The development of door handles with antibacterial treatment has become a high value-added technical solution for sectors such as healthcare, public facilities, and even advanced residential construction. All of these increasingly demand components capable of minimising microbiological risks without compromising mechanical performance or design.
Antibacterial handles manufactured from zamak represent a significant advancement over traditional solutions, thanks to the combination of the material’s intrinsic properties and the application of advanced surface treatments.
Zamak as a Base for High-Demand Applications
Zamak, a zinc alloy with aluminium, magnesium and copper, offers an excellent balance of mechanical strength, dimensional stability, and the ability to reproduce complex geometries through die casting. These characteristics make it an ideal option for manufacturing door handles intended for intensive use.
Furthermore, its compatibility with multiple surface finishes—such as zinc plating, nickel plating or chrome plating—allows for the incorporation of specific functional layers, including antibacterial treatments, without compromising the integrity of the component or its in-service performance.
Antibacterial Treatment Technologies
When we refer to door handles with antibacterial treatment, we are not talking about applying an additional coating onto the part, but rather integrating this functionality directly into the finishing processes already used at Jegan. These include zinc plating, chrome plating, PVD or cataphoresis, which combine corrosion protection, mechanical durability, aesthetics and antibacterial properties in a uniform and reliable manner.
Processes such as electrolytic zinc plating, whether barrel or rack plating, allow precise control over coating thickness and uniformity, creating a stable base onto which additional functionalities can be incorporated without affecting the geometry or strength of the part. Similarly, finishes such as chrome plating, PVD or cataphoresis (KTL) offer high repeatability and stability, making them ideal for critical components subject to frequent contact, including passage door handles and emergency door handles, where safety and durability are essential. In applications such as these, where contact is constant and conditions are demanding, the antibacterial treatment must remain effective over time.
Integration of the Treatment into the Production Process
One of the technical challenges in manufacturing door handles with antibacterial properties is the correct integration of the treatment within a highly controlled industrial process. It is not simply a matter of surface application, but of ensuring adhesion, uniformity and repeatability of the coating.
In this regard, having an integrated production process, from zamak injection to final finishes, makes it possible to optimise critical parameters such as:
- Surface preparation (degreasing, pickling, activation)
- Control of coating thickness
- Uniformity in the deposition of active agents
- Verification through microbiological and resistance testing
This approach ensures that antibacterial handles meet demanding standards in terms of both quality and technical functionality.
Applications and Regulatory Requirements for Zamak Handles with Antibacterial Treatment
Door handles with antibacterial treatment are used in a wide range of environments where the transmission of pathogens via contact surfaces is a significant risk factor. These include hospitals and healthcare centres of all kinds—such as physiotherapy or dental practices—as well as care homes and social healthcare environments, educational facilities, and public buildings with high footfall throughout the day.
In addition to functionality, solutions must comply with specific technical and regulatory requirements, both in terms of coating resistance and the validation of antibacterial activity. Testing under recognised standards—such as those evaluating bacterial reduction on treated surfaces—and durability tests against abrasion, cleaning or chemical agents are key to ensuring the component’s performance throughout its service life.
Zamak Manufacturing: Added Value in Design and Engineering
Beyond functionality, antibacterial handles must also meet criteria relating to ergonomics, aesthetics and compatibility with locking systems. The use of zamak enables the development of customised designs, optimised both structurally and in terms of integration within the overall door assembly.
In the case of passage door handles, where user experience and perception are key factors, it is possible to combine high-quality decorative finishes with advanced technical performance, without compromising either aspect.
Likewise, early collaboration with engineering and design teams allows the product to be adapted to specific customer requirements, optimising aspects such as weight, resistance to intensive use, and ease of installation.
