Making method of case having pattern

Abstract

The invention discloses a making method of a case having a pattern. The making method comprises the following steps: coating PC lightening oil on a PC film, printing the pattern onto the PC film, carrying out primary heating, compounding the PC film to an ABS sheet, carrying out secondary heating, carrying out plastic uptake, and molding to form the case having the pattern. The method is simple, and the making cost of the case is low.

Description

technical field [0001] The invention relates to a process for preparing bags, in particular to a method for preparing bags with patterns. Background technique [0002] As we all know, for the preparation of a travel bag with ABS plastic as the surface material, if you want to print patterns or patterns on the surface of this ABS plastic shell, it is currently completed by the traditional mold opening (printing film) process. The specific steps are as follows: [0003] 1. Organize all the colors in the picture and pick them out separately [0004] 2. Select the steel mold, and each steel mold must not have the slightest scratch, otherwise the finished plate will not be usable. [0005] 3. Computer engrave the patterns of different colors in the picture onto the steel mold respectively. [0006] As can be seen from the above process flow, this mold opening process has the following main defects: [0007] 1. The cost of mold opening is high. For example, a pattern printed wi...

Problems solved by technology

[0004] 2. Select the rigid mold, and each steel mold must not have the slightest scratch, otherwise the finished plate will not be usable

[0007] 1. The cost of mold opening is high. For example, a pattern printed with ten colors needs to open ten molds, and the cost is about 9,500 yuan. For the preparation of small batches, if it is evenly distributed to the cost of each suitcase, the cost is high

[0008] 2. The waste of leftover materials is caused. During the whole mold opening process, the steel mold will cut more leftover materials, and these leftover materials have no other use, so it is very wasteful

[0009] 3. The mold opening time period is long. The mold opening process for a pattern is generally not less than one month. This will cause a time delay for the production of the entire suitcase and even mass production, which is not conducive to the rapid promotion of products

[0010] 4. The entire mold opening process affects the environment. The existing mold opening process needs to be washed with water continuously during the realization process, which not only wastes resources, but also has a great impact on the surrounding environment of the factory.

[0011] 5. Due to the high cost of the mold opening process, it is generally suitable for mass production of travel bags with the same pattern. For consumers who are pursuing individuality, it is impossible to prepare small batches or even individual travel bags with personalized patterns. otherwise the cost is high

[0012] 6. Skilled workers with many years of rich experience are needed, and more personnel are required. Once the color is complicated, the version cannot be modified, and the long-term operation of the operator in the printing room will have a great impact on its health.
