Description of the machine
The
Shannon HRT/D
plastic bending machine is a rapidly
convertible machine for the production of very large series of
items with multiple bends for the plastic sheet processing
industry.
The machine has three adjustable heating elements as
standard. The temperature of which can be adjusted
independently by electronic controls.
The filaments of the heating elements on the working
surface are adjustable in height.
The work piece can be heated from one side and it is
possible to bend sheet up to 8 mm thick.
This machine is equipped with an easily adjustable and
controllable transport- and feed system. Multiple feed belts
transport the work piece over the heating elements from
the right to the left of the working surface. This way all the
sheets are equally heated and the full table length is in use.
The working surface is made of scratch-resistant solid core
material with which the space between the zones to be
heated can be filled to support the plastic sheet.
When heated, thermoplastics become so flexible that they can
be shaped. When a plastic sheet is heated to its softening point
in a narrow zone, if can be bent to any angle desired.
The bending radius is determined by the width of the heated
zone. The zone is determined by the thickness of the material,
the type of heating element and the distance between the
plastic and the filament.
Every plastic has its specific softening point. By co-ordinating
the temperature, heated zone and heating time all kinds of
thermoplastic can be processed.
