Additionally, their ability to clean delicate surfaces while minimizing damage increases their value in industries like manufacturing.
Industrial Laser Cleaning Machine Price
There is no fixed standard for laser cleaning machine prices—only a general price range. This is because most laser cleaners are custom-built to match specific application needs, with configurations and performance parameters adjusted accordingly, which directly affects the cost.
Take a 200W handheld laser cleaning machine as an example. Configuration requirements vary significantly by use case:
Tire mold rust, paint, and carbon removal: Prioritizes high cleaning speed, often requiring a PIC-based control system for faster response.
Chip or PCB coating removal: The cleaning process must be more gentle and delicate, with zero damage to the surface; focuses on real-time data collection and feedback during the cleaning process, which may require a PLC control system.
Other customizable factors that influence pricing include:
Beam profile (Gaussian vs. flat-top)
Laser mode (pulsed vs. continuous)
Interface type (QCS or QBH)
Fiber length, f-theta lens focal depth, output power, pulse width, and scanning speed
| Power | Type | Price range (USD) |
| 100W~300W | Pulse laser cleaning machine | $10,000 ~ $50,000 |
| 1000W | CW laser cleaning machine | $3,000 ~ $10,000 |
The price difference of handheld laser cleaning machines is primarily determined by the type of laser source used. Laser sources are generally categorized into continuous wave (CW) and pulsed types:
