Small problems really cannot be ignored.

Li Wei has a deep understanding of this point, just take Cheng Xiang’s company as an example.

If you don't observe this kind of small problem carefully, it is sometimes really difficult to find.

Because on the surface it may be a small raindrop-like flaw, workers often selectively ignore it or simply fail to see it.

Then once this product is released, it will be bumpy during operation.

This flaw is highlighted when you arrive at the construction site.

Although it may be only a few, others may not think so.

He thought this might be a common situation, and then he sent the goods back in one sentence and you check it yourself.

How much does these losses cost?

The freight is manual in between, and then the time to screen defective products is screened.

The most important thing is the loss of credibility.

This is very deadly for a company.

Maybe after this batch of goods, you will have no chance of cooperation.

Never underestimate these things.

Some tricky customers or some very demanding customers, encountering this problem usually changes a supplier.

People who run companies know that there are some small flaws, which are really easy to ignore.

Therefore, once a problem is found, it must be solved in time and the cause must be found.

Otherwise, the losses will be greater.

"Is there any other problem?"

One person has gone to solve the problem, and the rest must have corresponding questions to ask and need to wait for Li Wei to answer.

"I have another problem here, which is actually a continuation of the previous problem."

"Oh?! Tell me!"

This actually made Li Wei's interest arouse.

The previous question actually continues.

"The last time I released a little too many defective items, as many as 100 pieces, so after leaving a few pieces, the rest will have to be reworked.

We polished these defective parts and then didn't do anything that was reworked, so we were thrown into the scrap pile."

Cheng Xiang was a little annoyed. No one reported this problem to him, and he didn't know.

More than 100 ceilings can be lost at will for him, and compared with the entire company's assets, it is a drop in the bucket.

What he was really angry about was this matter, he didn't even know.

And these management seems to be deliberately concealing them.

If this problem is expanded, will the future losses be greater? Will they also hide this matter?

This is why he was angry.

But now that Li Wei is present, he is not easy to have an attack.

It's just a serious face, and it makes people unable to tell whether it's happy or unhappy.

"Can you show it to me?"

Even if he didn't get the problem sample, Li Wei basically guessed what the problem was. He has encountered many such situations.

As Li Wei expected, it was a problem caused by digesting particles.

"Did you polish it with a hand grinder?"

"Yes, yes, is there any problem with this?"

"It's because of this problem. If you sand it with sandpaper, this problem will not occur!"

Everyone around me was puzzled. What is the reason?

Grinding with a hand grinder is both fast and convenient, while grinding with sandpaper is labor-intensive and efficient.

Why can't I use a hand grinder to polish the house?

"Powder coating is simply plastic particles, it is also a type of plastic.

We all know that plastics will coke when they encounter high temperatures.

The same goes for powder coatings.

You use a high-speed hand grinder to polish it, and it is obvious that part of it has changed due to the influence of high temperature.

It has been carbonized, or partially carbonized.

If I was not wrong about it, you should have polished such a little bit of small places.

No other place moved.

Moreover, you haven't polished this small area completely clean, and there is still a layer left on it.

Yes or no?"

Several people nodded quickly. In fact, they didn't know what was on it at that time. They just felt that it would be fine to grind this piece and then spray it again.

But who would have thought that the problem would become more and more serious, so after wasting more than 100 boards, they were thrown into the waste.

Because they can't solve this problem either.

Why does Mr. Li seem to be watching next to them at that time? Almost all the details are clearly stated.

This is really scary!

He seems to know exactly what you operated and what the result was.

Are young people so powerful nowadays?

"Why doesn't this happen if it is sanded with sandpaper?"

For some reason, suddenly Li Wei didn't want to say it.

I have actually said it clearly just now that high-speed manual grinding opportunities generate high temperatures.

Then it is obvious that sandpaper polishing will definitely not produce very high temperatures, it is just a little slower.

If they are powerful people, they will first use a high-speed manual grinder to polish it, but there are also skills in rubbing it. Grind it for one or two seconds, stop for half a minute, grind it for another one or two seconds, and then use sandpaper to polish it. This will not happen.

However, Li Wei does not recommend that people use this method. This method requires experience. Once it is not done well, the final result will not change, and it may be worse.

So let them be honest with sandpaper in the future, otherwise they will come to find themselves when something goes wrong, and they may not be able to come here to guide them.

"Because there is no high temperature!"

Cheng Xiang, with a serious face, suddenly said that he blushed a little for these managers.

I heard it clearly by the person I didn't come into contact with, but the man actually asked, really didn't know what to say.

But even if you choose a management, you have to watch it even if you feel disgusting.

"Mr. Li, what you mean is that if I polished it all, this kind of problem would not occur."

“Yes, if you use a hand grinder, be sure to polish all the paint that the hand grinder comes into contact with.

This problem will not exist if a whole board is polished clean, but if a little is left, such a volcanic pit may appear.

So the best way is to use sandpaper. Although it is a little less efficient, it can ensure quality and quantity."

This is Li Wei's suggestion. Whether they use it depends on their own.

Next, he asked a few more questions, and Li Wei also answered them one by one.

Many questions are relatively simple, of course, in Li Wei's opinion.

Because he has encountered many things, he knows what causes them and how to solve them.

This is the importance of experience. You may have encountered many questions, so it is more convenient to answer them.

However, as a technician, you will often encounter some problems you have never encountered before. This depends on your knowledge structure and your past experience to determine what is causing it.

Then, based on this judgment, make corresponding solutions and perform actual operations on the basis of the solutions.

If not, judge the problem from scratch.
