He Xiaolong is the second batch of students brought by Ding Aixing. He usually keeps quiet and does whatever he is told.

He is also quite down-to-earth, he looks very thin, but his eyes are different from those of the people around him, including Ding Aixing.

Ding Aixing is the kind of person who has leadership skills and will never be silent at any time. In any situation, Ding Aixing can make arrangements for the other party.

But when he was actually working, He Xiaolong was the kind of person who really worked without talking. Before Ji Donglai, he was only familiar with him by face, but he didn't expect that he was always thinking.

"Okay, boss, I will do a good job!"

After receiving Ji Donglai's advice, He Xiaolong suddenly felt enlightened. When the mold was opened, the other party hurriedly took a crowbar and started to separate the mold.

"Hey, Ji Donglai, can you still do this?"

Ji Donglai was observing the molding of the product. When he turned around, Tan Xiumei was already standing in front of the iron basket, holding a rubber spring in her hand, with surprise in her eyes.

"It's hot, be careful!"

Ji Donglai quickly got a towel for Tan Xiumei. Ji Donglai did not explain. Tan Xiumei held the rubber spring and looked at it for a long time. Seeing the vise next to it, she took the tool and started to pull the two bolts of the rubber spring with all her strength.

"Sister, you can pull it off, or even a crack appears, and I eat it! Although this place is a little smaller, it is definitely not a small workshop. In terms of craftsmanship, I am definitely good at it!"

Looking at Tan Xiumei's blushing face and rough neck, Ji Donglai hugged her shoulders and looked at her with a smile in her eyes.

"Follow me, something good will happen!"

Seeing that the threads under her tool had all been crushed, and there was no peeling between the rubber and the frame, a smile appeared on Tan Xiumei's face.

Ji Donglai didn't know what kind of medicine the other party was selling in his gourd, so he got into the other party's car. After about an hour, the car entered a mountainous area.

"Let me tell you, where is this place? This road is so good!"

Ji Donglai was surprised when he looked at the all-concrete road under his feet. From time to time, large trucks pulling coal passed by on the road, and the wheels rolled up the smoke and dust.

Tan Xiumei didn't say anything, and as the road extended, the car entered the depths of the mountain.

A majestic factory building appeared in front of him in the distance, with towering chimneys and dense pipes. Combined with the turbid air around him, Ji Donglai covered his nose.

The car moved forward slowly, and the road under the wheels began to turn black until it reached the door of the workshop, and Tan Xiumei got out of the car.

"Mr. Tan, why are you here in person?"

A person in charge, wearing red clothes and a white hat, walked towards Tan Xiumei with a smile on his face, and briefly introduced each other to Ji Donglai.

"Gong Li, this is the quarterly worker from our processing plant. He is here to see your rubber parts. He specializes in making this! You show him the scene. Don't there always be problems with our products? Let Ji

Dong Lai helps us solve it, he is very powerful!"

Smoke and dust billowed all around, and from time to time water pipes in the air sprayed out a burst of water mist. The air became humid, mixed with the smell of pulverized coal. The smell was as unpleasant as possible. Tan Xiumei took out a mask and put it on herself, while Ji Donglai

Follow the person in charge into the scene.

"Ji Gong, this equipment is called a tamping machine. The principle is that a cam clamps the tamping hammer upwards, and then relies on the weight of the tamping hammer to fall down, pounding all the coal powder below!"

"The rubber products we use are installed on the cam roller to provide clamping force..."

While Engineer Li was talking, he took Ji Donglai into the on-site maintenance workshop. Several workers were repairing the cam of the tamping machine, which had a pile of things similar to rubber spring pads for elevators.

Different from Ji Donglai's rubber spring, this one is internally threaded and connected to the side plate with strong bolts.

There are twenty-four internally threaded rubber springs on one side, and a pair is a group of forty-eight. The side plates are installed on the crankshaft. Driven by the motor, the cam reciprocates to provide power for the tamping hammer.

The problem the other party faces now is that the service life of the rubber spring is very short. A longer one can only be used for one year, and then the skeleton of the rubber spring will deform.

The joint between the rubber and the frame will fall off, eventually causing the cam to lose power and the tamping hammer to be unable to carry out normal production activities.

Now this processing factory has been using imported rubber springs, which are too expensive and require only one batch each time they are replaced.

Forty-eight rubber springs cost 20 US dollars each! It costs almost 7,000 yuan to replace a rubber spring for each mobile unit, and the entire machine costs more than 100,000 yuan!

Ji Donglai counted more than a dozen tamping machines in this workshop.

The profit point of this company used to be very high. It cost hundreds of thousands to replace the rubber spring every year and no one felt anything. But now it is no longer possible. The economic crisis has made life difficult for everyone, and costs must be reduced everywhere.

Shareholders have been discussing localizing this thing and reducing costs! A friend of Tan Xiumei is a major shareholder of this company. Originally, the other party and Tan Xiumei said that they were just casting a wide net.

Unexpectedly, Ji Donglai was also making similar things. Tan Xiumei asked Ji Donglai just to give it a try.

"Ji Gong, do you often make this?"

In the temporary lounge of the workshop, the person in charge on site looked at Ji Donglai holding the rubber spring and observed carefully, secretly thinking that the person the boss had found was reliable.

"There are many similar products. There is something wrong with the design of your product. Can we change the structure inside?"

After carefully observing the joint surface of the products, Ji Donglai understood everything clearly, and then he raised his head, and Tan Xiumei came over.

"No, the product structure must not be changed! You can only make foreigners' products what they are, so that we can still explain it. If you change it, if there is a problem with the product, it will be a big problem for the superiors to investigate!"

"The foreigners designed it like this, and you must design it so that there is nothing wrong with it. At least the leadership will not raise objections regarding the structure! Once there is a problem with the product, it is easy for everyone to find the reason, whether it is your fault or the molding process.

So you must strictly follow the original design of this product, regardless of whether it is reasonable or not!"

"To tell you the truth, Ji Donglai, many people have looked at this product, but no one has chosen to take it! Most of the reasons are because of the special nature of this product!"

"If you want to make this product good, you have to think about it. If you can do it, just do it. If you really can't do it, forget it!"

The person in charge of the scene took out a cigarette, and Ji Donglai lit it directly for him.

"It's okay not to change the structure, but the service life of the product will definitely be reduced. I work in this industry and know the ropes better than anyone else! Apart from anything else, our domestic rubber materials have this virtue and are as good as those of foreigners.
