Balance weight and manufacturing method for the same |
(57) The invention relates to a balance weight and a manufacturing method for the same
using commercially available iron ore concentrate and compaction technology. The proposed
solution, according to the invention is that the iron ore concentrate is compacted
or a coupling matrice is added to it and then they are exposed to pressure and temperature
depending on the specific coupling matrice chosen. Another method is using fluidized
bath coating or electrostatic or electrokinetic coating of material on the base of
polyethylene, high density polyethylene, low density polyethylene or another type
of thermoplastic polyolefin, thus encapsulating the balance weight. These different
production methods can be combined. The balance weight is used primarily for automatic
washing machines, but also for machines and equipment, where damping unwanted vibrations
or displacements of gravity is needed.
