Introduction of manufacturing technology of blister light box

With the rapid development of China's economy, urban construction is becoming more and more beautiful, especially after walking in the streets at night, neon lights are flashing everywhere, and even some bustling streets are brightly lit every night. For example, billboards and doorplates of major banks will be on all night, and there are signs such as 24-hour supermarkets and express hotels. These signs adorn the night sky of the city at night, forming a beautiful scenic line. So do you know what this sign is? In fact, this is a blister light box. The following small series will introduce it to everyone!

Manufacturing technology of blister light box

Processing technology of three-dimensional luminous characters in blister light box

From multinational companies McDonald's, KFC and Pizza Hut to domestic supermarket chains, banks and Jiefang commercial vehicle service centers, there are huge business opportunities for advertising product identification. Acrylic processing is inseparable from the mold. The mold can be made of wood, gypsum, steel, etc. And the material selection of the mold can be decided according to the number of processing batches. Wood model saves cost 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 is naturally unsightly, which also brings trouble (need to be treated) to the later production. The pre-production of blister light boxes is the same as that of three-dimensional luminous figures: film making → heating (about 160 degrees) → automatic vacuum suction → cooling (about 40 degrees)? → demoulding → trimming → slotting → three-dimensional luminous characters. (Trimming → Bonding words and panels → Block splicing → Blister light box).

patternmaking

Modeling can be done by woodworking puzzles or computer carving. The hole should be slanted, and the stool can be peeled off. Proper heating temperature does not mean that the higher the temperature, the better. When the temperature is high, the acrylic board will crack and lose its elasticity, and the pressure absorption depth is not ideal. Automatic vacuum suction system and intelligent temperature control automatic control system are the core components of acrylic processing equipment, while other heating boxes and frames are relatively simple. There are two kinds of cooling: natural cooling and air cooling. The timing of demoulding should be well grasped. If it is early, the characters will be deformed. If it is too late, it will be difficult to demould, and the possibility of reusing the mold will be small. Trimming is to fix the trimmer for carpentry on an ordinary desktop and trim it with a straight knife. "Adhesion" is very important in acrylic products, and sealing, firmness and no flow marks are the keys to ensure the perfection of products.

Due to the size of the text, the thickness of the acrylic board is determined. Generally, the word thickness below 25 cm is 2mm, the word thickness below 2cm is 5 mm, and the word thickness above 2 m is 5 mm. Because of the different stroke spacing, the upper part of some words cannot be sucked in place. If the stroke depth of the characters is consistent, we can only use KFC character processing technology to cut out the characters first, then cut out the edges of the characters and stick them together. This process is similar to the metal word addition process. If a painting is multi-colored, you have to make corresponding molds according to different colors. For the later docking, the thickness and inclination of acrylic plate should be considered in the mold. A picture of multi-color and monochrome plates can be sucked out, pasted with different colors and heated with a welding torch, and a perfect product can also be obtained. In the production of plastic light boxes, the panels and characters can also be molded by plastic suction at one time, and then the color paste can be attached to the surface of the characters. But be sure to stick it with a high-quality color-stable light box such as 3M.

summary

The frame of the blister light box is the same as the traditional light box, except that the thermal expansion coefficient of acrylic plate is large, and the shrinkage is about nine times that of metal, so it is necessary to leave room for expansion when installing or fixing.

If you are facing the regional market, you don't have to look for a screen printing machine. Because the quality and processing technology of acrylic determines its high price. Screen printing from plate making to printing, small batch is not cost-effective, if the two together, the price is unacceptable to ordinary users. After receiving the order, you can print it in a professional screen printing factory, which is cheap and saves money. Why not?

Through Bian Xiao's detailed introduction to everyone, I believe everyone has a brand-new understanding of plastic light boxes. The night view of our city depends entirely on the decoration of these plastic light boxes, which makes our living environment so beautiful. Therefore, it is beneficial for everyone to properly understand the manufacturing process of plastic light boxes. Of course, whoever wants to open a shop will have to make a customization in the future. In fact, blister light boxes are widely used, including architecture, advertising display, industrial products, lighting, civil, medical and some special purposes. Of course, this needs further understanding.
