DESCRIPTION OF THE MACHINE
The
Shannon AFF/D
bending machine is a semi-automatic machine for the production of large series of
items with one or two bends for the plastic sheet processing industry.
The machine has two heating elements. The temperature of which can be adjusted by electronic controls.
The heating elements which are mounted in the pneumatically operated top frame are adjustable in height
in respect of the working surface.
One of the heating elements can be moved in the top frame to create a certain distance between the 2
bends.
The workpiece can be heated from one side by contact, reducing the production cycle time and making it
possible to bend sheet up to 1 mm thick.
The top frame is switched on independently of the control unit and is controlled by an adjustable timer.
The working surface is made of scratch-resistant solid core material 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 and the type of heating element.
Every plastic has its specific softening point. By coordinating the temperature, heated zone and the heating
time all kinds of thermoplastic can be processed.
