Freezing clamping technology
The ice tray trapped into the freezer compartment or frost sticking to our windshield on winter morning, these are xamples of the strong adhesive power of ice. Using this natural property we have developed and designed a highly effective clamping system: GF series icing plates*.
Plate cooling is achieved by means of a compressed-air heat exchanger*. A pneumatic thermal control system* allows to obtain a constant temperature and to save on compressed air by acting on the thermal inertia of the icing plate. Originally designed to meet the needs of space industry workshops, icing plates have since become a necessity in all fields involving the manufacture of delicate parts (medical, electronics, watchmaking, jewelry.).
Features:
- Any material can be clamped: metal, plastic, graphite, ceramics, honeycomb, fabric, neoprene, rubber .
- Parts of any shape are firmly held in place (no more specific assemblies)
- Stress-free clamping and unclamping, therefore no risk of distortion or breakage
- High fastening power: 15 kg/cm2 on metal (by comparison, 12 kg/cm2 for magnetization, 1kg/cm2 for vacuum)
- Fast, freezes and thaws in seconds
- Release of the parts leaves no residue
- Increased rigidity for many materials (plastics, raw ceramics, neoprene,…) and improved surface condition
- Longer tool life
- Easy to set up, plates are compact and monoblock
- Operates simply with compressed air**
Vacuum clamping for metalworking machines
The Vacuum-Plate is particularly suitable for process-safe clamping of large, flat metal workpieces with smooth bottom surfaces on CNC machining centers and guarantees very short set-up times..
Features:
- The Vacuum clamping system Vacuum-Plate for distortion free clamping of large flat workpieces

- High precision (height tolerance ± 0.02mm)
- Short set-up times; easy to handle
- Mechanical stops as positioning aids and to accommodate additional horizontal forces
- High degree of flexibility due to modular design
- Simple machining of apertures by combining the Vacuum-Plate with grid table suction blocks from Spreitzer
- High horizontal holding fores with optional friction pads (up to 30% higher)
- Friction pads activated and deactivated automatically when the Vacuum is switched on and off
