Automotive Laser Cleaning at Restoration

Lasermach provides a cleaning solution designed to provide the highest quality and efficiency to Automotive parts and Restoration. We offer several solutions to make processes move along more efficiently and cost-effectively. The latest technology can offer the best possible cleaning treatment for both pre-welding and post-welding. This ensures a seamless and robust joint that can is rust-resistant and coated for life without the need to use harsh chemicals and create waste.

Further, laser cleaning has been proven as the perfect option to not only prepare surfaces for bonding but to generate a corrosion-resistant coating for bonding.   Many clients are choosing solutions from Lasermach as the technology to use for corrosion resistance and bond prep all in one package.

Our high power new water-cooled lasers cleaners operate full-time in fully automated and integrated applications for weld preparation, contaminant oxide removal, injection mold cleaning, corrosion resistance, and bonding preparation.

The Science of Precision Cleaning and Restoration

Rust - particularly in temperate climates - is a car killer. It’s all well and good if you live in California or Spain and can leave cars out on your driveway without a care in the world, but in an often rainy place like the UK, or Germany cars can easily rot and crumble away.

This is due to the oxidisation of metal when water is left to sit and fester in whichever crevice it can find. And considering that wheel arches and sills are the first point of contact for water being flicked up from the road surface, they are normally the first casualties.

Normally, the only way to repair your car after an infestation of rust is some good old grinding, cutting and some choice fabrication.

But laser cleaning is a new affordable technology that blows the traditional rust removal methods out the water.  Cleaning a rusty grille down to nice shiny metal, the device appears to complete a two-hour job in seconds. And the great thing is that there is no hoax or camera trickery, this technology does exist!

The process is called sublimation and is the act of changing the state of metal to a gas form, skipping the liquid phase. This is achieved using high frequency bursts of micro-plasmas caused by a pulsed laser beam, which - when combined with extremely high thermal pressure and shockwaves - can be set to a certain depth to skim away a surface of rust. So the device can be set to burn away pretty much any material that is layered over metal, be it paint, filler or dreaded rust.

This laser cleaning technology will be a true game-changer in the world of car restoration. If a car’s chassis and bodywork are beyond the realms of a plug-in grinder to provide some mechanical sandpaper, sand-blasting can be used to remove even the thickest sections of corrosion, but this requires a complete strip-down and is a messy, arduous process. Therefore this handheld vacuum-like product could be the answer to every car restorer’s dreams.

What makes this laser device even more intriguing is the fact that it can have an on-board hoover system that immediately sucks up the vaporised rust, making the entire rust removal process as clean and simple as you could possibly hope for.

Preserve as much of the original material as you can.

Pierce through the layers of newer paint applications.

If you find a car with panels that have new paint applied over the original, then sand-blasting and chemical washes put that paint at risk. That forces you to make a hard decision: do you risk sacrificing part of the original color to fully remove the new layers, or do you leave it as it is? But with laser cleaning, you can get the surface cleared away layer by layer. We can remove that newer paint without touching the original material. Laser cleaning can be adjusted to remove minuscule layers of material at a time, so a first pass removes the bulk of the unwanted paint, a second time focuses on scanning and spot removing, and following passes ensure complete removal.

Remove the rust that has been corroding the vehicle.

Laser cleaning doesn’t just remove paint layer by layer. It can also scan for and destroy layers of corrosion. The machine can be set to leave the underlying material completely untouched. This means rust that is covering the entirety of a panel can be removed without putting the substrate at risk, even around folds and seams. For body panels and car parts with extensive rust damage that has even eaten away large sections of the metal, laser cleaning can preserve what remains of the part.

Keep the detailing on the surface level.

The sign of a well-preserved car isn’t just that it has as many of the original parts as possible and that there isn’t any filler, putty, or modern additions. All of the original parts need to retain the detailing and small complex patterns with little to no wear. The more fragile and striking the hood ornament is, the more critical it is to find an original and use processes that keep it in the best possible condition.

Laser cleaning doesn’t just keep one hundred percent of the remaining material in decorative elements. It also helps with number-matching. Expert car enthusiasts often look for number matching before investing in a car. Even if a car is beautifully restored on the outside, they still want the engine, transmission, and axle to match the vehicle identification number (VIN). That helps buyers trust in the authenticity of the car. But raised or engraved digits and small type are particularly susceptible to wear and tear. Sand-blasting and grinding put the small lines at too much risk and, once they’re gone, the vehicle is less attractive to any collectors who are looking for as much verification as possible.
