For seven days, Chen Changan spent the whole week, teaching 20 employees how to shape, solidify and increase tension by extracting and processing collagen from fish skin.

In order to keep it as confidential as possible, these 20 people were trained separately in groups of five. Although they could know what each other learned, they did not know whether the group they were in during the entire production process was an intermediate or final step.

Anyway, when the production officially started, it was produced on assembly lines. Each group was responsible for its own work, and then the factory workers transported it to the next group, and there was no contact with each other during the production process.

This is the most confidential production method that Chen Changan can think of.

This is how you run a business. You always have to take some risks. Naturally, the leak of formula is one of the many risks. This is inevitable. Unless Chen Chang'an never makes this suture, he will face this problem sooner or later.

There is no airtight wall in the world. His confidentiality methods are already at the limit. If they are more complicated, they will affect production efficiency and will not be worth the loss.

After the production training is over.

On August 25, Chen Changan brought Lu Jinsheng and others to Director Yang again.

"Director Yang, I am about to start trial production of the first batch of fish skin collagen sutures from our Ruikang Medical. Do you want to visit and visit?"

Director Yang looked at Chen Changan with a confident look and said with a joke: "The factory has been slow these days, I want to stare at it. Mr. Chen, please do your own thing. I wish you a smooth production and make the second collagen suture in China!"

He really has no time. In the past two days, a large order for 600,000 pairs of medical masks is to be delivered. He has to focus on many matters about shipping on the mask production line. He really has no time, otherwise he will definitely have to see the farce with his own eyes.

"Okay." Chen Changan shrugged indifferently, looked at Director Yang with a smile and said, "Don't forget the promise you made that day."

As soon as he mentioned this, Director Yang laughed loudly: "Hahaha, remember, of course, remember, Mr. Chen, don't forget. If you fail, don't interfere in factory matters in the future. Professional matters should be left to professional personnel. What do you think?"

"Of course!" Chen Changan nodded with satisfaction, took the employees into workshop No. 8, and started the first trial production with great enthusiasm!

First, the crude collagen stock solution is extracted from the fish skin, and then the crude stock solution is purified after several purification work such as removing heavy metals and removing fishy smell.

Afterwards, the purified fish skin collagen stock solution was carried out by Lu Jinsheng and twenty technicians who had received professional training in Chen Chang'an, and were responsible for the steps of shaping, solidifying, increasing tension and other steps.

The final formed collagen solidified substance is handed over to the factory's suture line staff to cut, cut, cut, needle and other processes according to different suture specifications. The final product is then chemically sterilized and then vacuum-packed with a sealed bag.

Although Director Yang disagreed with Chen Changan taking up the working hours of factory employees, Yang Changan took advantage of the loophole.

He has been in the factory every day these days, so he naturally has contacted some ordinary employees in the factory. Under his temptation, several employees agreed to him that after get off work, they could help him use the factory's production line to make collagen solidified into finished sutures.

Everything has been arranged by Chen Changan. Now only one finished product needs to be produced, so Director Yang can only surrender obediently, and there is no reason to resist Chen Changan's production of fish skin collagen sutures!

............

Three days later, the first batch of collagen sutures on fish skin were successfully made.

Because it was the first batch, several workers did a comprehensive job and made a batch of all the specifications and models that could be made. The thickest line 4 to the thinnest line 6-0 line, and the length ranges from the most basic 45cm line to the longest 125cm line, which is very complete!

After Chen Changan got the finished product, he did not announce the news immediately, but instead approached Director Yang.

It was still the familiar workshop No. 8, but today Chen Changan was the only one in the workshop.

"Dongdongdongdongdong."

"Enter."

Director Yang pushed open the door and walked in.

"Mr. Chen, are you asking me for something?"

Chen Changan looked at Director Yang, who looked puzzled and had no idea what was going on. He didn't say anything, but stared at him with a smile.

"I have other things to deal with. If you have nothing to do, I will leave first?" Director Yang was stared at him for some reason, and he felt a little panicked.

"Hey, wait!"

Chen Changan called out to Director Yang, who turned around and wanted to leave, and kindly held his shoulder, took him two steps deep into the workshop, and walked to a table.

"Look, what is this on the table?" Chen Changan nodded and signaled to Director Yang.

Director Yang glanced at the table in confusion, but just this time he was stunned.

"This...is this?" Director Yang stretched out his hand and pointed at the pile of sutures on the table, feeling a little confused and unbelievable.

"Yes, this is what I'm talking about collagen suture. It is collagen extracted from fish skin. It uses some special processes to produce resistance to absorption and tension. It is a unique technology in the world!"

"No, this is impossible! It's beyond common sense!"

Director Yang was very unbelievable at this time. He rushed directly to the table, picked up a suture thread and looked carefully.

From the appearance, this suture is almost the same as a normal absorbable suture.

But when he picked up the suture, he could immediately feel that the material of the thread body was definitely not the type of artificially combined and absorbable suture that he usually saw!

Because the thread on his hand was soft at this time! The touch was completely different from other sutures!

However, it clearly felt soft to the touch, but when he reached out and pulled it hard, the suture did not break, but instead became tense!

Even because Director Yang pulled too hard, the skin on his hands was rubbed violently with the sutures and the skin was even broken! A few drops of blood were flowing out of his fingers!

Director Yang didn't care about the small wound on his hand at all. He picked up the suture and put it on his nose and smelled it. A slight fishy smell entered his nose.

Even if Chen Changan's fish removal is thorough, the collagen extracted from the fish skin will still have a little fishy smell!

The moment he smelled the fishy smell, Director Yang understood that this suture was indeed made of collagen extracted from the fish skin!

He looked up at Chen Changan and said unacceptably: "You really created an absorbable collagen suture? Just those students who just graduated from school?"

Chen Changan looked at Director Yang's expression that looked like a ghost, smiled and shared something exciting with him.

"Director Yang, do you know how low it is to make a fish skin collagen suture line?"

"All chemical materials and fish skin consumables add up, excluding labor costs, each 100cm wire is only cost less than twenty yuan!"

"And if we expand the production line and use a large batch of chemical materials and fish skin consumables at one time, the price of the supplier can be lowered a little, at least to a production cost of 18 yuan per 100cm!"

When Chen Changan was choosing a plan, he took a fancy to the fish skin collagen suture at a glance because he didn't mention the simple production, but he estimated the production cost himself, which was also the cheapest of all plans.

But after it was really done, the cost was so cheap that it was beyond his expectations.

Originally, he estimated that the cost per 100cm should be 20 or 30 yuan, but he didn't expect that the actual purchase of raw materials would only cost ten yuan.

Moreover, if the procurement scale is expanded, the cost can be continued to be reduced to eight yuan.

Then he can sell for 40 or 50 yuan for 100cm, and sell for 45cm basic thread for 15 or 16 yuan, directly making the price to a point where it is two or three yuan cheaper than absorbable suture thread made by artificial chemical synthesis!

In this way, the absorbable sutures made by artificial chemical synthesis are no longer as good as the fish skin collagen sutures, and even the price is not as good as the fish skin collagen sutures. As long as the fish skin collagen sutures are on the market, the artificial chemical absorbable sutures will be finished.

......

Director Yang was even more confused when he heard this second bomb. The production cost shocked him even more. This was much lower than the production cost of other absorbable sutures!

He never expected that Chen Changan had just found 20 new employees, but in less than a month, he actually made the so-called fish skin collagen suture.

He always thought that Mr. Chen suddenly took office because he was young and energetic, so he wanted to do some new projects temporarily. He didn't know anything and was eager to do whatever he wanted!

So he always disliked Chen Changan very much, even hated him, and thought he was frivolous, self-righteous, ignorant, unrestrained, unsteady at all, and could not be a qualified boss at all.

But unexpectedly, Chen Changan had no intention of joking at all. It was not a temporary intention, but a confident one!

If the collagen suture really has so many advantages as Chen Changan said, but the disadvantages are only a little chemical residue that can be metabolized by the human body within three days, then the company will be rich, and the factory he is in charge may have expanded its assembly line crazily!

You should know that the natural collagen suture produced by Ranyuan Medical is only 15cm, 20cm, and 25cm in length, as well as the eighth specifications of Line 2 to Line 6-0, and the scope of application is very small.

However, in major hospitals in China, Ranyuan's natural collagen sutures are still popular, because only one company can do it worldwide. Ranyuan alone sells this product and has a net profit of hundreds of millions.

Because a 20cm collagen suture sold by Ranyuan costs more than 500 yuan!

On the one hand, it is because the production cost is too high, and on the other hand, the initial R&D cost investment is too high, so the price is so expensive.

Moreover, due to the production process, the collagen suture thread that Yuanmai cannot carry a suture needle when it leaves the factory. When it needs to be used, the doctor must tie the suture needle that meets the size separately!

You should know that when all other sutures are made into finished products, the manufacturer will bring their own suture needles. When it is needed, the nurse can just unpack and use them.

The fish skin collagen suture made by Chen Changan is not only very cheap to make! It also comes with a suture needle!

Even compared with absorbable sutures made by artificial chemical synthesis, the estimated cost is about the same.

Although the most expensive absorbable sutures made by artificial chemical synthesis are six or seven hundred, they are barbed sutures used to suture the uterine myometrium.

Generally, the basic 45cm surgical absorbable suture is only a dozen yuan for a basic model, and the production cost is only around the top, and the effect is incomparable to the collagen suture of fish skin!

Thinking of this, Director Yang raised his head and said excitedly: "Mr. Chen, give me half a month. I will definitely help you train all the workers and quickly enter the production of this collagen suture. As for other production lines in the factory, after producing the current order, they will all be replaced with suture production lines and no other products will be produced!"

Although he really couldn't understand why Chen Changan was able to make a brand new collagen absorbable suture in just over a month!

This is really against common sense. You should know that there are hundreds of suture production factories in China that can have this technology!

But! No matter what, Chen Changan has now proved that he can produce this magical product, so there is nothing to say. He must devote all his efforts to produce fish skin collagen sutures. This product can undoubtedly generate ten times more profit than low-grade consumables such as medical masks!

Other production lines can be completely abandoned!

Chen Changan looked at Director Yang's excited and puzzled expression and laughed in his heart. There was a bunch of black technology in his mind. If Director Yang could understand, it would be a real ghost.

"Very good!" Chen Changan nodded with great satisfaction, and finally got the stubborn Director Yang.

In fact, Director Yang has always done a good job. After all, from a normal mindset, no matter who is sitting in the position of director, he will probably stop Chen Changan.

At least, even though Director Yang was very unhappy and even did not understand what Chen Changan did, he did not make any trouble in private, deliberately making trouble and erratic disobedience. Chen Changan told him to buy the fish skin and chemical raw materials, and the quality was also very good.

Therefore, Director Yang actually did not make any mistakes. From his perspective, he was also in order to maintain the interests of the factory and confronted Chen Changan.

Now Chen Changan has used the finished product to prove that he really has the technology to produce fish skin collagen sutures, so Director Yang naturally became convinced and would not fight him.

After a brief excitement, Director Yang immediately said in a hurry: "Mr. Chen, then I will arrange it now and let the workers who participated in the trial production start training other workers in the factory to produce!"

His name for Chen Changan naturally changed from "Mr. Chen" to "Mr. Chen"!
