Method for fabricating a plastic lamina, and lamina obtained by said method |
摘要 |
A method for fabricating a plastic lamina having a sandwich-like structure comprises the steps of: 1) providing an injection-moulding apparatus with a mould which comprises two mould sections which can be moved relative to one another, in a closed first extreme position delimit a mould cavity contiguous to an injection unit, and in an open second extreme position release a moulded lamina for the removal thereof; 2) providing foaming means to cause plastic injected into the mould cavity to foam in the mould cavity; 3) providing blocking means for temporarily deactivating the foaming means; 4) actuating the blocking means; 5) actuating the injection unit in the first extreme position of the mould; 6) deactuating the blocking means; 7) deactuating the injection unit; and 8) moving the mould sections relative to one another according to the adjacent graph: <IMAGE> |
