A strong technological nation starts with repairing mobile phones

Chapter 43 Rotational Molding!
Wednesday.

At 10:30 in the morning, Chen Jinghong brought several senior executives of the company to wait for the arrival of Wang Shoujun and Huang Qifan's team.

Huang Qifan did not stand up and arrived on time at the agreed time.

"Director Huang, President Wang, on behalf of Tiansheng Group, I welcome you!"

As soon as everyone got off the car, everyone in Tiansheng immediately walked towards them. Chen Jinghong, who was walking in the front, smiled.

"Mr. Chen, you are too polite. I feel very honored to visit your factory!" Huang Qifan said politely.

"Then let's go! Your time is precious so let's get straight to the point!"

"Haha, thank you for your help, Mr. Chen!"

The first stop for everyone was the most core department of Tiansheng Optics.

Glass melting furnace molding workshop.

As soon as they entered the workshop, Huang Qifan, Wang Shoujun and their team members were very tactful and put away their mobile phones.

They are all senior practitioners in the industry, and they naturally know the importance of confidentiality.

It was already very generous of Chen Jinghong to let them in to observe the production process. They naturally understood that it would be embarrassing if they filmed it.

"Our molding technology uses rotational molding, which perfectly avoids Corning Group's patented flow molding method.

Moreover, our rotational molding technology is more advanced than their flow molding method. The thickness of the molded glass is lower than theirs, and the substances in the glass are more evenly dispersed.

We are currently applying for a patent and I believe it will be approved soon.”

Chen Jinghong led everyone to the molding equipment, walked past the furnace, ignored the rice, and explained the molding equipment to them.

After finishing his explanation, he immediately pointed to some observation windows on the equipment and invited Huang Qifan and others to watch the molding process inside the equipment.

Huang Qifan naturally would not refuse. After all, he came here to find out more about Tiansheng Optics and see if it really had the real stuff.

Walking to the observation window of the equipment, Huang Qifan saw that the equipment was indeed forming by rotation. After watching it several times, he still couldn't figure out how the equipment completed this process.

In the end, he did not hesitate and immediately stepped back, signaling his team to go up and check and analyze it.

"This rotational molding method, does it really rotate? This is too simple, isn't it?" Wang Shoujun said this directly after reading it.

"Don't underestimate the simplicity of this. In fact, the knowledge behind it is very profound." A man in his fifties from Huang Qifan's team immediately exclaimed: "

The first problem to be solved in this rotational molding method is the centrifugal force problem. As we all know, during normal rotation, things will be thrown directly outwards. If this problem is not solved and things are left inside, there is no point in thinking about molding.

The second problem requires solving the stress problem. You know, the rotating glass is so thin that if this problem is not solved, I believe the whole piece of glass will shatter before it cools down!
As for this problem at present, I believe it is impossible to solve it, not only domestically but also abroad.”

After the other party finished speaking, he immediately turned to look at Chen Jinghong curiously, wanting to ask how Tiansheng's equipment solved the problem.

Chen Jinghong shook his head and said with a smile: "Haha, the patent has been applied for and the principles are all there. If you are interested, you can go and have a look. I won't waste your time here."

Then everyone continued to walk down, passed the cooling equipment and soon arrived at the exit.

When Huang Qifan and others arrived here, they immediately saw pieces of glass that had completely cooled down and looked like large wafers.

Chen Jinghong immediately took out a piece of glass from the production line, took the caliper handed over by Li Hanwu and started measuring it.

0.001!

0.1 mm, this piece of glass is only mm thick.

Chen Jinghong then measured ten places in succession, and without exception the thickness was exactly the same without any variation.

"Impossible, even Corning can't make this thickness!" Qin Weiguo said in disbelief. He is a senior engineer in the R&D department of OOPP Group and is very familiar with almost all materials for consumer-grade microelectronics products.

This familiarity is not just about parameters and usage, but also about having a certain understanding of the materials and accessories production processes of most suppliers.

He was very reluctant when he was notified today that he would be visiting a glass panel company he had never heard of.

It was not until he saw the new glass forming method just now that he finally became interested.

At this moment, I saw such thin glass appear in front of my eyes and I couldn't help it any longer.

He took the glass from Chen Jinghong's hand directly. As soon as he got it, he felt that this glass panel was indeed thinner than the glass he had touched before.

"Xiaoyu! Caliper!"

But he still chose to trust the tool and shouted directly to another younger person.

Yes, they also brought testing tools this time, including calipers.

The young man reacted quickly and handed the caliper to Qin Weiguo in less than ten seconds.

0.001, 0.001, 0.001, 0.001...

After one round, the tested values ​​were exactly the same as those just tested by Chen Jinghong without any surprises.

"It's impossible! Corning can't even produce glass this thin right now. How can it appear here? How can it appear here?"

Qin Weiguo simply couldn't accept it. According to his understanding, it was impossible for such an enterprise to exist in the country!

"Mr. Qin, it's ok, put it down first!" After reminding him, Huang Qifan turned to look at Chen Jinghong: "Mr. Chen, let's continue!"

Chen Jinghong had no objection and continued walking with Huang Qifan and others.

Cutting department, tempering department, coating department...

When we finished the tour, it was exactly twelve o'clock.

"Boss Huang, Boss Wang, are you ready to stay for dinner?"

"Forget it, I still have some things to do at the company, so I won't stay!" Huang Qifan shook his head and refused.

After this visit, Huang Qifan was almost certain that Tiansheng Optics really had core technology.

He couldn't wait to go back and discuss it with Qin Weiguo's team. If everything went well, he would arrange the things he promised to Chen Jinghong as soon as possible.

"Haha, I have something to do too. Let's do it next time! Next time we can set up a group and play together!" Wang Shoujun also said.

Seeing this, Chen Jinghong had no choice but to give up and took the senior executives to send a group of people to the factory parking lot.

"Mr. Chen, please stay. I will discuss this with them as soon as I get back. Don't worry, as long as we confirm what we agreed on last time, I will do it right away!"

After Huang Qifan finished speaking, he opened the car door, got in, and asked the driver to drive away from Tiansheng Optics.

"Leaving now? I don't know if the follow-up will be successful!" Zhou Pingshen stared at the factory gate and murmured.

"I never expected that Huang Qifan would come to our company in person!" This was said by Xu Liqing.

As the HR manager, he couldn't believe it when he first heard that Huang Qifan was coming. He still hadn't recovered from the shock until the other party left.

Looking at the convoy that had disappeared from sight, Chen Jinghong turned to look at everyone and said, "Let's go, let's go eat!"
