Enhanced tube shoulder appearance

• Excellent aesthetics, reduce flow lines on coloured shoulders
• Perfect edge and welding for round and oval shoulders
• Cleaner and smaller orifices now possible
• No air trapped on shoulder head
• No crooked shoulder head

Improved economics

• Faster and less frequent tooling change-overs
• Improved process stability leading to higher productivity
• Reduced tooling needs through standardization
• Up to 60 % lower investment on dosing nozzles
• Faster colour change over

Fed with a high-performance extruder system, the volumetric dosing ensures a precise and repeatable melt dose, while the helical grooves remove flow-lines, improve colour dispersion and melt homogeneity. In addition, the spiral flow technology improves optical characteristics, allows faster colour changes and eliminates material memory.
