Controlled Coating and Paint Removal with Minimal Surface Impact

Laser cleaning enables efficient removal of old coatings and paints with a low level of surface interference, making it a superior solution for delicate or high-value components. For sensitive materials, Grawostar recommends using MFMDC laser heads (CL series), which are specifically designed for non-invasive cleaning at high precision.

In contrast, coarse cleaning tasks—such as treating bridge structures, automotive underbodies, or heavily corroded metalwork—can be carried out with CW4-designated devices, optimized for durability and power.

Choosing the Right Laser for the Job

While laser cleaning is known for its non-contact, fast, and safe cleaning process, it’s essential to match the laser type to the task. For example, CW (continuous wave) lasers, commonly used for welding, generate significant heat, which may affect thermally sensitive parts.

That’s why final or precision cleaning is always performed using the Grawostar CL200 laser. This system emits ultra-short, high-peak-power pulses that vaporize thin surface layers without heating or distorting the base material.

Benefits of the Grawostar CL200 System

• No risk of thermal deformation

• Perfect for molds, valves, and precision tools

• Ideal for industrial production environments

Clean Workspaces and Unique Material Compatibility

One of the most significant advantages of laser cleaning is the cleanliness of the work environment. Unlike abrasive blasting, laser technology produces minimal dust and no secondary waste. It can also be used to clean components that cannot be sandblasted, such as bearings, valves, and complex machine parts.

However, due to the high kinetic energy of expelled particles, a dedicated fume and particle extraction system must always be in place to ensure operator safety and workplace cleanliness.
