What Is a Laser Cleaning Machine?
A laser cleaning machine is an advanced non-contact device that uses high-energy laser beams to remove contaminants, rust, paint, oxides, or coatings from the surface of materials. It's increasingly becoming the go-to solution across automotive, aerospace, electronics, construction, and manufacturing sectors due to its precision, eco-friendliness, and cost-efficiency.
Unlike traditional methods such as sandblasting or chemical cleaning, laser technology offers a dry, residue-free, and highly targeted process that doesn’t damage the substrate. This makes it ideal for sensitive or high-value surfaces.
