Technical Data
MULTIMAT Membrane Pressing Table
1 vacuum pump TF 40
vacuum pressure: 900 mb (t/m²)
Extendable Control Panel:
The controls available vary in accordance with different MULTIMAT models
Vacuum Membrane:
Construction: vacuum-sealed inside the membrane frame
Material: highly elastic, robust, and durable silicon membrane
Manual stress: 18 N/mm², 700 % elongation at break point, highly wear-resistant
Thermal stress: -40 °C to maximal +220 °C
Heating cover:
1 aluminum cover (entire surface is insulated), attached to the membrane frame with swivels, includes interior lighting
1 circulating air heating system (electrical connection: 10 KW, 400 V, 50/60 Hz)
1 thermostat, seamlessly adjustable between 0 and 140 °C
2 pressure springs
Additional equipment: Semi-automatic process control unit
The semi-automatic process control unit automatically initiates the vacuum pressing cycle once the selected pre-heating temperature is reached. Once the automatic process is initiated, the unit warms up to reach the selected temperature. After completion of this process, an acoustic signal announces the commencement of the automatic vacuum pressing cycle. The pressing cycle is ended with a manual switch. Closing and opening of the heating cover also has to be done manually. Likewise, the pneumatic lifting and lowering of the membrane frame is controlled manually (by pressing the corresponding control lever).
Additional equipment: Fully automatic process control unit
Optional settings: - Adjusting the pre-heating temperature
- Adjusting the heating period
- Adjusting duration of the vacuum pressing cycle
- Adjusting duration of the vacuum cooling cycle
The fully automatic process control unit enables you to adjust the pre-heating temperature, the duration of the vacuum pressing cycle, and the duration of the vacuum cooling cycle.
Once the automatic process is initiated, the selected pre-heating time starts to count-down. After reaching the selected temperature, the vacuum pressing cycle is initiated automatically. Once the pressing cycle is completed, the heating cover is lifted automatically, so that the cooling cycle can commence. When the cooling cycle is completed, the vacuum pump is automatically turned off.
Closing of the heating cover is controlled by pushing the corresponding button. It opens automatically after the pressing cycle is completed. The pneumatic lifting and lowering of the membrane frame is controlled manually through the touch of a button.
The fully automatic process control unit makes use of a SPS control system with and includes an operating display.
For custom application areas, MULTIMAT units can be equipped with special control units.
Production capacity:
3D-foil lamination: approximately 5 – 10 minutes, depending on number of inserted work pieces (requires heating cover)
Vacuum layer-gluing: 15 minutes to 6 hours, depending on shape of the work piece and material/glue used
Vacuum form-veneering: between 10 and 30 minutes, depending on shape and type of glue used
(if the heating cover is used, the pressing cycle for layer-gluing can be shortened by up to 80%, the pressing cycle for form-veneering by up to 60%)
