Blister light box production process introduction
Blister light box production process introduction
From multinational companies such as McDonald's, KFC, Pizza Hut, to domestic supermarket chains, banks, and Jiefang Commercial Vehicle Service Centers, advertising signs contain huge business opportunities. Acrylic processing can not be separated from the mold. The mold can be made of wood, plaster, steel, etc., and the choice of mold material can be determined according to the processing batch. The wood mold saves costs and is only suitable for small-scale processing, because it will lose water and deform after a long time, the finished product will naturally be ugly, and it will bring trouble to post-production (need to be processed).Blister light boxIt is the same as the pre-production of three-dimensional luminous characters: film making → heating (about 160 degrees) → automatic vacuum suction → cooling (about 40 degrees) → demoulding → trimming → slotting → three-dimensional luminous characters. (trimming → gluing text and panel → block splicing → blister light box).
Molding
Mold can be made with woodworking puzzle or computer carving. The punch is 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 plate will crack, lose its flexibility, and the depth of suction pressure is not satisfactory. Automatic vacuum forming system and intelligent temperature control automatic control system are the core components of acrylic processing equipment, and other heating boxes and frames are simple. There are two cooling methods: natural cooling and air cooling. Demoulding time to master. Premature, text deformation, too late, difficult demoulding, the possibility of repeated use of the mold is small. The trimming is to fix the trimming device used by woodworking on the ordinary desktop and repair it with a tool knife. "Adhesion" is very important in acrylic products, and sealing, firmness and no flow marks are the keys to ensure the product.
As the size of the text determines the thickness of the acrylic plate, the thickness of the text below 25cm can be thickened by 2mm. Due to the different stroke spacing of the word, the upper part of some words is not in place. If the stroke depth of the characters is the same, only the processing technique of KFC characters can be used. This process is similar to the metal word processing process. If a picture has a variety of colors, you need to make the corresponding mold according to different colors. For the later docking, the thickness and slope of the acrylic plate should be considered. Suction out a picture of a multi-color monochrome plate, then paste colored stickers of different colors, and heat it with a plastic welding gun to get the product. InBlister light boxIn the production of, the panel and text can also be molded at one time by suction and pressure, and then pasted with color stickers on the surface of the text. But be sure to use 3M and other non-discolored light box stickers.
Blister light boxThe frame is the same as the traditional light box, but due to the large thermal expansion coefficient of the acrylic plate, the shrinkage rate is about nine times that of the metal type, there should be room for expansion or shrinkage when installed or fixed.
If you are facing a regional market, a screen printing machine is not necessary. Because the quality and processing technology of acrylic determines its high price. Screen printing from plate making to printing, small quantities are not cost-effective, if the two add up, the price is unacceptable to ordinary users. After receiving the order, go to a professional screen printing factory for printing, with good quality, low price and cost saving. Why not do it.
