Miniblok springs
    Mini block coil springs are characterised by variable diameter of particular coils. This system of design has such a result that during the application of load to the spring its coils successively set on resistance plain. Owing to that, it is possible to attain a particularly low spring under load, which does not limit trunk volume.
    Moreover the miniblock spring is of progressive characteristic, that is spring rate increases with the increase of load. This is advantageous for human physiology from the point of view of vehicle vibration.
    The production of that type of springs is more highly advanced technically regarding both bar material preparation and coiling process as well as heat treatment process.
