The black technology empire started with a debt of one billion

Chapter 448 463: Actually they are not playing with mud

When Guo Kezun saw Cao Mang's refusal to make PC products, he stopped pushing.

In fact, it’s not that Cao Mang can’t make PC products, but he just needs to use his own CPU to do so. In this way, he will be hostile to the two companies, and he will face a lot of pressure at that time. Cao Mang does not want to be an enemy of them in the short term. .

After the NIL nanoimprint technology comes out, Cao Mang has nothing to worry about.

NIL nanoimprint technology can not only manufacture single-digit nano-process chips, but also make chips at one-fifth of the price.

NIL nanoimprint technology is a crushing trend for EUV lithography machines.

Deep Blue Technology does not make PC chips or even PC products, which is very good news for the two companies.

Then the two chatted with Cao Mang for an hour before leaving.

After the two left, Cao Mang came to Automobile Laboratory No. 1 on the first floor of Block D of the laboratory.

As soon as I entered the door, I saw several engineers playing with mud.

If someone who doesn't understand cars comes here, they will definitely complain. I invited you here to build cars, but you are here playing in the mud?

They weren't actually playing in the mud, they were making clay models of cars.

Many people know that the design concept of a new car comes from the concept car, so how is the concept car designed?In fact, after the designer draws the manuscript, the clay model making is a necessary link.

The clay model can turn a flat manuscript into a three-dimensional form, presenting a very realistic three-dimensional car shape, which will be of great help to the design of future mass-produced models.

It is more convenient to determine the plan or further refine the car styling design based on the clay model. For example, whether the curved surface should be bulging outward or inward, and whether the curve should be adjusted up one millimeter or down. Such a process is difficult to do. Implemented on floor plan.

Clay is the main material for making models, but it is not mud. The material does not contain water or soil. It is similar to ordinary plasticine, but the requirements are higher. The main components of the clay are 62% talcum powder and 30% Vaseline. , 8% industrial wax, this material has strong plasticity and can be used for repeated cutting.

However, at present, we can only rely on imports for stable and reliable quality clay, mainly Germanic clay and footbath chicken clay. However, the price is relatively high. Usually, the cost of a 1:1 clay model may be around 20 yuan.

Because oil sludge is relatively expensive, it is wasteful to use it for the interior of the car body. The initial embryo of the model is usually cut and bonded with foamed plastic, mainly to present the basic shape of the model.

When making the initial embryo, it is usually about 3cm smaller than the outer shape of the car body (reserve the thickness of the mud), and minimize the protruding sharp corners to facilitate the later polishing and scraping of the mud.

After the initial embryo is completed, the clay model begins to be made, which is roughly divided into several steps: filling the clay, rough scraping the clay, fine scraping the clay, applying the film, and spraying the paint. The lights, tires and other components are finally installed.

汽车油泥模型有许多规格，通常有1：1、1：4、1：5等比例。其制作方法也略有不同，一般来说设计前期采用小比例的模型，后期采用1：1的模型。

A full-scale model refers to a model with a 1:1 ratio, which is the same size as the real car. The contour curve and size of the model are made according to strict requirements.

When making a full-size model, designers will only compare and modify the details of the body surface.

The full-scale clay model is a highly simulated product. The wheels generally use real rims and real tires. In addition, other accessories on the car body, such as lights, logos, and window glass, will be placed in their respective positions. position.

In order to make every detail of the car more rigorous, some models will also have a metal film or spray paint on the surface to achieve a very similar level to the real car, making it easier to make adjustments and modifications more intuitively.

The shape of a car is relatively complex and is composed of many smooth curved surfaces. Making a clay model of a car requires repeated deliberation and modification. Therefore, every perfect clay model of a car is like a unique work of art. They are all the result of the hard work of designers.

Clay model is very important in the process of car design. No matter how good a sketch is, it is only a sketch, if it cannot be converted into a 3D solid model.

Such a sketch also loses the meaning of the sketch.

A good clay artist can transfer the aura of the sketch to the model to make it a reality.

Many people may wonder, now that computer simulation software is so advanced, can't the exterior design of a car be completely simulated by a computer?Why waste time and effort to make clay models?
In fact, the modern body design process is a method between traditional body design and computer-aided body design, the so-called "profiling method".

In the profiling method, the clay model is still used for its authenticity. The process of rendering renderings and clay model production is retained, and computer-aided design methods are used to replace the main drawing board production and other steps in the traditional car body method. Use a computer to complete the mathematical model as a production preparation document.

In addition, because the car model is an intuitive three-dimensional entity, it is also the most visually impactful display method.Compared with flat manuscripts or computer three-dimensional data, clay models can obviously better express the designer's ideas.

Of course, with the emergence of mature automobile [-]D design software, it is much simpler to make virtual automobile digital models in computers, and then process them through machine tools, which greatly omits part of the work that had to be done by modelers before. It also saves some rough and labor-intensive traditional skills in the pre-production work of the modeler.

The biggest difference from computers is that human thinking has infinite creativity, and models made by hand are more artistic.Handmade clay modeling represents the finest sculptural traditions in the world, depicting the purest surfaces of design.

For almost all world-renowned automobile companies, making clay models is a very important part of the design process.

In addition, when testing the vehicle dynamics, the vehicle sludge model is also used for testing.

For example, the most traditional wind tunnel test.

Wind tunnel experiments can simulate air resistance, noise, and thermodynamic conditions encountered in various driving environments to test the safety and handling stability of prototype cars and minimize the power loss of the car while driving.

Once data anomalies are discovered during wind tunnel testing, engineers can carry out engineering development and design optimization.

Automobile designer Deng Zhennan stood aside and directed several engineers to model the 1:1 model.

At present, the frame of this 1:1 car model has come out, and it can be tested only after trimming the appearance.

But Cao Mang didn't come here to look at this 1:1 model. What Cao Mang wanted to see was another 1:10 model.

At this time, an engineer saw Cao Mang.

"Mr. Cao." Tong Changqing greeted Cao Mang immediately when he saw him.

Several people in the laboratory turned their heads to look in Cao Mang's direction immediately after hearing the voice.

"You continue to work." Deng Zhennan said to several people and walked towards Cao Mang.

"Where is the model?" Cao Mang asked.

"Mr. Cao, please come with me." Deng Zhennan said with a serious smile.

Deng Zhennan is good at everything but keeps a straight face all day long, maybe because he doesn't know how to express his emotions.

Cao Mang followed Deng Zhennan to a workbench.

There is a 1:10 car model on the workbench. The appearance of the car is very similar to the Tesla Maodou 3. The general appearance was designed by Cao Mang based on the Maodou 3. The difference between this car and the Maodou 3 is the panoramic sunroof.

The panoramic sunroof is a very stupid design. You will know how stupid this design is on hot days. The temperature inside the car is at least much higher than that of other cars.

If you put your car in an open-air parking lot, you need to turn on the air conditioner for at least half an hour before you can take a seat.

As for edamame 3?

Tesla has not released Edamame 3 at this time.

特斯拉Model 3是016年4月1日11点30分发布的。

Cao Mang took out the dark blue MAX from his pocket and took a video of the car model from multiple angles.

"When will the dynamic test be performed?" Cao Mang asked after putting away the Deep Blue MAX.

"It will probably take another week." Deng Zhennan said.

"You guys did a great job." Cao Mang nodded in satisfaction.

"Mr. Cao, your integrated concept is really great, especially the integrated die-casting method, which not only reduces the weight of the car body by 18%, but also saves nearly 15% of the manufacturing cost. The number of body parts has also increased from 227 to 57. Reduced to [-], the assembly speed is at least three times the original.

If Lijin could produce larger-tonnage integrated die-casting, reducing the number of car bodies to less than 30 would not be a problem at all.

By then, the manufacturing cost of a car is expected to drop to about 22%. "Deng Zhennan said.

“This kind of integrated die-casting is not without its drawbacks, which means that the maintenance cost will increase significantly. Once an accident occurs, the user has to replace the entire body, which is not so user-friendly.

So we now have just the right number of parts, so if something goes wrong we don’t need to replace the entire vehicle.

When making products, we can’t just think about making money for ourselves. We must also consider our customers. In addition to providing customers with high-quality products, we must also provide customers with cheap maintenance services. Why has Santana become the first choice for taxis?
Just because the maintenance cost of Santana is the lowest among all cars.

It is not easy for users to spend hundreds of thousands to buy a car. If something goes wrong, it will cost hundreds of thousands to repair. Which user can accept such a car.

Although users will be compensated by the insurance company if an accident occurs after purchasing insurance, the insurance company is not a good person. Faced with such a situation, they will definitely increase the premium. Once the premium goes up, electric vehicles will not be as affordable as everyone imagines.

At that time, it will definitely have a certain impact on sales. "Cao Mang said with a smile.

In the previous life, Tesla used this method to build cars, but the entire car body had to be replaced in the event of a collision. The repair cost for a car worth 28 yuan after an accident was as high as 20 yuan.

Netizens joked that the Model Y is equivalent to changing a car.

In fact, netizens' ridicule about Tesla's sky-high maintenance fees originated from an accidental collision "accident" in February 22.At that time, a Model Y owner with a Jiangsu license plate hit a corner while reversing, causing damage to the rear body of the vehicle. Tesla claims personnel told him, "The rear shock absorber package was damaged, and the repair cost was nearly 2 yuan."

The owner of the car then complained, "The new car is only 28 yuan, so it is better to scrap it." This also triggered netizens' complaints about Tesla Model Y that "scratching is equivalent to changing a car".

As for the sky-high insurance premiums for electric vehicles, countless car owners have complained about it.

On December 2021, 12, some netizens exposed a "sky-high price" insurance policy for Tesla Model Y.

The policy shows that the commercial insurance price of the 2021 Tesla TSL6480BEVBA5 pure electric multi-purpose passenger vehicle (Tesla Model Y long-endurance version) is 14235.02 yuan, and the compulsory traffic insurance is 950 yuan. The total insurance premium of the car reaches 15485.02 yuan per year.

In a car insurance estimation calculator, the estimated commercial insurance price of a Volvo XC60 with a price of about 90 yuan is 15915 yuan per year.

If it were replaced by Great Wall's Haval H5, the annual premium would only be more than 4000 yuan.

This 1 premium is enough for car owners to fill up the gas many times. These problems also make many people shy away from electric vehicles.

Cao Mang left the No. 1 Automobile Laboratory and went to the No. 2 Laboratory next door.

The responsibility of Laboratory No. 1 is car exterior design, and the responsibility of Laboratory No. 2 is car chassis design.

As soon as Cao Mang entered the laboratory, he saw the staff installing batteries on the chassis of the car.

The integrated chassis of Shenlan Automobile adopts the CTC battery solution. The integrated technology of CTC battery chassis is to integrate the battery into the chassis and make it a part of the vehicle chassis. It further deepens the integration of the battery system with the electric vehicle power system and chassis. Reduce the number of parts, save space, improve structural efficiency, significantly reduce vehicle weight, and increase battery life.

However, the battery installation method of the deep blue car integrated chassis is different from other brands.

Other brands of batteries use welding to connect the batteries in series, but Deep Blue Technology uses .
I won’t spoil the specific method used.

When the car is released, everyone will know what kind of method Deep Blue Technology adopts.

Chang Jianbin, who was overseeing the work, was the first to notice Cao Mang's arrival.

"Mr. Cao." Chang Jianbin said with a smile.

After Chang Jianbin said hello, he walked towards Cao Mang.

"How is the progress of the chassis completed?" Cao Mang asked.

"Basically, it has been completed. After the battery is installed, it can be tested. After replacing it with 4680, the capacity has increased a lot. The capacity has increased from 58KW to 85KW, and the estimated battery life has increased from 460 kilometers to 780 kilometers." Chang Jianbin Said.

In addition to the graphene battery, the reason why the deep blue car has such a great battery life is also due to the graphene-based enhanced copper.

This graphene-based enhanced copper is actually not a very powerful thing.

This thing is similar to the vinyl carbon aluminum alloy used in the dark blue car body.

It is to add a little graphene and other materials to the copper, but its synthesis method is a bit complicated, but Deep Blue Technology has achieved mass production of this material.

The ordinary version of Maodou 3 has a battery life of only 405 kilometers, and the deep blue car has a battery life of 780 kilometers. This performance can definitely kill Tesla in seconds.

The integrated chassis of Shenlan Automobile is 4.5 meters long and the wheelbase is 2.9 meters, which has reached the standard of a B-class car.

The drive mode adopts the standard rear drive drive.

Because it is the beggar version, the battery capacity is only 85KW. If it is the deluxe version, it can be 115KW. The deluxe version still uses four-wheel drive. Because of limited time, they are only making the chassis of the beggar version.

I believe that after the beggar version of the chassis is made, it won’t be long before they can create a luxury version of the chassis.
