our history since 1928
The company was created in 1928, following on from Amédée Bollée’s personal business, a car manufacturer since 1890. This company named at the time "Les Segments Amédée Bollée" was initially specialised in the manufacture of pistons ring for internal combustion engines.
History
In the 70s, the manufacturing successfully diversified in sealing rings for hydraulic systems and compressors.
It changed name to "Segment AB" in 1989, and since then the company turned towards developing high performance sealing rings (high temperature application –up to 1000°C -, profile optimised depending on application – full sealing or controlled leakage – with a diameter between 8 to 2100mm)
The quality of our products is assured by checks at all the different stages of production, but also at final inspection with high tech tools, in particular OGP (contactless video control), for dimensional and profiles check.
The limited liability company has been run by the Bollée family from 1928 to 1989. Since 1990, Segment AB, changed to a anonymous company with a capital of 390 270€, is under the management of the CRONITE group. In 2001 was certified IS0 9001 V2000 and in 2007 got its Aerospace certification EN9100. These certificates are kept up to date.

capabilities
Our workshops are equipped to produce rings from 8mm diameter up to 2100mm.
We make all types of rings: rectangular, conical, bull nose, Scraper ring with and without shoulder, oil control ring….. In the same manner, all the variants of cross section are available: vertical, oblique, with notches, step cut, bayonets …..
The material base for our rings is cast iron but we also work with Steel, Bronze, cobalt based metals…. Consult us with your requirements.
Different treatment and coating can also be applied to the rings depending on the requirements, as in: Chrome coating, vacuum or atmosphere heat treatment.
The flexibility in the organisation as well as our machining park allows us to make one piece and volume production of 40000.
The manufacturing lead times go from 24h up to 10 weeks depending on the type of ring and availability of the raw material. All is made to order (open). More than 40000 references of all makes are recorded in our files.
We put everything in place to adapt to your requirements (technical, reactivity, price).
Most of the alloys are sourced from Cronite Mancelle. This foundry is located on the same site and is specialised in Heat resistant alloys, the rings. The foundry holds the required quality standards to match the most severe market requirements.
The rest of the materials are sourced on the French Market from quality suppliers. Our team can help you design and manufacture to your requirements, Do not hesitate to consult us for more information.
History
“Le Segment AB” or as previously called “Les Segments Amédée Bollée”, is a company which has endured for decades.
The Bollée family is known for being inventors and innovators. All started with Ernest Sylvain Bollée who started a foundry to make bells and invents the wind turbine and the solar clock. This man had 3 sons, one of which, we will call Amédée Bollée father, would go on to invent l’Obéissante in 1873, the first steam powered car.
He had 2 sons with his wife, Amédée Bollée (fils) and Léon Bollée. The first son , Amédée, invents the petrol engine and was the first to prepare drawings for piston rings and files a patent in 1912, as for Léon, he invented the calculator.
Following the death of her husband, Mrs Amédée Bollée, with her 2 sons, creates in 1928 the company “Les Segments Amédée Bollée”.
They are also in relations with “La Mancelle de fonderie” as early a 1935 which was created with the intention to supply “Les Segments Amédée Bollée”. Already at the time the 2 companies were very closely tied as customer/supplier. Especially since the death of Léon Bollée, where La Mancelle de fonderie purchases his workshop in 1938.
In the middle of the 20th century “Les Segment Amédée Bollée” supplies automotive and aerospace companies. After the war, they concentrated more on Automotive. The business is known for supplying rings to Delage, Bugatti and other big names. They were at the time, the top supplier for 2 stroke engines and supplied roughly 600000 rings/month.
The company’s priority has always been to satisfy its customers. But also for the well-being of its employees. Already in 1929, the working week is reduced to 47 hours without a reduction of pay, le employees also enjoyed paid holidays as well as a marriage, and maternity bonus.
It is a family, a group that has played a large role for the locals and Mancelle, whether by offering employment but also helping during the war by cultivating a 7 ha farm to help the most deprived.
The business continues with its objectives all those years and in 1977 the company name chances to “Le Segment AB”. Soon afterwards in 1989 it is bought by AFE, as is “Mancelle”. Later the group changes, “Mancelle de fonderie” and Le Segment AB” are under the governance of Cronite and are part of this group since the 90s.
