Generally speaking,Increasing restoring force of casing centralizer is by high grade spring steel and then doing some heat treatment,but in order to get higher restoring force and lower starting force,we redesign our bow which is like Chinese shuttle,the central part of centralizer bow combines higher restoring force.
