Domestic car manufacturing is weak, what does it have to do with our land tanks?

After calming down for a while,

Lu Yan drew the lottery again.

“Congratulations to the host for obtaining the manufacturing technology of”polymer special aviation glass” and the complete production line equipment drawings”

【Polymer special aviation glass: This special glass material has polymer and high density characteristics, extremely high internal purity, 99% light transmittance, can withstand extreme high temperatures and extreme cold, and has a hardness more than three times that of current aviation special glass. The single layer thickness is 1cm, which can defend against ordinary pistol bullets, and the double layer can resist armor-piercing bullets and explosion-proof! 】

Result.

The”black technology” drawn out.

It surprised Lu Yan again!

“Single layer can defend against ordinary bullets, double layer can defend against armor-piercing bullets and explosion-proof……”

Lu Yan muttered in a daze.

What the hell is this?

Even if China’s glass manufacturing technology is at the world’s top level,

I can’t guarantee that a 2cm thick double-layer special glass can withstand armor-piercing bullets?

Even the special glass on the front windshield of the J-20 can’t achieve this strength!!

Outrageous!!

Is this thing really used to make ordinary cars? ?

Lu Yan was a little���I dare to think about it.

How hard must the car glass be made?

“Host, please rest assured that the technology produced by the system is in line with the needs of car manufacturing. The greatest luxury of a car is safety. If it does not have top-level safety, it cannot be called luxury.”

As if it had sensed what Lu Yan was thinking.

The voice of the system suddenly said.

Lu Yan suddenly didn’t know what to say.

This is indeed right.

Expensive luxury cars may have various features, but they must have one thing in common, that is, the materials are quite sufficient and absolutely safe!!

Rich people are not fools. For example, the executive-level luxury cars that receive important people regard safety design as the first priority.

Extreme safety is itself a kind of invisible luxury.

It’s just that the two black technologies of the system are really abstract.

Are you sure it’s not a super military system?

“do not care……”

“Who says aerospace technology can’t be used to build cars? ?”

Lu Yan suddenly felt a different kind of excitement in his heart, and he drew three more times in a row!

“Congratulations to the host for obtaining the manufacturing technology of”Aerospace Special Aluminum Alloy” and the complete production line equipment drawings”

“Congratulations to the host for obtaining the manufacturing technology of”Nanoscale Biological Circulation Filtration System” and the complete production line equipment drawings”

“Congratulations to the host for obtaining the manufacturing technology of the ‘super dmi hybrid system’ and the complete production line equipment drawings”

……

【Aviation special aluminum alloy: has extremely high strength, hardness, toughness, and fatigue resistance, and its strength is more than twice that of the current aviation seven-series aluminum alloy.……】

【Nano-scale biological circulation filtration system: Using nano-material filter element, it can filter air particles smaller than 0.01, with a filtration efficiency of up to 99.99%, filtering range includes pollen, bacteria, dust, poison gas, etc.……】

【Super DMI hybrid system: A super hybrid architecture with the motor as the main and the engine as the auxiliary, which realizes the use of electricity at low and medium speeds and oil at high-speed cruising. It has a vector power control function, which can always keep the power in the most efficient driving range, maximizing the endurance and vehicle power requirements……】

The description of these black technologies.

Any one of them can cause a sensation!

Lu Yan was still carefully studying the details of these black technologies.

But soon.

The sudden sound of the system gave Lu Yan another surprise.

“Ding, it is detected that the host has drawn five times and automatically received the novice gift package. Please confirm whether to receive it?”

Lu Yan said without hesitation:

“Get it!!”

System:

“Congratulations to the host for winning a ‘10,000-ton super-large intelligent die-casting machine’, and congratulations to the host for winning ‘production line materialization props*5’！”

【10,000-ton ultra-large intelligent die-casting machine: It adopts semi-solid die-casting technology, vacuum technology, high-pressure spot cooling technology, and local extrusion technology. It can simplify dozens of complex processes such as riveting, stamping, welding, forging, etc., and can die-cast the world’s most accurate and strongest one-piece white body.】

【Production line materialization props: After use, any technical drawing can be materialized into a complete production line equipment (Note: specifically the scale of a general car production line)】

……

“Insane!!”

Seeing the”10,000-ton super-large die-casting machine” on the stage, Lu Yan took a deep breath.

In the current car manufacturing market, even the top car manufacturers use super-large die-casting machines of only 8,800 tons.

Here we have to talk about the role of large die-casting machines.

This thing is almost a”magic weapon” for mass production of cars!!

In the early years, the body of a car was made of thousands of parts, spliced together by riveting, stamping, welding, and forging.

These sophisticated and complex manufacturing processes alone require huge costs and labor.

The greatness of the die-casting machine lies in that after design The design can directly die-cast thousands of parts into one piece, simplifying the complexity and directly die-casting a complete body frame.

The benefits of this are also obvious.

Not only does it greatly improve the mechanical efficiency, but the body made by the top die-casting machine, whether in rigidity or toughness, far exceeds ordinary assembly and welding.

Therefore.

Today’s high-end cars, the body frame is made of aluminum alloy one-piece die-casting.

Even the chassis parts, the more aluminum alloy materials are used, the better, and pure aluminum alloy chassis are only available in high-end cars.

Because aluminum alloy is light enough, with high hardness and high toughness, and will not rust……

“The body and chassis are made of aviation special aluminum alloy, the four doors and front and rear anti-collision beams are made of aviation special steel, and the front and rear windshields, four door glasses and sunroof are made of polymer special aviation glass.……”

Lu Yan has slowly come up with a plan in his mind.

If the black technology used in this car is built, it will not only bring the current Hongqi back to life, but it will even cause a big earthquake in the entire car manufacturing industry!!
