#85756 VACUUM FORMING MACHINE – STEP-BY-STEP INSTRUCTIONS FOR USE
Unpack the machine and place it on
your workbench in the position
shown. Notice that the orange handle
is in the horizontal position and the
two control switches on the front of
the machine are in the OFF position.
Plug the line cord into a wall outlet.
Note: The heater draws a lot of
current, so try to avoid using an
extension cord that could overheat.
1
Use diagonal cutters or a knife to
snip the cable tie holding the frame
parts during shipment.
2
Rotate the heater all the way to the
left to get it out of the way for the
next few steps.
3
Optional – Pour the metal beads into
the vacuum chamber. The beads act
as a way to support patterns with
irregular bottoms. If your pattern has
a smooth bottom, you may elect to
skip this step.
4
Use your fingers to spread out the
metal beads evenly in the vacuum
chamber.
5
Place your pattern in the chamber.
6
Use your fingers to push the metal
beads around the bottom perimeter
of your pattern. This will keep the
plastic from wrapping around the
pattern, making it difficult to remove
later in the process.
7
Swing up the top half of the frame.
It should stay in place.
8
Insert a 5” x 5” sheet of plastic into
the recess in the bottom frame.
Note: Not for use
with polycarbonate.
9
Swing down the top frame and pull
the latch knob over the tongue to
lock it in place. This will clamp the
two frames together and hold the
plastic ready for heating and forming.
10
Push the orange handle down to
latch the metal frame in the UP
position.
11
Turn on the heater.
12
The basic procedure:
A pattern is placed in the vacuum chamber. A sheet of thin plastic is suspended above it in a
metal frame. A heater located above the plastic causes it to soften, at which time the vacuum is turned on and the plastic is
moved downward over the pattern. Vacuum draws the soft plastic around the pattern and makes a copy of the pattern shape.
When the plastic cools, it is removed from the chamber and excess trimmed away.
