Coil Processing Equipment

Overview

Dassnagar  designs and builds Coil processing equipment that allow you to enhance productivity with superior product quality, that too at an attractive price.

We have the expertise to design and manufacture all categories of  Uncoiler and Recoiler mandrels. These mandrels can easily be retrofitted to existing cut-to-length, slitting, and other special purpose coil processing lines.

We repair mandrels of all makes, models and types - caliper or wedge type expansion. This may include repairing of  grippers, bronze overlay the wedges and bearing pads, re-turn and carbide coat segment O.D.'s and cloverleaf them to minimize coil breaks.

Our operator friendly, easy-to-maintain coil handling equipment offers you un-paralled reliablity, rugged durability, precision operation, and advanced technology. Special purpose equipment are also available on request.
