摘要

An apparatus comprises a punch arrangement and a die arrangement that are opposite one another and closable for defining a forming chamber in which an object can be compression-moulded from a dose of plastics, a punch included in the punch arrangement and two parts that are mutually movable for forming a portion of the object provided with undercuts. The punch arrangement comprises an annular forming element for forming an edge zone of the object, the annular forming element and the punch being mutually movable whilst the dose fills the forming chamber.
