There are three reasons

A, itself has a problem

     If the silica gel filter time is not good, there are impurities or in the process of packaging, workers in the partial shipments are not wipe off the bucket and tape, rubber pad printing is not durable.

B, related to the proportion of silica gel not adapted

     Because of the adding amount of silicone oil and silicone, silicone oil is added to the more, make glue head is more soft, silicone oil can destroy the molecular weight of silica gel, and rubber head not durable wear-resistant, easy to aging, etc.

C, the manufacturer's reason

     Vendors do not understand the use of the rubber pad printing head, because of the rubber pad printing head using life and has a close relationship between the size of the printing design, if you want to print larger pattern, must use the rubber head pad printing.On the contrary, you should use small plastic head, according to the size of the pattern to adjust the size of the rubber head (suggest general rubber head the size of the design with the size of the ratio of 3:1)
