How
does it work?
The
process of vacuum pressing is very simple. A vacuum is created
in a vacuum bag or frame press by a vacuum pump, thus Atmospheric
pressure is used as the working force. Atmospheric pressure is the actual weight
of the air around us, about 14.7 pounds per square inch (PSI),
this equates to 1 ton per square foot of working pressure! The complete system
includes a vacuum bag or vacuum frame press that is connected with a hose to a powerful,
vacuum pump- that's all. To use the system place your glue-coated
panel and veneers inside the press, turn on the pump.
Within seconds your work will be perfectly vacuum pressed,
without any hassle at all.
Your
veneer will be pressed smooth and wrinkle-free every time. The
uniform pressure eliminates shifting veneers and air pockets,
creating perfectly smooth panels and bent laminations providing
consistently predictable results.
Air
is drawn out of the wood's cells, allowing deep glue penetration.
This creates thin, even glue lines and an excellent bond with
minimum squeeze out. Pressing cycles are reduced to 30-45 minutes
when using PVA glue and working at room temperature or 5-10 minutes
if the press is heated.
