Li Mao asked this question, and Liu Genfa couldn't answer him immediately. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

At this time, Liu Genfa was looking at the sample in his hand thoughtfully, knocking and breaking it with his hand from time to time, but there was still no breakage. This shows that the samples made by Huang Youyan this time are indeed qualified products.

Huang Zubin, who was standing behind him, was excited at this time, and he quietly said to Huang Youyan next to him: "Son, you have made a great contribution this time, and you have solved the quality problem that the whole company can't solve." ”

After speaking, he also stretched out his palm, attached it to Huang Youyan's ear, and whispered to him: "You are more powerful than Director Li!" ”

After speaking, Huang Zubin laughed to himself.

Huang Youyan glared at him and whispered, "Dad, don't talk nonsense." ”

Huang Youyan knew that he had a few pounds and a few taels, and he didn't take Huang Zubin's words seriously at all, but felt very embarrassed by his father's boasting.

Where did he solve any quality problems, he just happened to make samples, and there were no quality problems.

In other words, the product made has no quality problems, isn't this the way it should be?

Huang Zubin didn't realize this, and in his heart, he was still complacent that his son had solved this problem, which the whole company couldn't solve. Don't look at Li Mao, he is fierce on weekdays, won't he be able to solve this problem this time? It's not as good as his son.

Unlike Huang Zubin's secret happiness, Liu Genfa and Wan Yuhan both frowned, not understanding why Huang Youyan used the same method to start the machine this time, but the products made by Huang Youyan were qualified.

"Huang Youyan." Liu Genfa raised his head and shouted Huang Youyan.

Huang Youyan, who was leaning in front of her to take a closer look at the sample, immediately raised her head and responded: "Hey, what's wrong?" ”

"When you made products before, was there any difference from this time?" Liu Genfa asked.

In fact, when Liu Genfa asked this question, he didn't have much hope, he knew that with the cognition of a small employee of the production line, I am afraid that it would not be possible to analyze what changes would occur between several time periods.

Sure enough, Huang Youyan shook his head: "It's no different, I usually do this, turn on the machine, take samples, and pack ......"

After thinking about it, Huang Youyan's eyes lit up: "Oh, if there is really anything different, that is, when I was on the night shift before, this machine was always on, this time, it was stopped for several days, and it had to be warmed up for 20 minutes today." ”

"Warm up?" Liu Genfa muttered thoughtfully.

However, he still didn't figure out anything from this small change, so he could only look back at Wan Yuhan, wanting to see if Wan Yuhan had found anything.

At this time, Wan Yuhan was also frowning, thinking hard, and when she saw Liu Genfa casting her gaze, she immediately asked, "Will it be ...... Is it temperature-influenced? ”

"No, it won't." As soon as she finished speaking, several other people replied almost in unison.

At this moment, Wan Yuhan's face couldn't hold back, his face turned red, and he wanted to stop there, so as not to expose his ignorance, but after all, he still couldn't suppress the strong desire for knowledge in his body, so he asked, "Why?" ”

"Because, the temperature is controlled by setting the parameters on the machine, and if the parameter settings do not change, then the temperature will not change. And...... If there is a difference in temperature, then the structure of the product will also change, and the impact will not only be a problem of fracture. Liu Genfa explained.

Of course, he also noticed Wan Yuhan's embarrassment, but what made him feel relieved was that Wan Yuhan did not give up his quest for knowledge because he was afraid of her face.

Liu Genfa was very satisfied with Wan Yuhan's performance, so regardless of whether he was working on the supplier's site or not, he immediately turned on the teacher-student mode to answer Wan Yuhan's questions.

"I see, I see." Wan Yuhan nodded and said thoughtfully.

Although, for what Liu Genfa said just now, it is impossible for her to digest and absorb them all in a short time, but she has a general understanding, that is, if the temperature changes, there will be more aspects that affect the product, not just breaking.

Liu Genfa saw that Wan Yuhan seemed to understand a little, so he turned his head and continued to ask Huang Youyan: "Aside from this, is there anything different?" ”

Huang Youyan shook her head: "No, there is nothing different about anything else." ”

Liu Genfa saw that from Huang Youyan, he couldn't ask for any useful information, he turned his head and looked at the plastic molding machine in front of him.

I saw that in front of me was a 5-ton molding machine, a German brand, although it has been a long time, but the surface still looks very new, and the accuracy is also very well controlled.

Liu Genfa carefully observed every part of the machine and found no problems, which shows that it is not the problem of the machine itself, then, the place where the problem will occur must be the place that can be affected by human factors.

Liu Genfa recalled in his mind again: Human-machine-material law ring, where did I neglect these aspects?

Thinking about it, Liu Genfa's eyes suddenly widened, and he turned his head and asked Huang Youyan: "Did you add recycled materials to the raw materials today?" ”

Huang Youyan was asked suddenly, a little stunned, reacted, moved up and down her throat, swallowed her saliva, and then said: "No, it's not just started, there is no recycled material to use." Though...... Although it is written in the table that 20% recycled material needs to be added, when there is no one, I can only use 100% base material. ”

Huang Youyan explained hesitantly, but Liu Genfa's eyes became brighter and brighter.

Liu Genfa: This time there is no added recycled material...... 100% base metal is used, whereas before ......

Li Mao, who was standing on the side, seemed to have heard some clues, but he never caught that point, so he asked Liu Genfa on the side curiously and confusedly: "Master Liu, there is nothing wrong with this, when there is no recycled material, you must only use all the base materials." 100% base metal, better than the ratio we require, for the product. ”

This does not need to be explained by Li Mao, of course Liu Genfa knows that 100% of the base metal is compared with 80% of the base metal and 20% recycled materials, of course, the products made by the former are better.

In other words, the reason why the samples made today have good appearance and performance and are qualified products is because 100% of the base material is used. The previous product was unqualified because of the addition of recycled materials, as for whether 20% was added...... I'm afraid that only Huang Youyan in front of him can tell everyone.
