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 plates should be said to be relatively good. The reason for the high market price of blister light boxes is the high price of plates. At present, the unit price of plate in the market is generally 20-25 yuan/kg, which is not only high in price, but also low in the utilization rate of the whole plate in the production process, resulting in great cost amortization.
The second is mold making. As we all know, the force plate is formed by vacuum positioning and suction pressure, even if it is the same word and different sizes, different molds are needed, and the mold production itself requires high precision and good quality. Because the precision and quality of the mold itself are directly related to the quality of products, and the technological level of mold production is very high, experienced technicians are needed. Therefore, as mentioned above, the blister light box on the market is already at a high price, and mold processing should be said to be the most important technology.
The third is post-production. As mentioned above, the plastic absorption production has basically realized mechanization, and the application of some new equipment has greatly reduced the labor intensity of workers while improving production efficiency. After the blister material is basically formed, it has to go through several processes, such as edge milling machine, planing machine and polishing. Finally, the light box is paved with a light source and baked.
The fourth is image processing. According to the different needs of customers, directly through screen printing; The picture is transferred to the plate, and then shaped by vacuum suction. There are people, animals or goods in the picture, so you can suck it again to form a three-dimensional effect, so as to get better publicity effect.
