Abstract:
A process for the manufacture of thin-walled elasto-porous elements in the form of bushings in metal-rubber material (MR), comprises the steps of: obtaining wire fragments in the form of spirals having a lead equal to the spiral diameter, forming a flat blank from said spiral segments; pressing the blank into a roll; placing the roll into a mold; placing some elastic medium inside said roll; and pressing the roll in several passes by axial compression together with the elastic medium elements transforming the axial compression into radial pressure on the roll to be compressed.
