"Many foreign internal mixers use Farrell's screws, which can be used to continuously refine rubber compounds! From powder to film and then molding, it's almost a line of operation! We are still using a tipping bucket honey refining, and the rubber material produced cannot achieve continuity! ”

"There is also an adhesive, the foreigner side is basically DuPont, even if we buy the same number of adhesives as foreigners in China, it is also a simple match in China! To put it bluntly, foreigners don't want to put good things on our market, and we can't spend so much effort to import adhesives for such a small amount of products for you! ”

"Based on the above points, our products can only ensure one-third of the performance of foreigner products, that is, they can be used for one year, we can use it for four months at most, and I guarantee you three months! The price is much lower than that of foreigners, if you can accept it, then we will take it back to develop and do it, if you can't accept this quality, then you can find someone else! ”

"There are several big rubber factories in Gu'an, you can find them to cooperate! To be honest, according to my current level, I am far from catching up with foreigners! ”

Looking at the person in charge of the scene, his face was not good-looking, Ji Donglai did not hide it, nor did he brag, although Tan Xiumei made a strong look, Ji Donglai still went his own way.

The person in charge looked at the product over there, and then looked at Ji Donglai.

"Let's think about it again, after all, you were introduced by Mr. Tan, and we have news to inform you!"

I don't know what the other party thought, and finally stretched out her right hand to Ji Donglai and Tan Xiumei, Tan Xiumei was very helpless, it didn't matter if Ji Dong came.

"There's something wrong with you, I'm trying to hint at you that you can't see it?"

Out of the door, Tan Xiumei immediately switched from Chinese mode back to English mode, and came to Ji Dong for a while.

"You know, many people don't want to come to this opportunity, I'll give it to you, you might as well push it out! I knew I wouldn't bring you here, but there was news that they were going to cooperate with those rubber factories in Gu'an, do you know? They are supporting the country's military industry and locomotives, and they are very powerful! ”

"You tell people like that, I tell you, they won't cooperate with you 100%!"

Looking at Ji Donglai's indifferent appearance, Tan Xiumei's anger didn't come anywhere.

According to Tan Xiumei's understanding, to do business, you must praise the performance of the product, instead of Ji Donglai who explained it all at the first meeting, and now his efforts are in vain.

"Hehe, don't worry, I know those factories, and people won't pay attention to him! Moreover, the level of this small rubber factory in the market, especially the private enterprises, including those in Tianjin, is no different from me! It's a little bit of a difference, it's just a little bit of hair!"

"I said three months to leave room for maneuver for myself, but in fact I can use four months, there is no need to say it all, it's okay to surprise them! But if we say four months, three months and twenty-nine days are considered unqualified products! ”

"Those large state-owned rubber units are now busy with aerospace, locomotives and rockets, and someone will develop separate rubber and processes for him? Cut! Even if it is developed, can they afford it? I dare to say that if those rubber factories developed for him, it would definitely be more expensive than imported! ”

Thinking of the virtues of those rubber factories, Ji Donglai sneered in his heart.

Not to mention a chemical plant, it is the kind of large state-owned locomotive factory that requires these units to develop, if it is not sent by an official document, the other party will not pay attention to you.

Locomotive depot: What kind of unit is that? Central enterprises! Yang Ma's milk is fed, you still have to look at other people's faces.

"Really? Are you really sure? If you are sure, I will ask for their products, you make the mold in advance, and I will give you money! I will follow this list, and now there are many companies in China that do this kind of equipment, and we can directly match them with the main engine factory! ”

Hearing Ji Donglai say this, Tan Xiumei's eyes couldn't help but light up.

Coming to China from a foreign country, Tan Xiumei did not understand the various domestic policy scales and the relationship between enterprises belonging to the same level.

Seeing that Ji Donglai was so determined, and thinking about Ji Donglai's more and more mysterious ability at this stage, Tan Xiumei's heart that had just fallen was alive again.

"Of course you can, in the past two years, steelmaking will usher in a small peak, and the list of tamping machines will burst! It's still the same as before, you are responsible for sales, and I am responsible for production! Let's not delay, you make a lot of money, I make a little money! ”

Thinking of the next situation in the country, Ji Donglai resolutely assured Tan Xiumei.

Tan Xiumei nodded, and immediately the car did not leave at all, but went directly to the administrative office building, and Ji Donglai was waiting in the car.

In about half an hour, Tan Xiumei took down three drawings from upstairs.

"Take it, it's the position they drew with a pen in the middle, you calculate the cost and give it to me, and I'll give you cash!"

Taking off the mask, Tan Xiumei's face showed a rare lightness.

Ji Donglai just glanced at the drawings and knew it in his heart, asked Tan Xiumei about the demand for products, and then directly found a pen and paper on it and began to compose and calculate.

"One mold and sixteen cavities, the price of steel is two thousand one hundred and six, and the total cost of the mold is five thousand two! The mold fee was given, and I started to open the mold here, and then test the machine, and the skeleton was ...... Gotta be fine, fortunately I still have a little stock, otherwise I would be dumbfounded! ”

With his eyes closed, Ji Donglai began to think about the molding process, the other party's rubber spring skeleton was sealed, which reduced some of the pressure during molding, but at the same time, it also caused the internal space of the rubber to become solid.

The final result is that the heat generated by the rubber spring in the continuous shearing process cannot be released as it should be, and accumulates inside the rubber, resulting in self-aging.

This process seems to be very slow and insignificant, but the tamping machine moves very frequently, up and down hundreds of times per hour. If the rubber spring is hollow in the middle, when the spring is subjected to shear force, part of the deformation can be released in the hollow part, and the rubber will not generate so much heat.

The heat accumulation is smaller, and the aging rate of rubber is slower, which will naturally prolong the service life.

Ji Donglai's rubber formula is not as good as foreigners, this is a fact, then we have to work the application and process.

The rubber skeleton on the side is not blocked, so the thread is tightened with special-shaped bolts, and the protruding part of the bolt in the middle of the forming part leaves a little margin to ensure that there is enough space between the two sealing bolts to avoid molding problems.

The upper bolt can't be screwed by hand, it's too strenuous! On the electric screwdriver, the bolts must also be alloyed! The thread requires precision, and 8g with 6H is definitely enough.
