Xu Hongwei was attracted when he first saw the magic curtain products that year. He realizes that this is a technology product with great market prospects.
A month later, he decided to invest and became an angel investor in the project.
That year was 2012.
What is the magic curtain?
In fact, it is very simple to say that it can change the permeability of the film.
That is to say, according to the needs of users, it can be as transparent as ordinary film stickers, or instantaneous atomization, can not see the scenery beyond the film.
At first, Xu Hongwei's idea was to promote this kind of "magic curtain" product in the field of architecture, so that every glass window can be switched between permeability and atomization at will, and whether the sunshine sprinkles into the room depends on the mood, isn't it beautiful?
 

It happened that a friend was making a new energy car, so he began to try to make this magic curtain on the car.
Then it fell into the pit.
It is much more difficult to put film on cars than on buildings. Because cars have radians, and the glass of buildings is basically flat.
The technical principle of "magic curtain" is not difficult to understand: adding polymer materials between the two layers of membranes, according to whether electrified or not, to change the structure of polymer materials, thereby realizing the change of permeability.
The difficulty is how to thin the film.
At first, the magic curtain was very thick. As a result, it is impossible to fit the curvature of the car glass.
Therefore, after tackling key technical problems, the thickness of the product is finally reduced.
However, durability has deteriorated.
We can only tackle key problems with a hard head.
After making thin and durable, it is necessary to achieve high permeability.
Fortunately, the friend gave him and his team enough patience. Let them make progress in solving problems continuously.
It has now achieved a thickness of only 0.11 mm.
"We eventually decided on four styles, but the process is not known to outsiders, it may take 20 rounds of continuous upgrading to come today." Xu Hongwei said.

I believe that those who have done product research and development will know the difficulties behind this sentence.
The product can finally be brought out to meet people, but where the customer is, has become the next problem to be solved.
Although friends can allow them to constantly make mistakes, but to truly land on automotive products, but to follow a standardized bidding process.
As a result, Xu Hongwei found that they will face a direct competitor, but it is a well-known domestic automotive glass supplier.
Originally thought that facing a strong opponent, will be a difficult barrier to cross, it seems that in addition to the offer to give greater concessions, there is no other way.
Unexpectedly, however, competitors have never been able to develop similar products. The end result is that both sides become partners.
Xu Hongwei said that this is called "no fight no acquaintance".
However, this result really changed Huahui's original market thinking. At first, they wanted to face the automobile manufacturers directly, but later found that if they positioned their customers as automobile glass suppliers, it would be more conducive to the development of enterprises - greatly shortening the cycle of account recovery. The importance of cash flow to start-up companies can be imagined.
It is precisely the change of this strategy that has put Huahui on the path of steady growth.
Although the focus of current development is on automobiles, Xu Hongwei believes that more application scenarios of magic curtain will be discovered when technology and products are mature.
For example, if it is used in unmanned vending machines, it can realize the switching of container glass between the projection background and the transparent glass. When users stand in front of them, they can see the goods in the cabinet. If there are no users, the whole vending machine will become the display background to broadcast advertisements.
In agricultural production, the magic curtain can also be used as a window to observe the production environment.
At present, Huahui hopes to be able to make initial financing, 5 million to 10 million yuan, and sell 10% to 20% of its equity. Xu Hongwei hopes to be able to obtain funds, in expanding production capacity, training skilled technicians and market promotion to get a boost. It is also hoped that under the injection of funds, Huahui will be able to provide services for more automobile brands and form faster growth.
