Laser Stripping Machine: Case Study

An automotive supplier struggled with sandblasting chassis components to remove rust before e-coating. Media embedment damaged surfaces, causing rework and delays. Traditional methods required multiple operators and generated hazardous waste requiring disposal.

Klear Laser deployed a Pulsed Laser Cleaning Machine with precise 150ns pulse width control. This parameter prevents heat transfer to the substrate while ablating rust. The RayTools scanner head ensured uniform treatment without base metal damage. Operators achieved 95% rust removal in a single pass on steel substrates.

Efficiency gains were immediate. Cycle time dropped from 45 minutes to 13 minutes per chassis frame. Labor costs decreased by 60% as one operator handled the process. Zero consumables eliminated media procurement and waste disposal expenses.

The table below quantifies the transformation:

This solution eliminated silica dust exposure risks and met all environmental compliance requirements. The laser system paid for itself within 8 months through operational savings. Clean substrate surfaces now ensure perfect e-coat adhesion, reducing field failures.

主な特徴と利点

Laser stripping represents the most advanced form of non-contact surface preparation in modern manufacturing. Klear Laser’s pulsed laser cleaning machines excel at this application by delivering precise, controlled energy to remove coatings, oxides, and contaminants without damaging base materials. Our systems outperform traditional methods through superior component engineering and intelligent process control.

The heart of our stripping capability lies in the JPT MOPA fiber laser source, offering master oscillator power amplifier architecture for unmatched pulse width flexibility from 10 to 500 nanoseconds. This range enables operators to target specific coating-substrate interactions, preventing damage to delicate materials while maximizing removal efficiency. While Raycus sources offer cost-effective continuous wave options, the MOPA design’s pulse control is essential for precision stripping applications.

Our proprietary cleaning head features a high-speed galvanometer scanning system with F-theta optics for uniform energy distribution across treatment areas up to 300mm wide. The integrated focal tracking automatically compensates for surface irregularities, maintaining optimal intensity without manual adjustment. Built-in back-reflection monitoring and temperature sensors provide real-time protection for both optics and sensitive substrates like aluminum or galvanized steel.

For rust removal, short nanosecond pulses create rapid thermal stress that shatters brittle iron oxide layers while limiting heat conduction to the base metal. This cold ablation approach preserves the metallurgical properties of thin-gauge steel and prevents distortion. The result is a clean, white-metal finish ready for immediate recoating without secondary surface treatment.

Industrial users in automotive restoration, aerospace maintenance, and heavy equipment refurbishment report 60-80% reductions in preparation time. The precision eliminates costly masking and reduces consumable expenses to virtually zero. Typical ROI occurs within 12-18 months for operations processing more than 50 square meters weekly.

産業用途

Laser stripping machines excel in demanding industrial sectors requiring precise, non-contact removal of coatings, oxides, or contaminants without substrate damage. Key applications include the automotive, aerospace, and marine industries. These machines utilize short pulse widths to ablate contaminants like rust or paint efficiently while prioritizing substrate safety through controlled energy delivery.

Automotive Sector

Laser stripping is vital for restoring classic car bodies, removing powder coatings from aluminum frames, and cleaning.connector pins. It effectively removes rust and oxidation from engine blocks and transmission components. The process ensures minimal thermal impact on surrounding areas and thin substrates.

Aerospace Sector

Critical for aircraft maintenance, laser stripping removes primers, sealants, and corrosion from wings, fuselage panels, and landing gear. It safely cleans composite materials and delicate alloys without compromising structural integrity. Precision ablation is essential for meeting stringent aviation safety standards.

Marine Sector

Laser equipment removes heavy marine barnacles, thick anti-fouling paints, and extensive rust from ship hulls and offshore platform legs. It efficiently strips coatings and corrosion from seawater-exposed steel and titanium alloys. The non-contact nature minimizes distortion on large, complex structures.

Applicable Materials Industry Comparison

Pulse width is a critical parameter: shorter pulses (nanosecond scale) enable efficient rust removal on thin automotive parts, while slightly longer pulses handle thicker marine coatings. Substrate safety is ensured through precise laser parameter tuning, preventing heat-affected zones (HAZ) and maintaining material integrity across all applications.
