Double Injection Molding of a TPE Controller for the Medical Industry

TPE Controller for the Medical IndustryThe controller shown here was designed for use in hospital bed application, and required three individual injection molding processes. The front cover was double injection molded, and had the keys inserted into the mold, this process is known as "co-molding". Single injection molding was used to manufacture the rear case, and the keys utilized IMD (In Mold Decoration) to apply the symbols.

The finished controller measured 190.5mm x 69.85mm x 31.75mm, and was composed of polycarbonate and TPE. Ergonomically designed for ease of use, the buttons are laid out for easy accessibility. The unit is also completely sealed against spills for ease of cleaning. For more information on this precision double injection molded project, see the table below.
