Abstract: Conventionally co-axial cable is made in a continuous extrusion machine by continuously extruding an aluminum tubular cladding (1) through an annular die and simultaneously continuously introducing a core (4), comprised of a conductive wire surrounded by insulation, through an bore in a mandrel (3). A gap is inevitably present between the outer surface of the core (4) and the tubular cladding (1). To eliminate the gap it is necessary to reduce the diameter of the tubular cladding by swaging or drawing. The present invention disposes of the &wagging or drawing step by compacting the insulation of the core before introduction to the mandrel (3). The insulation then gradually expands to recover its original diameter and fill the cladding which has been extruded to its final diameter.
