Abstract

An extrusion ring has a base from which multiple segmented rows of rings integrally extend. Gaps in one row are offset from the adjacent row to cover any gaps. The rows gain strength from a common base that also prevents relative rotation among the rows. The overlapping rings are additively manufactured with breakable restraints in some or all the gaps that fail during the setting such as in shear. Faster running in rates can be realized as each ring row has hoop strength due to the ties in the gap or gaps that are incorporated into the additive manufacturing process to make the assembly. Residual stresses in each ring from the additive manufacturing process are resisted from the ties in the gaps. Ties between overlapping rows are also contemplated.
