Description:1. The reason why the pad printing silicone head is not durable? ① There is no problem with the pad printing silicone itself. The problem is that the silica gel is not well filtered, and there are impurities; or during the packaging process, the bucket or plastic bag is not scrubbed clean when manually repacking, which makes the pad printing silica gel head not durable. ② It has a lot to do with the amount of silicone oil added in the pad printing silicone. The more silicone oil is added, the softer the rubber head will be, because the silicone oil will destroy the weight of the silicone, resulting in non-durability and easy aging. ③ Silica gel application manufacturers do not understand the performance of pad printing silica gel. The service life of pad printing silica gel is closely related to the size of the pattern to be printed. Many factory supervisors are afraid of trouble,

Answer:

1 . The reason why the pad printing silicone head is not durable?

①   There is no problem with the pad printing silicone itself. The problem is that the silica gel is not well filtered, and there are impurities; or during the packaging process, the bucket or plastic bag is not scrubbed clean when it is manually divided, which makes the pad printing silica gel head not durable.

②It has a lot to do with the amount of silicone oil added in the pad printing silicone. The more silicone oil is added, the softer the rubber head will be, because the silicone oil will destroy the weight of the silicone, resulting in non-durability and easy aging. 

③Silica gel application manufacturers do not understand the performance of pad printing silica gel  . The service life of pad printing silica gel is closely related to the size of the pattern to be printed.  Many factory supervisors are afraid of trouble and are unwilling to replace the pad printing head according to the size of the pattern. If you are printing a large pattern, you must use a larger rubber head, if the pattern is small, you can use a small rubber head (adjust the size of the pad printing head according to the size of the pattern, the ratio of the size of the rubber head to the pattern is 3 : 1 )

 

2.  Why is the pattern unclear and incomplete during the printing process of the pad printing silicone head?

①When the pad printing rubber head is too hard, the printing pattern will be incomplete, because the pattern pattern is small and small, and the rubber head is too hard. The pad printing head itself does not absorb the pattern ink on the stencil on the glue head, so the pattern printing will not be complete. If your pattern is small and fine, you must use a soft glue head to print, so that the problem can be solved. . 

②If the water content in the ink is too high, the printed pattern will also be incomplete, and there will be spots. It is recommended to clean the oil cup and replace it with new ink or Tianna water. 

③How is the moisture in the ink formed? Generally, the moisture in the ink has a great relationship with the humidity of the air, because the weather temperature is high, especially in rainy days, and some pad printing workshops have to clean the floor or mop the floor after get off work in the morning and evening. The steel of the pad printing machine produces small water droplets, which turn into large water droplets and flow into the ink. 

 

3. Why is the pad printing silicone not oiled? 

Any pad printing head or glue is oiled. If the customer prints a large pattern and the characters are thick, it must be oiled. If the English letters are not oiled, the reason is that the hardness of the glue head itself is too high, and there is no oiling. The ink under the steel plate is adsorbed on the rubber head, so I thought it was not oiled.

 

4.  Why does the pad printing silicone head not drop oil?

For plastic toys or products that have not been sprayed with paint, two out of ten products have incomplete patterns during pad printing, that is, they do not drop oil, which is a normal phenomenon. Because the injection molding machine is in the process of producing toys, it will spray the release agent on the surface of the steel mold every time it produces more than a dozen products, and there is a lot of release agent on the surface of the first product or the second product of the mold that has just been sprayed with the release agent. , If this product has not been washed with Tianna water or facial water, and it is directly used for pad printing, this phenomenon will occur.
