FEATURES OF INDIRECT EXTRUSIONFEATURES OF INDIRECT EXTRUSION

ADVANTAGES DISADVANTAGES

☺ No friction between liner and billet, Longer billets result in longer contactresulting in lower extrusion load or time and hence higher thermal loadlonger billets at the same extrusion load

☺ Higher extrusion speed Limited section width

☺ Smaller discards Higher loaded stems

☺ Higher quality of extruded product Good billet surface required

CONTAINER HEATINGCONTAINER HEATING-- AND COOLINGAND COOLING--SYSTEMSSYSTEMS

INDUCTION HEATING

☺ high power-density with short heating-period

☺ robust execution and high long-term use, due to special insulation-materials

☺ low running-voltage

bad control of temperature

no possibility for zone-heating

INSTALLATION OF INDUCTION HEATING

22BEG 2007 _



RESISTANCE HEATING

☺ easy change of a broken cartridge

☺ with a breakdown of one broken cartridge and a parallel switching,

no process disturbing occurs

☺ easy handling of spare-parts

☺ more heating zones in axial direction are possible

high sensitiveness through vibrations

worth warmth-transition and therefore possible selfsuperheat, this means also a shorter life-time

CONTAINERCONTAINER--REFITTINGREFITTING--CENTRECENTRE

• Top head furnace electrical heated

• Container refitting centre was started in October 2002

• Total heat power: 10000 m³ / h

• Max. size of parts: - diameter 2000 mm- high 2300 mm

• Range of temperature: max. 520 °C

• Operational weight: max. 20 to

• Short delivery time

29BEG 2007 _


CONTAINERCONTAINER--REFITTINGREFITTING--CENTRECENTREOur service includes far more then refitting the liner. By checking and keeping track of

important data such as the exact dimensions, hardness, deformation etc., we can form

a detailed picture of the container, which can help in deciding on the appropriate

material, shrink-fit parameters etc.
