Teledyne RISI specializes in the manufacture of precision secondary explosive components including initiators and detonators utilizing the Exploding Bridgewire (EBW) and Exploding Foil (EFI) concepts. EBW and EFI devices manufactured by Teledyne RISI contain no primary explosives such as are commonly used in “blasting caps.”
Both the EBW and EFI concepts rely on the rapid discharge of electrical energy to vaporize a wire or foil to directly initiate a secondary explosive. EBW and EFI detonators are immune to accidental initiation by radio transmission, static charges or proximity to high tension wires.
Teledyne RISI also distributes and manufactures a wide selection of Electronic Firing Systems for use in initiating EBW and EFI detonators in the field or in research laboratories.
At Teledyne RISI our priorities are Safety and Quality. Period.
