Dampers and springs
We customize the properties of our PUR dampers and spring elements from springy (energy retaining) or damping (energy absorbing) especially for you
Properties
- Polyurethane plastics can be formulated as to exhibit either dampening (energy-absorbing) or springy (energy-conserving) characteristics
- Compact (non-foamed) polyurethane elastomers show a constant volume because of their viscoelastic behaviour and can be deformed up to 30% in continuous operation
- Foamed polyurethane elastomers are compressible and exhibit no lateral strain up to a deformation of 30% and can be deformed up to 80% in continuous operation
- Springs and dampers made from polyurethane elastomers are resistant to humidity and corrosion in comparison to metals
Application
- Spring elements are used to conserve energy (hold-down devices and ejectors in punching tools)
- Swinging elements in screening machines, rubber-metal elements, form elements and cushions, pickers…)
- Damping elements to absorb energy (end stops, impact buffers, bump stops…)
Available at asma
- Customer specific components according to drawings and models
- With dampers and springs, our customers can choose between compact polyurethane elastomers in a hardness range from 30 to 95 Shore A and polyurethane elastomers with a density of 450-900 kg/m3
- Dampers and springs can:
- be produced using semi-finished goods or moulds
- be produced adhering to metals
- receive force progression by a geometric mould design
