To address rising gold cost pressure, sustainability expectations and the need for consistent luxury finishes, NTI Nanofilm supports manufacturers through a cleaner PVD gold coating route. Unlike conventional wet electroplating, PVD is a dry, vacuum-based coating process. It does not require electroplating baths or chemical rinsing during the coating stage. Instead, gold or gold-tone finishes are deposited as ultra-thin films in a controlled vacuum chamber, giving manufacturers better control over coating thickness, colour tone, surface quality and material usage. This allows luxury manufacturers to achieve refined gold finishes with greater production consistency and precise control over gold consumption. NTI's PVD sputtering technology supports both genuine gold coatings and a wide range of gold-inspired finishes, enabling premium surface quality, consistent colour, design flexibility and differentiated luxury aesthetics. Together, these solutions help jewellery and luxury goods manufacturers maintain premium gold aesthetics while moving towards a cleaner, more controlled and commercially flexible surface finishing process. By moving from conventional wet chemical gold plating to PVD gold coating, manufacturers can address multiple business priorities at once. Lower gold usage and coating cost For suitable decorative applications, precisely controlled PVD Au layers can be deposited thinner than conventional electroplated layers, reducing gold consumption and material cost per component. ESG compliant The dry PVD coating route reduces reliance on chemical-intensive wet processes, supporting cleaner production with lower exposure to electroplating baths, wet chemical solvents and metal-bearing wastewater. Greater flexibility with gold finishing With NTI's PVD sputtering technology, brands can achieve premium gold aesthetics while expanding their product offerings and creating greater design variation.
