Product Descriptions
General Overview: Industrial Laser Cleaning and Surface Preparation
4JET's Laser Cleaning & Laser Surface Preparation technology introduces a laser-based approach to industrial surface preparation and cleaning processes. By using laser radiation, organic contaminants, oxides, oils, paints, and other surface impurities are removed without damage and without physical contact. Compared to conventional wet chemical or abrasive methods, the process is clean, dry, and environmentally friendly, and it does not harm the underlying substrate.
This technology plays a critical role in industries that require high process reliability and strict cleanliness standards, such as automotive manufacturing, tire production, composite material processing, glass manufacturing, restoration, pre-weld surface preparation, and battery production.
Working Principle and Technical Approach
Surface Cleaning by Laser Ablation:
In 4JET systems, laser energy focused on the surface is applied in short pulses. This high-intensity radiation heats, vaporizes, or microscopically disrupts the contamination layer, allowing it to separate from the material surface. The underlying substrate remains unaffected; the process targets only the bonding contaminant layer.
Power Range and Performance:
Laser cleaning systems typically operate with average laser power levels between 100 W and 2 kW, depending on the surface type and the nature of the contamination. Within this range, cleaning speeds of approximately 10 cm²/s to 100 cm²/s can be achieved. With higher-power systems, several square meters can be cleaned within minutes.
Laser Spot Control and Intelligent Software:
4JET systems digitally control laser spot intensity, repetition rate, and overlap parameters through fast and repeatable process recipes. Different process settings can be stored for each component and applied without the need for mechanical adjustments or tooling changes.
3D Surface Processing and SCANYWHERE Drive:
3D CAD-based laser processing contours can be programmed at the push of a button. With advanced drive systems such as SCANYWHERE, detailed and highly precise operations can be performed on complex three-dimensional component surfaces.
Technical Advantages
1. Dry and Contact-Free Process
Laser cleaning requires no dust, chemicals, or dry ice. As a result, no post-process cleaning or waste management is necessary.
2. No Damage to the Substrate
Since the laser beam targets only the contaminated layer, the substrate is cleaned without thermal damage, scratching, or deformation.
3. Low Operating Costs
The system consumes only electrical power and requires no consumables or abrasives, providing a significant long-term cost advantage.
4. Modular and Flexible Design
Laser systems can be used manually or integrated into fully automated robotic production lines.
5. Environmentally Friendly
The absence of chemicals and the minimal generation of waste significantly reduce environmental impact.
