TECHNOPOLYMERS - HIGH PERFORMANCE COMPOUNDS
HP-T series are heads dedicated to process Standard compounds, engineered compound, techno-polymer and high performance compounds.
The head as well as each single component, is made by special hardened steel with special additional treatment for highest wear resistance and highest smoothness.
The head can achieve working temperature higher than 400 °C.
The distance between tip and die is regulated by axial die movement through scaled die nut.
HP-T is compact and round head for low residence time and excellent flow distribution.
The melt flow distributor design guarantees the highest product concentricity, without stagnation and easiest extraction.
The Head and the flow channels and flow sections are properly designed to get the highest quality and excellent cable surface reducing the shear rate and shear stress.
The head is equipped with high quality and efficient heating system for accurate thermoregulation.
Accurate and efficient die heating.
The Head assures:
- Low shear
- No Distributor locking
- No material overheating
- No stagnation
- Easier assembling and dis-assembling
- No plastic sticking on the heaters
- Accurate and efficient heating system
CENTERING
- Fixed Centring
- Manual Centring from front or “fine adjustment” from rear (Optional)
GUM SPACE
The gum space can be regulated by:
- Axial die movement from front
The die nut is scaled for proper die positioning.
COMPOUNDS PROCESSED
Most of Technopolymers and high performance compounds, such as:
PEEK – PEK – PEI – PA – PEI – PC, PSU,…
HEATING
