20220097263 · 2022-03-31 ·

A method for producing an object made of a polymeric material, said polymeric material having a melting temperature (T.sub.F), comprises the steps of: melting the polymeric material; after the step of melting, cooling the polymeric material below the melting temperature (T.sub.F) in a cooling zone; severing a dose from a flow of polymeric material coming from the cooling zone by means of a severing element (5); obtaining said object by shaping the dose between a male forming element and a female forming element (10) which move towards one another with a mutual movement speed, the dose having a temperature lower than said melting temperature (T.sub.F). Between a start-of-forming configuration, in which the dose is in contact with both the male forming element and the female forming element (10), and a start-of-deceleration configuration, in which the male forming element and the female forming element (10) begin to decelerate relative to one another, the mutual movement speed is greater than 10 mm/s.
