 The double twist stranding machine delivers high-speed compact stranding for power cables, communication conductors, and data wires. The structure generates two effective twists per rotation, enabling greater production output with reduced energy consumption. Cable factories adopt this system to raise conductor density, stabilize pitch quality, and handle multiple wire configurations across medium and high-volume production lines. How the Double Twist Mechanism Works The double twist machine transfers motion through a rotating bow and cradle system. The configuration forms two twists for each full revolution of the rotor. The geometry shortens the pitch, increases stability across different wire diameters, and controls lay consistency under continuous high-speed operation. The design limits vibration through symmetrical mass distribution inside the rotor frame. Core Components that Shape Performance Rotor System The rotor determines maximum speed and pitch range. The Dosing C...

In modern cable manufacturing, the wire extrusion machine represents the core of every insulation and sheathing process. Within this system, the extrusion crosshead functions as the critical precision interface that determines material flow, insulation uniformity, and production speed. This article revisits crosshead design within the context of complete wire extrusion systems, exploring how advances in flow geometry, thermal control, and modular construction redefine both process efficiency and cable quality for next-generation production lines. 1. Introduction: The Wire Extrusion Machine as a System The wire extrusion machine is more than a collection of mechanical parts—it’s an integrated ecosystem that converts polymer and conductor into a finished, high-performance cable. At its core lies the extrusion crosshead , the element that distributes molten material evenly around the conductor. When crosshead performance falls short, the entire extrusion line suffers, manifesting i...
