Return to the exciting era of 1999

Chapter 249
"Boss, are you busy?"

Ji Donglai was thinking about something, when there was a knock on the door, Ji Donglai turned his head, the expression on his face immediately changed from surprise to surprise.

"Old Zhai, you are finally back, how much good news did you bring us this time? Sit down!"

Patting the sofa beside him, Ji Donglai hurriedly poured water for Zhai Xiran.

At this stage, Zhai Xiran ran all over the country. After the enterprise in Hangzhou was on the right track, Ji Donglai almost didn't go there, and it was all run by his subordinates.

Now it seems that this is a very good decision. The entrepreneurial team headed by Yin Hongyan is doing well now, secretly with the help of Zhu Cunxin and his group. Now the production plan in Hangzhou is full every month. Already scheduled for next month.

Last month, Ji Donglai developed three products for Hangzhou Elevator Company, and now the craftsmanship has gone south.

"There are several good news and some bad news, which one do you want to hear first, Mr. Ji?"

Zhai Xiran sent a bunch of contracts like every time, and then his face was a little bad, Ji Donglai was stunned for a moment and motioned for the other party to continue talking.

Zhai Xiran didn't speak, but took out a few rubber spring products from his backpack. Ji Donglai didn't think anything at first, but when he looked closely, he immediately noticed something was wrong.

"This is a counterfeit of our product. The drawing of the elevator factory has not been changed until now. I changed it for you. Damn hippie, who is so bold?"

Looking at the few rubber springs in his hand, Ji Donglai's anger suddenly came up.

Ji Donglai knew that fake products were everywhere in this period, but he didn't expect that they would be imitated so quickly, and his own improvements would be imitated so quickly.

If the market is allowed to play freely, no one will be able to design it for at least five to ten years, and at least many people in the market will not be able to solve the cracking of iron scrapers.

It can happen even in large factories, not to mention those small factories that are shoddy. Ji Donglai has done it before. This time, he specially bought a vacuum pump and remodeled the injection molding machine. Structural patterns.

Otherwise, the rubber joint will still crack, which is determined by the fluidity of the product and the molding conditions.

"I'm checking. I don't know if it's from Hangzhou or Hebei. I suggest that in the future, our adhesives will remove any signs when they enter the site! Forming temperature and other things should be controlled centrally! By the way, you told me last time Material is the key, do you want to check along the rubber material?"

Zhai Xiran shook his head over there, rubber springs can be made in any workshop, and there is no way to find them.

However, the other party and Ji Donglai have talked a lot about rubber, which are usually used for sales, so I hurriedly reminded them.

"Don't think about it, this kind of rubber formula can be used in many shock absorbers. Although it is not universal, the raw material supplier doesn't want to tell us that no one can find it. The best way now is to refine the rubber by yourself. Wait until I figure out a way and find a decent rubber engineer!"

"Grandpa, that's what I do, sister, even I dare to copy, huh!"

Thinking about these things, Ji Donglai became angry, and chatted with Zhai Xiran about sales matters, and directly handed over the rest to the technical department. Ji Donglai called Zhao Shuying and a few core members, and immediately started discussing the field The matter of refining rubber.

"The internal mixer is not difficult. I'll make a call later, and we can make a set by ourselves! The internal mixer is just a few rollers. The people outside seem very sophisticated, and it's a no-brainer for us!"

"The rubber cutting machine is relatively simple, just a knife! As for dust removal, everything is simple, and the bag dust removal system plus a few centralized processing can solve it! I remember that there is a kind of machine in the world that is continuous honey refining. Japan, France, and Italy all Yes, Mr. Ji might as well look for it!"

"We can even buy one and copy it ourselves! If the amount is particularly large, we can try to make that. What comes out is a rubber strip, and the surface is coated with an isolation layer, which can be directly put on the injection molding machine!"

"Production is not the most time-consuming these days. The transfer and storage in the middle are the most time-consuming things. In addition, it is best to get the rubber mixing to the side. This thing is too dirty and makes people feel pimples! And , black rubber, white rubber, and some other special rubbers have to be separated!"

"Some rubbers are very dirty. After refining them, the machine has to be cleaned again, such as methyl rubber. If this stuff is not handled well, it will be a big trouble! And butadiene is not a fuel-efficient lamp!"

Although the core personnel of the technical department are not experts in rubber, when it comes to machinery, design, technology and production, they can almost open their mouths in the production industry.

This is professionalism, not just focusing on equipment, but also a deep understanding of this industry, Ji Donglai kept nodding.

As for the processing and manufacturing, it is very simple. The shell of the internal mixer is welded, and the rest of the base is cast and then bolted.

As for the mill, the entire base is cast, and the rolling roller is simpler, centrifugal casting, and the cost of making the whole equipment by yourself is three-quarters less than buying it from outside.

For the drawings of the equipment, Gao Gaohe called Dalian, and soon the detailed processing drawings arrived, and his subordinates transformed them and processed them directly.

As for rubber raw materials, Ji Donglai called Li Ming, and Li Ming recommended a bunch of suppliers. All the prices are based on the channel prices of Li Ming’s company. Zhao Shuying’s comprehensive calculation, the film price It was much lower than Ji Donglai's original purchase price.

More importantly, Ji Donglai directly controlled the rubber formula.

Especially when it comes to many main materials, the price will be increased by 30.00% through the intermediary. This time, Ji Donglai directly contacted the raw material manufacturer. The carbon black is a local petrochemical factory, and the synthetic rubber is also passed through these petrochemical companies.

Natural rubber is shipped from Yunnan, and enters Hebei via Tianjin Port, with a consumption of [-] tons each time.It just so happened that the other party entered the warehouse this time, and Ji Donglai picked up the goods directly.

"boom!"

"Damn it, this thing is really heavy!"

A big rubber block of [-] kilograms, a few young people in the office pushed the rubber block hard, the sweat on the face was splashing, and the clothes on the body were stained white.

As for the neoprene rubber, these [-]-kilogram chunks are also packed in bags, and they are like children in front of natural rubber.

"It's all money, if you have nothing to do, exercise, the man's waist is good, if you have nothing to do, buy some sheep's kidneys for two bites!"

Ji Donglai was not idle either, he loaded and unloaded two large bags, and handed over the rest to his subordinates.It is not difficult for the workshop workers to carry the rubber blocks, especially Da Qizi and his group, who can throw [-] kilograms of rubber blocks into the car by themselves.
