Explore our core selection of industrial-grade welding, cladding, and surface restoration machinery manufactured under rigorous quality control standards.
In modern global manufacturing, standard methods of rust, paint, and oxide removal—such as sandblasting, chemical pickling, and mechanical grinding—increasingly fall short of strict environmental regulations and high-precision requirements. Laser "Togli Ruggine" (Rust Removal) technology represents a paradigm shift. Utilizing high-frequency, short-pulse laser beams, this technology vaporizes surface contaminants without altering or damaging the underlying substrate.
As a leading supplier and manufacturer, we align our R&D with global industrial shifts. Transitioning to green manufacturing requires clean, energy-efficient cleaning solutions. By integrating state-of-the-art optical systems and robust mechanical platforms, our laser cleaning systems provide repeatable, high-throughput surface preparation ideal for sectors demanding precise bonding or weld-ready finishes.
Substrate Integrity: Operates strictly above the ablation threshold of contaminants but below the damage threshold of metals.
Eco-Friendly Operations: Zero secondary chemical waste, avoiding hazardous disposal costs and complying with European REACH/EPA standards.
Operational Efficiency: Eliminates consumable requirements, yielding lower total cost of ownership (TCO) compared to traditional processes.
Unlocking value through vertical integration, rapid custom prototyping, and robust component ecosystems.
By manufacturing in Shanghai's advanced industrial corridor, we source core optoelectronic modules, heavy-duty gantry components, and precision CNC controllers locally. This allows us to pass cost efficiencies directly onto our global customers.
Our dedicated laboratory engineers design tailored optical laser paths, custom pulse configurations (MOPA), and specialized robotic integrations. We adapt machinery to clean and clad complex profiles, including internal pipe walls and heavy valves.
Every laser source and mechanical gantry undergoes continuous 72-hour thermal stress and positioning accuracy testing. Optical alignment is checked via advanced beam profilers, ensuring consistent power output and minimal heat-affected zones (HAZ).

Addressing key industrial procurement and technical operation concerns for laser rust cleaning and PTA cladding equipment.
It refers to laser-based rust and oxide layer removal. The system focuses high-intensity pulsed laser beams on rusted surfaces. The rust layer absorbs the energy and quickly vaporizes or ablates, while the metal base reflects the laser energy, preventing structural or cosmetic damage.
MOPA (Master Oscillator Power Amplifier) lasers allow adjustable pulse widths, frequencies, and peak powers, making them ideal for precise cleaning on sensitive metals (e.g. aluminum, stainless steel) without inducing surface thermal stress. Continuous Wave lasers deliver continuous output, offering fast processing speeds for large surfaces with thick rust layers (e.g. shipbuilding, steel frames).
We perform full laser beam profiling, 3D mechanical tolerances checking, and extensive component stress testing. We utilize recognized brands for laser sources and motion control systems to ensure reliable long-term operations.
Yes. Our systems feature standardized communication protocols (Modbus, Profinet, or EtherCAT) to integrate with industrial robots (e.g. Kuka, Fanuc, ABB). This allows for fully automated, offline path-programmed surface processing.
