Abstract
A method for producing parts from polymer in a mould comprising first and second mould portions that can be moved relative to each other, comprising: —closing (202) the mould in order to form a first injection cavity connected to an injection device by the first mould portion, —injecting (204) material into the first injection cavity in order to form a first part, —moving (206) one of the mould portions relative to the other, the first part remaining connected to the second mould portion, —closing (208) the mould to form: a second injection cavity connected to the injection device by the first mould portion, and a first solidification cavity in which the first part is disposed, —injecting (210) material into the second injection cavity to form a second part and simultaneously solidifying the first part disposed in the first solidification cavity.
