"Boss, are you busy?"

Ji Donglai was thinking about things, there was a knock at the door, Ji Donglai turned around, and the expression on his face immediately changed from surprise to surprise.

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

patting the sofa next to him, Ji Donglai hurriedly poured water for Zhai Yiran.

At this stage, Zhai Yiran ran all over the country, and after the enterprises in Hangzhou were on the right track, Ji Donglai almost didn't go, and a few of his subordinates were running. qs

Now it seems that this is a very good decision, the entrepreneurial team led by Yin Hongyan is now doing well, with the help of Zhu Cunxin's gang in secret, and now the production plan in Hangzhou is full every month, and some plans have been scheduled for next month.

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

"There are a few good news, and there are a few bad news, which one do you want to hear first?"

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

Zhai Yiran didn't speak, but took out a few rubber spring products from his backpack, Ji Donglai didn't feel anything at first, but after looking closely, he immediately found that something was wrong.

"This is a counterfeit of our product, and the drawings of the elevator factory have not been changed until now, this is what I changed, mother hippie, who is so bold?"

Looking at the few rubber springs in his hand, Ji Donglai's anger came up all of a sudden.

Ji Donglai knew that copycat products were everywhere during this period, but he didn't expect them to be imitated so quickly, and his own improvements were imitated so quickly.

If the market is allowed to play freely, at least no one can design it for five to ten years, at least the cracking of iron squeegee rubber cannot be solved by many people in the market.

Even large factories will happen, not to mention those shoddy small factories, Ji Donglai has worked before, this time specially purchased a vacuum pump, transformed the injection molding machine, and adopted a different structural model from the elevator factory.

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

"I'm investigating, I don't know if it's from Hangzhou or Hebei, I suggest that our adhesives will be removed directly from the market in the future! Molding temperature, these things are centrally controlled! By the way, you told me last time that the rubber compound is the key, do you want to check the rubber material along with it?"

Zhai Yiran shook his head, rubber springs can be done in a workshop at will, and they can't be found at all.

However, the other party and Ji Donglai talked about a lot of rubber things, which are usually used for promotion, so they hurriedly reminded them.

"Don't think about it, this rubber formula can be used in a lot of shock absorption, although it is not universal, but the raw material supplier does not want to tell us that no one can find out, now the best way is to refine the rubber by yourself, and when I want to find a way, find a decent rubber engineer!"

"Grandpa, that's what I'm doing, sister, even I dare to plagiarize, hum!"

Thinking about these things, Ji Donglai was angry, chatted with Zhai Yiran about a little sales matter, and directly handed over the rest of the things to the technical department, Ji Donglai called Zhao Shuying and a few cores, and immediately began to discuss the matter of refining rubber in this field.

"It's not difficult to get the mixer, I'll make a phone call later, let's make our own!" The mill is just a few rollers, and the people outside look very deep, and they are all small dishes for us!"

"The glue cutter is relatively simple, it's just a knife! As for dust removal, everything is simple, and the bag dust removal system plus a few centralized treatments can solve it! I remember that there is a kind of machinery in the world that is continuous honey refining, Japan, France, and Italy have it, so Mr. Ji might as well look for it!"

"We can even buy one back and make our own! If the dosage is particularly large, we can try to make that, and what comes out is the adhesive strip, and the surface is smeared with an isolation layer, and it can be directly put on the injection molding machine!"

"This year, production is not the most time-consuming, the transfer and shelving in the middle are the most time-consuming things, and it is better to get the rubber to the side, this thing is too dirty, and it makes people pimple on the body! Also, black rubber, white rubber, and its

Some of his special rubbers have to be separated!"

"There are some rubbers that are particularly dirty, and after refining them, the machine has to clean them again, such as methyl rubber, which is *** annoying if you don't get it right! And Shunding is not a fuel-efficient lamp!"

Although several core personnel of the technical department are not experts in rubber, when it comes to machinery, from design to process and production, the doorway of the production industry is almost open.

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 shell of the internal mixer is welded, and the rest of the base is cast, and then bolted.

As for the open mill, the whole base is casting, the rolling roller is simpler, centrifugal casting, and the whole equipment is made by itself to save three-quarters of the cost compared with the outside purchase.

The drawings of the equipment, Gao Gao He gave a phone call to Dalian, and soon the detailed processing drawings arrived, and the subordinates converted it and processed it directly.

As for the rubber raw materials, Ji Donglai called Li Ming, and Li Ming introduced a bunch of suppliers in the middle, all the prices were according to the channel prices of Li Ming's company, and Zhao Shuying's comprehensive calculation showed that the price of film was much lower than Ji Donglai's original purchase price.

More importantly, Ji Donglai directly controlled the rubber formula.

Especially involving a lot of main materials, through the intermediary to increase the price by 30%, this time Ji Donglai directly contacted the raw material manufacturers, carbon black is a local petrochemical plant, synthetic rubber is also through these petrochemical companies.

Natural rubber is shipped from Yunnan and enters Hebei through Tianjin Port, with a dosage of 50 tons each time. It happened that the other party entered the warehouse this time, and Ji Donglai picked up the goods directly.

"Bang!"

"Holy, this thing is so heavy!"

Five hundred kilograms of a large rubber block, a few young people in the office who were busy pushing the rubber block, sweat beads on their faces, and the clothes on their bodies were dyed white.

As for neoprene, these 70-kilogram chunks are also bagged, and they are like children in front of natural rubber.

"It's all money, exercise if you have nothing to do, a man's waist is good, it's okay to buy some lamb kidneys and eat two bites!"

Ji Donglai was not idle, followed by loading and unloading two large bags, and handed over the rest to his subordinates. It is not difficult for the workshop workers to carry rubber blocks, especially the Daqizi gang, one person can directly throw 500 kilograms of rubber blocks into the car.
