The
extrusion process is an integral part of any manufacturing process. The
extrusion process is performed to create and produce hollow and fixed
cross-sectional profiles of objects such as tubes and rods. Extrusion plays an
essential part in the insulation of cables as well.
The entire process of extrusion is divided
into three parts:-
●
Melting the plastic via an extruder
● Formation of plastic via a die
●
A downstream equipment
Thus,
we can infer that the extrusion process has two major components.
●
An extruder machine is used for the production of long
continuous products.
●
A caterpillar
haul-off machine, inclusive of an extrusion machine, is used in the
extrusion process to heat polyethylene, PVC, etc, to protect the cable.
Caterpillar haul-off
machine
Caterpillar
haul-off machines are used in synchronization with extruders and production
lines. They are generally suited for molding PVC, PE, ABS, and PP. The
haul-offs control the extrusion speed and positioning of the caterpillar. They
make use of the vector motors providing constant pulling power.
Some
key features of a Caterpillar
haul-off machine include:-
●
Caterpillar V belt
●
Timing belt
●
Standard haul off
●
Electro mechanical switch
Extrusion machine
The
extrusion machine works as a functional part of the whole machine consisting of
a cooling water tank, blow-dry, printer, capstan, take-up and arrangement
machine, etc. Since the extrusion machine is the critical equipment of the
machine, the demands for tailormade extrusion machines are expanding. XLPE cables extrusion machine suppliers are
aiming to adapt to the demands of:-
●
XLPE cable extrusion
●
HFFR cable extrusion
●
LSZH cables extrusion
One
must look for a well-recognized XLPE
cables extrusion machine supplier to ensure a safe and secure process.
Conclusion
With
the increment in the use and needs of premium quality of XLPE cable lines, the
process shall be performed and controlled accurately and precisely. For the
purpose of smooth and proper functioning, emphasis shall be on the correct
process and its implementation. The right pieces of equipment shall be examined
properly before putting into use.
One
must also be aware of the consequences of poor quality of insulation of cable
wire and using wrong extrusion technologies. The faulty wires can lead to short
circuits and devastating fire accidents leading to human and property loss.
Hence,
it is essential to understand the extrusion process and the right technology of
extrusion and extruders.
