Ignition Safety Devices

Day & Zimmermann specializes in the design, manufacture and testing of MIL-STD-1901A compliant Ignition Safety Devices (ISD) for safe and reliable initiation of launch flight motor ignition systems. Our designs include through bulkhead initiation (TBI) that provide highly reliable ignition of pyrotechnic energy to rocket motors, while isolating the ISD from the rocket motor heat and combustion effects. Day & Zimmermann also designs ISD’s for single and multipoint initiation and ignition applications.

IM compliance dictates a MIL-STD-1901A ISD must be used for all new rocket motor designs. Our IM ready designs comply with all MIL-STD-1901A and other safety requirements Day & Zimmermann’s ISDs are suitable for a wide range of applications:

Tactical missiles
Strategic missiles
Missile defense systems
Air-to-ground, air-to-air, and ground-to-air rockets

Key Features

MIL-STD-1901A compliant
Micro-miniaturized packaging
Through bulkhead initiator design that works in-line with donor detonator
Single or multiple point initiation systems with simultaneous or sequential operation
High-reliability designs without moving parts and suitable for long term storage with BIT Manufactured in state-of-the art ISO 9001 facility

Custom Energetic Materials

Day & Zimmermann has over 75 years of experience manufacturing pyrotechnic devices and energetic pellets/powders.

We have produced a large array of custom energetic devices to meet specific customer requirements for many Department of Defense munitions and systems.

Day & Zimmermann ensures the reliability and consistent performance of each energetic device through control of in-house recrystallization, processing, and pressing of our own explosive powders. Each of our energetic components is designed to withstand severe temperature and mechanical environments without damage or degradation.

Key Capabilities

In-house powder blending and powder recrystallization
In-house pellet pressing
In-house green powder blending and recrystallization
Extensive in-house testing
- Vibration
- Drop shock
- Thermal shock
- Humidity
- Extreme temperatures
- Long-term aging
- Explosive testing

Detonators

Day & Zimmermann is a leading manufacturer of low cost high voltage EFI detonators. The EFI chip assembly consists of an exploding foil that propels a flyer (slapper) through a stand-off barrel, all of which is deposited on a PC-Board substrate, using a patented low-cost, high-reliability fabrication technique. The 4500m/s flyer has been shown to be reliable at temperatures ranging from minus 55°C to 200°C and shock resistant up to 100,000g (such as thick wall penetration).

Our EFIs have been designed into a wide variety of applications including:

Safe and arm devices
Warheads
Rocket motor initiators
Payload launch vehicles
Oil and gas exploration
Tactical missiles
Strategic missiles
Precision guided munitions
Electronic detonators
