Ji Dong came here purely to support this group of people, and then started to make a complete set of equipment. He didn't expect that this would bring him such a big wave of dividends. At least it would be effortless to connect with the outside world.
"Mr. Ji, do you also process the mixing screws here yourself?"
After walking around the machinery and equipment, the old man's face was full of astonishment, and he looked at Ji Donglai with a complicated expression.
"Well, there were a few twists and turns. At first we used a domestic CNC machine tool to make the rotor, but it turned out to be one degree off. Later, after calculations, it turned out to be better than the original drawings, so we made the second batch of internal mixers. The rotor model has been changed, and now the patent registration has been completed!"
"In addition, our squirrel cage seal spacer ring has also been patented. Of course, you call it a labyrinth mechanical seal. If you have any needs, you can contact us. The previous copper ring seals leaked material, both at home and abroad. None of them have been solved. The solution this time is thanks to our masters. Only the things they process are accurate enough."
Ji Donglai let the old man into the lounge and poured him a glass of water. When the other man heard that the labyrinth sealing structure could seal materials, he opened his mouth and whispered something to his men.
The other party hurried back to the conference room and brought the old man's folder in a short time.
"Mr. Ji, is this the squirrel cage sealing structure you are talking about?"
As he spoke, the old man handed a stack of documents to Ji Donglai. Ji Donglai was stunned the first moment he picked up the documents because the structures were so similar. .
In my heart, I have to admire the few masters under me. The watermark of the document in front of me is top secret. It can be seen that it is very important. However, my company has now registered a patent. I don't even know the value of this thing. Ji Donglai He secretly said 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, provide us with the operating environment parameters of your equipment, and then various other conditions, especially the physical properties of the materials. Importantly, the friction coefficient and particle size are all required! We design it for you according to the operating conditions of your equipment, and your structure will leak 100% of material!"
With his own patent dividend in hand, Ji Donglai would not choose to process ready-made products for the other party, and Ji Donglai was sure that the other party must have leaked materials, 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 materials? This problem has troubled our entire team for more than ten years. Many foreign designers have also made various plans for us, but they are always not ideal. After disassembling the two This time, this sealing structure is basically useless, you know?"
When talking about 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 plan, and without exception, they all ended in failure. Not to mention, the heat dissipation and dynamic balancing alone made the old man collapse.
With such a large mixing volume and continuous discharging, the mixing ratio is even more appropriate. The screw continues to heat, and the silo continues to heat. All of this is destined to require a sealing structure that can adapt to the thermal curve.
Several foreign materials have been tested, and without exception, either the tiles are stuck or worn, or the material is simply leaking. The Foreign Design Institute has given up, let alone Wanwan.
"Haha, do you know how much material our factory uses in a day? I'm talking about black rubber!"
Looking at the old man's worried look, Ji Donglai stood up with a smile, waved his hand, and Ding Aixing directed the workers to open the rolling shutter door at the back.
"This is……"
As the door of the warehouse opened, black rubber blocks were piled neatly into a mountain. Bags of raw materials, carbon black, neoprene blocks, and various other small materials were piled at least dozens of meters away.
"The black rubber is fifteen tons per day, and the white rubber is even more. Of course, it is a different rubber material! With such a large amount, can your equipment be able to achieve this amount?"
"In addition, I am worried that the sealing problem you mentioned may not be the sealing, but the heat balance system is not done well. If you believe us, we can jointly develop it. You can lead the team in our laboratory and bring the drawings, and we will process it while Research to help you solve the problem when the equipment is successfully delivered
. "
"Of course this is just our wishful thinking, and it's best to be like this, otherwise we really can't guarantee whether the seal can meet your requirements. After all, there are too many factors that affect sealing, especially once the dust enters the second zone, some of them can Blowing it back will most likely cause damage to the seal..."
Ji Donglai tried his best to get more business for his company. The old man nodded, but did not agree in a hurry. After all, this was not something he could decide by himself.
That night, everyone returned to the hotel. The old man declined Ji Donglai's banquet. In the hotel's conference room, the company's senior management held an extraordinary shareholders' meeting.
"Absolutely not. I don't agree with putting this equipment in their place for processing, not to mention that our core stuff has just been processed there. That is even more unacceptable. We will be copied. The people over there are very unethical!"
"Yes, we absolutely can't do this. Do you think our equipment has been imitated a lot over the years? Don't give them the core stuff, that will cause big problems."
"Ji Donglai can produce seals for us according to the drawings, but we must not use their stuff. 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.
"Dear 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..."
Speaking of the future, the old man's eyes were full of expectations. After all, not many of his men could be as strong as Ji Donglai's team.
"Don't tell us that. Let's get the money back for this equipment first. After we get it, we can do other things. Why do you think so much about it now?"
"That's it, let's get all the money first. Now your task is to implement it, not to make a mess, that's it! Giving you the maximum authority to process the equipment there!"
Several shareholders barely gave the old man a second chance to speak. In this way, the old man's try again failed. He had no choice but to hand over the traditional equipment parts to Ji Donglai the next day. As for the core seals and mixing The machine screws are handed over to overseas suppliers.
