To solve the plastic hot stamping silver easy to fall off the factors to consider

Sometimes plastic hot stamping products after a period of time (two or three months) easy to fall off, not all is the problem of the process, when it comes to such a problem, we need to consider more from the following aspects:

1. The hot stamping machine must choose the appropriate hot stamping foil according to the different varieties of the hot things. When hot stamping must grasp the temperature, pressure, hot stamping speed of tripartite coordination, and according to the stamping materials, varies from one of the hot stamping area, hot stamping area is too large, need to be beautiful, hot also need to pay attention to bronzing edition hard silica gel hardness, it is advisable to 90 degrees of silica gel, the stand or fall of this also and electrochemical aluminum bronzing paper and mold layer elastic relationship is very large.

2. In addition, there is too much dry oil in the printing ink. If it is a spot color bronzing, it is best to hollow out.

3, anodized hot stamping foil should choose suitable properties of paper, ink (especially black ink), kerosene, composite glue, hot stamping parts must be kept dry, so as not to cause oxidation or damage to the bronzing layer.

4. General packaging: 64cm×120m in a roll, 10 rolls in a box; Width 64cm, length 120m or 360m large roll or other special specifications.

5, in addition to the material, the temperature will also affect the hot stamping stamping off phenomenon, in addition, the machine abnormality can not be ignored.

6. Sometimes, if you change the gold foil, there will be incomplete hot stamping or whitening phenomenon. This is related to the production batch of hot stamping paper, and the interval between the stop and the hot stamping belt. In fact, we should pay attention to the glue under the gold foil, before changing, we can find the supplier to tell him our needs, and then purchase the test, the same piece of paper, the same temperature, the effect of different manufacturers of bronzing paper are different, the test is as follows:

A. First of all, confirm the quality of electrochemical aluminum foil, whether the quality is worse than that used before;

B. If there is no problem with the quality of anodized aluminum foil, it may be that the performance of anodized aluminum foil and ink does not match;

C. The ink may be wet or sprayed with excessive desiccant. Debugging the matching degree of bronzing is a more challenging and careful work to pay more attention to details to make a good product.
