Rubber is an ideal substrate for engraving or etching because it is soft and highly absorbent.
However laser marking rubber does not offer contrast.
Tires and handles are a few examples of markings done on rubber.
ZGG laser marking machine is capable of marking on rubber and the ideal system for your application depends on your marking requirements.
The only factors to consider are the speed and depth of the marking, as each laser series offers the same exact marking type.
The more powerful the laser, the faster the engraving or etching process will be.
