There are three kinds of materials widely used in light box signboard industry: acrylic board, PC board and PVC light box cloth, and acrylic board is undoubtedly the most promising one.
According to the different needs of customers, Goodbon Technology directly transfers pictures to acrylic plates through screen printing, and then carries out vacuum stamping, in which there are people, animals or commodities in the pictures, and can also be sucked and printed again to form a three-dimensional effect, thus obtaining better publicity effect.
Production technology of Goodbon acrylic light box;
(1) Mould making and common moulds are all wooden moulds, which can be sawed once with the formwork produced by our company or made with portable reciprocating data (the price is about 200- 1000 yuan).
(2) mold deep processing: polishing and trimming to make the mold smooth and flat.
(3) Positioning the mold on the plastic suction platform, and overlapping and fixing the alignment positions of the male mold and the female die.
(4) Heating the acrylic board, the upper limit of the temperature of the main machine of the plastic suction equipment is usually set to 70℃, and the lower limit is 150℃.
(5) After the acrylic board is heated to the required temperature for softness, it is placed on the (Type I and Type II) plastic suction platform for sub-molding.
And (6) milling off the redundant corners of the molded semi-finished acrylic board with an edge milling machine.
(7) The acrylic panel for splicing acrylic characters (Note: this process is not required only for acrylic light boxes). Choosing the right metal frame and the metal frame of electric lighting equipment is mainly to integrate all parts of the light box, which needs accurate size, beautiful appearance and certain mechanical strength sealing performance to protect the electric lighting part inside the light box from being damaged. As for the use of specific materials, it needs to be determined according to the actual situation, and both aluminum alloy profiles and steel products can be used.
In order to obtain a good visual effect of acrylic indoor lighting light box, we must carefully consider the related lighting configuration. Due to the colorful colors of acrylic board and various lighting appliances, it seems impossible to formulate a set of simple rules to ensure that every different light box signboard has the best visual impact effect, but for most forms of signboards, the lighting methods to be adopted are foreseeable. Every unique signboard, logo and light box needs to be made in advance to ensure the best lighting effect. Brightness Brightness refers to the brightness of a certain point on the surface when viewed from a fixed angle. Under different optical concepts, brightness is the most important design-related factor of luminous signs.
To sum up, the main reason why the acrylic light box can't work is that there is a problem with the built-in lighting system. See/news/2015-1-16/893.html for the maintenance method.
