Dassnagar  has the expertise to design and manufacture all categories of  Collapsible type hydraulic grip Mandrels to be mounted on Uncoilers or Recoilers. The average life of our mandrel is 5 years.

We also undertake mandrel repairing jobs where we remove the worn or damaged mandrel from your equipment, take them to our shop for dis-assembly, inspection, repair, and if necessary,  re-engineer and upgrade them before re-assembly. Then we will re-install the mandrel in your equipment.

We repair grippers, bronze overlay the wedges and bearing pads, re-turn and carbide coat segment O.D.'s and cloverleaf them to minimize coil breaks.

We also repair, straighten and re-true mandrel spindles and quills.

We repair all makes, models and type of  uncoiler and recoiler mandrels, including cantilever, dual stub, step down and cone shaped, either caliper or wedge type expansion.
