UV curing in automotive manufacturing

Posted by admin on November 13, 2018


The applications of UV curing are incredibly widespread – in fact, the likelihood is that right now you are either using, sitting on, wearing or very near something that required UV curing during its manufacturing process.

Alpha-Cure is the world’s leading manufacturer of medium-pressure UV curing lamps which are used around the world in a range of industries to cure inks, coatings, varnishes, lacquers, resins and glues. A huge number of those lamps are supplied to OEMs and end users in the commercial printing sector for use in UV systems on digital, offset, flexo, litho, screen and letterpress printing presses.

Our lamps are also used in automotive manufacturing, and for this blog we’re taking a look at some of the elements of your car which have been created with the help of medium pressure UV curing lamps.


UV coating has been used in the manufacture of headlamps for over 30 years, being in both the main components of the part – the polycarbonate lens and the reflector housing. The lens needs a tough, scratch-resistant coating to protect the polycarbonate, and UV coatings provide this with an instant cure time to save money. The reflector housing is protected and sealed with UV coating.

Alloy wheels

UV curable coating can be applied to alloy wheels to protect the finish from the effects of water, ice, salt, grit and accidental scratched and light damage. The coating will be cured instantly once exposed to UV light emitted by a medium pressure lamp, ensuring quicker drying times than air or heat dried coatings.

Body panels

Another use of UV coating in automotive manufacture is the application of a UV cured clear coating on molded body panels. The benefits of a UV coating are that it is tough and durable whilst retaining flexibility, and it can be readily used on plastic panels as there is no heat involved to cure the coating, which would otherwise distort the shape. The UV coating means that it won’t crack when it is hit by objects kicked up by the tyres or other vehicles. As with all UV coatings it is a quick process, meaning production lines can move rapidly and there is no requirement for drying space.

Alpha-Cure lamps are manufactured from high quality materials by our experienced staff to ensure guaranteed curing performance and long working lifetime. Take a look at our product range here.
