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.
