Electro-aluminum Hot Stamping Failure Causes and Troubleshooting Techniques

1. Electro-aluminum hot stamping is not strong. There are many causes of hot stamping, and there are differences in disposal methods. To sum up, there are three important

1 When the hot stamping temperature is low or the pressure is light, the hot stamping temperature and pressure can be adjusted from time to time.

2 In the printing process, the proper amount of dry oil added to the ink makes the name of the ink layer dry and blunt, resulting in the crystallization of the ink and the hot stamping of the printed foil. The solution is to first prevent the occurrence of crystallization when printing, and secondly , If the crystal is produced, the light stabilizer can be discarded under the hot stamping foil, under the heating conditions, the printed product is air pressed again, and after the crystal layer is damaged, the hot stamping is performed.

3 Insulation can also be caused by the presence of a waxy salt-removing agent, anti-sticking agent, or non-drying oily material exposed in the ink. The result of the determination is to first apply a layer of receptivity to the printing plate. The strong paper was pressed over again, and the amount of wax and non-dry oil on top of the top layer of Zhu was affixed.

2. The picture of the aluminum foil hot stamping is made by

In the hot stamping process, the failure of inventing the picture and text, causing faint halo, is mainly caused by high stamping temperature and coking aluminum foil. If the hot stamping temperature of the printing plate is too high, the electrochemical foil exceeds the limit that can be accepted. At this time, hot stamping, electro-aluminum foil will expand to everywhere, resulting in dizziness, hair virtual phenomenon, must be based on the characteristics of the electrochemical foil to adjust the temperature to the appropriate scale.

The coking aluminum foil, mainly in the hot stamping process shutdown too long, so that a certain part of the long time of electrification of aluminum foil to warm the cold plate touch and produce a hot coking scene, the image will be dizzy after hot stamping. Therefore, during the production process, if it stops, the temperature should be lowered, or the electro-aluminum foil can be moved away. It is also possible to lift a thick paper in front of the higher-temperature printing plate to isolate the electro-aluminum foil from the plate.

3. Electrochemical aluminum writing is ambiguous.

The main reasons for this failure are the high stamping temperature, the excessive thickness of the electro-aluminum aluminizing layer, the excessive energizing pressure, and the relaxation of the electro-aluminum device. The corresponding measures must be adopted in accordance with the detailed situation. Too high is the main cause of unclear handwriting and stencil printing. During the hot stamping process of embossed aluminum, the emulsifier, if the plate warming power is high, causes the transfer of the film base layer and other film layers, and becomes sticky, making the writing unclear and paste. Edition. Hot stamping should be based on the practical range of temperature of the aluminum foil, suitable for the reduction of hot stamping temperature. In addition, the thickness of the aluminum layer should be selected aluminum, adjust the appropriate pressure, and properly adjust the pressure roller pressure follow-up Roller roller pull.
