Black technology: I have a refitting factory

Chapter 63 The First Batch of Parts of the New Casting Line

Melt the material and start casting in batches according to the new method.

The assembly line started running normally and orderly.

Small castings began to take shape one by one.

This time the test machine is cast with small parts selected, which can save a lot of time, otherwise it may take 30-40 days for large castings under normal circumstances.

Even with the method provided by Su Qi, it will take 15 to 25 days.

It is impossible for everyone to wait all the time.

As for the selected small castings, it takes four hours to finish all of them.

Four hours is actually a very long time, but for those who are waiting here, everyone does not think it is too long.

It is a kind of enjoyment for those who care about this piece to see the automated production line, the process is carried out one by one, and the casting is gradually formed.

Four hours flew by.

At this time, the casting has reached the last link, cooling and forming.

The originally relaxed atmosphere suddenly became tense. After it is formed, it means the beginning of the inspection. Now we can really see whether it can meet the standards and what level it reaches.

pat!

The first casting fell into the frame, and the personnel who had been waiting here immediately stepped forward, picked up the casting and ran to the inspection room.

The rest of the people also walked towards the testing room under the leadership of Tian Tengfei.

The overall performance of castings is mainly from two aspects, one is the surface quality and the other is the internal quality.

The surface quality mainly refers to the surface roughness, the precision of the outer dimension of the casting, the angle tolerance, and the appearance defects such as pores and cracks.

Internal quality generally refers to air tightness, hydraulic sealing, heat treatment, and internal porosity.

Generally speaking, the surface quality index that the international mainstream precision casting of this small casting needs to achieve is...

The surface roughness is 0.63-1.25μm.

The accuracy of the external dimensions is within ±0.10mm.

The angle tolerance is about ±0.5~±2.0 degrees.

The company that dug the hole for them requires a surface roughness of 0.60 μm, an external dimension of less than ±0.08mm, and an angle tolerance of 0.75 degrees.

Speaking of this, Tengfei Casting can barely achieve it.

The key is that the other party has made requirements on the quality of the material, and needs a titanium alloy that is more difficult to handle.In addition, there are requirements for pressure resistance and fatigue resistance.

It is simply impossible for this kind of casting to achieve the indicators mentioned above.

The other party used the salesperson's only half-knowledge and aggressive tactics to make Tengfei Casting sign the contract.

"Chairman, the surface roughness test results have come out, only 0.3μm!"

The tester in charge of testing the surface roughness shouted in surprise.

"The external dimensions have also been tested, 0.03mm!"

"The angle tolerance is also out, +0.2!"

……

As each tester reported the test indicators, everyone present was a little dazed. Everyone has been in this industry for many years, so why don't they know the concept of this indicator?

After working for so long, I have tried many crafts, but none of them can reach this target! !
Just outrageous!
"Brother Su, I can only say one thing, I am ashamed of myself!"

Chu Jianguo looked at Su Qi and opened his mouth to finally choke out a word.

He could see the power of the new technology, but he only felt that it would be good to improve the index by 20%.You must know that for precision castings, it takes a lot of effort to increase it by 2%.

As a result, this indicator has now increased by at least 50%.

Much better than expected.

"Fortunately, I met you in this take-off crisis!"

Chu Jianguo suddenly sighed again. Without Su Qi's participation, this takeoff would have suffered greatly.

"Yes, thanks to Xiao Su!"

Tian Tengfei also added a sentence.

"That's the opportunity given by Mr. Chu!"

Su Qi smiled and said, to be honest, if Chu Jianguo didn't like to understand how newcomers work, this thing might not have been implemented in Tengfei Casting.

"Su Gong is awesome!"

Suddenly someone in the crowd yelled, and then everyone yelled after him.

Su Qi felt a little unnatural when he heard a group of people call him awesome for the first time.

It's just... this unnatural feeling seems a bit wonderful!
Surface testing is over, the rest is internal testing.

The results of the internal test did not come out so quickly, but Tian Tengfei, Chu Jianguo and his team were not too worried.They had already verified the software Su Qi gave him before.

A very awesome simulation software.

Ninety-nine percent of the castings simulated on that can meet the internal testing requirements.

Waited until evening.

The results of internal testing are in!

Fully qualified and met all expectations.

This time, titanium alloy was used, and the designed casting performance also followed the requirements of foreign orders.In other words, this small casting completely meets the requirements, and even far exceeds it!

……

Germany.

Frankfurt, in a high-rise building in the CBD.

HAZETE Corporation.

This company seems to be located in the bustling CBD, with various high-end interior decorations.But in fact, it is a leather bag company.The business being run is a scam.

It's not entirely a scam either.

Just taking advantage of the urgency of some enterprises in underdeveloped countries to break through the markets of developed countries, they set up a situation to earn liquidated damages.

Every time it was reasonable and compliant, so much so that the owner could only break it into pieces and swallow it.

"Cobbs, I heard some bad news today!"

A fat foreign man hurried into an office.

Sitting in the office was another foreign man, gentle and gentle, wearing a pair of gold-rimmed glasses.Looking up and seeing the person coming, he raised his eyebrows and asked, "What news?"

The chubby man replied: "Dgro has an idiot who failed to sell equipment in Huaguo. Listening to the chats of people in their company, it seems that Huaguo has a substitute."

"What does this have to do with us?"

The man with glasses was surprised.

"I'm thinking about our setting up this time. If dgro does the same, we will lose a lot of money this time. The batch of goods we want is purely a fabricated indicator, and no one will use it."

The slightly fat man said, "Do you want to find some backup method?"

"Burke, this is because you think too much."

The man with glasses opened the drawer and took out a stack of documents, "I won't be like the idiots over there at dgro, these are survey documents about Huaguo Tengfei Foundry and Huaguo's overall foundry industry.

Do you think I just choose companies at random?
This was selected after preliminary research.

No Huaguo company can achieve the target we designed. "

"Taking a step back, there is no company in the whole world that can achieve that target. Huaguo, it is even more impossible in a short period of time! This time, Huaguo's take-off is a lamb waiting to be slaughtered.

Just sit back and wait for the bonus! "

"correct!"

The man with glasses seemed to think of something and said again, "Aren't you well-informed? You need to publicize this matter more. We are not bad people, but victims of Huaguo's substandard craftsmanship."
