Complete Reifenhäuser extrusion line for thin-walled PP pipes
For sale is a complete extrusion line for the production of
thin-walled pipes made of polypropylene (PP). The system covers the
entire production process – from material supply and extrusion to
vacuum calibration, cooling, hauffing and length measurement to
automatic cutting and outfeeding.
The line is currently under construction at the Alicante site in Spain
and can be visited by appointment. The sale is preferably carried out
as a complete system.

2005• Drive control: frequency converter• Tube cutting: moving
Battenfeld cutting machine• Control of the cutting edge: Year of
construction 1995• Clamping range of the cutting edge: approx. 30 to
120 mm• Location: Alicante, Spain• Availability: short-term by
vote
MATERIAL SUPPLY AND RECYCLING
The material supply includes a side silo and a Mostan two-component
suction conveyor with A-B diverter. New material and processed regrind
can thus be fed into the production process.
A plastic mill with suction allows the direct shredding of rejected
parts. The regrind can then be returned to the material supply. This
enables a material-saving production cycle.
EXTRUSION AND TOOLING
The core of the system is a Reifenhäuser single-screw extruder with a
4 kW drive. The electrical system was modernized in 2005 and equipped
with a frequency converter. The scope of delivery includes two
extrusion heads as well as a tool cabinet with various calibration
sleeves and mandrels.
The existing tools are intended for the documented pipe sizes. The
exact tool stock and the respective usability should be checked
together during the inspection and recorded in the purchase
contract.
CALIBRATION AND COOLING
After extrusion, the pipe passes through a vacuum calibration section
with a cooling tank. Integrated water and vacuum pumps are used to
shape and cool the thin-walled pipes.
In addition, an air-cooled chiller is part of the system. The
refrigeration unit was built in 2015 and, according to the documents,
has been in use since 2019.
TAKE-OFF AND LENGTH MEASUREMENT
Pipe transport is carried out via a robust Graewe crawler take-off
with three-phase motor and frequency converter.
An IVO measuring wheel provides the length signal for the downstream
cutting machine. A second output is used to monitor the material flow
and can issue a safety signal in the event of a material standstill.
An additional IVO spare measuring wheel is also available.
CUTTING AND SPOUT
The rotating Battenfeld pipe cutting machine is designed for cutting
lengths of approximately 100 to 2,500 mm. According to the
documentation, existing clamps cover a range of about 30 to 120 mm.
After cutting, the pipes are ejected from the line via an automatic
pneumatic tilting table.
PERIPHERALS AND SCOPE OF DELIVERY

CONDITION AND INSPECTION
The system combines proven mechanical components from established
manufacturers with modernized electric drives and newer peripherals.
The electrical retrofit of 2005 is not the same as a complete
mechanical overhaul.
In the case of the Battenfeld cutting machine, a precautionary
inspection of the pneumatic hoses and cylinders is recommended. The
current technical condition, the functionality, the exact scope of
delivery and the available tools must be checked during an
inspection.
The plant is preferably sold in its entirety. Dismantling, loading and
transport must be agreed with the buyer. Viewing possible by
appointment at the Alicante site. Price on request.
