Bag Presses are used for creating curved laminated surfaces and panels for construction and surface finish. Our product range has developed and grown with the experience gained in real workshops. We take a commercial view in all the advice we give and prefer to offer recommendations based on this experience rather than regurgitating ‘accepted wisdom’.
For example, we press and veneer nearly all non-structural panels using a high grade D3 PVA rather than a UF or Resorcinol resin. PVAs have improved dramatically in recent years to the degree that they are the ideal adhesives for vast majority of vacuum press requirements. The simplest type of vacuum press uses a sealable bag and some form of vacuum pump. By placing materials in the bag, sealing it and then sucking out most of the air, a pressure differential is created between the reduced pressure inside the bag and atmosphere on the outside. It is this pressure differential that is used in vacuum pressing. Bagpress has also pioneered the use of extruded polystyrene as the ideal material for vacuum press formers - we offer a CNC hot wire cut mould making service to take the pain out of your production - email us your drawings.
