4. Determination of use
The HSK manual welding extruders are suitable for the processing of the following plastic types:
LDPE, HDPE, LLDPE, PP, PVDF.
Excluded are filled or reinforced plastic types and principally all plastics having a melt index of MFI
190/5 < 0,5 g/10 min.
The processing of materials not complying with above specifications is not tolerated as there is the
danger of damaging the machine.
In special cases this specification can be extended after having contacted the manufacturer or his
authorized agents.
On putting the heated or switched-on machine aside, the corresponding stand which is delivered with
the machine has to be used. Please see to it that the machine has got a solid rest and the stand a
safe position.
If the manual welding extruder is stocked in heated or switched-on condition, special care
has to be taken to avoid any contact with easily inflammable or explosive products.
4.1 General procedure description
The extrusion welding (see Abb.1) is a manual or partial-mechanised weld
procedure. One works with weld addition from wire (supply see Abb.2) or from
granulate material which becomes in a plastification system (extrusion) melted. About
a welding shoe formed according to the seam geometry the weld addition is pressed
in the weld joint plastic as a rule by hot air of the basic material. The mass output
achievement of the machines or devices determines the maximum weld dimension
and influences the weld speed. The mass output achievement of the extrusion can
be also regulated about the potentiometer (Nr.37). The necessary pressure is
generated by the outcoming mass and the opposing force of the welder.
