Production tool

Thanks to its know-how and its equipment, LBI is at your service to offer you a wide range of parts made to measure according to your needs. The various manufacturing steps are meticulously monitored by an experienced and highly qualified team.


Everything starts with the development of the alloy you have selected, standard alloy or developed specifically for you.

Casting by centrifugation, horizontal and vertical, allows the production of perfectly uniform and more resistant parts. Casting by centrifugation is casting under centrifugal pressure which causes very significant degassing within the alloy which rejects all the impurities that a bath of liquid metal may contain into the bore.

Centrifugal casting then gives the shape that you have defined for us: tubes, rings, crowns, rings, sockets, flanged cobs.

This manufacturing process, LBI applies it to small parts as well as certain parts with larger diameters. Indeed, LBI offers its customers parts with non-standard dimensions, reaching 6,000 mm in diameter and up to 20 t.

Likewise, production is dedicated to unique pieces as well as small series (from 5 to 10 pieces up to approximately 200 pieces). Whether it is unique pieces or small series by delivery, we will have manufacturing resources adapted to your request.

After a heat treatment carriedout if necessary, your part will join our machining workshop dedicated to machining operations allowing to deliver parts to the dimensions you want, whether they are blanks or fully machined parts ready to be integrated.

The implementation of a continuous and reasoned investment policy allows the regular renewal of its equipment, so as to offer cast parts at the best cost and in the best conditions.
