Li Mao spoke on the stage, and Liu Genfa listened carefully in the audience, and the more he listened, the tighter Liu Genfa's brows wrinkled. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

To solve this quality problem, it is nothing more than to start from five aspects: man, machine, material, method and environment.

People: Workers who are directly related to the product.

For this point, Li Mao and they have already done an investigation, and the staff who made this product has not changed. Then this one reason is ruled out.

Machine: The machine from which this product is manufactured.

For this point, Li Mao and they have done a lot of investigation to determine the parameters of the machine, temperature, time, etc., but there is no point of change, that is to say, the machine has always remained in the same state, but the product has changed, from the original non-break, to the current break. This shows that the cause of the fracture has nothing to do with the machine itself.

Material: The raw material from which the product is manufactured.

When it comes to this, Li Mao is a brush-off: "For the raw materials, we have also confirmed that they meet the technical requirements we have specified. Next, let's talk about the method of manufacturing products......"

Hearing this, Liu Genfa interrupted Li Mao: "Wait a minute, I have a question. ”

"Master Liu, please speak." Hearing Liu Genfa's question, Li Mao immediately stopped his words, respectfully stretched out his hand, and motioned for Liu Genfa to speak.

"We all know that when manufacturing plastic products, it is impossible to use 100% of the base metal particles in the warehouse for raw materials, and some recycled materials will be added. Liu Genfa asked.

Liu Genfa's questions were too professional for Wan Yuhan, she hurriedly took out her small notebook, and wrote down these questions on it, planning to ask Liu Genfa separately after the meeting: What are base metal particles? What is recyclate? What is the correct addition ratio?

Li Mao hurriedly replied respectfully: "Yes, Master Liu, you are right. All plastic products are added with recycled materials during production, and the recycled materials added to our products are also in line with the proportion, our proportion is 20%. ”

As soon as Li Mao finished speaking, Wan Yuhan couldn't help but whisper to Liu Genfa on the side: "Master, is their ratio normal?" How much is appropriate? ”

In fact, after Wan Yuhan asked this sentence, he did not expect Liu Genfa to answer him immediately, but fortunately, Liu Genfa immediately turned his head and whispered to her: "Generally speaking, the proportion of recycled materials is not more than 30% of the raw materials (that is, the base materials). Their addition ratio is in accordance with the regulations and is normal. ”

After speaking, Liu Genfa didn't look at Wan Yuhan, but turned his head to Li Mao and nodded: "Okay, I don't have a problem, you can continue to talk about it!" ”

At this time, Wan Yuhan was in turmoil, she didn't expect that Liu Genfa would be so attentive to the questions she asked, regardless of the ongoing meeting, and answer her questions first.

This master is simply amazing, isn't it?

Wan Yuhan secretly swore in his heart: I must study hard, I must live up to my master's expectations of me, and I must not embarrass him!

Thinking like this in his heart, Wan Yuhan lowered his head and wrote down what he had just learned from Liu Genfa in his notebook: the proportion of recycled materials.

Then Li Mao began to introduce the 'Fa'.

Method: The method of manufacturing a product.

For this, in fact, there is not much to study, because it has been said when the machine was introduced before, the individual parameters have not changed, so the method is naturally fixed, and there is not much possible change.

Sure enough, Li Mao said: "We have also confirmed the method, it is exactly the same as before, and there is no change." ”

Ring: The individual elements related to the manufacturing of the product, the environment in which it is located.

Li Mao is not too sure about this: "As far as the environment is concerned, because there are too many variables, what we can determine is relatively limited, so we can't say 100% that there is no change in the middle." However, as far as we can see a few key points, there is indeed not much change, and the key points we confirm include: the environment in which the raw materials are located, the environment in the process of handling raw materials, the environment in which the machine is located, the environment in which the products are manufactured, and the environment in which the products are located after the final packaging is completed. ”

After listening to Li Mao's words, Liu Genfa's brows furrowed even tighter.

Li Mao's analysis is very comprehensive and his confirmation is also very detailed. Judging from the results he confirmed, the product should not break! But now the product is actually broken, and it is in batches, breaking in the same place...... This shows that there are still some points of change that have not been found by them.

If the cause cannot be found, the so-called solution that is determined will of course not have a practical effect.

Liu Genfa was thinking about it in his heart, and Li Mao couldn't wait to ask, "Master Liu, do you have any thoughts after listening to this?" If there is anything unclear, feel free to ask me. ”

Liu Genfa nodded: "What you just said is already very clear, thank you!" Let me think for myself first, is there anything else else I would like to introduce? ”

Liu Genfa's last sentence was a bit anti-guest-oriented, and his eyes swept around the entire conference room, only to find that everyone was just looking at each other, with an embarrassed look on their faces. It seems that they don't have anything else to explain.

Liu Genfa took a deep breath, stood up and said, "Okay, since you don't have anything else to introduce, let's go to the scene and take a look!" ”

After speaking, Liu Genfa turned his head, looked at Wan Yuhan and said: "To investigate the cause of quality problems, we must follow the principle of three appearances: scene, present, and reality. So we're going to go to the scene now, let's go! Li Mao, you lead the way in front! ”

Liu Genfa was not polite, and directly used Li Mao, not polite to him at all.

Li Mao was very happy with Liu Genfa's self-cooked arrangement, and quickly nodded and said, "Okay, you come with me." ”

After saying this, Li Mao realized that there were still senior leaders of Huarong Company in the conference room, so he looked at the leaders with some embarrassment and said: "Leader, then we ......."

Li Mao is now going to take Liu Genfa to the scene, the so-called site, that is, the workshop manufacturing site. The workshop is generally dirty, messy, and noisy. I'm afraid that the company's senior leaders are reluctant to go to the workshop site, but it doesn't seem good to let them stay in the conference room and wait. Therefore, Li Mao was a little embarrassed for a while.
