Pushing the limits with the RX 25T for foamed RF Cable from Rosendahl

The oil-tempered Rosendahl Crosshead RX 25T

The Rosendahl Crosshead RX 25T for foamed RF Cable cores is designed to manufacture the complete RF Cable range from 1/4" SF to 2 1/4" F.

Its basic design comprises an oil heated crosshead with skin application which is equipped with an optimized temperature control to cover expansion rates of up to 86%. Two heating/cooling zones on the crosshead, one for the main body, the second for the die holder provide perfect temperature control and even temperature distribution of the polymer gas melt.

Full natural balancing minimizes the shear rates and provides smooth melt flow for perfect roundness, concentricity and mechanical stability. Superior manifold technology enables small formed cells and a very homogenous cell distribution at this high foaming degree.

Temperature control, shear stress, pressure drop and flow speed optimization in the crosshead are significant factors for achieving higher foam expansion rates on the final cable, up to 86%. This new design enables RF cable manufacturers to surpass limitations currently experienced with standard equipment.

The RX 25T Foam Crosshead allows increases in productivity and cable performance – promising a fast payback on investment.
