Z-Axis design for manufacturability and ease of repair. Modular design to facilitate upgrading. Interchangeable components to minimize inventory. No soldered connections - All gold plated custom connectors and pressure contacts for reliability in harsh environments. Integrally molded buttons for environmental sealing. Two shot revolving platen overmolding provides comfortable rubber user interface. Speaker Microphone Design Ideology
Substrate is a custom engineered PC/ABS blend thermoplastic polymer. Overmold is a thermoplastic elastomer alloy designed especially for bonding to the substrate PC/ABS polymer. Molded concurrently in a two shot revolving platen overmolding process for optimum quality and part integrity. Allows emergency button, push to talk (PTT) and volume control interface buttons to be integrally molded to the case, resulting in unprecedented sealing capability. Engineered Materials
