HF extrusion heads offer a universal flow channel technology with our unique hammerhead locking system to ensure fast & safe changing of profiles in combination with a high degree of operational reliability and precision. Co-Extrusion heads are available with head openings of MW 500 mm and MW 800 mm. The Duplex is also available in MW 650. The available setup extends up to five extruders:
HF offers modular tooling for flexible head openings, fast profile changes and reduced changeover times. Basic flow channels are already milled into the large movable parts of the extrusion head. Lightweight insert pieces allow quick and easy change ensuring full flexibility, for example from sidewall to tread or single to dual cavity extrusion. The individual flow channel re-configuration delivers the following benefits:
Special emphasis is placed on the design of the flow channels in the extrusion head. On the one hand, the smoothest possible transition from the circular cross section at the extruder outlet to the rectangular, flat geometry of the profile in the area of the die is desired. On the other hand, care is taken that in the flow channels pressure; temperature and speed of the mixture over the entire flow cross-section are as identical as possible. Consequently, HF applies state-of-the-art software to calculate three-dimensional flows in order to achieve optimal results.
