Particle Foam Machine Division - KURTZ GmbH - #9

Manufacturers of ICF parts (Insulating Concrete Forms, elements used in housing construction) have particular requirements of these machines. Maximum throughput of shape mouldings with plastic or metal inserts are achieved on shuttle machines with, e.g. 3 cavities.

Instead of a shuttle, the rotation technology uses a rotat­ing steam chamberwith option for positioning inserts. This saves space and gives shorter cycle times.

The bed and rollerversion is used by KURTZ for mount­ing surfaces largerthan 2.5 m and very heavy moulds. The moving steam chamber moves along a machine bed; guide rails are not used.

For demanding and complex mouldings with inserts, the Rotax technology was developed. Two identical and horizontally rotatable mould halves are mounted on the fixed side. The counter part is fixed on a conventional and horizontally movable press frame. While a mould­ing is foamed inside, the operator or a robot can remove finished mouldings from the outside and can equip the mould with inserts forthe next cycle. Compared to tradi­tional processes, this technology considerably reduces the cycle times in all fields of application.

The transfertechnology uses several moulds forthe manufacture of a shape moulding. The beads are fed into a hot mould and sintered togetherwith the assist­ance of steam. After a brief period in which the pressure of the foam is reduced, they are "transferred" to the cold mould. Contact of the moulding with the relatively cold mould walls cools the foam further and stabilises it to such an extent that the moulding can be removed, This enables high productivity in combination with low energy consumption. The possibilities for inserts and lamination open up further areas of application.

KURTZ also offers solutions for the manufacture of floor heating panels with sound insulation and two densities, also based on the transfertechnology.
