"Boss, are you busy?"
Ji Donglai was thinking about something when there was a knock on the door. Ji Donglai turned around, his expression immediately changed from surprise to surprise.
"Old Zhai, you are finally back. How much good news have you brought us this time? Sit down quickly!"
Patting the sofa next to him, Ji Donglai hurriedly poured water for Zhai Xiran.
At this stage, Zhai Xiran traveled all over the country. After the company in Hangzhou was on the right track, Ji Donglai almost didn't go there. It was all run by a few of his subordinates. qs
Now it seems that this is a very good decision. The entrepreneurial team headed by Yin Hongyan is now doing well. Secretly with the help of Zhu Cunxin and others, the production plan in Hangzhou is now full every month, and some plans Already scheduled for next month.
Last month, Ji Dong came here and developed three products for the Hangzhou Elevator Company. Now the technology has moved south.
"There is some good news and some bad news. Which one do you want to hear first, Mr. Ji?"
Zhai Xiran presented a bunch of contracts as he did every time, and then his face became a little bad. Ji Donglai was stunned for a moment and motioned for the other party to continue.
Zhai Xiran didn't say anything, but took out several rubber spring products from his backpack. Ji Donglai didn't think anything at first, but after taking a closer look, he immediately noticed something was wrong.
"This is a counterfeit of our product. The elevator factory's drawings have not been changed until now. I changed this. Damn hippie, who is so bold?"
Looking at the rubber springs in his hands, Ji Donglai suddenly became angry.
Ji Donglai knew that copycat products were everywhere during this period, but he did not expect that they would be imitated so quickly, and that 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. At least many people in the market will not be able to solve the problem of cracking of the iron scraper.
It happens even in large factories, not to mention those small factories that make shoddy products. Ji Donglai has worked there before. This time he bought a vacuum pump and modified the injection molding machine. At the same time, he used a different design from the one at the elevator factory. 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 whether it's from Hangzhou or Hebei. I suggest that our adhesives be removed from any labels when they come in from now on! The molding temperature and other things should be controlled centrally! By the way, you told me about the adhesive last time. Material is the key, do you want to check along the rubber material?"
Zhai Xiran shook his head. Rubber springs can be made in any workshop, so there is no way to find them.
However, the other party had talked a lot about rubber with Ji Donglai, which was usually used for sales, so he quickly reminded him.
"Don't think about it. This kind of rubber formula can be used in many shock-absorbing applications. 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 yourself. Let me think of a way to find a decent rubber engineer to come over!"
"Grandpa, this is what I do, sister, even I dare to plagiarize, huh!"
Thinking about these things, Ji Donglai became angry. He chatted with Zhai Xiran about some sales matters and handed over the rest of the matters directly to the technical department. Ji Donglai called Zhao Shuying and several core members and immediately began to discuss the situation. The matter of refining rubber.
"It's not difficult to get the internal mixer. I'll make a call later and we can make one ourselves! The open mixer is just a few rollers. People outside look very high on it, but we are just a piece of cake!"
"The glue cutting machine is relatively simple, just a knife! As for dust removal, everything is simple. A bag dust removal system plus a few centralized processes can solve the problem! I remember that there is a machine in the world that uses continuous honey refining. Japan, France, and Italy all have it. Yes, Mr. Ji might as well look for it!"
"We can even buy one and copy it ourselves! If the dosage is particularly large, we can try to make it. What comes out is a rubber strip, put an isolation layer on the surface, and it can be put into the injection molding machine directly!"
"Production these days is not the most time-consuming thing. The transportation and storage in the middle are the most time-consuming thing. In addition, it is best to put the rubber mixing to the side. This thing is too dirty and makes people get pimples when it gets on the body! Also! , black rubber, white rubber, and others
Some of his special rubber has to come apart! "
"Some rubbers are very dirty. After refining them, the machine needs to be cleaned, such as methyl rubber. It's really annoying if you don't get it right! Also, cis-butadiene is not a fuel-efficient lamp!"
Although several core personnel in the technical department are not experts in rubber, when it comes to machinery, from design to process and production, the production industry is almost open to the public.
This is professionalism, not just focusing on equipment, but also an in-depth understanding of the industry. Ji Donglai kept nodding.
As for the processing and manufacturing, it is very simple. The casing of the internal mixer is welded, and the rest of the base is cast and then bolted.
As for the open mill, the entire base is cast, and the rolling rollers are simpler and centrifugally cast. Making the entire equipment yourself saves three-quarters of the cost compared to buying it from outside.
For the drawings of the equipment, Gao Zhonghe made a call to Dalian, and soon the detailed processing drawings arrived. His subordinates converted them and processed them directly.
As for the rubber raw materials, Ji Donglai called Li Ming. Li Ming recommended a bunch of suppliers. All prices were based on Li Ming's channel prices. Zhao Shuying made a comprehensive calculation and found out the film prices. 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% through intermediaries. This time Ji Donglai directly contacted the raw material manufacturers. The carbon black was from local petrochemical plants, and the synthetic rubber also went through these petrochemical companies.
Natural rubber is shipped from Yunnan and enters Hebei through Tianjin Port, with a consumption of 50 tons each time. It happened that this time the other party entered the warehouse, and Ji Donglai took delivery of the goods directly.
"boom!"
"Holy shit, this thing is so heavy!"
A large rubber block weighs 500 kilograms. Several young people working in the office struggled to push the rubber block. The sweat on their faces was pouring and the clothes on their bodies were dyed white.
As for neoprene, these 70-kilogram chunks are also packed in bags. They are like children in front of natural rubber.
"This is all money. If you have nothing to do, do some exercise. A man's waist is good. If you have nothing to do, buy some sheep kidneys and eat them!"
Ji Donglai was not idle either. He loaded and unloaded two large bags and handed the rest to his subordinates. It is not difficult for the workers in the workshop to carry the rubber blocks, especially Da Qizi and his group. One person can directly throw 500 kilograms of rubber blocks into the car.
