In-Mold Decoration RSPI sources in-mold decorated (IMD) panels from a select group of high quality manufacturers in China.  There are many advantages to choosing IMD;
Print a Variety of Stunning Graphic Images. Mass Customization with Assorted Images Using a Single Mold Lenses, backlit, EMI/RFI shielding. Integrated Keypads Surface Textures & Hard Coating (Scratch Resistant)

Production Steps   

The first step in IMD is very much like printing a membrane switch overlay. The image is printed on high quality polycarbonate using special heat resistant inks on the first or second-surface.  Good quality film is essential, with controlled gauge (thickness), clarity, and minimal internal stress.

The printed film then needs to be formed to fit the profile of the injection mold. The image is either thermoformed or vacuum formed to the final shape.

Once the printed part is formed, it is trimmed to fit the mold cavity. It is then manually or robotically inserted into the plastic injection mold. The mold closes to hold the part in place and the melted polymer is injected, coming in contact with the back of the printed image. The polymer fuses onto the back of the film, and the materials are bonded together. The part is now complete and no post-processing is required

Polycarbonate, Acrylic, ABS, and blends are the most common plastics used.
