The launch of a new product is often the result of thousands of experiments.

Even if this product has been mass-produced, it still needs to be constantly experimented, because you don't know when it will have some failures and some problems.

So when you use a certain product, this product brings you convenience in life, or a happy mood.

This product is not achieved overnight, but through the continuous accumulation of sweat of tens of millions of people, and slowly formed a mature product.

More than a month passed quickly.

The first to succeed was not Zhang Xiaofan's group, but the group led by Liu Qi.

Because they were developed earlier, and it wasn't very difficult.

A few days ago.

Liu Qi found Zhang Xiaofan and said that the products of their group had basically been developed.

Zhang Xiaofang is not surprised or surprised by this.

However, these things still need to be tested for themselves.

"How many do you make in one batch?"

Recipes made in the laboratory may have subtle differences once they are applied to actual production.

Therefore, once a new product is developed, a batch of Zhimei new materials must be produced on a large scale.

In order to verify this formulation, in actual production, the performance is not much different from that of the laboratory.

Or it is early detection that some problems may arise.

"A ton. ”

Zhang Xiaofan smiled, this is a very bold decision.

You must know that the cost of the wheel hub transparent coating developed by Liu Qi and them is very high, and the cost of one ton is close to 60,000.

However, looking at Liu Qi's very determined expression, Zhang Xiaofan was still very pleased, Liu Qi could be regarded as growing up.

The growth of a technician is not how skilled he is, but how much responsibility he can bear.

If this time, although Liu Qi's laboratory is successful, but when it comes to large-scale experiments, if there is a problem.

Then this batch of one ton of goods is basically invalid, and the loss is about 60,000 yuan, plus the loss of machinery, labor and electricity costs and management costs.

Although there is no need for compensation, if these problems really occur, Liu Qi's status in Zhang Xiaofan's mind will definitely drop a lot.

However, in this batch of large-scale experiments, Liu Qi still uses a ton of volume.

Then it proves that he is very confident, or he has done a small batch of large-scale machine experiments before, so that he has the confidence to conduct a large-scale experiment with a ton of quantity.

"You've grown a lot, you take five out of it, and I'm going to experiment with each of them. ”

Liu Qi blushed suddenly, and then in response to Zhang Xiaofan's words, he asked someone to go out to get the goods.

To inspect the transparent coating of the wheel, the hole card required is not any of the metals we commonly see.

Usually we test the quality of a coating, and the main bottom plate used may be aluminum plate or iron plate, or tinplate plate, or galvanized sheet.

This depends on the actual scope of the coating application you are making.

This time, Zhang Xiaofan used a mirror.

That's right, it's just to use a mirror as a substrate to test whether the transparent paint of this wheel hub meets the requirements?

Zhang Xiaofan knows, especially after so many years of technology, the general ordinary performance, basically no need to test, he will help you complete the test, this will definitely not be mistaken.

But at present, the most important thing to check for this wheel transparent coating is the transparency, and whether there are water spots, or some other defects such as small pinholes.

Transparency is one of the most important properties to measure the transparent coating of the wheel, the higher the transparency of the coating, the more transparent the whole contour can make the whole contour look more transparent, more full, and the metal effect is more charming.

So the best way to check transparency is to use a mirror.

This is a very good quality mirror that Zhang Xiaofan specially went to the market to buy, which can reflect the figure very clearly without any other flaws.

Cut them all into small rectangular pieces of 10×20 size, this is for ease of use.

Using our very common long tail clip, the glass mirror is clamped and hung into the spray booth.

When spraying transparent paint, there are many points that need to be paid attention to.

First of all, the electrostatic spray gun you use must be cleaned cleanly, without any impurities.

Any color of paint will be found once it is contaminated into the transparent paint, it is unusually obvious and can be detected at a glance.

Second, your bungalow also needs clean air, and it is easy to escape all kinds of impurities in the air.

Therefore, the spraying line of many wheel hubs is actually very, very clean, generally closed dust-free workshops, and even many large wheel hub manufacturers are operated by machines, and employees can only operate through glass.

Naturally, this thing can't be truly dust-free, but all kinds of pumping machines are still installed.

An excellent technician will definitely be an excellent spraying master at the same time.

A good technician, he knows the various properties of powder coatings very well, so they can use this kind of thing handy.

Just like when Zhang Xiaofan was spraying, his movements were very chic.

The electrostatic spraying gun was cleaned very carefully with compressed gas.

Then clean up the spray room, and finally Zhang Xiaofan put the mirror on the wire of the spray room.

Start with the electrostatic spray gun in an empty space, and then sweep it twice very seriously, two times up, down, left, right, and two times.

Zhang Xiaofan pays great attention to details.

After the spraying was completed, Zhang Xiaofan held it with his hand, and the mirror that had been sprayed with powder coating was sprayed, and then in the parallel direction of his eyes, he had to take a closer look to see if there was any very uneven situation.

If there are no blemishes, put it in the oven and bake it.

Bake the transparent paint at 200 degrees for 15 minutes.

When the time arrived, Zhang Xiaofan took it out and put it in a clean container to let it cool naturally.

Zhang Xiaofan looked at the glass mirror in his hand very carefully.

"The transparency is very good, the cleanliness is very high, but there are no water spots and no other blemishes.

We're experimenting with a few others. ”

Then Zhang Xiaofan drew a gourd and tested all five pieces of paint sampled at once.

After doing these things, Zhang Xiaofan said to Liu Qi.

"There are no problems with transparency and cleanliness, and the problems of water spots and blemishes are very small, so we can say that the quality of this paint is very good so far.

You're doing a great job.

In this way, you send our products to the testing institute at a speed and let them test all kinds of chemical and physical properties.

I need to see the results as soon as possible, and it's okay to add money. ”

Strengthening rapid detection of this kind of thing, Zhang Xiaofan has done a lot.

So even Liu Qi was not surprised by this kind of thing.
