The principle of crystal interior engraving

The principle of crystal interior engraving is a technology that uses a laser interior engraving machine to drive a certain wavelength of laser into the glass or crystal interior, so that a specific part of the interior has a slight crack to form a bubble, so as to "carve" a flat (2D) or three-dimensional (3D) pattern in the crystal and glass interior.
Product innovation is inseparable from advanced processing technology, laser engraving can carve any pattern and graphics, processing technology, low cost, molding speed, fine, the outer surface does not break.
