New crossheads for
extrusion lines
Erocarb produces many types of crosshead, from
simple cartridge units for PVC to filling and jacketing
units including equipment for CV lines and various
crossheads for fluoropolymer cables and tubes.
The company’s factory with multiple NC machines
allows full control of the delivered units. A new
“T” range has now been added: crossheads for
multi-layers tubes and pipes. These crossheads are
delivered with manual centring.
Their distributors are defined for the specific
polymers used: HDPE, PEX, EVOH and adhesive.
The parameters of the distributors can be
sized to the thickness of each layer for a stable
co-extrusion process.
Even Hastelloy® execution is available for extrusion
of fluoropolymer. In this case the internal
distributor will always be heated.
The connection to the crosshead is perpendicular
or angled to the extrusion line. On multiple layers
crossheads, the layer entry correspondence to the
extruder position can be chosen freely.
