Bonjour,

Je pense à "mouton à chute libre" mais je ne suis pas très sûr. Je pense qu'il pourrait s'agir d'un "marteau-pilon" plutôt.

Je me suis basé sur : http://www.wipo.int/pctdb/fr/wo.jsp?wo=1994014539

Merci !

XXXXX retails the UK`s only remaining significant drop hammer company. This comprises 5 drop hammers, including one which has the largest bed in Europe. This facility also has dual form capability, which gives us the ability to reverse engineer pressings from sample part, therefore eliminating the need for expensive drop hammer tooling for small production runs. Full interstage heat treatments are also available on site.
