General Arrangement
Machine Arrangement (continuation)
5. Touch screen HMI
The machine is operated though this HMI providing easy use though intuitive graphical software to operate
the machine and adjust the settings.
6. Vacuum Gauge
This is situated on the top right hand side 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 22”Hg / -750mbar of
vacuum.
7. Material Clamps
These clamps lock the Clamp Frame firmly down. After placing the plastic under the clamp frame the
material clamp levers are pulled up to lock in place. Adjust the black nuts on the clamps to suit the thickness
of the clamped plastic material or when a reducing window is fitted. Adjustment may only be carried out
while not under pressure. The rear of the clamp frame is spring loaded and self-adjusting.
8. Clamp frame
This holds the plastic material in position during the forming and release processes.
9. Table Lever
When pulled towards you the table will rise to the upper limit. A further application of pressure will lock the
table in this position. During forming the table complete with mould is lifted into the hot plastic and locked
in place to ensure a good vacuum seal. At the end of the cycle the table is returned to the lower position by
pushing the handle back and away.
NOTE: A mechanical interlock designed to prevent a mould being raised into the heating elements stops the
table being raised unless the heater box is fully back
10. Heater Box
This carries the heating elements and is drawn forward by manually pulling the centrally mounted handle.
The heating zone control system has built in safety features:
The manual mode ‘count up’ timer has a limit of 300 seconds after which the heater will turn off all power
to the heating elements if the heater is still forwards.
When the timed program is loaded, 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.
11. Safety Labelling
The heater and heater guard will have hot surfaces. Take note of the labelling in these areas.
+ Air pressure outlet (see footprint on page 10 for location)
When the vacuum pump is running, the pressure is diverted to this outlet. This can be used to supply or run
other equipment when not being used for vacuum forming. Do not block this outlet or attempt to connect
air supply. THIS MACHINE DOES NOT REQUIRE AIR SUPPLY.
