1. Requires vulcanized rubber material. The reason why we talk about it separately is because there is a special process in its production process: vulcanization. And because of the particularity of the application scenario, the surface of the material cannot be damaged. This allows us to put aside the laser marking machine directly. The vulcanization process requires the ink to have anti-vulcanization properties. This type of rubber ink Suzhou Sunrise has mature products and has been put into the market for more than five years. In conjunction with the dot matrix The large-character inkjet printer can inkjet code on the surface of unformed rubber tires to achieve the purpose of identifying tire specifications and models.
2. PU material. The inkjet process can hardly adhere to the surface of this type of material. Currently, laser or pad printing and silk screen printing are used for inkjet marking of this type of material.
3. Other soft rubber materials. If there is no special process similar to vulcanization, most soft rubber materials will have slightly poor friction resistance after being marked with an inkjet printer. For manufacturers with low requirements and temporary marking, the inkjet process can still be selected. , especially some soft rubber materials whose surfaces are relatively smooth and flat after special treatment, and even have better firmness.
For manufacturers with low efficiency requirements and good cost acceptance, you can also choose screen printing or pad printing, but when it comes to variable data printing, the practicality will become very low.
Another way to achieve variable data marking is laser marking. As we all know, laser marking relies on burning materials to mark, and soft rubber materials will produce more smoke during the laser marking process and require equipment. For smoke purifiers, after using the laser marking process on the black material surface, you will find that the marking effect is not that obvious. After all, the black glue material still appears black after being burned. However, the higher the laser power, the deeper the burning depth. The marking effect will be improved.
