What is Laser Cleaning?
Laser cleaning is an innovative technique that uses a fiber laser to remove rust, oxide, and paint from metallic surfaces without altering the properties of the material. Laser cleaning does not require any chemicals or consumables and can be used to prepare surfaces for subsequent production steps.
Laser cleaning is a non-contact and non-abrasive process. The fiber laser removes contaminants, impurities, and deposits from the surface, without chemical treatments (using acids or solvents) and mechanical methods (sandblasting and buffing), while leaving the underlying material untouched.
Laser cleaning is a cost-effective and automated process that does not require the purchase of consumables and the disposal of rinse water. Inline laser cleaning solutions reduce human intervention and, therefore, the need for manpower. Thus, the return on investment of laser cleaning systems is one of the most important throughout the manufacturing industry.
Compared to traditional cleaning methods, laser cleaning does not use dangerous products for the environment and its users, such as acids, solvents, or chemicals, reducing risks related to contamination, environmental pollution, and exposure to hazardous materials. In addition to being eco-friendly, laser cleaning is safe for employees.
When metals are exposed to humidity and oxygen, they react with water to form ferrous oxides, resulting in rust. Rust degrades the quality of the metal and must be removed before proceeding to surface treatments, such as anodization and chroming. Laser rust removal offers numerous benefits compared to traditional chemical and mechanical methods.Learn more
When aluminum is exposed to humidity and oxygen, a chemical reaction called redox (for reduction-oxidation) occurs and creates oxide, which reduces deterioration of the aluminum by reducing its exposition to oxygen. Oxide layers must be removed because welding and surface preparation require oxide-free surfaces. Laser oxide removal offers many benefits compared to traditional methods.Learn more
Some metal and aluminum surfaces must not be covered with paint to not interfere with the assembly, create imbalance, or generate friction. Paint must also be removed prior to welding or surface transformation. Laser technology to remove paint from manufactured parts is a time and cost-effective alternative to masking.Learn more
Laser Mold Cleaning
Molds, tools, and pieces of equipment are submitted to industrial working conditions. Maintenance is key to protect them from wear and tear. Laser cleaning is the optimal solution for cleaning molds used for rubber, plastic, glass and composite products, as well as for industrial tools and equipment.Coming Soon...
Laser Surface Texturing
Laser surface texturing helps to remove protective coatings and anodization from aluminum in preparation for adhesive bonding. Laser texturing is key to prepare surfaces before they are glued, resulting in excellent bond strength quality for improved resistance and durability.Coming Soon...
Laser Surface Preparation
Laser weld preparation helps to remove ferrous and nonferrous metals, lubricants, and other contaminants from metal and aluminum surfaces in preparation for high-quality welds. This surface pretreatment ensures smooth and pore-free brazed seams.Coming Soon...
Laser Cleaning Equipment
Laserax develops, produces, and commercializes a selection of industrial laser equipment for cleaning applications. With high repetition rates, short pulses, and power levels up to 500W, the Laserax laser cleaning systems are the solution for industries looking for a fast, flexible, and robust industrial cleaning equipment.
Automotive parts that are assembled in critical points must be clean and coating-free to move on to the next steps of the manufacturing process, such as painting, welding, and bonding. Paint particles, for instance, must be removed so that they do not interfere with the assembly, create imbalance, or generate friction. In addition, tools and molds must be cleaned regularly, especially if they are used in a harsh environment. Laser cleaning is commonly used to remove contaminant layers such as rust, paint, and oxides as well as to prepare and texture surfaces before further treatments, such as adhesive bonding and anodization.
The aerospace industry is subject to very high safety standards. During maintenance, the aircraft must be dismantled and dust must be removed from critical parts to guarantee the aircraft’s integrity and long-term reliability. Laser cleaning does all this without attacking, modifying, or impacting the surface of aircraft parts.
Power generation stations must be refurbished regularly over their lifetime to guarantee their integrity, prevent environmental catastrophes, and ensure public safety. This maintenance consists in cleaning all the power plants, and more particularly the critical parts, for safety. Laser cleaning removes all the debris and impurities without making contact with the material’s surface.
FOOD AND BEVERAGE
Tank trucks and barrels, made of stainless steel, that carry foods and beverages are governed by strict standards of cleanliness. All welds must be cleaned regularly to meet these standards. Acid is usually used to clean the welds that must be thoroughly rinsed with water, which must then be recovered in order to preserve the environment. In contrast, laser cleaning does not use any chemicals while cleaning tank trucks and barrels.
