New addition to range
at Rosendahl
Rosendahl has developed a new addition
to its Rocomat series – the Rocomat 5L,
especially designed for the processing of
flame retardant materials. The innovation
features the possibility of an increased
output quantity, eg 400l/h PVC, which is
being mastered by the same system.
The Rocomat 5L is developed with the
same design as the preceding model,
with a rotating shaft in the crosshead. The
crosshead is designed in a larger format
with deeper channels in order to reduce
the pressure build-up.
A shorter extruder adaptor favours the
flame retardant materials, since the
colour change takes place inside the
shaft, which requires that only the mass
within the distributor shaft needs to be
rinsed. Additionally, this process results in
minor colour change lengths for the flame
retardant materials.
This gives the possibility to purge the
unused extruder or to use this extruder
for an inner skin layer. The colour change
shaft is also used to realise the bypass
function on all extruders. This unique
solution is applicable in any Rosendahl
automotive line.
Some processes are: change of layer, which
requires two extruders, skin or strip change
– three extruders as well as layer and strip
changes which requires four extruders.
