3 Transport and Storage
3.1 Transport
•
Before transport and storage, make
sure that the hand extruder has cooled down
to safe-to-touch temperature.
•
Hold and touch the hand extruder only on
the handles provided for this purpose.
Do not touch bare metal parts (including the hot
air hood) – whether with or without gloves –
before having made sure that they are safe to
touch. These parts reach temperatures of up to
350 °C during operation.
D02-0001
•
Always transport or store the hand extruder in
such a way as to preclude any mechanical loads
on the attachments.
If parts have been removed for transport
purposes, mount and fasten them carefully before
restarting the hand extruder!
Transport of the hand extruder in MUNSCH’s
original shipping case is recommended.
3.2 Storage
•
Store the hand extruder in a dry and frost-free
place.
•
Protect the hand extruder from unauthorized
access.
•
Special preservation is not required.
3.3 Return to Munsch
Should it become necessary to return the hand
extruder to MUNSCH Kunststoff-Schweißtechnik
GmbH, always use the original shipping case.
4 Product Description
4.1 Application range
The application range of the hand extruder is defined
by the data on the type tag and the service limits
indicated in these operating instructions.
CAUTION Operation of the hand extruder outside
the service limits stated in these operating
instructions is subject to the Manufacturer’s prior
approval.
4.2 General
Type MEK is a hand extruder with external air
supply.
Type MAK is a hand extruder with integrated air
supply (Autoair).
For both types of hand extruder, the following
parameters can be freely selected:
-
welding rate,
-
hot air temperature,
-
melt temperature and throughput; the melt
throughput can be controlled downward from the
maximum value,
firstly by using 4 mm instead of 5 mm welding
rod and, secondly, by reducing the speed using
the fine-tuning button on the drive.
CAUTION Too low a speed will cause a risk of drive
overheating!
Driven by a powerful electric motor (1), the welding rod (2)
is fed into the extruder (3) and granulated by the extruder
screw in the process. The screw forces the granulate into
the extruder nozzle, melting it into a homogeneous,
completely plastified mass. As the molten material exits
the extruder nozzle, it is moulded by a welding shoe (4) to
the geometry of the weld seam to be deposited.
Preheating of the base material to be joined is
accomplished by a preheating nozzle (5) which is supplied
from an integrated hot air unit (6). Air is supplied either
from an external compressor or an on-board blower .
