Multi-axis, computer controlled Entec filament winding machines
are used to produce a variety of composite structures
including pressure vessels, accumulators, pressure housings,
composite nozzles, shafts and tubes. We also specialize
in thick-walled composite structures as well
as hand-layed up, autoclave cured laminates. Cobham can take
your requirements through initial concept, to engineering design
and qualification, and finally long-term production.
A design for Six Sigma philosophy is the key to our
development process. The Lean Six Sigma perspective focuses on all
aspects of the business from initial customer contact to delivery
of the finished product.
Through our Excellence in Delivery Programs, we reduce
overall manufacturing lead times by deploying innovative supply
chain logistics and internal processes. This provides our customers
with the best possible lead times for exact quantities
desired.

Modern Facility
Our 40,000 square foot facility is fully equipped to design,
manufacture, test and inspect composite structures. We are
ISO 9001 and AS9100 certified. Our test and inspection
systems and equipment are selected specifically to support
validation of the integrity of our products. These systems
include a 6 axis ultrasonic scanning system, an infrared
thermography system, a CMM, a class 10,000 and
100,000 clean room, and a helium mass
spectrometer.
Testing and Inspection
Cobham certified technicians perform burst testing to 30,000
psi, hydrostatic proof pressure testing and expansion testing,
pressure cycle testing, helium mass spectrometer leak testing, IR
thermography inspection,
and impact, shock, and gunfire testing.
Customer Care
As the OEM with engineering expertise and highly trained
technicians, Cobham can offer the kind of quality maintenance that
can make the difference between condemning a damaged cylinder or
restoring it to full use.
Cobham in Westminster, MD is an Authorized DOT Requalification
Facility per 49 CFR (CFFC/FRP/3AL). Additional service capability
includes: Oxygen Cleanliness Certification to RR-C-901C and
cylinder refurbishment.
