GUILL Tool introduced The Bullet® in 2015, a new extrusion
head with fixed centre 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 than any conventional head on the market currently,
according to company sources. The company has announced
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 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 a half 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
and are accommodated with the simple, easy changing
of just one component. A family 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, proper
cleaning and restart, allowing the line to become more
profitable, more quickly.
