Laser rust removal machine is a technology increasingly used for a variety of applications, including welding pre- and post-treatments, coating removal, and decontamination. Using a handheld laser cleaner, you can remove rust and contaminants efficiently and quickly, and you can choose the parts to be removed and realize the automation of cleaning.
After this first sector, the technology was applied to paint stripping from airplanes by J. F. Asmus and through the years has attracted interest from a wide range of industries. The main advantage is that it is an eco-friendly, cost-effective process typically used to remove rust, paint, grease, oxide, and other contaminants from molds and metal surfaces, without the need to involve hazardous chemicals or aggressive processes such as sandblasting, which can damage the underlying material. Market reports predict the global laser cleaning market will reach almost $745 billion by 2026 at a compound annual growth rate of around 4.3%.2 The three main market drivers include the need for automated cleaning processes brought about by miniaturization and Industry 4.0, which has prompted the need to offer adaptable systems that can be used across multiple parts and processes; automotive and aerospace manufacturers’ need for a fast and simple way to treat and clean composite parts before bonding to ensure the integrity of the frame’s structure; and the need for cleaning systems for increasingly small electronic components, such as connectors, insulators, pads, and semiconductors.

Principle Of Laser Cleaning Technology
The process of pulsed laser cleaning depends on the characteristics of the optical pulse generated by the laser, and is based on the photophysical reaction caused by the interaction between high-intensity beam, short pulse laser and pollution layer. Its physical principle can be summarized as follows:
a) The beam emitted by the laser is absorbed by the pollution layer on the surface to be treated;
b) The absorption of large energy forms rapidly expanding plasma (highly ionized unstable gas) and produces shock waves;
c) The shock wave turns the pollutants into fragments and is removed;
d) The light pulse width must be short enough to avoid heat accumulation that destroys the treated surface;
e) Experiments show that when there are oxides on the metal surface, the plasma occurs on the metal surface.
The plasma is generated only when the energy density is higher than the threshold, which depends on the contaminated layer or oxide layer removed. This threshold effect is very important for effective cleaning while ensuring the safety of the substrate material. There is a second threshold for the emergence of plasma. If the energy density exceeds this threshold, the base material will be destroyed. In order to effectively clean the substrate material on the premise of ensuring the safety of the substrate material, the laser parameters must be adjusted according to the situation, so that the energy density of the optical pulse is strictly between the two thresholds.
Small-Area Laser Paint Removal
IGOLDENCNC Laser, we offer laser cleaning solutions that are ideal to remove paint and other coatings from targeted areas of your assets. Whether the area is inches or a few feet, our laser cleaning solutions offer a complete cleaning method – both the cleaning and clean-up is all done in one step with the handheld optic. Through the process of laser ablation, the coatings are removed to the bare metal without affecting the integrity.
Our technology can be used safely next to valuable electronics, other equipment, or people, and our laser cleaning solutions clean the desired area without interacting or bothering anything around it. When compared to blasting, abrasives, or needle gun cleaning, laser ablation is a far superior method of removing small area coatings.
