Freudenberg Joints Elastomères, which currently manufactures 100 % of its products for diesel and petrol applications, will see this activity very significantly reduced in the coming years: The current annual production of EUR 10M per year would increase in 2021 to only EUR 7 million = -30 % The Langres plant is currently developing a pilot production line of highly innovative foldable battery seals. This one is for the moment manual and performs prototyping. The objective of this development is to achieve the creation of a highly automated/robotised production line applied to very large joints. This line will then be duplicated: 4 lines in anticipation of 2023 The project opens a perspective (experimental development), which could introduce the “after technology”, the fuel cell with the production of parts called Gaz Diffusion Layer which are the core of a fuel cell => base of the Freudenberg engine seeks to maintain a technological advance, in particular to counter competing solutions and go further than existing patents: (spot 7 object: plastic)
