Easy-clean extrusion head with quick-change tooling and deflector retaining system

Tooling retainers also provide gum space adjustment. High- and low-volume applications are both suitable for this head and are accommodated with the simple changing of just one component. A range of crosshead designs is available and users can specify the ‘calibre’, ie the maximum die ID. A vacuum chamber and kit for assembly and disassembly are included with the unit. Optional keyed tooling capability offers machine designers and end-users quick orientation, so the overall unit design enables faster disassembly and proper cleaning.

GUILL Tool introduced The Bullet ® in 2015 – an extrusion head with fixed-centre design, multi-port spiral flow design and gum space adjustment, with the added feature of no fastening hardware, making cleaning and restart easier and faster. The company has now announced the next generation of the patented tool. The Bullet II allows quick tooling changes, as the tips remove from the back and the die removes from the front of the unit. The absence of fastening hardware eliminates leaking, as does the taper body and deflector design. The new patent-pending Cam Lock ® deflector retaining system offers additional benefits to extruders and machine builders. Only half a turn of the Cam Lock is required to remove

and install the deflector and tip, and no fastening hardware is necessary. It features a threaded retaining ring for the die and threaded tip retainer. ❍ The Bullet II’s absence of fastening hardware simplifies disassembly, cleaning and restart
