I still have some money left in my hand, and my cousin can squeeze some out of it. I have to give some advance payment for the product, right...

Ji Donglai is very tight-lipped about raw material manufacturers, who dares to say no?

Even if Ji Donglai asks for raw materials without paying for them, all these raw material dealers have to give them! Ji Donglai has already accumulated all the formulas. As for the equipment? His mother Ning Caiyun’s original processing plant now has a lot of idle equipment waiting to be processed.

.

Now that the house matter has come to an end, all that is left is to focus on the college entrance examination and career, Ji Donglai thought carefully in his mind.

"I don't care about that, Dong Lai. I know you have a lot of things in your mind. I want a mobile phone case! It's up to you. If the price I give is high enough, I'll make it your own. If the quantity is large, I'll do wholesale. If the quantity is small, I'll do it wholesale."

Just sell retail! It will be of great benefit to you. I am waiting for the letter. Anyway, I can tell my grandpa and the others about someone..."

"Okay, you are so good-looking, but how come you have such a vicious heart? The wine, red wine, face, wealth, and silk are alluring to your heart, and you have them all. How did you raise me up?"

Wang Jue looked at Ji Donglai and fell into silence, judging that Ji Donglai must have a solution.

After experiencing several things, Wang Jue now fully recognizes Ji Donglai's strength. Now he seems to regard Ji Donglai as a Doraemon! If you can make a wish, make it. Whether it can come true depends on Ji Donglai himself.

"Donglai, I helped you with the demolition team last time. You have to help me this time, otherwise..."

Seeing Ji Donglai still hesitant, Wang Jue added fuel to the fire, and Ji Donglai rolled his eyes.

Finally, he agreed to give it a try. In fact, Ji Donglai had already made a good plan. That night, he took the mold that Cao Ren had broken to the Panasonic factory.

Lu Shipeng is on a business trip these days, and Ji Donglai happens to be watching all the factories.

Because the Swell side needed to meet the construction deadline, Ji Donglai sent the master who was looking after the students directly to the old factory, while he changed into work clothes and started to check the condition of the mold in person.

From the outside, there is nothing wrong with the mold, but when it comes to Panasonic's large-scale 2D model, the deformation of the mold is immediately visible.

"It has changed so much. I sandblasted the entire surface, then plated it, and then installed a grinder here. Hey, it should be possible to directly change these cores to plug-in types!"

Ji Donglai clicked his tongue as he looked at the damage to the mold under the camera, and various repair plans passed through his mind.

According to the traditional process, the wear-resistant layer on the mold is directly removed, and then the entire mold is plated with a layer, partially corrected in a timely manner, and then plated with another layer.

This can not only ensure that the mold deformation is partially self-recovery, but also ensure that the correction amount is minimal.

Ji Donglai simulated the mold structure on a computer, and finally decided to change the mold structure so that the core would be replaced directly if the core wear becomes too large.

"Here, open a set of molds for me, and then forge one hundred and twenty for me. I'll use them later!"

After repeatedly considering various situations, Ji Donglai finally took the design drawings of the core to Lu Shipeng's processing plant and asked them to open a set of forging dies.

High-frequency heating, one-time stamping and forming, followed by surface finishing.

The master craftsman on site took a look at Ji Donglai's design drawings and kept nodding. No matter from the perspective of processing or cost, Ji Donglai's craftsmanship is the best.

"This mold is machined with holes according to my design drawings. Remember not to polish the bottom position, and ream all the rest!"

Worried that the students would not understand, Ji Donglai took the mold back to the processing factory again.

All the integrated cores were removed with a milling machine, and the surface of the base plate was punched according to the design drawing. Because there were few people, Ji Donglai asked the workers to put the molds on the bed, and processed the tools himself. Even the procedures were typed on site.

"Mr. Ji, how many years have you been doing this? We don't have many masters who can do the machining alone on site. Most of them have been working for five or six years before they are confident enough to work in the machining center. It would not be a good thing if this thing hits you.

!”

Looking at the machining center, Ji Donglai was simulating the machining route, and the small workers were assembling tooling and fixtures. Several senior craftsmen came around with admiration in their eyes.

"My grandfather is a worker at the Jingshan Iron and Steel Plant. I have been working in the factory since I was a child. I know the basic things. Of course, if it is too difficult, I have to ask you. Okay, you can just watch the rest. Let them finish the processing.

Clean it up for me, call me and I'll come and take it away!"

After the explanation, Ji Donglai rushed back to Hebei without stopping overnight, and asked Wang Jue to help connect the cables to the small courtyard.

Buying an injection molding machine was a smooth process.

Although the domestic SJ-type injection molding machine is not the most advanced on the market, it is still acceptable for use. Ning Caiyun used to come from this factory, and many people know Ji Donglai.

When he wanted to buy equipment, Ji Donglai picked it out and looked at the parts on the equipment so he could just dismantle and replace them.

Originally, Ji Donglai wanted to buy equipment, but the leaders in the factory were hesitant, and Ji Donglai was also thinking repeatedly. After all, the equipment was too old! In the end, Ji Donglai decided to rent it, and the annual equipment usage fee was 3,000 yuan.

The factory director heard that if the equipment is leased, the ownership of the equipment still remains with the factory, so it is not considered a violation. Even when the equipment is finally liquidated, the other party will say so.

So according to the agreed price, two pieces of equipment, each costing 3,000 yuan, Ji Donglai paid 6,000 yuan. In addition, there were some workers in the factory who were doing maintenance and needed to be paid, so Ji Donglai was very busy with this matter.

smoothly.

On the transportation side, Liu Yupeng called Ji Donglai and asked for a car. The people loading the car were all driver friends of Liu Yupeng's parents.

Just like that, the next morning, Ji Donglai appeared in the warehouse of the small courtyard with a few intern students and electric picks.

It is said that the warehouse is actually a simple partition with the boiler room, and the height is the same as that of the boiler room. It is at least eight meters away, and the ground is all made of cement. Ji Donglai and a few students can go down

After digging to a depth of 400 meters, we finally found the muddy ground.

"Lower the anchor bolts, throw down one of the ground wires, and dig a water pipe here. Cooling water is needed here. Separate the cable trench and the water trench. I will get the electricity later. Driver, please drive the car in.

Bar!"

Landing the equipment is a big job. It looks simple, but the anchor bolts must be firm, otherwise the equipment will be seriously deformed after running for a long time.

A raw material crusher, an injection molding machine, another granulator that Ji Donglai relied on to pull back, and a kneader. Ji Donglai and that factory only rented a crusher and an injection molding machine.

As of now, Ji Donglai really doesn't have many tickets left, and he has to leave some money for raw materials, so he can only adopt this strategy.
Chapter completed!
