GM nameplate provides hot stamping for Rockford Fosgate

GM Nameplate was able to provide Rockford Fosgate with a durable nameplate for their car stereo speakers that met all of their environmental and design requirements. The nameplate must achieve a bright metallic color and the strength to withstand foot traffic or any impacts interior car doors face. GMN found that applying the hot stamping process and using a chrome foil would best meet these requirements.

Hot stamping uses heat and pressure to transfer dried ink or foil from a roll of film to a plastic part. In this case for Rockford Fosgate, GMN used a high endurance chrome foil that is well suited for automotive applications due to its increased abrasion resistance. The chrome foil was then pressed onto a black plastic part, which was molded using resin, a thermoplastic polymer.

With the ability to decorate a two-color, two-tone part, hot stamping is less time consuming than masking or painting. Additionally, hot stamping saves production time because the dried ink or foil doesn’t need to be placed in an oven after it’s already been cured when it was transferred via heat.

No adhesive was applied to the back of the nameplate. The nameplate is developed with a few snap features that allow it to lock into the speaker.

An aluminum fixture holds the base component, which is molded using resin.

Metallic chrome foil is rolled as aluminum stamp presses down on the base component.
