Colorful laser processing equipment is an advanced precision machining technology based on laser microstructuring or interference effects. By utilizing high-energy pulsed lasers to create nano-scale microstructures or selective oxide layers on material surfaces, it achieves dynamic color changes, gradient rainbow effects, or metallic luster through light interference, diffraction, or reflection. Its core advantages include non-contact processing, micron-level precision, and eco-friendliness, making it widely applicable in consumer electronics, automotive interiors, luxury packaging, and jewelry design.
