Handheld Laser Cleaning Machine: thorough, chemical-free & efficient cleaning

Laser cleaning systems from novoflow GmbH enable the precise, gentle removal of rust, paint, and other contaminants without structurally altering the underlying surface. Pulsed beam sources that precisely focus the laser on the area to be cleaned allow metals, plastics, glass, ceramics, stone, wood, and rubber to be processed just as safely as delicate aluminum alloys or other coated or painted materials. The technology is energy-efficient, completely eliminates the use of abrasive media, and significantly reduces maintenance requirements, providing you with a sustainable, cost-effective cleaning solution that can be quickly integrated into existing production lines.

Functional principle of pulse laser cleaning

Pulse laser cleaning uses short nanosecond pulses to locally vaporize contamination without damaging the base material. Precise focusing optics and an adaptive control module ensure reproducible results on a wide variety of materials.

·   Non-contact process prevents tool wear and eliminates chemical residues.

·   Selective heat application protects sensitive materials from warping or damage.

·   High surface performance allows throughputs of up to 15 m²/h, which shortens cycle times in automated lines.

·   Simple parameter selection via stored material profiles shortens the setup phase.

The laser beam is guided over an ergonomic cleaning head that weighs less than 1.5 kg, allowing for longer shifts. Further details can be found on our laser cleaning product pages, which provide a concise overview of all technical specifications.

Application scenarios - from the tool core to the monument façade

With just a few parameter settings, the laser cleaning systems adapt to the component geometry, alloy, and type of contamination, allowing tool cores, historic cast iron ornaments, and structured aluminum profiles to be cleaned without contact. They thus replace sandblasting cabinets, wire brushes, and chemical etching baths in a wide range of industries, measurably reducing process costs, setup times, and environmental impact in both automated and mobile applications.

·   Tool molds in injection molding: The finest burrs and polymer residues are removed without damaging polishing structures.

·   Weld seam preparation in shipbuilding: Oxide layers can be removed over large areas, improving the subsequent weld quality.

·   Corrosion protection in historic preservation: Historic metal ornaments are cleaned residue-free and activated for new coatings.

·   Paint removal from aluminum bodies: Thin layers are selectively removed, leaving the base surface unchanged.

·   Pretreatment of copper heatsink plates: Oxide is reduced, and thermal conductivity is permanently improved.

This process reduces consumable costs by up to 70% and significantly reduces downtime. Our application videos show practical examples and visualize the return on investment.

Lasers instead of rays - four strong arguments for clean processes

Conventional sand, dry ice, or chemical processes generate significant consumables and their disposal costs. A laser cleaning system replaces these methods with a single, digitally controlled process step.

·   Consumable-free: Since neither blasting media nor chemicals are added, storage, regular refills, and special disposal are eliminated; this reduces both direct consumption and indirect environmental costs.

·   Precise energy application: The laser focuses the energy exclusively on the scan width, keeping the heat-affected zone to a minimum and effectively preventing microcracks in the base material.

·   Clean working environment: Without dust swirls or volatile solvents, the working air remains clean, the noise level low, and an optional extraction system feeds particles directly into a filter unit.

·   Versatile application possibilities: Whether oxide layers, rust, oil, paint, or coatings – the system reliably cleans a wide variety of materials such as stainless steel, aluminum, or black steel.

This sustainably reduces operating costs while significantly improving occupational safety and environmental protection. A laser safety cabin also provides a controlled workspace for laser welding and laser cleaning processes – safe, practical, and available from us as a complete solution. In addition to our cleaning systems, we also offer laser welding machines.

Ease of use and protection – from touchscreen to interlock

Each laser cleaning device is controlled via a multilingual seven-inch touchscreen display with an intuitively structured interface. The multi-point locking and emergency stop function couple buttons, key switches, and door sensors in a safety chain, immediately deactivating the laser beam as soon as a protective cover is opened or unauthorized entry into the work area is detected.

Laser Safety Officer training is mandatory for the safe handling of handheld lasers. Therefore, we connect our customers with the Luminus Institute for laser safety officer training. This course is aimed at professionals in industry and commerce who work with handheld lasers or in materials processing.

FAQ: Laser cleaning machine

In our FAQ page, we answer the most frequently asked questions about laser cleaning and laser cleaning devices. One of the questions we get asked most frequently? We'll answer it right here!

What is the difference between single pulse laser cleaner and multi pulse laser cleaner?

The difference between single-pulse laser cleaners and multi-pulse laser cleaners lies in their application and the specific cleaning requirements they can meet. These two technologies are recommended in different situations, depending on the materials that need to be cleaned, as well as the type and extent of contamination.

Single-pulse laser cleaners: Precision for sensitive materials

Single-pulse laser cleaners are characterized by their precision and their ability to gently clean sensitive materials. They are often used where it is important to remove contaminants or coatings without damaging the underlying material. A typical example is the cleaning of works of art or historical artifacts, where the surface is delicate and requires particularly gentle cleaning. Single-pulse lasers are also used in the electronics industry for cleaning components and optics, where precision and material protection are crucial. In medicine, single-pulse lasers are used in eye surgery to treat tissue with great precision, for example, in LASIK surgery to correct vision defects.

Multi-pulse laser cleaners: Efficiency for heavy soiling

In contrast, multi-pulse laser cleaners are primarily used in industrial environments where fast and thorough cleaning of heavily soiled surfaces is required. These lasers can remove a wide variety of stubborn contaminants, including rust, paint, coatings, and deposits. Typical applications include the automotive industry, shipping, construction, and the maintenance of machinery and equipment. Multi-pulse lasers are also used in the restoration of monuments and buildings to effectively clean and restore heavily soiled surfaces.

Conclusion: Choosing the Right Technology

Overall, both single-pulse and multi-pulse laser cleaners offer versatile solutions for different cleaning needs. The difference between single pulse laser cleaner and multi pulse laser cleaner depends on the specific applications, the materials to be cleaned and the desired cleaning efficiency.
