Extrusion International 2-2018

20 Extrusion International 2/2018 EXTRUSION TOOLING “THE BULLET II” Extrusion Head Guill Tool introduced The Bullet ® in 2015, a new extrusion head with fixed center design, multi-port spi- ral flow design and gum space ad- justment, plus the added feature of no fastening hardware, so cleaning and restart are easier and faster than any conventional head on the mar- ket currently, according to company sources. The company announces the next generation of this unique and patented tool, The Bullet II. 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 fas- tening hardware eliminates leaking, as does the taper body and deflector design pioneered by Guill. Addition- ally, the new patent pending CAM LOCK ® deflector retaining system of- fers these additional benefits to ex- truders and machine builders: • It only takes ½ turn of the Cam Lock ® to remove and install the De- flector and Tip • No fastening hardware required • Fast tool changes, threaded retain- ing ring for the die and threaded tip retainer • Dies are removed from the front and tips from the rear • Tooling retainers also provide gum space adjustment • Hassle free air / vacuum connections • Simplified cleaning • Reduces downtime and lowers op- erating costs High- and low-volume applications are suitable for this head and are accommodated with the simple, easy changing of just one compo- nent. A family of crosshead designs is available and users can specify the “caliber”, that is, the max. die ID. A vacuum chamber and kit for as- sembly and disassembly are includ- ed with the unit. Optional keyed tooling capability offers machine designers and end users quick ori- entation, so the overall unit design enables faster disassembly, proper cleaning and restart, allowing the line to become more profitable, more quickly.
