Gas Fill Machines and Airbag Inflators

high-quality gas fill and airbag inflator machines
an industry standard

Cardinal Gas Fill Machines and Airbag Inflators


Multiple customers within ride control (shock absorbers and struts) and airbag inflator industries utilize Cardinal gas fill technology. In simplest terms, the product is fixtured, filled, and resistance welded to seal the stored gas. This is done at production speeds to a high degree of accuracy. Our unique approach to the manufacturing of stored gas products has made Cardinal Machine Company an industry leader in gas fill technology.

Cardinal Machine installs gas fill machines and airbag inflators worldwide in several configurations that include various ancillary processes to enhance the manufacturing process and ensure the production of high-quality gas fill machines. 


Our systems often include ancillary processes such as:

  • Automatic load/unload
  • Proofing (testing product above design pressure to verify integrity)
  • Post weighing (verifying fill accuracy via weight)
  • Venting (creating an inert product from out-of-specification parts)

Specialized In Gas Fill Technology and Airbag Inflators Manufacturing Since the Early 1990s


In the ride control market, the development of the monotube shock absorber demanded the need for equipment that could fill and seal to a much higher pressure than could be achieved with existing machines.  Additionally, both the gas fill location on the part and the part attitude within the machine tooling required machines of an entirely new design concept. 

Cardinal Gas Fill Machine

Cardinal’s solution to the need was to develop an entirely new machine platform capable of filling up to 500 psi (from a prior 50 psi maximum) and to fill from the bottom versus the top of the product.  With noticeable engineering and build improvement over the years, this basic platform still exists, with installations in the U.S., Canada, and Mexico. 


Later in the 1990s and with overwhelming success in the ride control market, Cardinal took what had been learned and developed, and began designing and building ultra-high-pressure gas fill machines specifically for the vehicle safety airbag inflator market. Initial machines were designed around a 10,000-psi fill pressure maximum.


As inflator technology advanced, the need for yet higher fill pressures arose. Cardinal answered the call, and now our standard high-pressure gas fill machines can fill and seal up to 15,000 psi.  Our machines are now state-of-the-art and considered a standard in the industry. We have over 100 installations worldwide.
