Laser cleaning as an alternative to sand cleaning

Until now, the most popular method for cleaning surfaces was sandblasting. However, it cannot be used in all cases, as it is not suitable for sensitive surfaces with small components that could be damaged during the cleaning process.

Laser cleaning has become an appropriate alternative to sandblasting. A laser delivers a high, concentrated energy pulse that precisely removes old paint, rust, grease spots, and other contaminants without expelling abrasive material.

Additionally, the CL4 Flat variant also allows for polishing surfaces and altering their adhesion properties.

Sandblasting did not allow for cleaning threads. Furthermore, a laser can pass through glass, enabling the cleaning of elements inside a sealed glass enclosure.

Note! The “cleaning through glass” process can only be performed by a highly skilled operator. An example of an item cleaned “through glass” is a watch or a water meter. To clean a clock face, the watch does not need to be opened. This task must be carried out only by trained and experienced individuals using special lasers, as using improper devices may cause coating rupture and injury.

Types of Cleaning Lasers

The advantage of laser cleaning is its versatility. Lasers remove grease, rust, paint, varnish coatings, dirt, and discoloration. More advanced models – such as the Grawostar Laseman CL300 have three variants of the light beam – Gauss, Flat, and Mix beam.

Flat beams are used to clean injection molds and sometimes to polish them. Unfortunately, such specialized equipment does not work where we have to clean the surface to a form similar to that after the glass blasting process.

Gauss beams, on the other hand, can damage chrome metal surfaces, but perfectly prepare surfaces for subsequent chemical and polishing treatment.

Specialized Mix lasers allow for the treatment of stone and wooden surfaces. Unfortunately, wood processing requires the high-speed construction of mirrors that reflect light.

Various phenomena controlled in the production process of the device mean that three different devices are needed to properly clean many types of surfaces.

Laser cleaning is gaining an increasingly wide range of applications, Grawostar lasers are used in production plants, factories, workshops, and wherever we want the most non-invasive surface treatment possible.

The concentrated laser beam is absorbed by the impurities that are on the surface of a given element. The impurity particles pass from solid to gaseous state in a direct way. The material subjected to this process remains almost intact. The degree of violation is determined, among other things, by the type of source (Flat, Mix, Gauss).

Advantages of Grawostar laser cleaning

Many different devices, methods, and technologies are used to clean surfaces, so what are the advantages of laser cleaning? Here are some of the advantages:

speed
low price
no abrasive
no deformation of sharp edges
does not damage threads
can reach the inside of pipes
degreases, preserves
does not destroy bearings
removes bitumen masses from the chassis
multifunctional devices weld and clean at the same time
multifunctional devices can also cut
the system draws very little power
no aggressive noise during the operation

One of the most popular cleaning methods is sandblasting, which due to its relatively high invasiveness and labor intensity cannot be used everywhere. Sandblasting using large machines is noisy and destroys small elements (sandblasting destroys threads, and cannot reach closed holes and gaps). The laser has no problems with this.
