Operating Techniques Formech FM660
Heater timer
The FM660 is fitted with a three digit LED count down heater timer intended to assist the production of
a large number of similar mouldings.
The timer function is enabled when a number is shown in the display and disabled when the display
shows ’Zero’. The timing ‘seconds’ value is adjusted by touching the ‘
’ or ‘
’ buttons either side of the
three digit display. The adjustment count will speed up if you hold your finger on the up/down
adjustment buttons.
The timer countdown is triggered when the heater reaches its forward position and visibly counts down
the seconds to give a useful indication of the heat time remaining.
An audible bleep is given when the countdown is complete and the display resets to the pre-set time.
The buzzer indicates that the heating cycle is complete and the heater may be pushed back.
Pushing the heater partially backward or forward during the heating cycle will not interrupt the
countdown.
Bubble moulding
With the FM660/FM660PT it is possible to produce bubble mouldings without using a tool. To form a
bubble the plastic sheet should be heated with the drape table in the lowered position. When the plastic
sheet has heated right through, push back the heater, touch the pre-stretch button and hold. If you are
using the FM660 without an air supply use the release button to blow. The plastic will start to inflate.
