Laser Etching
Laser etching is a broad term that encompasses a variety of engravings and shallow engravings.It can be applied to a wide range of products and materials, including automotive parts, medical devices, wine barrels, microelectronic components, and tombstones.In general, laser etching is distinguished from marking in that it changes the surface roughness of a part, rather than simply changing the surface color or texture.The primary use of laser etching is to create fine patterns, designs, text, images, etc. on a variety of materials, and the technology is widely used in many industries due to its precision, speed, and versatility.
