In addition to the variants described below Unitek offers a number of heads for additional applications, e.g. for extreme thin wall single or multi-layer extrusion coating of pipes, heads for medical extrusion as well as the manufacturing of fuses. Heads with heart curve and hole distribution: For low-output and low-viscosity meaterials SL = for single layer extrusion SK = for additional co-extrusion of skin ST = for additional co-extrusion of stripe Dual layer heads with intermediate tool System 2IT: These heads use an additional extrusion tool between standard tpye wire guide and die for a separated extrusion of two identical or two different materials in one head such as bedding plus sheating compound. DL = for dual layer extrusion SC = fixed centered MC = manually centered S = for additional extrusion of stripe DLV = for additional extrusion of skin SZ crossheads: Extremely compact heads for SZ-stranding-tandem extrusion of flexible cores. SL = for single layer extrusion DL = for dual layer extrusion DL crossheads: These heads are designed for the co-extrusion of polymers with similar melt temperatures Crossheads with thermal barrier: These heads are available for co-extrusion with melt temperature differences of up to 100°C (212°F). Liquid medium temperature controlled crossheads: Crossheads for rubber of cross-linked material extrusion. Types & Dimensions: Product Folder:   Click to enlarge Download PDF |
