The door of the courtyard house has been welded dead

"I wonder why bulletproof vests are so cheap. A small factory can produce nearly a million tons a year?"

Holding the list of Lunan Aluminum Plant in his hand, Li Feng's eyes popped out regarding the plant's output, and he was too tired to complain.

Millions of tons of alumina, it is not related to the industrial base of steel, it is an inorganic substance, its function is not as extensive as that of steel.

In this era, the output of this thing is almost approaching the steel output of Shijingshan Iron and Steel Plant. The weight of a bulletproof insert is only a few kilograms. In this era of backward production capacity, the output of a small factory is equivalent to producing 200,000 to 300,000 bulletproof inserts a year.

With such terrifying production capacity, it is not surprising that you can buy a bulletproof vest with a high level of bulletproofness for one or two hundred yuan, or two or three hundred yuan.

Li Feng felt that he could lie down from now on. In his impression, the bulletproof insert seemed to be made of aluminum, but he really couldn't recall this memory. At the switch factory, he learned that they used alumina. Now everything matched.

But Li Feng never expected that the production of this stuff would be so shocking. It required dozens of tons of this stuff, and the factory was not short of it at all. After getting the order, Li Feng felt that he really had less, like plucking a hair from a nine-headed ox.

"Take it easy, take it easy, hehe~!"

Picking up the draft paper on the table, Li Feng began to draw the three-view drawing of the bulletproof insert. After all, this thing is simple, like a small shield, it just needs to maintain a slight curvature and fit the body.

Of course, in addition to the bulletproof plate, Li Feng also included a diagram of the tactical vest.

Li Feng has seen the current tactical vests. They are too simple in design and have very simple functions. They have magazine pockets on both sides, grenade pockets on the back, and a quick-release button at the navel position on the front.

It is so simple that it cannot be called a tactical vest. It can only be called a carrying device. Because in order to carry these combat equipment, they need to be fixed on the body, so this thing came into being.

Modern tactical vests are generally of the strap type, worn on the head, opened and closed at the waist on the sides, fastened with Velcro, with four magazine pockets on the chest and a grenade pocket at the waist.

The biggest difference is that there is a reserved pocket on the back of the chest, where the bulletproof plate can be inserted when needed, which can be single-sided or double-sided.

"It's all about being handsome~!"

Li Feng lit a cigarette, looked at the impressive design drawing, and nodded self-satisfiedly.

In the previous life, I crossed the river by feeling the eagle's back. In this life, no matter what, I have to let the eagle cross the river by feeling the rabbit's back.

After finishing the two drafts, Li Feng still felt a little unsatisfied. The level 6 armor in Tarkov also comes with shoulder and crotch guards.

Considering that the troops want something sturdy, cheap and durable, the one above designed for the troops is just right. The plug-in plate is not used during daily training, but is inserted during combat.

As for the Investigation Department, they are more meticulous and have a more comprehensive protection design. When a fully-armored rogue soldier engages in close-range shooting, any lurking enemy spy who sees them will fall asleep immediately.

These are still small numbers. With so many public security officers and border guards across the country, this alone is enough to support the steel mills for many years.

When the big camel comes waving money to buy firecrackers, as long as it can catch the light of the export, the steel rolling mill can even survive the most difficult period of the state-owned factories.

The main factory is responsible for military production, the branch factory is responsible for civilian steel, and the project department is responsible for building houses and infrastructure.

"It's settled~!"

Delightfully, she put the design drawings into the safe. Unfortunately, she couldn't register a patent now. Otherwise, Li Feng would have to collect patent fees from all over the world.

"Dingling bell~!"

After finishing his work and pouring a cup of tea, Li Feng, who had not yet had time to slack off, casually picked up the phone on the table.

"what?"

"Okay, okay, I got it. Notify Lu Lei and Feng Zhigang to come upstairs for the meeting, fourth floor~!"

After hanging up the phone, Li Feng's face was a little uncertain. The General Logistics Department called, but did not call him. She went directly to the secretary's office and informed Li Feng to let the technical department prepare for a trip in the afternoon. Li Feng didn't know what to prepare, but he guessed a little. The General Logistics Department probably didn't know that he had already obtained a porcelain technician and production line through other channels.

Then notifying myself to prepare should have nothing to do with bulletproof armor. Currently, there is only one thing that the General Logistics Department can take a fancy to.

That is the third-generation grille armor that has undergone preliminary testing. Although its weight is slightly higher than expected, it is limited by the material and there is no way to make major improvements for the time being.

To achieve better protection, either the thickness of the grille blades must be increased to increase the impact resistance, which will undoubtedly be heavier.

The third generation has gone through two generations of iterations. Considering the trade-off of weight, it is the cheapest and most cost-effective solution.

If it is too heavy, it will affect the performance, armor fuel consumption, and maximum driving distance. If it is too light, it will affect the protection effect. At present, the best solution is to use special alloys, which will undoubtedly cost much more.

Standing up and sorting out the relevant materials, Li Feng was the first to walk into the meeting room.

After a while, after being notified by the secretarial office, Director Feng from the cold rolling workshop and Chief Lu from the technical department came upstairs together.

"I just received an order from the General Logistics Department. We have to go out this afternoon. It's just the three of us. No need to bring anyone else. I think it's related to surveying and mapping. Be mentally prepared~!"

"Is it really done?"

Chief Lu couldn't help himself and asked with joy. He probably had guessed it on the way here with Director Feng.

"Tsk, the superiors haven't arranged production yet, so don't ask too many questions. I called you here because once the workshop officially arranges production, this project will involve the army. I emphasize again, keep it confidential~!"

"First, the production volume. Director Feng, you are in the workshop. Please give me an accurate estimate of the production volume. How many square meters of grilles can be produced in a month?"

Li Feng casually took out his notebook. Whether he went to the army to survey tanks and armored vehicles, or went to the General Logistics Department, people would ask about production, and he, as the factory director, had to have an idea in his mind.

"This, production, how much steel is delivered to our cold rolling workshop, how much can be rolled out, mainly depends on the welders~!"

Compared to Chief Lu's excitement, Director Feng had a bitter smile. Once the steel materials were delivered and the rolling molds were replaced, rolling could begin directly. Depending on the required size, the machines could be operated 24 hours a day, as long as there were people at the place where the materials were delivered and transported.

A small steel bar two centimeters wide is fed into the feed port here and is formed when it comes out of the discharge port over there. It is extremely simple.

The difficulty lies in the welding workshop. They had to temporarily weld a few experimental grille armors, and several masters were borrowed from there to complete it. Once the production started, Director Feng was not worried about himself, but about the welding workshop. After all, people are not machines.

"Welding workshop, if we stop the current work and start welding grille armor, how much do you think we can produce in a month?"

"Then I guess not... The joints need to be fully welded. There are more than 70 welds per square meter. One person can weld 20 to 30 square meters a day, right?"

Seeing Li Feng glaring at him, Director Feng pursed his lips and stopped talking. After all, when it was first being made, the factory director had given him a drawing, and it was he and Section Chief Lu who worked together to come up with it based on the drawing and requirements.

"Almost. Welding too much will hurt your eyes. No, just 16 or 17 square meters. I will try to weld a whole set by myself in one day~!"

Section Chief Lu thought about it, and when he saw that Li Feng was really going to write thirty, he squinted his eyes and thought it would be better to write lower, step by step. If he couldn't meet the requirement right from the start, he would be doomed.

"Okay, let's set a lower price first. Then I'll move on to the second point. It's still the same old thing the factory has been talking about recently. Quality, we have to control it?"

"Military supplies, you two both know what this grille is protecting against. If there is any desoldering, or the welding position is not firm, or even falls off, I will find Chief Lu. You have to supervise this."

"Okay, I'll assign more technicians to supervise each welding point. However, Secretary Li, we have to get more people into the technical department this year~!"

Faced with the burden thrown by Li Feng, Section Chief Lu smiled bitterly and could only nod in approval. The three of them were now in the same boat, and they would prosper together and suffer together.

"Don't worry about that. I arranged for someone to do it before the New Year, and the school has been contacted~!" (End of this chapter)
