"Yeah, so loose?"

Seeing the bearing fall out, Tan Xiumei's big eyes blinked, and Ji Donglai nodded.

"Yes, he misled you! This is not hot-fitting, but a sealing embedded after assembly! Use something to press slightly on both ends of the bearing to seal the edges! This wheel cannot be cast if the quantity is large! Casting defects are easy to occur!

"

"If you look at this product, it seems to be fine, but there should be defects inside, otherwise the rubber wouldn't have penetrated so much. When he was turning and scraping the exterior rubber surface, he didn't bother to care about the defects, and they happened to be pitted!

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

"But from the looks of it, natural rubber should be added to it, which requires a lot of adhesive! So even though this thing is small, it requires a lot of engineering work! If you want to make it, use a stamping machine, form it in one go, and then turn the inner parts

hole! Then apply adhesive on the surface, and then hang the glue!"

"Using forging and fine blanking to form in one step can save a process, and there is no need to worry about defects! How much is the quantity of this thing?"

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

I consulted many so-called experts outside and gave them various suggestions. In the end, no one analyzed it for me. Ji Donglai broke it down directly. Just for one thing, Ji Donglai was reliable.

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

Just do it, I want it all!”

While the two were talking, Ji Donglai asked someone to peel off all the rubber on the guide wheel. It turned out that the roller was not made very carefully and did not even bother to use adhesive. It was just pockmarked.

"This is not an original part. If you dare to do this to an original part, you are seeking death!"

Pointing to the joint surface, Ji Donglai pointed it out to Tan Xiumei, and then talked about the huge harm that would occur. Tan Xiumei's eyes immediately lit up.

"you sure?"

Looking at Ji Donglai's confident look, Tan Xiumei looked full of energy.

"It is necessary. The original parts require that the bonding strength of this place reaches a certain level. This requires the application of adhesive! Do you know what adhesive is? This thing has two layers. The first layer is applied to the bottom. This part of the adhesive is

It can react chemically with metals!”

"The composite and metal produced can stand firmly together, and then the second layer of adhesive is responsible for chemically and physically reacting with the first layer of adhesive, and the two produce a cross-linking reaction! Then this layer of adhesive can also react with polyurethane to create a strong

Use the combined force of the handle to prevent the rubber from falling off!”

"Look at how hard the rubber was applied before it fell off. If the elevator runs for a long time, this kind of accident will definitely happen. If it doesn't work well, the elevator will get stuck! If it doesn't work well, the high-speed elevator will crash and kill everyone!"

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

This is not uncommon in China nowadays. It seems that this kind of thing happens in Shanghai or elsewhere, and it is not a small matter. At present, the supervision of various products is not strong, and the country will not issue relevant regulations in a few years.

"Okay, you go ahead and do it as you said! We will directly replace the original parts. Originally I wanted to start with the three guarantees, but now I see that there is no need for it. We will just get rid of the original parts. That supplier

Business now accounts for a huge share! Ji Donglai, do you know that you are going to get rich? Haha..."

Keeping what Ji Dong said firmly in her mind, Tan Xiumei secretly thought that she had met a noble person, and this time she must spend all her savings to win over this industry.

"can not do this!"

"Um?"

The result left Tan Xiumei stunned and Ji Donglai shook his head.

"I'm serious, I have no money!"

With such a large investment, Ji Donglai would not be so stupid as to advance the funds by himself!

If you ask me to do it, we will at least share the risk. Who knows if you can sell it? Besides, half of the elevator factory is supplied by foreigners, so we won’t see any money back in a short time. Ji Donglai

Worried about being dragged to death.

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

Seeing Ji Donglai decisively rejecting her, Tan Xiumei frowned.

"No problem, have you looked at the building over there? My grandfather has a staff dormitory over there, and he paid more than 100,000 yuan! And the equipment I rented here also costs money, and the workers' wages also need to be paid.

Money?”

"Following your instructions, I bought a lot of goods this time, which is also money! Also, if you want to make this thing now, do you have to find someone to cooperate with you in the first stage of forging wheel hub blanks?"

"If the advance payment is less, they won't open molds for you. Besides, you have to pay for the molds! It's also money for people to buy steel! We also need to open molds to make this wheel here, and that's also money! Buy bearings and rubber raw materials.

, after the test equipment is made, we need to do some dynamic balancing and try it!"

"Sister, this thing and a mobile phone case are two different concepts! If that thing breaks, it's fine, but if this thing breaks, it's fatal, so I'm helpless!"

Ji Dong spoke very calmly. At first, Tan Xiumei thought Ji Dong was playing tricks on her.

After listening to it later, I counted it on my fingers and found that it was indeed similar to what Ji Dong said.

Moreover, Ji Donglai, a small person, does not have a big business of his own, so there are certain difficulties in actually doing these things.

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

Tan Xiumei thought about it carefully and pointed at the dormitory building of Ji Donglai's house. Ji Donglai secretly cursed that if you put a tail on you, you would be like a monkey. You are really smart.

"You think I don't want to? The real estate certificate hasn't been in my hands yet. Although it is said to be given in July, who knows? You know how efficient these people in China are at doing things. It will be possible for you by this time next year. You can't complain yet!

Only those who don’t have a real estate certificate will give you a loan!”

"I'm not you, driving a big cross-country back and forth. Sister, why don't you find someone else? I'll tell you about craftsmanship and everything else. It's not that I don't want to do this. Seeing that I can't get the money makes me feel more uncomfortable than you!"

The implication of Ji Donglai's words is just one sentence, I want to do it but have no money!

In fact, it is a hint to Tan Xiumei, you can either take away these goods you asked me to store and give me the money for turnover. Or you can give me the advance payment now, or else? Find someone else to make products for you.

Just now Ji Donglai seemed to have spoken in detail, but the actual operation was very difficult.
