In the blink of an eye, the weather in Shenzhen began to get hotter in early May.

Duan Yun installed several air conditioners for the research institute, and the staff dormitories were also equipped with electric fans, and the factory canteen began to distribute mung bean soup to the workshop every day, and watermelons were also bought and supplied to the factory workers for free.

Relatively speaking, Duan Yun's two factories are still very good, although Cheng Qingyan has been cutting the bonus treatment of workers since he became the manager, but in general, it is still better than other private enterprises, at least in terms of food and housing, the conditions are very good.

Yesterday at noon, when Duan Yun came to the electronics factory as usual, a truck slowly came and stopped in front of Duan Yun.

"Master Zhao?" When Duan Yun saw that the person who got out of the car was Zhao Changfeng, his face showed a little surprise.

"Manager Duan, long time no see!" Zhao Changfeng was carrying a large suitcase in his hand, and immediately greeted Duan Yun with a smile after getting out of the car.

The two have not seen each other for nearly half a year, and the last time Duan Yun went home after the Spring Festival, he did not pass by the Xiamen office, and usually only kept in touch by phone.

Today's Zhao Changfeng is a little thinner than at the beginning, dressed in a suit and leather shoes, with familiar black-framed glasses, his hair and leather shoes are shiny, and his face still has a somewhat familiar bookish atmosphere.

"Why didn't you make a phone call when you came? I can send someone to pick you up." After Duan Yun shook hands with Zhao Changfeng, he said to him.

"I only got the goods the night before yesterday, it was very late, I guess you have already slept, I know that our factory is in urgent need of these spare parts now, so I asked people to drive over the things overnight......," Zhao Changfeng said with a smile.

"Hard work!" Duan Yun glanced at the suitcase that Zhao Changfeng was carrying in his hand and asked, "This is the goods that our Gao family bought?"

Duan Yun previously ordered two batches of goods from Xiamen, one batch was ordered from Xiamen Yuanfang Company, which had been sent to Shenzhen half a month ago, and the second batch of goods was ordered from Xiamen's coastal villages and towns through special channels at a high price, including imported parts such as high-performance chips and small motors at the core of the current production line and plug-in machine.

"Yes, there are also three wooden boxes in the car with motors in them. Zhao Changfeng replied and glanced around.

"Come to my office and drive in. Seeing this, Duan Yun immediately motioned for Zhao Changfeng to come to his office with him.

Zhao Changfeng motioned for the driver to drive the car into the factory, and then entered the office area of the electronics factory with Duan Yun.

In Duan Yun's office, Zhao Chuanfeng opened the large suitcase, revealing an iron box inside, which contained circuit boards and chips, and in order to prevent bumps, the top and bottom were wrapped in thick sponges.

"Drink tea. Duan Yun made Zhao Changfeng a cup of tea, then squatted on the ground and carefully examined the things in the box.

Judging from the appearance, these chips are exactly the integrated circuits that Duan Yun needs, but I don't know if they can be used, and they still need to be tested.

It is very risky to buy these key components from Xiamen channels, and people who don't know how to do it are easy to be deceived, but Duan Yun's current situation can only bet that it is still unknown whether these chips can be used.

"There were also three motors shipped this time, and they were not unpacked when they were shipped, but judging from the nameplate of the machine, it should be the goods on the list. Zhao Changfeng took a sip of tea, and then said: "The people I know are still more trustworthy, but they are more reliable, and they all hope to continue to do some big business with us in the future......

"Master Zhao, we are a regular company, you must not involve yourself with these people......" Duan Yun said with a slight frown.

Zhao Changfeng is Duan Yun's right-hand man, and he is a little worried that Zhao Changfeng will cause some danger and trouble because of the gray channel.

"We are just buyers, not involved in smuggling, and these people have regular companies in Xiamen as a façade, and all transactions are carried out in accordance with legal procedures, so Manager Duan, you don't have to worry. Zhao Changfeng said with a smile.

Zhao Changfeng is still relatively shrewd in his calculations, he usually does these things through intermediaries, and he will not come forward directly, and now these gray channels in Xiamen have gradually changed their appearance, putting on the legal coat of "foreign trade companies", and some even have special Taiwanese businessmen to invest and register, as if they have become joint ventures, and on the surface they will do some legitimate business, and the local government also gives preferential policies.

"That's good!" Duan Yun nodded with satisfaction, and then continued to check the batch of chips.

After confirming that the quantity was consistent with the number on the product list, Duan Yun went to look at the three high-performance motors that had been shipped.

These three motors are also the key equipment for making plug-in machines, with stable performance and high precision, and they all come with corresponding speed control circuit boards.

Duan Yun prepared the first batch of three plug-in machines, if it can be successfully produced according to Duan Yun's design requirements, each plug-in machine is about equivalent to the work efficiency of 30~35 people, and the efficiency of three plug-in machines in one day is equivalent to the workload of more than 100 workers.

But in fact, the value of these three plug-in machines is much higher than 100 workers, and he improves not only the efficiency, but also the quality of the product.

There is also compared with general electronic products, the small tape recorder and walkman circuit board components developed by Duan Yun Electronics Factory are very dense, and the difficulty of manual welding is much higher than that of general circuit boards, and it is difficult to ensure quality and pass rate, which is a bottleneck in the technology of household electrical appliances, and with these plug-in machines, Duan Yun can easily break through this bottleneck, and at the same time, his products have a certain core competitiveness.

If it was in the past, Zhao Changfeng came to Shenzhen from Xiamen, Duan Yun would definitely treat him well, but this time it was different, Duan Yun had to race against time, install these key parts on the machine as soon as possible, and then test them.

Zhao Changfeng didn't care about Duan Yun's neglect, he also knew Duan Yun as a person, and it was a critical period to guide the company, and more than 2 million purchased parts and components must be put into use as soon as possible.

That night, all the technicians of the institute led by Duan Yun worked overtime overnight to test the new machine.

In the huge dust-free workshop, under the command of more than 10 technicians and maintenance section Yun, the plug-in machine was carefully assembled, working from noon to night, and consciously busy from night to early morning.

At this time, a touch of excitement flashed in Duan Yun's eyes, and at 4 o'clock in the morning, the machine was all assembled, Duan Yun briefly checked it, and asked the workers to carry the circuit boards and originals used for testing onto the conveyor belt, and then pressed the start button......
