Custom High-Energy Solid-State Pulse Laser Cleaning Machine
Presentation of the equipment's characteristics
The Greenstone GST-SP Series High-Energy Solid-State Pulse Laser Cleaning Machine is an industrial-grade, non-contact solution designed for fast and consistent surface preparation and contamination removal. Built by Chengdu Greenstone Laser Technology Co., Ltd., this system uses a high-energy solid-state pulse laser source with stable energy density and precise control to remove rust, oil, oxide layers, paint/coatings, and stubborn residues without chemical solvents or abrasive media.
To meet real production needs—especially in automotive, shipbuilding, rail transit, machining workshops, and mold maintenance—the GST-SP Series adopts a modular unit design and a self-developed control system that supports flexible cleaning strategies (including 1D/2D/3D control options). The system can be configured for remote monitoring and diagnostics to improve uptime, reduce unplanned downtime, and simplify maintenance planning. With a handheld portable cleaning head, an intuitive touchscreen control panel, and a robust water-cooling chiller, the GST-SP Series delivers repeatable cleaning quality for both large-area jobs and detailed cleaning tasks.
Typical applications include: welding pre-treatment and post-treatment (oxide removal), mold surface carbon residue cleaning, metal surface degreasing, paint stripping, rust removal, and industrial surface preparation before coating or bonding.
High cleaning efficiency with minimal substrate impact
Non-abrasive, non-contact laser cleaning helps protect the base material and reduces the risk of deformation compared with grinding or blasting.
High-energy pulse output supports fast removal of tough contaminants such as rust, oxides, paint, carbonized deposits, and oil stains.
Designed for production sites: simple operation + mobility
User-friendly touchscreen control panel with parameter presets makes operation straightforward for workshop teams.
Universal/omni-directional wheels and compact cabinet design improve on-site mobility and productivity.
Wide material compatibility and flexible process control
Suitable for a broad range of industrial cleaning tasks and materials commonly found in manufacturing and maintenance environments.
Multiple focusing options and adjustable process settings help tailor results for different contamination types and surface conditions.
Reliable thermal management for stable long-term operation
Industrial water-cooling system improves stability and helps maintain consistent laser performance during continuous cleaning tasks.
Modular structure + upgrade-friendly architecture
Modular design simplifies service, supports customization, and helps users adapt the system to different production lines or cleaning workflows.
Optional preheating version (GST-SP500P) addresses demanding scenarios where improved process stability and cleaning consistency are desired.
Cleaner, safer, and more compliant workflow
Reduces consumables and chemical usage, helping factories move toward greener surface treatment processes while improving shop-floor cleanliness.
