Guala Closures has unveiled MAGNEX, a new closure for premium spirits made using electromagnetic forming technology.
The manufacturing method uses “high-velocity” magnetic pulses to shape aluminium around a mould.

This allows the production of detailed forms, micro-engravings and three-dimensional textures that are not achievable through standard aluminium forming methods.
The company said each closure is developed together with the brand, linking design features with the protection system.
The launch comes against a backdrop of growing limits in conventional protection tools such as holograms, seals and tamper-evident systems.
As similar technologies remain widely available, counterfeiters have been able to copy them with increasing precision.
This has led to a greater focus on the closure as part of product protection.
The closure uses an aluminium outer shell shaped through electromagnetic forming (EMF), together with an internal component that can also be made from recycled plastics, supporting a decreased use of virgin materials.
Combined with anti-refilling valves and tamper-evident systems, the closure brings together several layers of protection in one unit.
Manufacturing is carried out at Guala Closures’ Gartcosh site in Scotland, which the company said is currently the only facility in the closures sector with industrial-scale EMF lines.
Guala Closures group industrial and technical directorate Andrea Tassisto said: “Most anti-counterfeiting measures fight on the same technological ground as the counterfeiters. EMF changes that equation.
“The geometries and textures we achieve with MAGNEX are physically impossible to reproduce through standard embossing or metallisation, which means the design itself becomes part of the protection mechanism.”
In February, Guala Closures acquired Vinventions’ screwcap production business in Rosarito, Mexico.
The deal expanded the group’s manufacturing base in North America and boosted its supply capacity for the US wine and spirits sector.
