Blister light boxes are the easiest to see no matter day or night. Most of the store signs use blister light boxes. Compared with other light boxes, it has many advantages that other light boxes cannot compare. The specific advantages are as follows.

Blister light box is a widely used light box made of acrylic material, which has developed rapidly in the past two years. It is mainly used outdoors, often used as shop signs and billboards, and you can see it everywhere on the street as long as you pay attention.

The application of blister light boxes in stores such as "McDonald's" has played a good demonstration role. The acrylic blister overall identification system of Sinopec's gas stations is applied, and the blister light boxes in terminal stores of major mobile phone manufacturers are displayed in creating good advertising benefits for manufacturers. At the same time, it has played a role in promoting the application of acrylic plastic light boxes in the market. Acrylic blister light box has become another new bright spot in the advertising production industry after neon lights, inkjet printing and engraving. Together with the ultra-thin light box, it constitutes the mainstream product of the advertising light box.

Blister light box three-dimensional luminous character processing technology - due to the stable quality of acrylic, its products have good light transmission, clear farsightedness, high compressive strength, no fading for more than ten years, bright as new and other light boxes, metal characters The incomparable characteristics make it the first choice for businesses with sustainable operation and strong strength. From multinational companies such as McDonald's, KFC and Pizza Hut, to domestic supermarket chains, banks, and Jiefang Commercial Vehicle Service Center, there is a huge business opportunity for advertising logos. Acrylic processing is inseparable from the mold. The mold can be made of wood, gypsum, steel, etc., and the selection of mold materials can be determined according to the processing batch. The wooden mold saves costs and is only suitable for small-scale processing, because it will lose water and deform after being used for a long time, and the finished product will naturally be unsightly, and it will also bring trouble to post-production (need to be processed). The pre-production of the blister light box and the three-dimensional luminous characters is the same: film making → heating (about 160 degrees) → automatic vacuum suction → cooling (about 40 degrees) → stripping → trimming → grooving → three-dimensional luminous characters. (Trimming → bonding words and panels → block splicing → plastic light box).

The mold can be made by woodworking jigsaw or computer engraving. The punch must be inclined, and the upper and lower parts can be removed. The heating temperature is suitable, not the higher the temperature, the better. When the temperature is high, the acrylic sheet will crack, lose its own flexibility, and the suction pressure depth will be unsatisfactory. The automatic vacuum forming system and the intelligent temperature control automatic control system are the core components of the acrylic processing equipment, and other heating boxes, frames, etc. are simple. There are two types of cooling: natural cooling and air cooling. The timing of demolding should be mastered well. If it is too early, the text will be deformed, and if it is too late, it will be difficult to demold, and the possibility of mold reuse is small. Trimming is to fix the edge trimmer used by woodworking on the ordinary desktop, and it can be repaired with a straight knife. "Adhesion" is very important in acrylic products, and sealing, firmness and no flow marks are the keys to ensuring the perfect product.

Since the size of the text determines the thickness of the acrylic sheet, generally, the thickness of the characters below 25 cm can be 2mm thick. Due to the different stroke spacing of the characters, the upper part of some characters is not sucked in place. If the stroke depth of the characters is the same, only the processing technology of KFC characters can be used. This process is similar to the metal word processing process. If a picture has multiple colors, it is necessary to make corresponding molds according to different colors. For the later butt fit, the mold should consider the thickness and slope of the acrylic sheet. A picture of multi-color monochrome plates is sucked out and then applied with color stickers of different colors, and heated with a plastic welding gun, and a perfect product can also be obtained. In the production of blister light boxes, the panel and the text can also be formed by suction and pressure at one time, and then the color stickers can be pasted on the surface of the text. But be sure to use 3M and other high-quality light box stickers that do not change color.

The frame of the blister light box is the same as that of the traditional light box, but due to the large thermal expansion coefficient of the acrylic plate, the shrinkage is about nine times that of the metal type, and there should be room for expansion and contraction when installing or fixing.

The main application areas of plastic light boxes

1. Construction: such as shop windows, soundproof doors and walls, lighting covers, solar collectors, telephone booths;

2. Advertising display categories: such as light boxes, signboards, signs, display stands, spherical covers, and road signs;

3. Industrial products: such as instrument panels, machine shields, flow meters;

4. Lighting: such as fluorescent lampshades, lampshades of various shapes for environmental purification equipment;

5. Civilian category: such as bathroom equipment, dressing table, photo frame, item rack, gift, souvenir, chair back, candy box, information rack, food cover;

6. Medical categories: such as baby incubators, test kits, thermostats, operation cabinets;

7. Special-purpose categories: such as windows and windshields for aircraft, yachts and automobiles, periscopes for submarines and trenches, etc.
