"Donglai, don't worry, don't expect to find a one to remove rust for you in this market, even if it is rust removal, it will cost money, you know? If you don't believe it, you can go to the market and ask, Uncle will definitely not fool you......"

From Ji Donglai's question, An Peng judged that Ji Donglai was a layman, so it would be easy to do.

Ji Donglai secretly slandered himself, and then simply said hello to the other party, and then returned to the county.

"Donglai, when will you come to pull the steel to inform me, uncle can't shorten your benefits......"

Putting Ji Donglai in the position of the rental bookstore, looking at the miniature car parked next to him, An Peng felt more determined. There are very few foreign companies that can provide cars to Chinese employees, and Ji Donglai definitely has the ability to introduce himself to it.

Once Ji Dong comes over there to help him pull the strings, the rest will be easy to do.

"I'll let you know as soon as there is news, uncle, you are busy first!"

Out of politeness, Ji Donglai did not directly refuse An Peng, it happened that Jerry's phone came over there, Ji Donglai waved his hand and began to communicate with Jerry in English, and An Peng did not drive away in a hurry.

Listen carefully, even if Ji Donglai has already gotten in the car.

An Peng only remembered that Ji Donglai said OK in the car, naively thinking that his affairs were eyebrow-raising, and he had to invite Ji Donglai to dinner.

"Uncle, I still have something to do here, the foreigner is waiting, I'm back to the factory, I'll look for you when I have something to do!"

Jerry is looking for Ji Donglai to come to the boots, which is basically the same as Ji Donglai's expectations, this time the product development of the boots, Swell only did the rubber spring part and the plastic slide liner.

The rest of the skeleton, together with the inner cavity skeleton of the slide rail, are all processed externally.

Looking for Ji Donglai is to let Ji Donglai come back here to connect with suppliers, Wang Rui left some suppliers for the company in the past, and the rest are newly developed at this stage.

As for the metal skeleton and non-standard bolts required for rubber springs, all of them are outsourced without exception.

This time Ji Donglai has more confidence in his heart, all suppliers are in his own hands, it is not difficult to join a company of his own, and Ji Donglai himself is also responsible for reviewing the information, which is more convenient.

"Tsk, this is too strict, who can complete it, it's not easy to make a product with such strict size requirements in a short period of time!"

A bunch of vendors sat in the conference room, looking at the drawings sent by Jerry, their eyes full of worry.

Sheet metal parts have always been the most difficult to guarantee the size of all products, and this set of products also includes welding processing, the size given by the elevator factory is plus or minus zero point of one tolerance, which is almost impossible to achieve in sheet metal parts.

Moreover, it has to go through surface treatment, which alone will make the tolerances fly, not to mention that spraying, transfer, and collision in the middle will also lead to dimensional deformation.

If you really process according to this tolerance, a lot of supply on the site cannot be guaranteed at all, and the final result can only be a variety of SDR applications, and then treat and give gifts.

"Mr. Jerry, they say that the tolerance range of this drawing is difficult to achieve, and if it is really such a strict tolerance, it is basically impossible to do it!"

Ji Donglai whispered to Jerry to translate the reaction of everyone at the scene, and Jerry was also observing.

"Ask them, what is the range of tolerances they can achieve? What a price! ”

Jerry is not a layman, the processing of this kind of product is actually not so strict, it is the management of the Asian headquarters to modify the original factory design drawings, on the one hand, to absolutely ensure that the quality of the product is qualified, on the other hand, it is also to use these impossible to create profits......

Normal dimensions require accuracy of plus or minus one, and within this range, Jerry has the right to let go.

The reason why the tolerances are so strict now is that the Asian headquarters has narrowed the tolerance band in order to reduce trouble in the future, so that the products produced will be 100% qualified, which is the legendary layer by layer.

"According to this size, it has to be put at least plus or minus 1.5, and the size of the sheet metal parts will change as soon as it moves, which is not easy to do......"

One of the suppliers took the lead in putting forward opinions, and then everyone began to echo them, Jerry's brows gradually wrinkled, Ji Donglai also studied with Jerry on the surface, but he was very happy in his heart.

Now the more these people complain, the better it is for themselves.

The whole process is guaranteed with tooling to ensure the size, and the sheet metal parts are not difficult to dry in the later stage, but many people have not made similar products, and they have no bottom in their hearts.

"Absolutely not, I can admit at most plus or minus 0.4, if you think you can try it, you might as well take it back and try it, we need to receive your reply within a week, it is best to be able to send samples, if you miss this point in time, we will give up! For the manufacturers who firmly stand with our factory this time, we will increase cooperation in the future product development process! ”

"We have a lot of follow-up products, I hope you can stand with us, thank you!"

Ji Dong came over there to translate, and everyone's expressions were a little better.

But the time to come up with the sample within a week was still very tight, and in the end, Jerry relaxed the time for the gang to half a month.

At the conference table, Liu Yupeng's eyes were full of smiles at this time, the press rented by Ji Donglai yesterday has landed, and the stamping die can be tested in these two days, which means that Ji Donglai is one step ahead of these people.

The amount of this product, once it is taken down, the two of them will make a fortune.

Returning to the small factory, Liu Yupeng and Ji Donglai were busy together and began to inspect the mold, and now there are more and more people in the factory, and Liu Yupeng has become the sales minister.

"Click!"

"Damn, why is there such a big movement?"

Next to the punch, Liu Yupeng stared at the cutting mold with blazing eyes, and as the punch fell, a loud sound of metal tearing frightened Liu Yupeng to cover his ears, and the rest of the people were not much better, only Ji Donglai was calm at this time.

"Don't be afraid, this is normal, don't you have to call if you have a broken arm? Remember to wear earplugs when you work, long-term work at such a high decibel level will hurt your eardrum a lot! ”

Ji Donglai has long been accustomed to this environment, and Ji Donglai was calm throughout the whole process of the experimental mold.

The students were no longer afraid when they saw that Ji Donglai, the boss, was so calm.

Ji Donglai only bought two pieces of steel plate for the test machine, stamped out the first sample, Ji Donglai adjusted the pressure of the punch, checked the flash, and Ji Donglai adjusted the die gap.

In this way, when the third sample was made, the size and appearance basically met Ji Donglai's design requirements.

Then there is the bending die, compared to cutting, the power of the bending die is much smaller, the largest is ten tons, five or six millimeters of steel plate can be easily folded into ninety degrees.
