Vacuum Forming light box three-dimensional luminous character processing technology
1. Eye-catching: Being different is always the goal and driving force of the advertising industry. In today's flood of print advertising, the public needs a new form of advertising that can relax the eyeballs, and Vacuum Forming light boxes came into being. Vacuum Forming light box advertising breaks through the traditional two-dimensional expression method, uses three-dimensional modeling to activate people's spatial imagination, and has a strong sense of three-dimensional modeling.
2. High cost performance: taking into account both daytime and night effects.
3. Green and environmentally friendly: Because acrylic materials can be completely recycled and reused, they are regarded as a green advertising form for the 21st century.
1. Film pasting: For Vacuum Forming light boxes with simple forms, small quantities and low cost accounting, we use the film pasting method. But here we must emphasize not to use those very cheap films that are easy to fade in the market, and must use those brand light films with a long shelf life outdoors, otherwise the maintenance cost will be very high, and such a temporary low cost will result in higher maintenance costs.
2. Screen printing: This is a very common way of processing the screen of Vacuum Forming light boxes, and it is also ideal, especially when we have a certain number of practices, but we must use good ink when silk-screening, because our plates must also be baked and pressed at high temperatures; otherwise, they are easy to scratch during the production process and are easy to fade after a period of use.
3. Another kind is outdoor photo light sheets: Generally, Vacuum Forming light boxes with small quantities and difficult alignment choose this method, but outdoor light sheets must be used.
From multinational companies such as McDonald's, KFC and Pizza Hut to China's chain supermarkets, banks, and Jiefang Commercial Vehicle Service Center shop signs, there is a huge business opportunity for advertising product logos. Acrylic processing is inseparable from molds. The mold can be made of wood, plaster, steel, etc., and the mold selection can be determined according to the size of the processing batch. Wooden molds save costs and are only suitable for small-scale processing, because they will lose water and deform over time, and the finished product will naturally be unsightly, and it will also cause trouble for post-production (need to be processed). The pre-production of Vacuum Forming light boxes and three-dimensional luminous characters is the same: film making ¡ú heating (about 160 degrees) ¡ú automatic vacuum suction ¡ú cooling (about 40 degrees) ¡ú film stripping ¡ú trimming ¡ú slotting ¡ú three-dimensional luminous characters. (Trimming ¡ú bonding characters and panels ¡ú block splicing ¡ú Vacuum Forming light boxes).
Molding can be done by woodworking curved saws or computer engraving, and the convex mold should be inclined, with a small top and a large bottom so that the mold can be removed. The heating temperature should be appropriate, but the higher the temperature, the better. When the temperature is high, the acrylic sheet will crack, lose its own flexibility, and the suction and pressure depth will be unsatisfactory. Automatic vacuum Vacuum Forming system and intelligent temperature control automatic control system are the core components of 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 demoulding should be mastered. If it is too early, the text will be deformed. If it is too late, demoulding will be difficult, and the possibility of mold reuse will be small. Trimming is to fix the trimming machine used for woodworking on an ordinary desktop and trim it with a straight knife. "Bonding" is very important in acrylic products. Sealing, firmness and no flow marks are the key to ensuring the perfection of the product.
Since the size of the text determines the thickness of the acrylic sheet, generally, 2mm thickness is sufficient for characters below 25cm in height, and the thickness of the characters should also be below 2cm. For large characters above 2 meters in height, 5mm thickness is sufficient. Due to the different stroke spacing of the text, the upper half of some characters cannot be sucked in place. If the depth of the text strokes is consistent, only the processing technology of KFC text can be used, first cut out the text surface, then cut out the edge strips of the text, and then glue them. This process is similar to the metal character processing process. If there are multiple colors in one picture, the corresponding molds must be made according to different colors. In order to match the later docking, the mold should consider the thickness and slope of the acrylic sheet. After the single-color sheet with multiple colors in one picture is sucked out, different colors of color stickers are added, and heated with a plastic welding gun, a perfect product can also be obtained. In the production of Vacuum Forming light boxes, the panel and text can also be sucked and pressed into shape at one time, and then the color stickers can be pasted on the surface of the text. But it is necessary to use high-quality non-discoloring light box stickers such as 3M.
The frame of the Vacuum Forming light box is the same as the traditional light box, but because the thermal expansion coefficient of acrylic plate is large, the shrinkage is about nine times that of metal, so it should be considered to leave room for expansion and contraction when installing or fixing.
If you are facing a regional market, you don't need to use a screen printer. Because the quality and processing technology of acrylic determine its high price. From plate making to printing, small batches of screen printing are not cost-effective. If the two are added together, the price is unacceptable to ordinary users. After receiving an order, go to a professional screen printing factory for printing. The quality is good, the price is low, and it saves money. Why not do it?

¨T¨T¨T¨T¨TThere are many netizens on the Internet who are concerned about the price of Vacuum Forming light boxes. The answer is as follows¨T¨T¨T¨T¨T
About the algorithm of the price of Vacuum Forming characters: Many people in the industry have never understood the algorithm of Vacuum Forming characters. Now I will briefly talk about the algorithm. Welcome everyone to discuss: Vacuum Forming characters are usually calculated according to the longest side of the characters. If the longest side of the characters is less than one meter, it is calculated in centimeters; if the longest side is higher than or equal to one meter, it is calculated in squares. It should be noted here that if one side of the character is more than one meter and the other side is only forty or fifty centimeters, then the calculation should be like this: (character length + character width) ¡Â 2 ¡Á unit price; the algorithm of Vacuum Forming light boxes is basically the same, but it needs to be divided into single-sided or double-sided. The above are just some of my algorithms, and people in the industry basically calculate it this way. If there are colleagues who have better algorithms, please suggest them to us, thank you!
¨T¨TTo make exquisite Vacuum Forming light boxes, the color picture processing of Vacuum Forming light boxes is very important, sharing as follows¨T¨T
Many company LOGOs or designed images are not single colors, so Vacuum Forming light boxes have to face many color processing, and there are many ways to treat acrylic surfaces.
¨T¨TMaking Vacuum Forming light boxes, summarize the experience as follows for everyone to share¨T¨T
1. First make the mold. The thickness of the light box piece is only within 3 cm. To make the mold, you only need to grind the lower side of the yin and yang molds to demold. If the thickness of the light box piece is higher than 3 cm, the positive mold must be made into a shape with a small top and a large bottom to facilitate demolding.
2. Material selection. There are many kinds of plastics that can be used to make light boxes, such as ABS, PC, PMMA, and Nott Vacuum Forming light boxes. It is concluded that PMMA is the best material for light boxes. Other plastics such as ABS and PC are relatively cheap, but the effect is not as bright as that made of PMMA materials. Therefore, we recommend that you use PMMA to make light boxes.
3. Profiles. The thickness of aluminum profiles is the key. Generally, the thickness of the profiles should be 1.2mm. The larger the light box, the more angle irons are needed to support it.
4. Lamps
The production of Vacuum Forming light boxes requires mastering 4 key points and going through more than a dozen processes:
The first is material selection. At present, the plates seen in China are basically imported or produced by foreign joint ventures, and the quality of the plates should be said to be better. The high market price of Vacuum Forming light boxes is one of the main factors for the high price of plates. At present, the unit price of the board in the market is generally 20-25 yuan/kg. Not only is the unit price high, but the utilization rate of the whole board in the production process is not high, resulting in a large cost amortization.
The second is mold making. As we all know, the force plate is formed by vacuum positioning and suction and pressure. Even if it is the same word, different sizes require different molds, and the mold making itself requires high precision and high quality. Because the precision and quality of the mold itself are directly related to the quality of the product, and the mold making has a high level of technology and requires experienced technicians. Therefore, as mentioned earlier, the current Vacuum Forming light box in the market has always been at a high price, and the processing of the mold should be said to be the most important technology.
The third is post-production. As mentioned earlier, the current Vacuum Forming production is basically mechanized. The application of some new equipment has greatly reduced the labor intensity of workers while improving production efficiency. After the Vacuum Forming material is basically formed, it must go through several processes such as milling, milling, and grinding. Finally, the light box is laid with light sources and the production is completed after baking.
The fourth is picture processing. According to different needs of customers, the screen printing can be used to directly transfer the picture to the plate, and then it can be formed by vacuum suction and pressure. The picture contains people, animals or product images, and can be vacuum-formed into a three-dimensional effect, thus achieving better publicity effect.
