But when it comes to full-scale production, large orders often fall into the hands of foreign-funded or joint-venture factories like Sver, and small factories jointly developed can only get small orders.

But these lists are absolutely no problem to feed a small factory, and there are countless small factories attached to the elevator factory in Tianjin in China.

Every year, a large number of factories are eliminated because the other party cannot afford it.

Without independent R&D capabilities, they can only be at the mercy of the technical engineers of the elevator factory, and they don't know the direction of their efforts. What's more, designers don't know the direction, especially when it comes to polymer materials, such as rubber springs and plastic properties.

Of course, stamping, metal materials...... Everything is important.

Don't look at these engineers who have obtained good positions in foreign companies with their high education abroad, it is difficult for them to have such a wide range of knowledge reserves!

There are very few people like Li Dequn who can accumulate so much knowledge before the age of 40 and obtain the title of chief engineer. But the other side also has shortcomings, English!

The other party is a technical controller, and he can't figure it out in English, otherwise he would have risen a long time ago.

Ji Donglai has been working in elevators for at least eight years in his last life, adjusting small products such as elevator sliding boots.

"This is simple, I'll give you a docking when it comes to any questions! The actual investor of that factory is my classmate's father, and foreigners inspect samples on the spot to do sabotage experiments......"

After completing the handover with Li Dequn, Ji Donglai's heart was infinitely happy.

I made changes to this document directly, and then printed it out and took it directly to the factory.

"Do you need to open so many molds at once?"

Looking at the mold drawings that Ji Donglai brought over, Lu Shipeng's eyes were also full of surprise.

Ji Donglai designed the mold for this set of skating shoes, and there are 12 sets of molds for cutting the main body alone, and 3 sets of molds for bending.

Shoe rail frame, cutting is two sets of molds, pressing is two sets of molds, shaping and bending are three sets of molds.

The skeleton of the rubber spring, cutting two sets of molds, and one set of molds for reinforcing ribs.

When the whole skeleton was welded, Ji Donglai opened three sets of molds, after all, this kind of mass thing, Ji Donglai couldn't let people pout their butts over there and rely on their feel to do it.

The product quality stability made in that way is much worse, and it is easy to hurt people, and the efficiency is too poor.

As for the plastic slide liner, Ji Donglai opened a set of molds, and Ji Donglai opened a mold of 16 cavities for the transfer mold of rubber springs.

The non-standard bolts inside, Ji Donglai is a little difficult to come over, this thing is particularly large, tapping is a problem, and the surface treatment needs to be galvanized.

Moreover, the surface of the main body of the skeleton of the sliding shoe requires spraying, and it happens that Ji Donglai has this set of processes in the particleboard factory, and the two can theoretically figure it out, as long as it is slightly modified and an electrostatic electricity can be added.

It seems to be a simple small product, Ji Donglai needs to get a lot of things if he wants to do it, and he really can't find a supporting match in the surroundings, so Ji Donglai can only pull the product down Hebei to do surface treatment.

"It's hard to buy a steel plate of this thickness, and it's a full-scale plate on it, and the price is at least a few hundred more per ton......"

Looking at the five-millimeter foot plate on the drawing, Ding Aixing was a little worried.

During this time, Ding Aixing learned a lot of things with Ji Donglai, especially all kinds of hardcore knowledge, which Ding Aixing couldn't get into contact with at school.

According to the experience imparted by Ji Donglai, cold-rolled plate and hot-rolled plate are two completely different standards, and cold-rolled plate basically meets the thickness requirements of the plate.

The vast majority of hot-rolled plates do not meet the requirements, especially the general cutting corners of domestic rolling mills, and they have worked the thickness if they want to make more money.

With a size of five microns, a coil of steel can be sold for hundreds of thousands to hundreds of thousands more, which is a small account that exists in reality, which seems to be inadvertent, but it is a big profit for the rolling mill.

"I have a way to make steel, you guys have a few experimental processes, once the mold is brought back, remember not to stop for a moment, this job is a big deal!"

Ji Ping's factory is dry-rolled steel, Ji Donglai talked to his father a few days ago, and now the efficiency of the factory is not good. Originally, when the benefits were good, there were four electricians in black and white shifts on the factory side, but now only Ji Ping is left as an electrician.

And it's not that the queue is full, Ji Ping has the opportunity to come out to make extra money, and Ji Donglai is quite familiar with the factory owner.

"I don't even bother to open the book for you this amount, Donglai, what position are you in that factory now? How much can they use? ”

Yu Wei, the owner of the rolling mill, sat in the reception room, playing chess with his subordinates, and chatted with Ji Donglai without a match.

Ji Ping's family background Yu Wei understands that he is not the kind of person who has a wide range of friends, so Ji Donglai is on the side of a foreign company, Yu Wei guesses that he is a clerk at most, and don't think about anything else.

"What I do is translation, I happened to come across this drawing, I saw that this time there is a lot of work, so now buy some steel plates from you, I heard my father say that there are a lot of steel plates in your rolling mill, we are all acquaintances, and the trust in each other is also a little higher, there are regulations in the factory, and the payment cycle may be longer, can you do it here?"

Looking at Yu Wei and expressing great importance, Ji Donglai directly indicated that he was a translator of Swell Company, and Yu Wei just raised his head.

"In China, the price list of our steel plate is available on the sales side, you just ask them! But credit is not good, and our rolling mill is not only a shareholder, so I can't be accommodating, please understand! ”

Looking at Ji Donglai and still a child, Yu Wei's face was not waiting to be seen, and secretly said You are a little child, be a translator?

There are so many college students in the capital, those foreign-funded factories don't have to be, do you want you? Joke! What a real electrician family has such a big fool!

Moreover, now that the efficiency of the factory is not good, and Ji Ping's salary is also pressing, Yu Wei seems that Ji Donglai is singing a play with Ji Ping, and is ready to get some steel as collateral.

In case the salary is not paid, the steel is taken directly, this inferior method was used by Yu Wei in his early years.

Now there is a lot of steel all over the country, and sales are also in trouble, even if it is close to the Beijing circle! Yu Wei has a large amount of steel in the warehouse, hoping to have a suitable buyer, but it is definitely not a half-grown child like Ji Donglai.

It was said that the economic situation would improve, Yu Wei was also waiting, so he saw the road repair, and he didn't see the rest, Yu Wei got angry when he thought about it.

"Uncle, my father is still working for you, can't you be accommodating?"

Looking at Yu Wei's appearance, Ji Donglai was a little disappointed.

After all, Ji Ping has worked in Yuwei's company for more than ten years, even if it is an acquaintance's face.
