This plastic part was decorated using hot stamping.

In part three of our plastic decorating series, we will discuss hot stamping. This is a mature technology that continues to produce high quality parts year after year. Hot stamping utilizes heat and pressure to transfer predried ink or foil from a roll of film to a plastic part. The process is achieved by running the foil between the hot stamping die, then heating the die, and finally pressing the die down to apply the foil to the part. The decorative foil will only be applied to whichever part of the plastic is raised the highest.

Through hot stamping, a two-color, two-tone part can be decorated without having to do the time-consuming tasks of masking or painting. Another benefit of this process is that the ink doesn’t need to cure. Since the foil is transferred to the plastic part via heat, there is no need to run it through an oven afterwards. Intricate details can be achieved through this process as well. However, due to machine limitations there are restrictions on size.

This is an optimal technology for achieving metallic colors, and the shiny ink tones produced are unique within plastic decorating. In addition, the foil applied during hot stamping is durable and can withstand harsh environmental conditions.  

In our next article, we’ll explore the unique technology of vacuum metallization.
