Return to the exciting era of 1999

Chapter 79 I Can't Do This Job

"Yeah, so loose?"

Watching the bearing fall out, Tan Xiumei blinked her big eyes, and Ji Donglai nodded.

"Yes, he misled you! This is not hot-mounted, but the seal after assembly is embedded! The two ends of the bearing are slightly pressed with something to seal the edge! This wheel cannot be cast if the quantity is large! Casting is prone to defects! "

"Look at this product, it seems that there is no problem, there should be defects inside, otherwise the rubber wouldn't go in so much, and he didn't bother to care about the defects when he turned the outer scraping surface, it happened to be pockmarked!

"As for the cushioning material on the surface, it's not rubber, it's called modified rubber, it's actually plastic, polyurethane! This thing is wear-resistant, and its cushioning performance is also good, and its aging resistance is also good!"

"However, it should be that natural rubber is added in it, which requires a lot of adhesives! So don't look at this thing as small, it requires a lot of engineering! If you want to make it, find a stamping machine, form it at one time, and then turn the inner part. Hole! Then brush the surface with adhesive, and hang the glue!"

"Using forged fine blanking can save one process and don't have to worry about defects! How big is this thing?"

Looking at this little thing that he was no longer familiar with, Ji Donglai talked eloquently, while Tan Xiumei stared with big surprised eyes, secretly thinking that he had found the right person.

I consulted a lot of so-called experts outside and gave various suggestions, but no one analyzed it for me. Ji Donglai directly broke it down. It was aimed at one thing, and Ji Donglai was reliable.

"It's very big. I'm still exporting. I keep half of the products in China and send them to Guangzhou, Beijing, Tianjin and Shanghai! We have to make it bigger. In the future, all their products will use my products. Can you do it? Just do it, I want it!"

While the two were talking, Ji Donglai asked someone to peel off all the rubber on the guide wheel. Facts have proved that this roller was made very carelessly, and he didn't even bother to use the adhesive, it was just a pockmarked surface.

"This is not the original part, if the original part dares to do this, it is courting death!"

Pointing to the junction, Ji Donglai pointed it out to Tan Xiumei, and then talked about the great harm that would happen, Tan Xiumei's eyes lit up immediately.

"Are you sure?"

Looking at Ji Donglai's confident look, Tan Xiumei looked radiant.

"Must, 100% of the original parts require that the bonding force of this place meets a certain requirement. This is where the adhesive must be applied! Do you know what is an adhesive? This thing has two layers. The first layer is applied to the bottom. This part of the adhesive is the Metals can react chemically!"

"The composite and metal produced can stand firmly together, and then the second layer of adhesive is responsible for the chemical and physical reaction with the first layer of adhesive, and the two have a cross-linking reaction! Then this layer of adhesive can also react with polyurethane to produce a firm Let's work together! Keep the rubber from falling off!"

"Look at how hard the rubber has been used before it falls off. If the elevator runs for a long time, this kind of accident will happen 100% of the time. If it is not done well, the elevator will be stuck! If the high-speed elevator is not done well, the machine will crash and people will die!"

Ji Donglai didn't know what Tan Xiumei meant, but there were many cases in his mind.

This is not uncommon in China at present. It seems that this kind of thing will happen anywhere in Shanghai, and it is not a small matter.At present, the supervision of various products is not strong, and the country will not introduce relevant laws and regulations in a few years.

"Okay, you do it, just do what you said is good! We will directly replace the original factory. Originally, I wanted to start with the three guarantees, but now I don't see any need for it. We just get rid of the original factory. Shang now occupies a large share! Ji Donglai, do you know that you are going to get rich? Hehe..."

Keeping what Ji Dong said firmly in her mind, Tan Xiumei secretly thought that she had met a nobleman, and this time she must take out all her savings and take down this property.

"can not do this!"

"Ok?"

As a result, Tan Xiumei was stunned, and Ji Donglai shook his head.

"I'm serious, no money!"

With such a large investment, Ji Donglai wouldn't be so stupid to advance the funds by himself!

If you ask me to do it, the two of us at least share the risk. Who knows if you can sell it?Besides, half of the elevator factories are suppliers that are agents of foreigners, and if they don't see the money back in a short time, Ji Donglai is worried that he will be dragged to death.

"Didn't the last batch of mobile phone cases make money? Are you worried that I won't give you money?"

Seeing Ji Donglai decisively reject her, Tan Xiumei frowned.

"Nothing, have you looked at the building over there? My grandfather has a staff dormitory building over there, and he paid a supplementary one hundred thousand! Also, the equipment I rented here also costs money, and the wages of the workers do not matter. money?"

"According to your instructions, I have bought a lot of goods this time, and this is money! Also, if you want to make this thing now, do you have to find someone to cooperate with you in the forging wheel blank?"

"If there is less advance payment, they won't open the mold for you. Besides, you have to pay for the mold! It's money for people to buy steel! We also need to open molds for this wheel here, which is also money! Buy bearings and rubber raw materials , the test equipment, after we make it, we need to do a dynamic balance to try!"

"Sister, this thing and the phone case are two different concepts! It's okay if the thing is broken, but it's terribly broken, so I'm powerless!"

Ji Dong said it very frankly, at first Tan Xiumei thought Ji Donglai was playing tricks on her.

After listening to it, I counted it with my fingers, and it was indeed similar to what Ji Dong said.

Besides, Ji Donglai, a small person, is not his great cause, so there are certain difficulties in doing these things.

"Don't you have a house in your family? Wouldn't it be good to have a loan?"

Tan Xiumei thought about it carefully, and just happened to point to the dormitory of Ji Donglai's house. Ji Donglai cursed secretly that you would be a monkey if you put a tail in it.

"You think I don't want to? The real estate certificate is not in my hands yet. Although it is said that I will give it in July, who knows? You know the efficiency of these people in China. It is possible for you this time next year. You can't complain! Only a house ghost without a real estate certificate will give you a loan!"

"I'm not you. I drive a big off-road back and forth. Sister, why don't you find someone else? I'll tell you everything about craftsmanship. It's not that I don't want to do it. I feel more uncomfortable than you when I don't get the money!"

Ji Donglai's implication is just one sentence, I want to do it without money!

In fact, it was hinting to Tan Xiumei that you either take the goods you let me store up and give me the money for turnover.Either you give the advance payment now, or not?Get someone else to make the product for you.

Just now, Ji Donglai seemed to have explained it in detail, but in practice it was very difficult.
