Presentation of the equipment's characteristics

GST-HP-300W is a professional handheld pulsed laser cleaning system that delivers controlled, low-thermal-impact cleaning for delicate and complex surfaces. The pulsed output provides high peak power with minimal heat penetration, making it suitable for precision tasks on aerospace components, rail transit parts, automotive assemblies, marine vessel maintenance, electronics micro-processing, food-grade equipment, and mold/tool cleaning.

This unit removes a wide range of contaminants — rust, old paint and coatings, oil and grease, oxide layers, and weld-post blacking — without abrasive media or chemical solvents. Its portability and focused beam allow operators to clean confined geometries and intricate structures that are difficult or impossible with conventional mechanical methods. By reducing substrate damage and secondary waste, GST-HP-300W helps lower maintenance downtime and environmental disposal costs while improving inspection readiness and part life.

Professional custom laser source

Engineered specifically for cleaning applications, the unit uses a custom high-performance laser with superior beam quality and a broad, adjustable pulse-width range. This ensures fast, efficient cleaning while keeping heat transfer and substrate damage to an absolute minimum.

Advanced beam-control technology

Precision optical path control prevents edge over-burn and uneven treatment, delivering consistent surface quality across the entire cleaning area and improving overall processing results.

Multiple safety protections

Integrated safety features protect both operators and equipment, including startup interlocks that prevent power-up when the laser trigger is in a firing state, external emergency-stop interlocks, and configurable delayed emission controls to avoid accidental firing.

Intelligent anti-shake system

Built-in anti-shake algorithms stabilize the beam during handheld operation, producing uniform, repeatable cleaning performance comparable to automated systems — even in the hands of a mobile operator.

Ten-plus years of process expertise

Backed by over a decade of industry experience, the product leverages a comprehensive process database that covers full-scenario applications, providing mature, reliable cleaning recipes for complex use cases.

Robust reliability & industrial durability

Rugged mechanical design and stable performance ensure long-term operation in demanding industrial environments, enabling continuous factory use with minimal downtime.
