Stamp laser punching has high precision, high speed, high efficiency, strong universality, high comprehensive economic benefits and other advantages. Compare to traditional stamp punching, it has better quality and last much longer.
As one of the key technology in the field of modern manufacturing, laser punching technology has strength in decreasing material deformation, improving processing precision and flexibility etc.
But we definitely think the laser punching technology has the advantage in technology application of stamp industry under the current circumstances. It’s magical to see!
