Abstract
Process for assembling foundry core or mould elements which are rigid and have a certain porosity, one of the elements having >=1 sealing hole issuing at a free surface of the second element in which it is formed and at a surface adjacent the other element. A plastic material in a liquid or pasty form is introduced under pressure into each hole from the free surface and the plastic material is made to penetrate into the porous material forming the mould or core elements. The sealing material is a "hotmelt" thermoplastic whose m.pt. is 80-250 degrees C and it is introduced at a low pressure. This gives quickly made and highly resistant connections between the mould or core elements.
