Continuous Vulcanization (CV) Dry Cure Lines

Supermac’s CCV line are meant to run long continuous production schedules taking care of frictional heat and pressure to deliver uniform production. The incorporation of high torque motor and drives provides Customer with wide range of torques required to extrude various products, since the system is compact it is easy to couple the system directly on the machines & eliminates the requirement of various speed changing Gear Boxes.

The line is equipped with driven Pay off & Accumulator, so that the changes over of reels can be done without stopping the line. The entry Capstan runs in synchronization so that the cable is controlled optimally & line runs without any jerk. The online X-Ray device checks and displays the concentricity & thickness of all three layers to operator on the screen during the running of the line.

The curing of cable is done though nitrogen gas in the catenary tube online. Once the heating part of curing is done, then starts the cooling of cable with in the tube. The cable comes out cooled & cured out of end-seal portion of the curing tube. The exit Caterpillar is provided with enough pulling force to handle the cable tension to maintain the Catenary Sag in the tube.

Supermac offers a new online service support system to Customer where in the PLC software & program can be handled from Supermac offsite, giving customer fast support in the hour of need. The Triple Extrusion Cross Head is a state of art product of Supermac product profile; it incorporates the melt distribution of different profile, shape & depth for all three layers. The system is oil/water heated from inside, which uniformly heats all the zone of the Cross Head.
