CUT OF A TRIMMING DIE
The PSA Group in his plant in Mulhouse owns 9 ONA EDM machines, and is home to the main tool manufacturing centre for the PSA Peugeot Citroën group. The tool manufacturing centre, known as OCMB (Outillage Central Mécaniques et Bruts), is also responsible for providing tools to external car manufacturing clients. The main type of tools that are manufactured are moulds for the production of aluminium parts (casings, gearboxes, clutches, etc.), forging dies and trimming dies.
Another of the regular activities that they carry out at the PSA Peugeot tooling centre is the manufacturing of trimming dies. Wire EDM is employed both in manufacturing new dies and in the process of reusing the dies that have been heavily used; after being used, material is added and they are wire cut again.
