I hope that the core power system inside is not the same inferior thing for cutting corners.

Ye Qing, who is paying attention to the live broadcast of Weibo, has an anger that wants to swear.

Memory foam is a good source of purchase from the Internet, but Ye Qing is black and will not do anything like this.

The profit of the mechanical engineering chair is already enough. If you really want to save the insignificant tens of dollars, Ye Qing can replace the leather skin with artificial leather, or the PU leather that most of the seats currently use.

The rest of the money is more than a sponge, and there is no way to recruit people.

Among the memory foams he purchased, latex was indeed added, and the ratio was quite large.

However, the latex component is added to the memory foam to simulate the softness of the human body. The rebound speed is indeed slow, and the comfort level is unmatched by ordinary sponges, and the service life is longer.

The more latex is added, the more expensive it is. This is common sense.

How many thousands of latex products are used, if it is cheaper than a sponge, isn't that funny?

It is even more ridiculous to have an allergy to direct skin contact.

The things that contain latex products are everywhere in life, and there is no one who is allergic. The appearance of the mechanical engineering chair is also covered with genuine leather, which is not accessible to people.

These things Ye Qing understand, but those onlookers do not understand.

The big V, called the mechanical pioneer, has more than two million fans. The content in Weibo is related to the mechanical products in life, and many of the reviews are professional.

The popularity that has accumulated for a long time has given him a lot of supporters, and netizens are mostly convinced of his words.

So when the picture came out, the following comment suddenly became a condemnation of the merchant's black heart, saying that the 80,000 seat would actually cut corners on this detail.

[Do not know if you don’t know it, it’s a shock. The first mover is good, after a lot of products have been unpacked, they are all inconspicuous flower racks. I did not expect this product to be even worse, even the sponges are reluctant to purchase imported goods. 】

[Yeah, the price of the seat has been expensive to the price of a domestic car, why not buy high-quality memory foam imported from the business? 】

[Imported DuPont company memory sponge can not use much money, my girlfriend bought a memory pillow from abroad, but also more than 400. 】

Comments one by one brush, but the vast majority are criticized the mechanical engineering chair business, why use domestically produced inferior sponge instead of imported DuPont high-end goods.

After more than ten minutes, several exteriors were removed from the ground, revealing only the picture of the mechanical engineering chair inside the silver-white aluminum alloy case. It was under his instigation that completely ignited the anger of the audience.

The titles of these pictures are called - [Amazing welding method! 】

Two of the pictures are partially enlarged, and the high-definition picture is a detailed view of the welded part of the aluminum alloy casing of the mechanical engineering chair.

This is two high-level workers who have been welding for even 20 years. They must also sigh with the neat welding technique.

However, the text of the mechanical pioneer first explained that Ye Qingqi’s fire was fierce.

The aluminum alloy casing is designed to protect the complex mechanical structure inside, and in order to pursue a smooth feeling, some places use welding.

The mechanical structure inside, there is no welding place at all, all of which are composed of integrated parts.

The machine pioneer said: "If the sponge is just an exterior, even if the quality is worse, it will not hinder personal safety. Then the welding method of this mechanical engineering chair is definitely a safety hazard for consumers in order to save costs. Ignore it."

“With such a complicated mechanical engineering chair, the merchant chose to manually weld the aluminum alloy in order to save costs.”

“Although I have to admit that the welding workers who are invited by the merchants are very skilled and the appearance of the welding is very beautiful. But this still cannot be concealed. It is the fact of manual welding.”

The mechanical forerunner then updated two pictures, both of which were an aluminum alloy container.

However, on the base below the container, their welds are identified by red circles. One is hand soldered and the other is mechanical automatic soldering.

There are obvious differences in the welds of the two figures. This difference is not technical, but the appearance.

Manual welding, because the welder's model and torch tip specifications are different from the mechanical automatic welding model specifications, the welded welds have a natural appearance.

The seats are hand-welded by the monsters and are not the same as the mechanical automatic welding.

The insider can certainly see it at a glance, but because it is a layman, it can be seen at a glance that the manual welding technology of the mechanical engineering chair has reached an artistic height, and the welding quality is only stronger than the mechanical one. Comparison.

If the mechanically advanced profession is really a senior mechanical engineer, then he can't understand the welds, which is representative of the artistic height.

He is he who deliberately avoided this, and chose to start using the knowledge that laymen seem to make sense, and popularize the shortcomings of manual welding to the audience.

"We all know that manual welding is caused by the shaking of the hand, the problem of pause, and the problem of the naked eye. In welding, it will inevitably cause the following shortcomings."

“The depth of the welding is different: the weld is too thick, and in some places the weld is too shallow, which causes the strength of the material to drop.”

“The number of welding increases: manual welding is impossible like an automated machine, and the welding is done in one go. Then, the more the number of pauses in the welding process, the more the aluminum alloy material is welded, the toughness becomes lower due to repeated heating problems. ”

“The welding speed is different: we all know that whether it is cooking or welding, there is an optimal completion time. For example, the welding of an aluminum alloy material, the most perfect welding quality, is the torch advances three millimeters per second. Machinery This can be done precisely, but by hand, it is never possible to meet this requirement."

"You can't do this, just like cooking. It's not a birth or a paste."

"So the mechanical engineering chair in front of the eyes, the look of light looks good. Aluminum alloy is a soft metal, the hardness and toughness are low. If the merchant does this, it is not afraid of the mechanical engineering chair, because the strength of the outer casing is broken, hurt. To the user?"

Soon after, I updated a Weibo with a video.

The video screen is a German KUKA MIG automatic welder that works in the welding of aluminum alloy containers.

The arm-like manipulator, the blue welding arc, and the white inert gas that transpires make many audiences scream.

Then the mechanical pioneers released a big move: "This German KUKA MIG automatic welding is more than 5 million, and the sales of mechanical engineering chairs for one day can be bought."

"Domestic is cheaper, hundreds of thousands of models are available for selection, and the business of mechanical engineering chairs, even this little money for them, can not bear to pay."

The comments below exploded immediately.

This time, many viewers have said something ugly, and there is no conscience in the market, and earning black money and the like.

[The sales volume is so hot, even the automatic welding equipment is reluctant to buy. 】

[From now on, I will buy the products of this merchant again. 】

[Served, the original manual welding defects are so large. 】

[Who is buying this chair, it’s really a problem. 】

The mechanical forerunner then updated Weibo, saying that there is no confidence in the mechanical engineering chair. It is necessary to unload it and let the audience appreciate it.

Seeing this, Ye Qing breathed a sigh of relief.

Since this guy can completely ignore the mechanical engineering chair, it is called the art shell welding technology, and the quality of the memory sponge.

Then when he unpacks the chair, he will naturally make a big fuss, and use many knowledge that laymen do not understand to reverse black and white.

This does not require any difficulty, and it is too easy for insiders to flick outsiders.

It turned out to be a clown with a jump beam, and in a blink of an eye, deliberately smeared the mechanical engineering chair.
