<p>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.</p> |
