Some of the brand faces are straight and some are curved; Some are just plane layout, and some are blank strips on the back. Some have wide cards, and some have narrow cards attached to the main card. There are single ones and several combinations.
Cards are made of aluminum alloy with black plastic or white metal plugs at both ends.
The back is set off by plastic with the same shape as the card surface.
These plugs and foils are all injection molded, mostly from the south, and the prices are cheap.
What you can do is to make cards and screen print pictures and texts according to the contents and colors provided by customers.
Am I right?
You know, this kind of doorplate is installed in relatively high-end civilized units (banks, taxation, insurance, large companies, etc.). ), but also installed in the most conspicuous place, the same height as the observer's line of sight. If there are any defects, you can see them clearly.
Therefore, it is not easy to make a high-quality file! The difficulties are as follows:
(1) Layout processing.
The color of the layout must be uniform, and the painted paint will be elegant and beautiful;
Only by roughening the layout can we firmly grasp the pigment or ink and avoid curling, foaming, streaking and paint peeling.
(2) Fine layout.
Brands are mostly silver-white, and there are many kinds of silver-white, such as semi-bright, matt, big and small; Some are white, some are gray, and so on.
(3) Screen printing technology.
I don't want to say more here. You must think that you have mastered screen printing very skillfully. I just remind you: don't be too confident. In practice, you will be surprised to find out what kind of ink you use, what kind of mesh cloth you use, the number of times you apply photosensitive glue, the thinning and thickening of ink and so on.
(4) The main face of this sign is about 28 cm× 12 cm, and it needs to be printed in 3-5 colors. Some noodles are in stock, and more are the sizes required by customers. You must cut them into small pieces with large aluminum sheets and make them yourself. This will encounter a series of paint problems: paint selection, painting, baking and so on. The quality of this sign is very important. So paint technology should be used.
(5) Both ends of the arc-shaped card are bent and fastened on the card holder, and there is no such bending machine in the market.
Regarding the use of paint, you asked what is the difference between drying after painting and baking after painting. There is a big difference.
The curing of coatings can be divided into three forms: natural drying and curing; Curing agent curing; Baking and curing. In terms of fastness, baking is the strongest; As far as color is concerned, curing agent and baking are the best; From the point of view of cheap and labor-saving, natural curing is the best.
