"The first step in making the electric version is to copy, after the copying is done, I need to use high-tech means to print the pattern to the metal plate one by one, so the selection of the metal plate is very important, stinky boy, you see, it is different from ordinary iron sheets."

Li Wen pushed the glasses on the bridge of his nose and leaned closer to the hanging metal plate to take a closer look.

"Uncle Xin, the color of this metal plate is green, it doesn't seem to be a simple piece of iron, it must also have copper added to it, its cross-section is reflective, it may be zinc, it may also be aluminum, it is an alloy...... Uncle Xin, can I touch it? ”

Uncle Xin smiled and nodded.

"The surface is smooth, it needs to be plated, the ductility is good, it can't contain manganese when forging it, and the temperature can't be too high...... Uncle Xin, it's not easy to get this metal plate, you must have spent a long time, right? ”

Uncle Xin shook his head with a smile, "I didn't spend a minute, I just need to write the specifications and detailed parameters to the eldest niece, and the eldest niece will naturally go to the manufacturer, and the manufacturer will get it out according to the requirements, just pay a little more, and the problems that money can solve don't need us to be the master ourselves." ”

Li Wen knew it in his heart.

Uncle Xin pressed the button, and an electronic instrument above immediately emitted a bright light, projecting the overall size of the banknote onto the metal plate according to the original proportion, cutting off the excess along the light, and a motherboard that was exactly the same size as the banknote was freshly baked.

Uncle Xin clamped the motherboard to the turntable with an iron tong wrapped with cotton cloth at the tip, and fixed it on all sides with a soft clamp, turned on the power supply, and the motherboard rotated in a counterclockwise direction at a uniform speed.

"Stinky boy, there is a saying you should have heard, called the predecessors planted trees and the later people enjoyed the shade, it is time for you to enter the industry, the equipment is ready-made, you just need to learn how to use it, unlike me before, when I used to be with the young master and father, that is the real ...... from scratch"

Uncle Xin said as he turned on the switch, and the nozzle immediately squirted out a blue liquid and sprayed it onto the rotating motherboard, which gradually changed color and turned vermilion.

"On the way to batch printing, the temperature will gradually rise, and once the temperature is high, it will have an impact on the motherboard, so the motherboard must also be quenched before rubbing to make it resistant to high temperatures. The sprayed coating has a catalyst in it, and before quenching, let it undergo a chemical reaction......"

Uncle Xin took out the motherboard sprayed with the coating and put it on the fire rack.

"Optical principles, chemical reactions, we can all measure them, and it is not a problem to measure them, but how much fire is used for quenching and how long it takes to bake depends on experience, and the heat is to be grasped by yourself," Uncle Xin patted Li Wen's shoulder, "Young man, study hard, there are still many places you have to learn." ”

As he spoke, the motherboard had been quenched, and Uncle Xin took it off.

"After quenching, we also need to anneal, this step is also very important, it will affect the service life of your motherboard, how much water to use, also very knowledgeable."

Uncle Xin turned on the faucet, and water immediately flowed out of the leather pipe.

Uncle Xin spread out his palm, let the water flow on the palm, closed his eyes, felt it, and adjusted the water valve while feeling, until the water flow became not big or small, just right, and then nodded with satisfaction.

Seeing that the steam of the motherboard was getting smaller and smaller under the washing of the water, until it disappeared, Uncle Xin turned to Li and asked: "Nothing in terms of experience can be learned in a day or two, but as long as you are willing to work hard and are willing to feel with your heart, then no difficulty can stump you." ”

"Actually, the most important thing for us to be masters is to have good craftsmanship, as long as we are calm, we will not get into trouble, do more and learn more, young man, your future is immeasurable, and the eldest niece is also good to you, if you can ...... Ahem, when the time comes, they will all be a family, and their brothers and sisters will definitely hurt you even more. I'm just old, I hope you kid will take over my shift soon, and I can retire early and enjoy happiness. ”

"Uncle Xin, where do you want to retire? Your family, I've never heard you mention it, and besides, is your surname really Wu? ”

"Stinky boy, why do you care so much? Don't you know that there is another rule of conduct, that is, one less person knows, and one day longer, understand? ”

"I'm sorry, Uncle Xin...... I ......"

"Take it."

Only then did Li Wen notice that a wallet was suddenly stuffed in his hand, and there was a photo in the wallet, in which Uncle Xin was surrounded by one big, four small, and five women.

"The five flowers of the Zhang family, beautiful, right?"

Li Wen was amazed, the older woman should be Uncle Xin's wife, and the other four little ones must be his daughters, but they didn't expect that the four daughters born to Uncle Xin, a bad old man, were more beautiful than the other.

"They only know that I run a watch shop abroad, and nothing else."

"Uncle Xin, I don't know if I should say it or not."

"You kid have something to say quickly, and if you have a fart, let it go."

"That...... Uncle Xin, are you recruiting a son-in-law? Four QR codes! ”

Uncle Xin was stunned for a moment, and suddenly punched Li Wen, who immediately dodged with a smile.

"Okay, you stinky boy, now even Lao Tzu dares to use it to make fun, no big or small!"

Li Wen threw the wallet back, "Uncle Xin, just kidding, smile for ten years." By the way, Uncle Xin, it turns out that your surname is not Wu, your name is Zhang Xin. ”

"Isn't your kid not surnamed Wu? Are you really called Wu Fusheng? True or false, just have a number in mind. By the way, now that the motherboard is almost ready, we can try to print a few copies tomorrow. ”

"Okay, I wish we all the best."

The next day, when the weather improved, Li Wen took his washed clothes and pants to dry on the horizontal bar next to the bunker.

"Stinky boy, come here!"

Uncle Xin stood at the door of the workshop and waved.

"Here we are."

Li Wen threw the plastic basin into the house and trotted over.

"Look, what about our first print?" Uncle Xin spread a piece of paper in front of Li Wen, and on the paper was a row of banknote patterns.

Li Wen picked up the magnifying glass and took a closer look, "Yes, Uncle Xin, it's perfect, it doesn't even have a moiré pattern, if you get it on the market without going through the money detector, you can't tell it by the naked eye alone." ”

"Stinky boy, your requirements are too low, let's do it like a real painting, we have to be exactly the same, do you understand?"

"Of course I know, but as far as I know, the money is printed on acid-free paper, and the printing press is also a gravure printing press, which is the right of the state to use......"

"Stinky boy, remember what I told you before, the problems that can be solved with money are not problems, acid-free paper and gravure printing presses, I believe that the eldest niece and the young master will definitely have a way to do it, let's just wait to use the ready-made ones as masters...... Take advantage of this time, let's improve the electric version again, print more on ordinary paper, make sure that there are no scratches, no other problems, and everything will be fine. ”
