Pad printing silica gel is a widely used printing material in modern times. Its principle of use is to solidify the pad printing silica gel into a glue head. The glue head will first transfer the graphic ink on the pad printing plate to the desired pad printing. The surface of the product can achieve the effect of fast pad printing. According to different material products, structural shapes, the pad printing paste used, the hardness of the rubber head, and the size of the rubber head are all related.

When using the pad printing silicone head, it is inevitable that some problems will lead to the poor effect of oiling and oiling. The editor of [Shenzhen Hongtu Silicone] summarizes common problems and solutions for you;

1. The pad printing silicone head is oily: When making the rubber head, confirm the initial hardness of the silicone paste first, and then appropriately add silicone oil to dilute it to reduce the hardness of the rubber head. If you need to add silicone oil, it is recommended to consult the silicone manufacturer first; the rubber head can be wiped with soapy water and then wiped with alcohol. If the plastic head that has just been operated is recommended to stand for 24 hours before demoulding for use, the effect is better;

2. Cracks of the pad printing silicone head: First rule out whether it is artificially damaged. For example, the glue head is cracked during the normal pad printing process, first check whether there are sharp objects in contact with the product, or whether the glue head has been used for too long and has aged. If the new glue head is cracked, It may also be that the amount of mixed silicone oil is too large, and the tear strength of the silicone is reduced, and the second is that the pad printing paste is not pure enough (mixed with powder and filler). Although the procurement cost is low, the unstable quality will bring a lot of unnecessary cost. It is recommended to find professional silicone manufacturers to cooperate.

 3. Maintenance of pad printing silicone head: Because of pad printing products of different specifications and shapes, the size and softness of the glue heads used are different in all aspects. Store in a dry and cool place to avoid accelerated aging of silica gel. If the glue head in use is unevenly oiled, it can also be wiped with alcohol.
