1 MACHINE WORKING DESCRIPTION
1.1 INTRODUCTION – WORKING DESCRIPTION
Thermoforming machines are included within the group formed by wrapping
machines.
This machine uses two film coils. The interior coil is made of plastic material
(usually a complex one, that is to say, formed by more than one component) that, by
means of different systems, when it meets the thermoforming mould adapts itself to the
shape of a fitting so creating a cavity.
Once the film cooled, it reaches the loading area, where the product to be
packed is introduced in the abovementioned cavities by means of adequate devices
that adapt themselves to the machine.
Then, the upper film is placed on the cavities and both enter a camera or
welding mould where the sealing of both plastic materials takes place. Previously, and
if the product so requires and the moulds are prepared to do so, we can create an
atmosphere modification into the package.
Finally, at the cutting unit, packs are divided by unit or by group and so they
come out of the machine ready to be presented to consumers.
