Special Applications

Besides all standard crossheads Unitek offers a large variety of crossheads for special applications allowing for the extrusion of complex materials and complex products.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 meaterial
  • 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.
