HiFIRE fuseheads consist of two tin-plated metal lamellas embedded in a polymer chamber. They are clamped and welded to provide a firm mechanical connection and assured contact between the bridgewire and lamellas under all conditions.
The bridgewire is coated in a primary and secondary reactive high-energy pyrotechnic composition. Specific to each application, special coating systems protect the pyrotechnics from mechanical, chemical and thermal damage, as well as from various environmental effects. The fusehead base can be formed to customer requirement and connected to the application by crimping, soldering or welding.
The liveliness of pyrotechnics can be adjusted from extremely high to very moderate, depending on the installation and the intended effect.
