Our philosophy

Our ambition is to be a recognised and innovative specialist working on very small and medium-sized series of complex plastic parts.

Delta Plasturgy philosophy

The company was formed following the acquisition of two now merged SMEs, Joly Plastics SAS and Girau-Guyard SAS, which have historic and recognized know-how in engineering plastic materials and associated transformation technologies, as well as in-depth knowledge of their markets and fields of application.

Our teams are a small size to maintain responsiveness and proximity with our customers, but with a large enough size to allow international development of our business and transmission of our know-how.

Delta Plasturgy’s innovation according to François Fillot, CEO

« Helping our customers in their approach to innovate and set themselves apart from the competition by offering high-performance, competitive and the most global possible polymer solutions, meeting their needs, using high-performance plastic material transformation techniques, our associated know-how and our knowledge of markets and materials. »

Our history

The Delta Plasturgy group was founded in 2010 after the acquisition of two companies, Joly Plastics SAS and Girau-Guyard SAS.

It then branched out into the equipment industry sectors like industrial valves, equipment for manufacturing optics and industrial lifting systems. Joly Plastics has recently diversified in the aviation, rail, electrotechnical and medical fields. Since its beginnings, Girau-Guyard has prioritised and developed the Aviation, Defence, Communication, Electrotechnical and Medical sectors for equipment manufacturers and major aviation groups.
