The people of the Celestial Empire often do not pay special attention to the interior of the first car, but Jiang Hui knows that these things will really affect the reputation.

In the past, some brands had excessive VOC in their interiors, the smell was very strong, and they still stinked after a year or two, or the plastic of various decorative parts made consumers no longer consider the same brand when buying a second car or replacing a vehicle.

On the contrary, some companies that have done a better job in interior details have more repeat customers.

Many consumers bought the entry-level model of this brand for the first car, and directly bought the high-end model of this brand when they bought the second car.

Although the current Celestial Dynasty people still pay the most attention to the appearance and price of buying cars, but the world's largest market will eventually mature slowly, Jiang Hui hopes that Guanghui Automobile can become a century-old enterprise, rather than a model on the market, and the hot sales will decline rapidly after two years.

"The suppliers of purchased parts for this model have been decided, right?" Jiang Hui asked his concerns while sitting in the car.

"At the end of last year, we have made a formal decision and notified all suppliers to open the mold and prepare the parts," Kato quickly replied.

Notifying suppliers to open the mold is a very important time node, and Jiang Hui has this concept quite well.

Most parts suppliers need to invest relatively little money before opening the mold. For example, the drawings of the various stamping parts used in the welding workshop are designed by the Guanghui Automobile Research Center, and what the supplier needs to do in the early stage is nothing more than to quote to the purchasing department of Guanghui Automobile, and at the same time review their own production capacity planning to verify whether the parts can be produced by themselves.

In fact, these jobs don't cost much money.

But that's not the case when Korn Ferry decides that the parts are made by a supplier and officially notifies them to open the mold.

At this time, the real money is about to be spent.

If the mold is made by the supplier itself, then they need to start the formal mold design, purchase materials and some accessories, which all cost money.

If the mold is made by the supplier to find a special mold manufacturer, it is necessary to pay a sum of money to the mold manufacturer in advance, and sign a formal contract with others, and then cancel it, the cost will be large.

Therefore, it is very important and cautious to notify the supplier to open the mold.

However, at this time, it often means that the basic development of the model has been basically completed, and the rest is mainly a matter of verification and the factory to promote mass production.

"What is the state of our supplier system and how stable is it?"

Jiang Hui asked another question that is important for auto companies.

There are more than 10,000 parts in the car, and no matter which automobile company it is, it is impossible to make all the parts by itself, which is unrealistic and uneconomical.

Professional things are left to professional people to do, and the same is true for parts.

It's just that the relationship between this professional organization and the main engine factory is sometimes very important.

Don't look at the Celestial Empire, the automotive industry is about to surpass the United States today to become the world's largest market, but the core parts manufacturers in the automotive industry are all foreign-funded enterprises.

Just take a look at the ranking of the top 100 auto parts every year.

Bosch, Denso, Magna, Continental, Delphi, Aisin Seiki, Johnson Controls, Valeo, Lear, ZF, TRW, BASF, Yazaki, Sumitomo, Toyota Boshoku, Dana, JTEKT, Hitachi, Calsonic Kansei, MAHLE, Autoliv, Benteler......

In the entire list, you won't find a single enterprise that is a Celestial Empire.

Domestic automobile companies, regardless of whether they are joint venture brands or independent brands, there is no company that does not use the products of these companies.

In particular, the parts related to the body electronic system and safety system are basically used by foreign brands.

If you really want to talk about the difference, it's nothing more than that you use a Bosch one, I use a Denso one, and the brands are different.

"Mr. Jiang, after all, our Guanghui Automobile is a newly established company, although the number of our model planning is as high as 100,000 units per year, but not every supplier is very confident in us", Pi Wei took over Jiang Hui's question a little embarrassed.

"Some suppliers are not willing to cooperate with us?", Jiang Hui said with a frown.

"There is no one who says not to cooperate, and generally as a supplier, it will not be so direct. But from their quotations, we can see that some suppliers have no sincerity at all. For example, when we asked Denso, Delphi, and Valeo, they all quoted prices, but Denso's price was twice as high as Delphi's, and it was almost 1,000 yuan more expensive, so there was no sincerity at all," said Pi Wei.

Although Jiang Hui likes that all the parts of Guanghui Automobile are purchased by domestic private enterprises, the auto parts companies of the Celestial Empire are indeed not so competitive.

In addition to some parts with relatively low technical content such as stamping and injection molding, private enterprises that can basically meet the requirements can be found in China, and other parts are much more difficult.

For example, things like car air conditioners, don't look at domestic home appliance companies such as Gree and Midea that air conditioners are doing very well, but car air conditioners and household air conditioners are completely different things.

People don't even have the idea of getting involved.

Although the refrigeration principle of car air conditioning and household air conditioning that we are familiar with is the same.

It is based on the principle that R12 or R134a is compressed and released, and the volume expands sharply at the moment, so it absorbs a large amount of heat energy

But car air conditioning, refrigeration and heating are separate systems!

And the home one is a system!

Household air conditioners generally use mechanical compression refrigeration devices, and their basic components are four: compressor, evaporator, condenser and throttling device, which are interconnected, which is filled with refrigerant.

The compressor acts like a galloping heart to make the refrigerant flow in the air conditioner like blood, so as to regulate the temperature of the room.

The automotive air conditioner is generally composed of compressor, electronically controlled clutch, condenser, evaporator, expansion valve, liquid storage dryer, pipeline, condensing fan, vacuum solenoid valve, idle device and control system.

The structure is very different from that of a home air conditioner.

The most important thing is that the car air conditioner is a mobile vehicle-mounted air conditioning device, it is compared with the fixed air conditioning system, the dynamic conditions are worse, with the flutter of the car, the refrigerant of the air conditioning system is more likely to leak than the fixed type, the repair and maintenance of the air conditioning system is also more frequent than the fixed type, the air conditioning system in the air conditioning device often sucks in the dust when inhaling fresh air, blocks the filter screen and the evaporator, and often releases the refrigerant into the atmosphere during the cleaning process.
