This swivel chair is so comfortable! The touch of this leather is like a woman's skin!

After completing all the formalities, Qin Feng sat on the wide chair, very satisfied, such a small room is actually more like an office, but if Pacific Trading Company can gain a foothold here, it is the top company in the country!

Zhao Jiao was also very excited, at this time she was holding a rag and wiping it around, with pride and pride on her face.

It's all like a dream, in the past two months, she has experienced too many things, and now she has truly become an urban beauty.

"Zhao Jiao, you will work here in the future."

"Hmm." Zhao Jiao nodded: "Brother Feng, what about you?" ”

"Me? We're definitely going to come together, we're going to go together. Qin Feng said: "Our Pacific Trading Company starts from here, will go to the whole country, to the world, in the future in New York, in London, in Paris, in such a similar high-end office building, there will be our company's brand!" ”

"Uh-huh." Zhao Jiao nodded again and again, even if Brother Feng was bragging, she would take it seriously, after all, Brother Feng had already created many miracles.

"Brother Feng, what are we going to do next? Do you have to get in touch with that Imai Castle? ”

"Well, then what are you waiting for, the next development of the company depends on you." Qin Feng shook his hand at the shopkeeper: "Look at him in China, or if he has already gone back, fortunately, he can make international calls here, and he can call them at any time." ”

It's still inconvenient in the era of no mobile phones! In November 87, the south had the first batch of big brothers, and if you want to get one, you have to wait for a while.

Zhao Jiao called the hotel first, and sure enough, the person had already left, and it was time to make an international call, but she didn't make a move, and looked at Qin Feng: "Brother Feng, I don't know Japanese, I will study hard." ”

"Okay, I'll do it."

As he thought about this, he dialed the number and quickly spoke.

"That's right, Mr. Imai Castle, it's me, Mr. Qin of Pacific Trading Company."

"Dad, I'll do it." Qin Feng took the phone, only listened to two sentences, and was stunned: "Mr. Imai Castle, do you still want to order the second batch of coffee beans?" Absolutely! Ten times as many as last time? Of course, you can, but if there are more of them, the price will have to rise, why? Because the sunspots don't like to do the same thing all the time, they're already annoyed and asking for a salary increase! ”

"What, you're coming to us in three days? Okay, I can't say it on the phone, three days later, my company, the address is in the Chocolate Building, that's right, it is the most expensive office building in the capital, the office location of our Pacific Trading Company, meet and say, good, good, see you or leave. ”

"Make a few more phone calls, contact everyone who should be contacted, and then we'll go back to make samples." Qin Feng said: "Come back in three days, we have to recruit someone to sit on duty in the future, let's talk about it later." ”

The next day, the galose factory.

"Here you go, we've made the uppers, but this thing is too wasteful of materials!" Qin Jianguo held an upper designed by Qin Feng in his hand and said to Qin Feng.

The front of the upper is made of black cowhide, and in order to reduce the weight, the toe cap is not lined with steel plates, and the cowhide extends all the way to the back heel, then the front lace and other parts, and the rest of the ankle wrap is still made of canvas.

Canvas is actually not to reduce costs, mainly to breathe, after all, these shoes are to be worn in the south, they are all leather to cover the feet, there is no mesh shoe material in this era, and Qin Feng does not pay attention to those red tape.

"But are you sure this upper is okay?" Qin Jianguo continued: "There is no place for the suture line on the upper, what do you do to combine the upper and the sole? ”

"How to do liberation shoes, let's do it."

The connection between the upper and the sole is also exquisite, the liberation shoes are ordinary rubber shoes, directly fuse the rubber into it, and stick it together with the upper, but this is only the practice of rubber shoes, the general leather shoes, are stitching process, the sole and the upper are sewn together.

Qin Feng wants to use the process of rubber shoes on leather shoes?

"Dad, just watch it." Qin Feng said, put the upper on the mold, fixed it, and then inserted it into the mold below.

"First of all, let's inject the rubber first." Qin Feng said and began to rotate the spiral injection device.

"That's it?"

"Of course not, and then we need to inject the PU foam layer."

"What do you mean? Two layers of bottoms? What is skin oil? Is it sturdy? The army wears it, and if there is a quality problem, it is a big deal! ”

"Don't worry."

In the modern shoe-making process, the technology has long been developed, the simple sole is also divided into three layers, the outermost is the rubber layer, strong and wear-resistant, anti-slip and tear-resistant, the inner layer of rubber is the foam layer, soft and comfortable to wear and shock absorption, so it is called dual-density sole, at the same time, these things are directly adhered to the upper after injection, and the whole process is called dual-density joint injection process.

This can be operated manually, but it is very cumbersome, the failure rate is very high, and it still has to be automated machines, and Qin Feng asked the university to help make this thing.

Isn't the sole three-layered? Of course, there is also a layer of insole, or leather bottom, which is a puncture-resistant aramid material, which is glued underneath it and combined with the shoes underneath.

PU sole is also a common material, the scientific name polyurethane, was invented by the Germans in 1937, and began to enter the civilian shoe market around the seventies, which is lighter and softer than rubber, with high strength, oil resistance, abrasion resistance and tear resistance.

Of course, this thing also has defects, once exposed to the air, it is easy to undergo chemical changes and lose its original properties, so it needs to be wrapped in rubber, and some manufacturers in later generations only use PU as a material to make soles, shoes are more lightweight, but they can only be worn for one year.

Qin Feng first injected the rubber layer, and then continued to inject polyurethane materials, compared with automated machinery and equipment, the biggest problem with manual injection is not knowing how much to inject, it is completely estimated.

"Okay, it should be about the same." Qin Feng is also tentative, but, after all, there is a foundation for later generations, he once participated in the research and development of 97-style military boots, and when he first made sample shoes, he used this kind of manual process, so although he crossed the river by feeling the stones, he still had a certain certainty.

"That's it?" Qin Jianguo was very surprised on the side.

"Of course not, it still has to be heated, vulcanized, etc., a set of processes are down, it will take about half a day." Qin Feng said, starting the electric heating in the mold.

There is no temperature control for this, and I also estimate it myself.

Ten minutes later.

Qin Feng opened the mold and took the shoes out of it.

The sole is very thick, with a large mahjong block like a pattern, at first glance, the anti-slip performance is outstanding, and there is a rubber layer between the sole and the upper, which looks very strong, Qin Jianguo wanted to reach out and touch it, but was stopped by Qin Feng.

"Don't worry, it's not done yet, the next process!"
