"Is this the first time I've missed?"

Zhang Xiaofan looked at Deng Xiaoni and Chen Ying standing in front of him, his face was full of unwillingness.

"Sure enough, don't go into areas you are not familiar with, because once something goes wrong, it will be a big problem. ”

Powder electrostatic spray guns are still problematic, and it is still a very fatal problem, selling nearly 500 electrostatic spray guns, and the problem rate is as high as 60%.

How long has it been?

In less than a month, the specific reason is that the immunity of the high-voltage electric generator to dust is too low, and the environment of powder coating construction can be imagined, and there must be a lot of fine dust, so there are indeed certain requirements for the roughness of the equipment.

That is, these equipment are required to have strong resistance to dust, take some precision equipment as an example, once the dust is excessive, it will cause a short circuit between lines, which will destroy the entire precision parts as a whole.

It's not that this powder electrostatic spray gun is not good enough, but because some parts of this spray gun are too tight, which leads to the contamination of the electrostatic spray gun to dust, which is very prone to problems.

Another is that the equipment is not designed to fully consider the isolation of dust, so when in use, a lot of dust will drill into the machine from the small gaps, and these dusts will cause damage to the inside of the machine.

The temperature of the electrostatic spray gun will be higher than the normal temperature when it is used, and the ambient temperature of the electrostatic spray gun itself is relatively high, and the high temperature is the natural enemy of many instruments and equipment, not to mention in the dust environment, so nearly 60% of the Zhimei electrostatic spray guns have gone on strike.

Some of them can't even turn on the power supply, some of them have problems with the high-voltage generator, and some of them have control errors, that is, when spraying, many times the air pressure is too large, or suddenly there is no air pressure, and all kinds of small problems.

Through the return of a spray gun for testing, Professor Qin's answer is that the closure is too poor, so the dust enters the machine, and then affects the normal operation of the machine.

Zhang Xiaofan thought it was a design problem, and then the two of them quarreled on the phone, which is not a quarrel! It's just that Zhang Xiaofan is refuting Professor Qin's statement, the relationship between the two is not very good, Zhang Xiaofan is a little unaccustomed to Professor Qin, and Professor Qin is not used to Zhang Xiaofan, so the two of them hung up without chatting for a few words.

"Mr. Zhang, it is normal for the new equipment to have problems, and there is no need to lose confidence at all. ”

"Heh, we don't need to say these things to each other, you know me, I think we can be more straightforward, this time it was indeed my mistake.

We should find some manufacturers to cooperate, at least those who have made achievements in this field.

The products designed by Professor Qin can definitely be said to be world-leading, at least in terms of energy consumption and saving powder coatings, which are very good.

But I think there's always been something wrong with her design philosophy.

The environment in which powder coatings are used must be full of dust, there is no doubt about this.

Even, because the workers are very rough when they use it, so many times the dust may be thicker than you think, and in such an environment, we need some rough products.

In fact, this is similar to the principle of large excavators, if you do it too finely, because of its harsh environment, it will definitely be easy to cause many parts to be easily damaged, the rougher the excavator, the more popular it will be, because it is not so easy to damage.

No one can guarantee that there will be no problems with their products, but the probability of problems is not necessarily too great, this time you take a look.

Our losses are definitely going to be very large, do you have any plans to deal with them?"

Zhang Xiaofan said to Chen Ying, this problem is actually the first problem to be solved at present, when receiving the call of the problem, especially after the continuous problems, Zhang Xiaofan immediately stopped the continued production of the factory, because the products produced will definitely be unqualified.

This is also to blame Zhang Xiaofan, during the experiment, Zhang Xiaofan personally operated, but he himself ignored a point, when he operated, the environment was actually very good, there was very little dust, and the automatic vacuum equipment was also very perfect.

But for manufacturers who use electrostatic spray guns, they definitely don't have such a good vacuum equipment, and they won't be like Zhang Xiaofan when operating, you must know that most of the workers never use their own things for the company equipment they use, so when they use it, the action may be relatively large, and when they use it, especially when they use compressed air, they will unconsciously clean up the machine, so that the dust inside the machine may be more.

"First of all, all our products will be recalled, and then we will compensate according to the price, and we will pay at least 50% of the cost for the lost time and products of our respective customers. ”

Compensation is a small matter, but the reputation that has been saved with great difficulty, and the reputation that has been saved with great difficulty, must be cut by at least half.

This is what Zhang Xiaofan can not accept, due to the different ways of problems with the electrostatic spray gun, so some manufacturers are large or small when using the powder, which causes them to complete the spraying, baking products, there are many defects, and they must be reworked, which causes material losses and labor and electricity losses, which must be borne by Zhimei New Materials.

This time, the loss will be at least tens of millions, which is not too much, but Zhang Xiaofan is uncomfortable in his heart, if he had been a little more careful.

Or when the electrostatic spray gun is unsalable, it can be reined in from the precipice, and in general, it will not have much impact.

That is now, as many as hundreds of customers, many of these customers are large customers of powder coatings, which will make them think, is there a problem with the powder coating provided by Zhimei New Materials?

You know, many people in the industry know each other, and then maybe when they are chatting at a party, they suddenly talk about it, although the consequences may not be very serious, but the seeds of doubt will definitely be buried in the hearts of others.

It takes a long time to build word-of-mouth, but if you want to break it, it's a breeze.

"Hurry up and deal with it, it should be our responsibility to take the initiative.

I'll talk to Professor Qin again, this time the responsibility is mainly on me, I didn't tell Professor Qin the environment in which this product is used, or I did underestimate the harshness of the environment. ”

Many people may not have been to the spraying factory, once you go in, you will find that whether it is on the wall or on the equipment, there is dust everywhere, and some will even be very thick, such an environment is actually very bad, and there is relatively large damage to the human body, not to mention the current workers, when they use protective equipment, they are always very casual.
