Laser Cleaning

Today, laser cleaning is a general term that includes many other methodologies and technologies. The basic principle of the process is the complete or partial removal of layers from a base surface, material, or substrate, at thicknesses from 1 to 1000 μm, and at a high speeds measured in cm²/s. In defined conditions is possible to remove metal, plastic/polymer, and glass/silicate layers, or even organic materials.

Laser cleaning is always a combination of three basic processes – vaporisation, sublimation, and disruption of adhesion, i.e. the bonds between the removed and base material. The base material is minimally affected thanks to the laser beam’s short and very powerful pulses that contain very little heat input. In certain cases the laser process is inert to the base material, and thus does not cause any changes to its surface or internal structure.

SPYRE Technology

HEAVY-DUTY, BUILT FOR INDUSTRY

Having a robust mechanical construction enables long-term work in more demanding conditions than is standard for other laser cleaning configurations. We adapt the technology to the required application, and we implement the required means for the stability of the serial process.

ACTIVE COOLING AND HEATING OF MAIN COMPONENTS 24/7

To ensure sustainability, we work with components that we can control in various working conditions – actively adjusting the required temperature and flow of the cooling medium. This serves to prevent problems that might otherwise frequently occur due to overheating or low temperatures during the process.

GREEN TECHNOLOGY

SPYRE laser technology is designed so that no future need arises for the disposal of hazardous materials originating from the laser cleaning process, and no additional costs or energy requirements arise during the laser process or waste management.

LASER PROCESS QUALITY

Thanks to the use of high-quality optical components, SPYRE technology allows us to use maximum possible laser power, thereby increasing process efficiency and speed.

LASER SAFETY

We make sure our machines comply with European standards. For each laser cleaning application, we individually analyse safety risks associated with both direct operation and protective cover.

MEDICAL AND FOOD INDUSTRY USAGE

SPYRE laser systems can even be implemented in environments demanding extreme cleanliness and process stability, e.g. processes in the medical and food industries, which demand high quality and surface cleanliness.

Terminology

The basic principle of laser decoating is the partial removal of thin vapour-deposited, sputtered, or varnished layers, with thickness measure in units of μm, to preserve the visual and functional properties of the base material. This process does away with masking individual parts and so eliminates maintaining jigs and simple changes to the pattern that is removed from the base material. Because of the frequent use of the process on visible or exposed surfaces, the process must meet high requirements for accuracy and homogeneity of the result.

A commonly used base material is polymer, from which metal layers – such as aluminium, iron, chromium, or other layers with a polymer or metal base – are removed. We use 10–100 W lasers with a very short and powerful pulse that has minimal impact on the base material, which guarantees a wide possibility of layer thicknesses and types of basic materials.
