And Wang Lu really gave some guidance, most of which were photos. In the past few years, Wang Lu has been training abroad for a long time, General Motors, Detroit, South America.

They are all experience in railway equipment transportation, which is very important for Ji Donglai, at least five years of detours.

Among them, the design of two sets of forward buffer plates attracted Ji Donglai's attention, which was simple and effective.

According to the model structure given by Wang Lu and the structural scheme of other related products, Ji Donglai took the CAD to simulate the position, and finally designed the structure of the product to be 800 long, and the width to be 600, 400, and 240 widths.

The thickness of the whole is eighty, and the hardness of the rubber does not need to be too high, eighty degrees.

As for the material, Ji Donglai uses the simplest material of industrial rubber sheet, which is also the cheapest, considering the huge weight of the vehicle itself, the huge rubbing force of 60 tons of weight on the surface of the buffer material, and the buffer material consumes energy in the form of gradual wear.

In fact, most of the energy of the buffer material is concentrated on the column of the carriage, as long as these points can be protected, but according to the requirements of railway inspection, the overall layout must be arranged more than a certain proportion.

The surface is coupled with a force relief groove, and the back plate is coupled with a steel skeleton, and the whole is welded on the surface of the vehicle support plate by welding connection.

As for the press girder, according to the car body structure, the steel plate is glued and trapezoidal.

As for the forming mold, it is the simplest, there is no need to process it on the machine tool at all, and the flame directly cuts the iron plate of 80 out of the groove, and the surface is polished, and the bolt connection is used.

In terms of molding, the lid is a ten-millimeter-thick iron plate, and the grooves inside are bolted to the surface of the bottom plate, and each time the mold is opened, it is directly jacked up by hand.

Ji Donglai alone opened three sets of molds, and three 300-ton vulcanizers were formed as a whole.

After the design was completed, Ji Donglai directly gave the task to the rubber mixing workshop, and the mold workshop also stepped up to do the design.

As for Wang Lu's side, the other party symbolically gave some "guidance" opinions, Ji Donglai immediately took it back to make modifications, and then made a plan for various things of the buffer material, and Mr. Wang gave "guidance" again.

In the evening, Ji Donglai had already formed all the plans into words and drawings, and then came to the place agreed with Tan Xiumei.

"Mr. Ji, I'm sorry last time, the different business methods of our two places have led to misunderstandings, please don't mind! If there is something wrong with what you did last time, please Haihan, I will do this cup first......

Compared with the last time when he was arrogant, this time Yu Yang was in a state of begging for people almost all the time.

Did Ji Donglai hold it, after all, he was doing business, and he didn't let the other party punish him for drinking, but accompanied him with a drink, and the other party wanted to drink Ji Donglai stopped him directly.

"Mr. Yu, let's talk about business, Mr. Tan told me about you in detail. I've been running about you since yesterday to today, and it's not about you as a brother, you're not doing something right!"

"You dare to offend even the people of the railway, I found a relationship between the top and bottom of the power plant yesterday, and I found a relationship outside, and then I talked to the other party. But this time you have to pay a lot of price, the rectification project must be done, but some things on your car need to be replaced!"

"I made a deal with them, and I had something to make here! Then install it on this car, and your original institutions will be dismantled, not that people will be difficult for you! You've been so careful about this project, and they're teaching you a lesson this time!"

"But people have also reminded that the acceptance criteria in the future are all this, if you want not to encounter trouble in the future, then do it in accordance with this standard in advance, so that everyone can avoid follow-up trouble!"

Ji Dong came up with his own plan and pushed it directly to Yu Yang and Tan Xiumei.

The two hurriedly took it in their hands to check, whether it was a text plan or a drawing equipment plan, Ji Donglai did it in great detail, Yu Yang was really convinced this time, in terms of professionalism, Ji Donglai did not lose to anyone at all.

But seeing Ji Donglai's offer plan, Yu Yang's pupils dilated slightly.

"This 700,000 set...... Boss Ji, this is a bit much, right? You see brother can't make a few bucks per set, you

Don't you say?"

Each set of cushioning materials is 700,000 yuan, this price makes Yu Yang's side a little painful, Tan Xiumei looked at Ji Donglai's design drawings, and smacked her tongue at this time.

"Mr. Yu, you have to pay the design fee! I can't get this money, someone has a patent, and this time it costs a lot! There will be various things in the middle of the trial production, I don't say that Mr. Tan must understand that if the trial production is not successful, I will carry the danger on my back!"

"When I give you a price reduction for Cao Feidian's set, the cost of trial production will be reduced, and let's say actually, Mr. Yu, this price is the market price, and it will be this price for other dumper manufacturers in the future, not only you!"

"Take 10,000 steps back and say, your brother has definitely made a lot of money this time, don't miss this money, with this acceptance, you can succeed in the next set!" If you don't inspect the car here, you still want to sell your equipment?"

"Do you know how much coal goes in and out of Caofeidian Port in a day? Don't let the small be the big!"

Ji Donglai was also a little apprehensive about this offer, after all, it was a bit high. But this is a new trick, Ji Donglai must grasp it, according to past experience, his own products have been made, and there will soon be manufacturers to imitate them.

Now the imitation ability of domestic manufacturers is too strong, and before finding someone to imitate, Ji Donglai must hold it, otherwise there will be no room for price reduction in the future.

"Okay, how are you going to charge for the cost of the Ji Zong's transformation?"

Although Yu Yang was unwilling, he still said that money is not earned by one person.

In other words, Yu Yang has no bottom in his heart, according to the design standards, this set of dumpers can almost be regarded as shoddy, and he got the project money as soon as possible, even if he doesn't want the final payment, the funds are in his pocket.

Once stuck here, there are more and more things that are turned out, and there is nothing more reassuring in this day and age than carrying money in your pocket.

"The renovation cost is 200,000, this is the cost price, I don't want you much, I earned your money last time, this time it's a gift! In addition, you have to come to the scene, not just do it ourselves, all kinds of procedures have to be followed by your people, to see if our money is good or not, we have to complete the construction, we must settle the payment at one time!"

"This time, we will ask you to pass the car inspection, this is the premise, but I won't ask you for money if you can't get the car inspection procedures, and please don't delay our money at that time!"

After the things are negotiated, Ji Donglai doesn't talk nonsense, after all, he relies on physical goods to make money, not to slander people.
