New Extrusion Head for Quick-Change Tooling

The absence of fastening hardware eliminates leaking, as does the taper body and deflector design pioneered by Guill.

The Bullet II is absent of hardware, i.e. nuts and bolts, so disassembly, cleaning, and restart are made easier.

Guill Tool

Guill Tool (West Warwick, RI) introduced The Bullet in 2015, a new extrusion head with fixed center design, multi-port spiral flow design, and gum space adjustment, plus the added feature of no fastening hardware, so cleaning and restart are easier and faster.  Today, the company has announced the next generation of this 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 fastening hardware eliminates leaking, as does the taper body and deflector design pioneered by Guill. Additionally, the new patent pending CAM LOCK deflector retaining system offers these additional benefits to extruders and machine builders:

  • It only takes ½-turn of the Cam Lock to remove and install the deflector and tip.
  • No fastening hardware required.
  • Fast tool changes, threaded retaining 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 operating costs.

High- and low-volume applications are suitable for this head. A family of crosshead designs is available and users can specify the caliber, or the max 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, proper cleaning and restart.
