<p>To obtain the possibility of manufacturing shell-formed objects of plastic material even reinforced, in such a way that no particular ventilation of the working space is required, it is suggested that a well prepared closed formation room (5) formed by a male mould (4) and a female mould (3) is applied into a press (1) and encased in a mould cassette (2) comprising said male and female moulds (4, 3) and then that the plastic material introduced into the formation room (5) is subjected to a necessary pressure either by pressurizing a press body (12) being a part of the press and having a form corresponding to one side of the mould cassette in order to press out the plastic material supplied into the formation room (5) before application of the mould cassette into the press (1) by compressing the mould cassette to a predetermined form against a second press body (7) being a part of the press and having a form corresponding to the second side of the mould cassette, or by injecting the plastic material under pressure into the formation room (5) of the mould cassette (2) being determined as to its form by said press bodies (7, 12) of the pressurized press.</p> |
