623 Chapter 622 Optical Fiber Production Line (1) [seeking subscription]

"I agree with all the decisions you made." Xu Zhenming waved his hand and said he had no opinion.For small CASE projects like PLC, he believes that there is no need to restrict the free thinking of his technical team.

Having said this, he and He Changlin sat down in the back of the conference room to find a seat and participated in this technical discussion, but they did not participate in the technical discussion.

"Everyone, consider the poor level of domestic power supply manufacturers. Our YM-PLC regulated switching power supply must be designed and produced by ourselves. Do you have any comments?" Team leader Wang saw that the boss Xu Zhenming really delegated power this time. The meeting continued somewhat cautiously.

Participants are all engineers, and once technical issues are involved, they will be very involved.They quickly forgot the existence of Xu Zhenming and He Changlin.

"Group leader Wang, the CPU needs to be redesigned, and the cost of YM-01 is too high."

"Yes, it's best to design a series of CPUs. Start with 8-bit CPUs and go to 32-bit CPUs. One type of CPU corresponds to one type of PLC."

"Also, the system ACIS code chip should be unified, and the RAM chip can be configured according to the grade of the PLC."

"Xiao Liu is right. I think input modules, output modules and expansion modules should be standardized."

In the conference room, the technicians were actively discussing, and all the components of YM-PLC were determined one by one.For example, PLC power supply, CPU, memory, input and output modules, extension of a certain block, instruction series, etc., are all set to a unified standard.

Seeing that the members of the YMPLC team basically formed a unified opinion, Xu Zhenming took out the PLC products of Yiming Group within three months and left the meeting room without any problem.

After saying goodbye to He Changlin, he came to the No. 3 plant of Mingxin Manufacturing Company and inspected the installation and debugging of the 0.6-micron chip production line.

Zhang Neojin heard that the boss was coming to inspect, and was already waiting with Wanninggu at the gate of No. 3 factory.

"Xu Dong, the 0.6-micron chip production line has been installed and debugged, and we will start trial production within one week." After the three people met, Zhang Nyjin reported the situation to Xu Zhenming with a smile.

The progress of this project is in line with Xu Zhenming's original plan, but there is no problem.

The only tricky thing is that there will be problems with the storage of silicon ingots.When Wan Ninggu came here, he negotiated and communicated with Zhang Neojin and planned the trial time of self-produced silicon ingots.

"How is your situation there?" Xu Zhenming looked sideways at Wanning Gu beside him after listening to Zhang Nyjin's report.

Wang Ninggu's team is working overtime to install two 8-inch silicon wafer production lines, which were originally planned to be put into operation in June, which can ensure the production demand within the Yiming Group.

However, Huang Li and Wu Tianling's optical fiber project team are also preparing to build a production line near the silicon wafer factory, which may affect the normal operation of the 8-inch silicon wafer production line.

"Xu Dong, Dr. Huang, and Dr. Wu suggested that the silicon wafer factory and the optical fiber preform factory will produce joint production, which will save costs and increase the utilization rate of raw materials. I think this method is better, so I came to negotiate with Mr. Zhang and postpone it. Delivery time for self-produced 8-inch silicon wafers."

Wanning Gu told Xu Zhenming the reason for coming here.

His suggestion is very good. Once it can be realized, it can save a lot of costs for Yiming Group.This is how the internationally planned and operated Goryeo Guosanxin Electronic Silicon Industry Factory.

"Eh? Is there such a scientific plan?" Xu Zhenming couldn't help but become interested.He, Zhang Nyjin, Wanninggu and others hurriedly looked at the 0.6-micron chip production line, and immediately drove toward the Yangtze River embankment, ready to take a look at the engineering site of the silicon wafer factory.

Beside the Yangtze River Levee, on the wasteland north of the Yiming Group Corporation compound, various construction equipment such as pile drivers and excavators are roaring.The construction workers of Honghe Jian'an Company are working to build a large silicon industrial park.

To the south of the construction site, in the factory building of the former Nan'an Textile Group Company, Li Quan led the engineering team. Under the command of the technicians of the Wanningguo team, two 8-inch silicon wafer production lines are being installed.

Xu Zhenming, Wan Ninggu, Zhang Nyjin and others arrived outside the factory where the silicon wafer production line was installed.As soon as they got out of the car, they were stopped by Huang Li and Wu Tianling.

"Xu Dong, you came just right. I suggest building a VAD process optical fiber preform factory near the silicon wafer factory."

"It is best to build a PCVD process optical fiber preform factory. Xu Dong, we need two pilot factories as experimental bases."

Huang Li and Wu Tianling stopped Xu Zhenming and snapped out their thoughts.

They told Xu Zhenming that optical fiber preforms are the most profitable product in the optical cable manufacturing industry, accounting for about 70% of the profit of optical cable products.

There is no such product in China, and it can only be imported from the United States and island countries.Once the island countries and the United States terminate the supply of optical fiber preforms, the optical cable production line of Chaoming Manufacturing Company will immediately cease production.

This is the sorrow of the Chinese people. Every product has no basic raw materials, and foreigners are choking their necks!

"Well, your suggestions are very good. But why do we want to build two pilot plants for the VAD process and the PCVD process?" Xu Zhenming basically accepted Huang Li and Wu Tianling's suggestions, but still had some questions.Is the investment a bit big for a factory that invests in two processes?

Huang Li glanced at Xu Zhenming and introduced solemnly, “Xu Dong, the raw material of optical fiber was originally made of natural quartz. But the cost is relatively high, and now it is changed to synthetic quartz. The synthetic quartz process is divided into two types, one is the in-tube deposition process , Such as the PCVD process; the other is the external deposition process, such as the VAD process. The development trend of these two processes is inconclusive, and we cannot give up, lest we lag behind the world's technological level."

Standing on the side, Wu Tianling also nodded and added the speech of senior sister Huang Li, “Xu Dong, since our Yiming Group is going to take the road of self-development, the optical fiber manufacturing technology must not be out of the world's technological level. Both VAD process and PCVD process should be used. Start and move forward together to avoid the trouble of getting into a bottleneck."

The two of them told Xu Zhenming that if the factories of these two processes were combined with silicon wafer factories, the cost would be much lower.The polysilicon purified in the silicon wafer factory can be used as a raw material to manufacture optical fiber preforms without wasting various chemical reagents.

In this case, Xu Zhenming still agrees with Huang Li and Wu Tianling's opinions.In particular, when he heard that the silicon industry factory of Korea Guosanxin Electronics had this layout, he naturally accepted Huang Li and Wu Tianling's plan.

"Will this layout affect the production schedule of 8-inch silicon ingots?" Xu Zhenming's only concern is whether the silicon wafers can ensure the demand of Mingxin Manufacturing Company.

Nowadays, the market selling price of silicon wafers in the international market has remained high.In case Yiming Group has a problem of insufficient supply of silicon wafers, there are still two problems whether it can buy silicon wafers.

Hearing these words, Wan Ningguo patted his chest and promised: "Xu Dong, our silicon wafer factory will officially reach production by the end of June at the latest, and it will not affect the production plan of Mingxin Manufacturing Company."

With his assurance, Xu Zhenming was more at ease. Accompanied by Wanninggu, Huang Li and Wu Tianling, he began to inspect two 8-inch silicon wafer production lines.

After some inspections, no major hidden dangers were found. Xu Zhenming was about to leave and return to the headquarters of the group company.At this time, Huang Li smiled and suggested: "Xu Dong, can you take a look at the optical cable production line of Chaoming Manufacturing Company?"

The optical cable production lines of Chaoming Manufacturing Company are all imported production equipment from the United States, and are divided into two parts: optical fiber production line and optical cable production line.Currently, the equipment of these two production lines is being installed and debugged, and it is expected to be put into trial production by the end of June.Xu Zhenming happens to be free, so he can go and inspect again.

Thinking of this, he nodded and agreed to Huang Li's request.Soon, Xu Zhenming, Huang Li and Wu Tianling have arrived in the No. 17 factory building of Chaoming Manufacturing Company.

This No. 17 plant is still a dust-free workshop for the installation of automated optical fiber production lines.

The optical fiber production line is composed of optical fiber preform smelting and surface treatment system, optical fiber drawing and primary coating system, optical fiber tension screening and coloring system, optical fiber inspection system, and optical fiber secondary coating system.

The function of this production line is to draw the optical fiber preform into a slender glass filament, and then spray and color the glass filament.It looks simple, but it's actually more difficult.There is no similar advanced equipment in China.

Therefore, Xu Zhenming specially asked all team members of Yiming Group's technical department to participate in the installation and commissioning of this production line.

At this moment, the workshop is very busy.The team members of Zheng Cheng, Sun Chao and Wang Zhizhong, under the leadership of American engineers, are busy.

"NO! NO...NO! OHMGD!" At this moment, a foreign engineer yelled in horror.

I saw that a worker under Xiao Guohong didn't pay attention and collided during hoisting, smashing the control cabinet of the optical fiber drawing lathe.

The optical fiber production line has a high degree of automation, and all control programs are in the computer board of the control cabinet.In this case, the optical fiber drawing lathe must not be used, and a major operation is required for maintenance.

The American engineer immediately took out his camera to take pictures of the scene and shouted to Xiao Guohong, "This equipment was damaged by your company, and we are not responsible for the warranty."

When Xiao Guohong heard this, his face became pale when he brushed it, and he quickly asked the American engineer, "How much do we need to pay for maintenance?"

"200,000 U.S. dollars. It wouldn't be possible without 200,000 U.S. dollars!" The engineer stretched out two fingers and shook Xiao Guohong.

The value of 200,000 US dollars is more than 1.7 million yuan. In this collision, Chaoming Manufacturing Company suffered a big loss.

Xiao Guohong also knew that he had caused a catastrophe, and the cold sweat on his forehead broke.He quickly took out his cell phone and dialed Xu Zhenming's cell phone, ready to report the situation to Xu Zhenming.

Xu Zhenming was near the door of the workshop and saw all the passing just now.He picked up the phone and waved to Xiao Guohong, signalling Xiao Guohong to invite the American engineer to the office to negotiate.
