Mini-Flex Corporation

Mini-Flex Corporation is a family owned metal bellows manufacturer in Ventura, California. It designs and makes metal bellows, metal bellows assemblies and complete bellows systems.

The company was founded in 1961 and is celebrating 65 years in 2026. The founder, Poul Jorgensen, built the first bellows forming machine in 1959. Early customers included Aero Flex, General Atomics, Hughes Aircraft, Litton Industries and Westinghouse.

The site says Mini-Flex was the first bellows maker to carry a full line of stock bellows. It keeps hundreds of stock bellows and thousands of overruns, with quick lead times. Stock bellows are listed in a data list and a metal bellows catalog.

Custom bellows are designed from existing stock bellows to meet a customer's needs. The site says the company makes bellows assemblies for uses from cost effective applications to spaceflight applications.

The company offers bellows production services such as welding, brazing, machining, heat treatment, cleaning and tubing. Finishing services include electropolish, passivation and plating.

The site says the company developed forming techniques for very small hydro-formed bellows. It says the company works with customers across a broad range of applications.
