Abstract (en)
[origin: EP0366902A2] The invention relates to a method of ramming foundry mould material by the sudden expansion of a compressed gas. What is essential here is that, within a single pressure shock, initially a relatively low and subsequently a high pressure gradient is produced. The invention also relates to an installation for carrying out this process. <IMAGE>
