ISOLOC sprung foundations are suitable for all machines and plants.

A sprung foundation insulation is in the furthermost sense every vibration insulation that is not directly under the machine, but under the machine foundation. Such a machine foundation is mostly sunk in the floor in a foundation well (underground), but it can also be above ground with smaller dimensions.


Purpose of a sprung foundation is mostly:

Improvement of the dynamic behaviour of a machine
By the additional mass of the concrete bloc and the ISOLOC vibration insulation elements, improvements of the dynamic behaviour are achieved with natural frequencies remaining the same compared to a directly isolated machine: smaller amplitudes, the connected elements are used less (tearing off), additional hardening of the machine, smaller mass forces act on the components of the machine (longer life of the bearings).

Increasement of the stability and torsion rigidity of a machine
Certain machines/systems require the installation on a foundation for hardening if a vibration insulation is provided. For this reason, the elastic vibration insulation elements have to be placed under the additional mass. By the foundation bloc also not torsion rigid machines with very elastic, low-frequent ISOLOC vibration insulation packs can be installed and isolated from vibrations.

Lower natural mounting frequency of the vibration insulation
Due to the increasement of the weight by the (elastically mounted) additional mass and therefore the lower natural mounting frequency with the same number of vibration insulation pads a higher insulation grade is possible.

As protection against emissions
e. g. for presses, punches, air hammers, printing machines, ball mills, forging machines, testing stands, turbines, broaching machines and many others.

As protection against immissions
e. g. for measuring machines, grinding machines, precision fine-finishing machines, microscopes as well as all machines and systems sensitive to vibrations with the highest demand to precision.

Source insulation protection against emissions	Receiver insulation protection against immissions

Precision fine-finishing machines beside presses.
Is this possible?
In order to achieve the required surfaces and tolerances in this case either a source insulation of the press or a receiver insulation of the precision fine-finishing machine is indispensable. The necessary very low tuning of the insulation elements requires therefore a sprung foundation.
