Return to the exciting era of 1999

Chapter 341
At the beginning, Ji Donglai was purely to support these people, and then he started to make the whole set of equipment. He didn't want to bring such a big bonus to himself because of this, at least it didn't take any effort when connecting with the outside world.

"Mr. Ji, did you also process the mixing screws here?"

Turning around the machinery and equipment, the old man's face was full of astonishment, and his expression became complicated when he saw Ji Donglai.

"Well, there was a small twist in the middle. At the beginning, we used the domestic CNC machine tool to make the rotor, but it turned out that it was off by one degree. After calculation, it turned out to be better than the original drawing. So we made the second batch of internal mixer. The rotor has changed the model, and now the patent registration has been completed!"

"In addition, our squirrel-cage sealing spacer ring has also completed a patent. Of course, you call it a labyrinth mechanical seal. If you have any needs, you can also contact us. The previous copper ring seals leaked, and they are sold at home and abroad. It has not been solved. This time it can be solved thanks to our masters, only the precision of the things they process is sufficient."

Ji Donglai let the old man into the lounge and poured him a glass of water. Hearing that the labyrinth-like sealing structure could seal the material, the other party opened his mouth and whispered something to his subordinates.

The other party hurried back to the conference room, and brought the old man's folder within a short time.

"Mr. Ji, is this the squirrel-cage sealed structure you're talking about?"

Speaking of the old man handing a stack of documents to Ji Donglai, Ji Donglai was stunned the first moment he picked up the documents, because the structure was too similar.

In my heart, I have to admire several masters under my command. The watermark of the document in front of me is top secret, so I can see it is very important. Now that my company has registered a patent, I don't even know the value of this thing. Ji Donglai He secretly thought that he was guarding the gold mine and begging for food.

"Your structure is a bit old. If you continue to use this structure, I think there will still be material leakage. If you need to process, please provide us with the operating environment parameters of your equipment, and then various other conditions, especially the physical properties of the material. Most importantly, friction coefficient and particle size are all needed! We design it for you according to the operating conditions of your equipment, and your structure is 100% leaking!"

With his own patent bonus in hand, Ji Donglai would not choose to process ready-made ones for the other party, and Ji Donglai is sure that the other party must have leaked the material, otherwise the other party would not be so anxious to show him the drawings.

"Mr. Ji, can you be sure that your structure will not leak? This problem has plagued our entire team for more than ten years. Many foreign designers have also made various plans for us, but they are always unsatisfactory. Once, this sealing structure is basically unusable, you know?"

Speaking of the issue of sealing, the old man's eyes were full of helplessness.

Since the development of this set of equipment, the other party has made more than one set of plans, all of which ended in failure without exception. Not to mention, the heat dissipation and dynamic balance alone caused the old man to collapse.

Such a large amount of mixing, continuous discharge, the mixing ratio is even more appropriate.The screw is continuously heated, and the silo is continuously heated, all of which are destined to require a sealing structure that can adapt to the thermal curve.

Several foreign materials have been tested, without exception, either holding tiles or wearing out, or simply leaking materials.The Foreigner Design Institute gave up, let alone Wanwan.

"Hehe, do you know how much material our factory uses in a day? I'm talking about black rubber!"

Seeing the worried look of the old man, Ji Donglai stood up with a smile and waved his hands. Ding Aixing instructed the workers to open the rolling shutter door at the back.

"This is……"

As the door of the warehouse opened, black rubber blocks were neatly piled up into a mountain.Bags of raw materials, carbon black, neoprene blocks, and various small materials are piled up at least tens of meters away.

"Black rubber is [-] tons per day, and white raw material is more, of course, it is another rubber material! Such a large amount, can your equipment achieve this amount?"

"In addition, I am worried that the sealing problem you mentioned may not be the sealing, but the thermal balance system is not done well. If you trust us, we can jointly develop. You lead the team in our laboratory, bring the drawings, and we process them while processing. Research, when the equipment is successfully delivered, helps you solve the problem."

"Of course, this is just our wishful thinking. It's better to be like this, otherwise we really can't guarantee whether the sealing can meet your requirements. After all, there are too many factors that affect the sealing, especially once the dust enters the second division, some of them can Blow it back, most of the time it will cause damage to the seals..."

Ji Donglai tried his best to get more business for his company, but the old man nodded, but he didn't hurry to agree, after all, he couldn't decide on this matter alone.

That night, when everyone returned to the hotel, the old man declined Ji Donglai's banquet. In the conference room of the hotel, the company's top management held a temporary shareholder meeting.

"Absolutely not, I don't agree with putting this equipment on your side for processing, not to mention getting our core stuff there for processing, that's even more unacceptable, we will be copied, and the people on their side are very unethical!"

"Yes, we absolutely can't do this. Do you think we have been imitated too few devices these years? Never give them the core things, it will cause big problems."

"Ji Donglai can produce seals for us according to the drawings, but we must not use their products. The people over there are very bragging, you know..."

Faced with the old man's request to establish a joint development with Ji Donglai, the shareholders' meeting unanimously refuted it for one reason. They did not believe in Ji Donglai's strength and professional ethics.

"Leaders, we have checked the situation of Ji Donglai's factory. This company is indeed very powerful. If their laboratory is really completed, then we can really cooperate here. After all, once the cooperation is successful , we can avoid taxes here, and solve the hidden dangers of equipment..."

When it comes to the future, the old man's eyes are full of expectations. After all, there are not many people under him who can be as strong as Ji Donglai's team.

"Don't tell us that. We will get the money back for this batch of equipment first, and then we will do other things after we get it. What do you want to do so much now?"

"That's right, get all the money in your hands first, and now your task is to implement, not to mess up messy things, that's it! Giving you the processing equipment over there is the maximum authority!"

Several shareholders hardly gave the old man a second chance to speak. In this way, the old man failed again. He had no choice but to hand over the traditional equipment parts to Ji Donglai the next day. As for the core seals and internal refining Machine screws are handed over to overseas suppliers.
