HTC Star Palette

Metal has a richness and elegance that is hard to match. Real metal has a different feel than plastic and has a high-end look to it. You can capitalize on the elegance of your metal component by adding decorative features as well. Although metal decoration can be a tricky process, GM Nameplate (GMN) has the experience and the skill set for the job.

HCT Europe, a luxury beauty product manufacturer, was working on a project for their client Alcor & Co. They began working with GMN to manufacture the aluminum outer shell of a new beauty color palette named the “Star Palette.” The designer of the palette, John Galliano, wanted it to have the appearance of an antique cigarette case from the 1920’s. On each side of the case, Giliano placed the images of two different “paper dolls” that would be embossed. The background of the palette was to be matte black, while a high-gloss black would be applied to the areas of the embossed artwork. GMN worked with the customers to provide design considerations for manufacturability of the metal shell that aligned with the intended design. In addition, this product was on a tight schedule and needed a quick turnaround for launch, which proved difficult for such an intricate part.

GMN’s Monroe, NC Division was tasked to print, emboss, and form the decorated aluminum shell. To produce this part, first the artwork was printed onto a flat sheet of hi-brite aluminum. The areas that were to be embossed were printed with a transparent high-gloss black ink, which allowed for the brilliance of the aluminum to show through, while the background was printed with a matte black ink for contrast. Using progressive Class A tooling, the aluminum shell was embossed in great detail to bring out the design of the two paper dolls, which can be challenging. GMN was able to achieve the intricate embossing on the part through extremely tight art and print registration. The press closely registered to the lines of the design in order to precisely emboss the desired area, leaving the matte finish flat and the doll designs raised. Finally, the metal sheets were formed to the shape of the palette, creating a clean and rounded edge around the entire shell. The customer wanted the artwork to come all the way down to the edge of the part, which is difficult when stretching the metal during the forming process. But after a few rounds of testing, a process was established that allowed for the part to be consistently formed without distorting the embossing or inks.

After this initial project was completed, GMN provided the customer with several prototypes we created of the same part design but with a variety of color and texture combinations. These samples provided physical representations that exemplified how you can completely transform the look of a current design just by applying different ink processes and decorative finishes.
