Operating Procedure

!
Turn the isolator switch situated at the rear of the machine to the ON position.
!
Using the heater controls turn the zones on to provide power to the heaters. It usually
takes between 10 and 15 minutes before the heaters have reached their operating
temperature.
!
Place your mould onto the drape table. See the section dealing with mould design to
ensure that your mould is suitable.
!
Place the table into the lower position by pushing the table lever (13) away from you.
!
Open the material clamps (4) and raise the clamp frame.
!
Position a sheet of plastic over the aperture. See the section dealing with plastics to
ensure that your material is suitable.
!
Pull the clamp frame down and close the material clamps. The plastic should
completely cover the white seals around the aperture. Use the adjusting screws at
the front and rear of the material clamps to properly grip the plastic.
!
After the heater has reached operating temperature, pull it forward over the plastic.
!
As the plastic heats up it will begin to rise slightly. It will then soften and begin to drop
back.
!
If the heating cycle time is known then the timer can be set.
!
If not using the timer push the heater back slightly to test the softness of the plastic.
Continue heating until it is soft enough to form.
!
At this point, push back the heater all the way. Turn on the vacuum pump (7) and
raise the table (9) until you can feel it lock into place.
!
Let the finished moulding cool down a little, then pull the Vacuum/Pressure valve (6)
downwards. This will blow air between the mould and the moulding and assist in
removing the moulding. If the plastic is still too soft some distortion may occur. In this
instance then reverse the pump to apply vacuum and wait till plastic has cooled
sufficiently.
!
Finally, lower the table and release the material clamps to remove the finished
moulding.
