Leo y releo gemini, chat gpt, foros pero nada. Quiero una máquina de limpieza laser por pulsos de unos 300w, imagino que tendría que ser china ya que mi presupuesto máximo es 10000 Euros puesta en España. ¿Alguien del foro compró una, la probó, funciona bien y podría poner el enlace a la misma? Gracias anticipadas

Following our previous post on wood cleaning, we have been searching for sample pieces and conducting tests on various types of varnishes and oil-based paints used on wooden furniture. We would now like to share the test results with you.
Equipment Features
This device is the result of six months of R&D by our development team, with targeted optimizations for wood's heat-sensitive nature and tendency for heat accumulation. As a result, single-component and two-component polyurethane and epoxy varnishes – which were previously difficult to remove with lasers – can now be effectively stripped using this wood-specific cleaning machine, without burning or charring the wood. Based on our tests, it covers the majority of wood cleaning scenarios.
For single-component/two-component epoxy varnishes and polyurethane varnishes, the equipment achieves effective and rapid cleaning results. Single-component epoxy/polyurethane varnishes are relatively easy to clean, with an efficiency approximately 1.5 times that of conventional Gaussian-beam lasers. Two-component epoxy/polyurethane varnishes, however, could not be effectively removed by conventional Gaussian-beam lasers. This is because after curing with a hardener, two-component epoxy/polyurethane varnishes form a hard, wear-resistant film. Combined with the inherently high roughness of wood, the adhesion of two-component varnishes is extremely strong. Moreover, the transparent surface of the varnish has low laser absorptivity, and forcing removal would only cause thermal accumulation and scorch the wood. Our redesigned wood-specific cleaning machine, through optimized beam quality, pulse control, and scanning trajectory, achieves lower thermal effects, reduced heat accumulation, and stronger removal capability, thereby effectively stripping two-component varnishes.
Key Considerations During Varnish Cleaning
Confirm whether the substrate is solid wood or plywood. Generally, solid wood is easier to clean than plywood. Many plywood adhesives are themselves resin-based glues, which bond particularly strongly with epoxy varnishes, making removal difficult. Of course, plywood is typically of lower value and less frequently subjected to laser maintenance or cleaning in practice, but it is important to distinguish the substrate before cleaning.
Pay attention to wood density. Generally, higher-density woods are easier to clean because their compact lignin structure and fewer hollow spaces result in slower heat accumulation and a relatively higher thermal damage threshold. For example, rosewood, ebony, teak, and oak are high-density woods and are relatively easy to clean. Conversely, low-density woods have more hollow structures, leading to rapid heat accumulation; even a slightly longer laser dwell time can quickly scorch the wood. Extra caution is required when cleaning surfaces made of pine, fir, or paulownia – it is advisable to reduce cleaning power and increase scanning speed to prevent the wood surface from rapidly reaching its damage threshold.
Final Thoughts
Laser cleaning of wood represents a highly promising niche. Traditional sanding damages the wood surface, while chemical paint stripping can penetrate into the interior. Laser cleaning, by contrast, is a non-contact, chemical-free method that is relatively fast and produces no pollution. It offers tremendous market potential and technical advantages for cultural relic restoration, residential renovation, and furniture refurbishment.

Hi all, not sure if this is the right sub, just wanted to ask some questions about an Alibaba cleaner.
I have a small workshop where I restore classic cars and am considering buying a laser cleaner.
I've been looking for a 300W machine on Alibaba and came across the one in the photos. It seems to meet my required specs and is affordable at roughly $5000.
Is a cleaner like this likely to breakdown much or run into many problems?
If anyone has experience cleaning car bodies in situ, what problems, if any, have you run into?
Does anyone have any reviews for models like this? Or recommendations for better models at a similar price point?
Thanks for any help!
This machine has both laser cleaning and laser marking functions.
