Silicone screen printing characters easy to drop reasons?

In the processing of silicone products, screen printing is an important process, because it can achieve character engraving in silicone products, this function is very important for silicone buttons and other products, good screen printing level can improve the quality of characters, but in the process of silicone products screen printing, sometimes the characters out of screen printing will fall out. So what is the cause of silicone products after screen printing characters will fall out?

The character wear resistance of silk-screen silicone products is poor

Form of expression: the characters of silicone products printed by silk screen after several uses, the characters begin to blur

Cause:

1. After the screen printing baking time is short or low temperature, pay attention to: the standard value of baking temperature and time difference is too far, and the temperature is too low

2. The quality of screen printing ink is too poor, pay attention to: the surface of silicone products will also affect

The characters are wiped away after the screen printing

Cause:

1. The surface of silicone products is too dirty, preventing the adsorption of screen printing ink and silicone, causing the character to be wiped away.

2. The time or temperature of baking after screen printing is insufficient, pay attention to: screen printing ink should be fully cured

Solution: Check the set temperature of the baking tunnel furnace and the running speed of the tunnel furnace. Check again whether the tunnel furnace and circulating fan are open

3. Screen printing ink problem

Note: Can not use the wrong ink < silicone screen printing ink >

In SUMMARY:

Screen printing is a very important process, in the operation process to correctly pay attention to whether the surface of the silicone products is clean, pay attention to the baking temperature and time after screen printing, especially in order to save costs with low quality screen printing ink and use others to replace, which will lead to the emergence of adverse conditions, affecting the quality of silicone products. In the end, it's not worth it!
