• The exchangeable compaction units are only inserted into the driving unit - further continuous adjustment after the initial adjustment is not necessary any longer.

• The mobility of the extruder has been improved by equipping it with a travel drive of it's own - that means in future the machine is able to drive back independently to the beginning the production bed - additional manoeuvring with the hall cranes is not necessary any more.

• The entire housing has been modified in a user-friendly way - by opening the side parts all important drives are made easily accessible allowing quick conversion and simple maintenance.

• Due to an integrated wire guide the complicated and recurring adjustment of the wire guide trolley is not longer necessary.

• The machine can be cleaned very quickly and carefully at the end of the production bed as we use the fast-link-system, which guarantees the quick removal of the vibrating plate. After unscrewing only a few clamping srews the vibration unit is removed and the compaction augers are laid open.

Decisive developments concerning the choice of the materials reduce the running costs compared with the traditional extruders.:

• A special material for the core of every extruder - the compaction augers - and an improved geometrical form helped to prolong their life.

• The use of chrome-molybdenum-steel for the heavy duty mechanical parts of the inner vibrators reduces the maintenance involved.

• Hardwearing HARDOX sheet for the vibration plates and the moulds also reduce the running costs.

• The development of better hardening procedure for the end pipes reduce their wear.

• The weiler vibrators which have already proved successfully on our slide moulding machines guarantee a perfect compaction of the surface of the slabs and of the webs.
