance, but it is very different from the toad lens made at a high cost abroad.

Anyway, it's pretending to be used, and the most domestic trendy young people have seen it on TV, even if they know what the toad mirror looks like, and what kind of effect it has after wearing it, none of them know, in fact, they just need to look like it.

For this kind of low-demand market, Wang Zhengguo plans to copy this thing, not to mention that it is as expensive as foreign countries, but it is simply appropriate to ask for a two-thirds price, which is simply a huge profit.

.....

All aspects of the plan are highly feasible, 8,000 yuan as a start-up capital is almost enough, now wait for when the laboratory can get the coating technology done, otherwise Wang Zhengguo really dare not let go.

As for how to assemble the lenses into the glasses frame and ensure the quality of the glasses, Wang Zhengguo, who has never had relevant experience, has his own way: poaching people!

Just when the last time the imperial capital academician was at home, Zhang Huitao said that Shudu's lean glasses sounded like a time-honored brand, and the lens assembly technology must be excellent.

Moreover, this toad mirror project does not need to be shared with the laboratory, it can be an OEM project paid by Wang Zhengguo himself, and at most the laboratory will be given a fee for the use of high hard coating technology, which means that a huge amount of money will be exclusive to Wang Zhengguo, based on the windfall profits of this model, it is not a problem to double 8,000 yuan into 80,000 yuan.

With the follow-up fund of 80,000 yuan, whether it is to continue to invest in the toad mirror project, or to invest in the construction of a regular factory, it seems that it can be regarded as having a certain foundation and confidence, and the follow-up investment can be quickly opened.

The more I think about it, the more reliable it becomes, perhaps we should urge the laboratory to solve the problem of lens hardness and surface wear resistance as soon as possible, which has become the most critical technical link now.

To make a concave lens of PMMA material, not only need to solve the hardness problem, but also need to consider in the grinding, the problems encountered in the grinding of PMMA with soft material and ultra-high hardness silicate glass must be very different, which requires follow-up investment of more money and time, Wang Zhengguo has not been able to wait so long, and now it is better to start with a more mature toad mirror.

Production specifications, venues, workers, and sales channels can all be cultivated by the toad lens project first, and the myopia glasses project that can be trickled down in the future should strive for excellence, and it is best to get off to a good start.

.....

It's late, there's no need to go back to school, go back to the family area of Shudu in a leisurely manner, make some food casually, and only remember a question when lying in bed, it seems that it has been a long time since I have contacted the object of the demon capital, whether it is for my parents to ask an explanation, or to find some fun for my boring life, this is very necessary.

So on a whim, I got up from the bed again, took out the letterhead, sat down at the desk, thought about it, smiled, and began to make sentences.

Dear Ocean,

The last time I was contacted, after my calculations, it was three months ago, a total of 98 days, I know, before that, because of the time of our contact gradually decreased, after non-destructive testing, only to find out that it was my love for you that ran poorly,

After the fault diagnosis, the test report pointed out that the original 45 steel material needed to be changed to 40Cr, oh my! I can't imagine that my heart will have to be rough, forged, welded, and polished after melting, just like I miss you at 1000°.

I want to turn myself into a precision machine, ultra-high surface roughness, perfect tolerance fit, I want to strictly calculate the performance diagram and calculation of my love for you, after listing the table, choose the multi-stage compression method, only efficient can express my deep love for you.

After calculating a series of touching, sweet, warm, intimate, and gentle indexes, after summarizing the above, I finally determined the basic design structure of my loyalty to you, selected the appropriate part structure according to the national standard, and then drew a CAD drawing for imaging.

....

As a veteran of the love field, Wang Zhengguo is also the right medicine, there is no way, what he learned in Fudan is mechanical, and only in this way can it have a miraculous effect, so as to maintain this crumbling relationship.
