Blister word is a kind of luminous word, which is absorbed on the surface of the mold by vacuum, flattened the hard plastic sheet, heated and soft, and cooled after forming. It is made of plastic processing technology. Jinan billboard is widely used in plastic packaging, lighting, advertising, decoration and other industries. Blister light-emitting characters are usually composed of blister panel, aluminum-plastic edge, metal substrate and LED light source.
1. LED light source
According to the angle of the light, the LED light source has flat head and round head. The light angle of the flat head is larger, and the brightness in front is not as bright as that of the round head; this round head is just right. The latest generation of light source used now is SMD lamp. The biggest feature of SMD lamp is high brightness and small light drop.
2. blister plate
The blister board is a part of the blister luminous characters. The common practice is to use the engraving mold (upper and lower mold) of the density board to bake the soft pressed plastic after pressing. Foam lettering is directly carved into a word with the power of acrylic acid, which makes the mask of acrylic acid shine directly. This is also a lot of previous saying, although acrylic light box characters have no three-dimensional sense, they also have a good effect with the color matching of the edge of baking paint. The advantage of the light box character is that it can make the signboard character have spirit and horn. Generally, foreign customers prefer sign language with spirit and horn.
The blister character board can also be made into a sphere and a diamond. These are just the functions of the mold. What kind of effect is it after blister, so the production of the blister character mold is also very important. Thickness of blister - the thicker the blister, the more stereoscopic the character. Generally, the thickness of the blister is 2-3cm, which is the most appropriate, and the height of 2cm is also OK. It is worth mentioning that the blister should not be too thick. It's easy to draw the thin acrylic plate at the height of inhalation, resulting in insufficient strength, and even some color changes caused by the pressure of acrylic plate, such as some blue or green inhalation, will become white traces, resulting in poor lighting effect.
3. Aluminum plastic edge
Blister word binding is the first use of aluminum-plastic edge, which is the easiest way to make Blister word. Small bubble words are generally made in this way, and big bubble words are not recommended to use this structure. The choice of aluminum-plastic edge needs to choose a good material. Many recycled materials will soon fade and age. At last, they are easy to be blown away literally. There is a box at the bottom on the wall, which is often seen.
In general, we suggest to use metal edge for big bubbles, which is firm and beautiful, and increases the three-dimensional feeling. This kind of Blister word is similar to the structural word of the lamp box. It is carved metal edge covered with hollow blister panel. We call it blister in this word. It is commonly used for galvanized metal sheet, titanium gold, stainless steel, aluminum, etc.
4. Metal base
There is a base for blister words, which can be installed with LED lights. The basic practice of blister words is similar to that of paint. On the basis of key points, automobile paint must be used, otherwise the paint will fall off soon, the iron sheet will rust soon, and the rusty water will flow into the beautiful influence of blister words. In addition, PVC bottom box can be used for small type and iron plate bottom can be used for large type.
