The challenges of material deformation and inconsistent coating removal are always existing when processing new energy vehicle (NEV) interior and exterior trim with lasers. Building on that foundation, this case study delves into the critical debugging points FEELTEK emphasizes when collaborating with system integrators to develop and validate laser marking process solutions for these complex components.
Removing the coating on an automotive light bar with length of 500 mm.
Project requirement:
Laser device: JPT 80W MOPA fiber laser
Working field：600*600mm
Focal length: 720mm
To achieve this result, FEELTEK and the system integrator have made concerted efforts across multiple fronts
Selecting the Appropriate Scanhead Configuration
As automotive interior and exterior trim parts are predominantly made from plastic, fiber lasers or end-pump lasers are commonly used for marking. These components are typically large, integrated pieces with complex curved surfaces.
To address these application challenges, FEELTEK offers dynamic focus systems with aperture options of 10, 20, 30, and 40 for fiber laser sources. The selection of the optimal scanner configuration is based on a comprehensive assessment of workpiece size, surface curvature variance, and focused spot size requirements.
Hardware and Software Prerequisites
To ensure marking accuracy and repeatability, providing the 3D model and marking artwork in software, along with a matched workpiece fixture in hardware, is essential. Let’s see how our engineer operates in the following video.
During the debugging process, a common issue is incomplete coating removal in a single pass due to inherent inconsistencies in the coating layer itself. This can be addressed by reducing the marking speed while increasing the laser frequency. In this specific case, FEELTEK engineers conducted precise calibration of parameters including marking speed, laser frequency, and laser energy, finely tuned to deliver:
• Flawless Surface: Complete paint removal with zero base texture.
• Crisp Edges: No burrs or imperfections.
• Substrate Integrity: Underlying material fully protected.
• Optical Clarity: Excellent light transmittance achieved.
• Peak Productivity: Maximized operational efficiency.Ready to bring this precision to your production line?
