Machine arrangement (continuation)
The back zone 3 also tends to stay hotter than the front zone 4 because the rear of the machine is heated by
the heater when it is not heating plastic. A key feature of quartz heating is the response time for changing
to different power levels. The zone controllers are highly accurate and keep the element power level within
1% of the requested setting. Beginners to vacuum forming will quickly become accustomed to setting the
zone controls for best results.
15. Digital Timer.
When producing a quantity of mouldings using the same mould and plastic the heating time will be nearly
constant for each one. In this case the timer can be used. Record the heating time for the fi rst moulding
then set the timer (in seconds) using the UP / DOWN buttons the buttons. When the heater is pulled
forward the timer counts down from the set time and sounds a buzzer when zero is reached. The heater is
then pushed back. The set time is stored until it is altered. If you don’t want to use the timer, set the time to
zero.
The timer has built in safety features. If the heater is forward for more than 2 minutes after the timer has
completed the set time the heater will switch to the standby setting. If the heater is not returned to the
standby position after a further 2 minutes then the heater will turn off all power to the heating elements.
16. Vacuum Gauge.
This is situated on the top RHS of the front panel and gives indication of the vacuum level achieved at the
table mould area during moulding. It is usual to expect approx 25”Hg / -750mbar of vacuum. If such levels
are not achieved check your mould / table confi guration & clamp / plastic sealing.
Reducing Windows
Reducing windows allow the use of smaller sheet material for smaller mouldings. Reducing windows allow
for better sheet utilisation. To fi t the reducing window:
1. Lift the clamp frame.
2. Place the lower reducing window on to the top frame aperture so that the corner locating screws are
aligned.
