Abstract (en)
[origin: EP0098405A1] 1. Process for producing large format green sand moulded parts by means of boxless moulding, whereby sand is filled in a mould and compressed by applying pressure via a film is that during a first filling stage I, the green moulding sand (5) is applied on a pattern (1) on all sides in one layer in a moulding box (4), which limits the sand surface on the pattern plate (2) and via a spinner (7) which rotates at reduced speed in order to protect the pattern, and is then covered with a flexible film and compressed and during a second filling stage II the back-up (6) is finally applied and the mould subject to final compression.
