At the beginning, Ji Donglai was purely to support these people, and then he started to make a whole set of equipment, he didn't want to bring such a big wave of dividends to himself because of this, at least he didn't have to work hard when he was docking with the outside world.

"Mr. Ji, the mixing screw in this is also processed by yourself?"

Walking around the machine and equipment, the old man's face was full of consternation, and he looked at Ji Donglai's expression with a complicated expression.

"Sort of, there was a little twist and turn in the middle, at the beginning we used the rotor made of domestic CNC machine tools, but it turned out to be a deviation of one degree, and then after calculation, it turned out to be better than the original drawings, so the rotor of our second batch of internal mixers was changed to a different model, and now the patent registration has been completed!"

"In addition, now our squirrel cage sealing spacer ring has also completed the patent, of course, you call it a labyrinth mechanical seal, if you need it, you can also contact us, the previous copper ring seal is leaking, and it has not been solved at home and abroad. This time it can be solved thanks to our masters, only the precision of their processing is enough."

Ji Donglai let the old man go to the lounge and poured a glass of water for the other party, and when the other party heard that the labyrinthine sealing structure could seal the material, his mouth opened and beckoned his subordinates to whisper.

The other party hurriedly ran back to the conference room, and it didn't take long to bring the old man's folder.

"Mr. Ji, is this the squirrel cage sealing structure you are talking about?"

Saying that, the old man sent a stack of documents to Ji Donglai, and 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 a few masters under me, the watermark of this document in front of me is top secret, and it can be seen that it is very important, and my company has now registered a patent, and I don't even know the value of this thing, Ji Donglai secretly said that he was guarding the gold mine and asking for food.

"Your structure is a bit old, if you continue to use this structure, I think there will be leakage, if you need to process, provide us with the operating environment parameters of your equipment, and then all kinds of other conditions, especially the physical properties of the material are the most important, friction coefficient, granularity are all needed! We design it for you according to the operating conditions of your equipment, and your structure is 100% leaky!"

With his own patent dividends in hand, Ji Donglai will not choose to process ready-made ones for the other party, and Ji Donglai is sure that the other party will definitely leak materials, otherwise the other party will not be in such a hurry to show the drawings to himself.

"Mr. Ji, can you be sure that your structure will not leak? This problem has plagued our entire team for more than ten years, and many foreign designers have also made various plans for us, but they are always not ideal.

When it came to 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.

With such a large amount of mixture, continuous discharge, the mixing ratio is more appropriate. The continuous heating of the screw and the continuous heating of the silo doomed these things to require a sealing structure that could adapt to the thermal curve.

Several foreign materials have been tested, without exception, either the tile is worn out, or simply leakage. The foreigner design institute has given up, not to mention the bend.

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

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

"It's ......"

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

"Fifteen tons of black rubber a day, more white material, of course that's another kind of rubber! With such a large amount, can your device reach this amount?"

"In addition, I am worried that the sealing problem you mentioned may not be sealed, but the thermal balance system is not done, if you believe us, we can jointly develop, you lead the team in our laboratory, with drawings, we process and research, and help you solve the problem when the equipment is successfully delivered."

。」

"Of course, this is just our wishful thinking, preferably so, otherwise we really dare not guarantee that the seal can meet your requirements, after all, there are too many factors affecting the seal, especially once the dust enters the second partition, some can be blown back, and most of it will cause the seal to break......

Ji Donglai tried his best to give his company a little more business, the old man nodded, but he didn't rush to agree, after all, this thing is not something that he can decide alone.

That night, everyone returned to the hotel, the old man declined Ji Donglai's banquet, and in the conference room of the hotel, the company's senior management held an extraordinary shareholders' meeting.

"Absolutely not, I don't agree with putting this equipment on their side for processing, not to mention just getting our core things over for processing, that's even worse, we will be copied, and the people on their side are very immoral!"

"Yes, we can't do that, do you think we've had fewer devices copied over the years? Don't give them the core stuff, it's going to be a big problem."

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

In the face of the old man's request to establish a joint development with Ji Donglai, the shareholders' meeting unanimously refuted it for one reason, not believing in Ji Donglai's strength and professional ethics.

"Leaders, we 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......

Speaking of the future, the old man's eyes were full of expectations, after all, there were not many people under his command who could have the same strength as Ji Donglai's team.

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

"That's it, get all the money in your hands first, now your task is to implement, not mess up, that's all! Giving you the most permission to process equipment over there is already the greatest permission!"

Several shareholders almost did not give the old man a second chance to speak, and in this way, the old man's second attempt failed, and he had no choice but to hand over the traditional equipment parts to Ji Donglai the next day, and the core seals and mixer screws to overseas suppliers.
