Wemhoener Model No.: Universal 2000 Variopress (UM# MS 29198)
NEW Membrane Press - YEAR 2006 -
NEW Wemhöner Variopress, Model Universal 2000
(1500 x 2800)
Located in No. Carolina.
The most efficient lamination of single-sided, pre-profiled panels with veneer, thermal-plastic foil or other suitable flexible laminating material.
The press system, a single daylight down stroke, consisting of steel frames bolted together to form a closed unit. Each frame is manufactured out of a single piece
of steel. Top platen is electronically heated.
System Capacity
Mechanical Time
Time for opening, closing, infeed, outfeed, pressure build-up and reduction, not including press time is approx. 30 seconds.
Press Time
The pressing time (or curing time) depends on the type of laminating material, the press temperature, the adhesive and similar factors. It is impossible to provide a general, binding estimate with regards to the press time. For standard thermoplastic foils, press time will vary from approximately 90 seconds to 120 seconds. Press time for veneer 0.6 mm thick is approximately 180 seconds to 240 seconds, depending on veneer type.
Pressing Programs
Single-Sided Lamination (Top) or Pre-Profiled Substrates
A. thermoplastic foils without membrane for preheating as well as
forming, pressing B. veneer, using a membrane for forming, pressing
C. thermoplastic foils using a membrane for the preheating of the foil
and for forming, pressing
D. thermoplastic foils using a membrane for the preheating foils and for forming, pressing of the foils without membrane (simultaneous pressure)
Material for Foil Lamination
Substrates
MDF or particleboard as well as other suitable substrate material. The panel profiling has to be matched to the relative laminating material and procedure.
Laminating Material
• standard thermoplastic foils (PVC, PET, ABS, PP, etc.)
• materials to be suitable for the applicable pressing procedure
• delivery in roll material (width 56-9/32”)
• additional width and length dimensions are possible with additional equipment
• standard veneers as fixed formats with appropriate jointing
Glue Systems
• PUR dispersion adhesives added with cross linking agent for thermoplastic foils
• standard UF glue with hardener and filler or PVAc glue for veneer

• tray rotation is clockwise
Infrared Control Sensor
• used to monitor membrane temperature
• helps assure correct membrane temperature before beginning the pressing process and to avoid faulty pressings
One Multi-functioning Frame (Wemhöner Patent)
• to be fitted and dismantled quickly when changing the
pressing program
• recommended for the pressing of thermoplastic foils
Advantages:
• two (2) further pressing programs are possible
Pressing Programs
• thermoplastic foils with membrane
• thermoplastic foils with simultaneous pressure
Further advantages:
• re-cooling of the thermoplastic foil after the pressing process to avoid
memory effect
• cooling down of the glue joint
• soft separation of the membrane from the thermoplastic foil by means
of blow-in device
• no change-over time for pressing program with simultaneous pressure
One (1) Silicone Membrane included
• 3 mm (1/8”) thick
• necessary for 3D pressing of thermoplastic vinyl films with membrane and thermoplastic vinyl films with simultaneous pressure
Automatic Dispensing and Cutting of Vinyl from Above Magazine
• to equip the Calendar and Cutting station with length selection controls
• motorized dispensing and automated cutting of vinyl
Automated foil Lay-up Device
• lay-up of foil sheet onto tray with moving clamp system
