The atmospheric pressure is around 1 kg / cm2 (almost 9 tonnes per m²).
The vacuum is a space that contains less air or gas than atmospheric pressure.
With the help of a pump, retreat the air on one side of the wood, thus creating a vacuum. The pressure pushes the wood to the other side.
THE PUMP
It is a dry blade pump (Becker or Busch) 8m3 / h.
It does not require maintenance or replacement parts.
It is very reliable and less expensive.
It is possible to increase its performance while keeping the basic equipment.
VACUUM BAGS
They are made of polyurethane, an industrial type material, and have many advantages:
Flexibility
Strength - does not tear
Smooth surface - makes it easy to place work pieces and clean up excess glue
Price equivalent to that of vinyl bags (lower quality) offered by our competitors
COLLAGE - GLUING
The type of glue used anywhere since it is the force exerted (several tonnes) that holds the two pieces together.
Drying does not require air: when pressed, the water contained in the glue migrates into the wood which is emptied of its air. The support will dry over time in ambient air.
