Abstract

The invention provides an in-mold integral-forming image and text transfer printing method for a silicone button. The method comprises the following steps of 1) back coating of a PET sheet; 2) front coating of the PET; 3) coating on paraffin; 4) color printing of the image and text; 5) printing of environment-friendly glue; 6) adoption of a special punching machine for punching positioning holes;7) silicone oil pressure forming; 8) tearing of the PET sheet after vulcanization is completed so that a pattern can be transfer-printed on a silicone button product, and out-taking of the silicone button product. According to the method, positioning is needed during surface printing on the silicone button, and when silicone is made at first and afterwards printing is conducted, the shrinkage of the silicone is inconsistent, so that the deviation of printing positioning is caused; the mode of printing the pattern on the PET and then conducting mold pressing is adopted, the printing position isvery accurate, and the error can be 0.05 mm.

Description

technical field [0001] The invention relates to the technical field of image-text transfer printing technology, in particular to a method for integrally forming image-text transfer printing in a silicone button mold. Background technique [0002] At present, some technologies are to shape the silicone products first, then print the characters, colors, and patterns with special jig screen printing, and then spray oil and laser engraving. This technology has the following disadvantages: 1. After repeated baking, the size control is not easy to control at high temperature, resulting in many defects. 2. The centering of the surface printing position is not good, and the deviation is large. 3. There are many production processes, resulting in long production cycle and low pass rate. 4. More production personnel are required. The cost is high. 5. The estimated overall cost is 50% higher than the cost of the new process method. Contents of the invention [0003] In view of t...
