Back in the office, Li Ming immediately asked his subordinates to place an order for Ji Donglai, which was a set of elbows for automobile engines, and a cloth hose of 90 degrees.

"Viton rubber, this thing is not easy to get, and the mold is a big problem, unilateral molding and then core pulling, this tube will crack 100%, and double-sided molding requires a lot of processing accuracy for parts!"

Looking at one of the drawings passed by Li Ming, several people from the technical department sat together, and Ji Donglai sat next to him, staring at the structure in front of him quietly.

There is a core pull, there is a T-slot at the bottom, and neither of them is a good molding structure.

The outer T-slot can barely be made with a three-petal mold, and the inner one is not easy to do! Ji Donglai held the water glass, and several other people also began to sketch on the white paper.

"The core is made of two sections and four sections, and the cylinder is tightened and ejected, with two sections on each side! This is the structure used for core pulling!"

Ji Donglai flipped the structure of various molds in his mind, and finally picked up the white paper and sketched it on the paper, especially the right-angle part, using the structure of the head bang, three mold openings, and two core pulls!

The roughness of the mold core is higher, and the surface is coated with Teflon, a product with very good self-lubricating properties, which is actually a non-stick material.

The material is still P20, imported materials, Daqizi directly adjusts it, and then forges freely, and the mold processing time is about one month.

Rubber materials and knitted fabrics are provided by Li Ming, including release agents.

"Do you think the factory can design the right mold?"

Several technicians from the Li Ming rubber factory gathered around and glanced in the direction of Li Ming's office, this set of molds has been made three times in this factory, and the results have always been very poor.

Without exception, they are all stuck on the demoulding in the end, and the huge holding force of fluoroelastomer products makes the operator miserable. The product simply doesn't come down.

Not to mention the complaints on the production side, even the process department of experimental mold molding has dropped the rake, who likes to do it, grandpa will not serve.

The rubber hardness is too high, and the pipe wall is thin enough, so if you want to make it successfully, you must have enough practical experience in production, but unfortunately most of the newcomers in these big factories are the kind of whites who work behind closed doors.

As for the old workers who are now waiting to retire and give guidance to the young? There is no door, isn't it fragrant to apply it in your own factory after retirement?

As for the middle generation that Li Ming is responsible for, it's very embarrassing now, and you can't always do all kinds of things by yourself, right? Young people have to train you, first of all, these people like to learn, right?

The top students of domestic colleges and universities enter here with all kinds of arrogance, coupled with arrogance, the old technicians in the workshop certainly don't like to teach.

In addition, Li Ming has about half a year to go abroad for construction, so how can he have time to train new people.

Therefore, in the past two years, various accidents in the factory have occurred frequently, and many product designs have been a mess.

In the end, the vast majority of products have to be outsourced to some brother units, and the direct result is that the technical strength of brother units is getting stronger and stronger.

"What can that little ruined factory do? You see, those old and young, it's hard to do anything! That little kid also bragged that he was in charge of technology in a foreign company, and the foreigner's brain was caught by the door? If you don't have any project experience, you're in charge of technology?"

A middle-aged man led by him glanced at the direction of Li Ming's office, and his heart was full of dissatisfaction.

The original mold of this set of products was designed by the other party, but the mold molding effect was particularly poor, and the other party discussed and modified it many times with the outsourcing manufacturer, and the final result was that the outsourcing manufacturer did not modify it.

The reason is very simple, you have a set of molds modified more than a dozen times, and in the end you don't know which direction to modify, how can I modify it for you? Grinding and chirping to ask us for opinions? We have the opinion to return to you the outsourcing factory of dry wool.

Besides, we gave advice, isn't it our responsibility if something happens? So the outsourcing factory quit, and when Li Ming called to inquire, the other party told the truth that Li Ming criticized the designer severely.

Now this set of molds is re-outsourced to Ji Donglai's side for design, and Ji Donglai's technical department is rooted

Ben didn't have any communication with this technician, and it was completely designed by himself.

Occasionally, technicians were sent to take pictures next to the equipment in Li Ming's factory, and they looked at the on-site power connection and various supporting facilities, and then there was no more.

This hurt the technician very much, after all, he is the direct leader in charge of this project, and this thing really has nothing to do with him, and there is no email communication or anything, which means that he has no credit at all, and he has no experience in design.

Li Ming originally looked at himself as unpleasant, can his income come up in the future? The basic salary of such a large factory is very low, one thousand five thousand. With a variety of bonuses and benefits, it can be opened up to four thousand. qs

The premise is that you have a project in your hand, and the premise of a project is that the leader can see your ability, and it will eventually fall on the technical strength.

The other party is now very worried that Ji Donglai will make the mold here, and at the same time, he also hopes that Ji Donglai will make the mold here, so that he can learn it.

The ambivalent mood prompts the other party to be very sensitive when he hears about this project, just like an angry cat, who is close to biting whom.

"If we don't go to the site where Ji Dong came to see the processing, we can't get to accumulate some experience, technology is a process of continuous learning, there is no shame!"

An older engineer was good with the other party, half a master, patted each other's shoulders and whispered a word in the other party's ear, and then left quickly.

The other party thought for a long time, and finally accepted the old technician's suggestion, applied with Li Ming, and then went directly to Ji Donglai's factory to station.

But after only one day, the other party came back, not for anything else, the environment was too bad.

At least the site of Li Ming's factory is epoxy floor paint, an independent pantry, 20 hours of continuous hot water, and all kinds of benefits are all over the world.

In Ji Donglai's mold processing workshop, although there is also a rest room, it is separated by the kind of insulation board, and there is air conditioning inside, and the workshop is hot.

Workers blow fans, and the workshop is filled with the smell of cuttings and kerosene, coupled with the roar of equipment.

There are all kinds of large items hoisted back and forth, and there is a huge roar that cuts off the other side, and the other party really can't stand it.

As for the mold parts that Ji Donglai came to dry, they were only semi-finished products, and the other party couldn't understand them.

As for the design drawings, the on-site workers do not show them to each other at all, which is the secret of the factory. Besides, the procedures were all done by Ji Donglai, what can you see?
