GUILL Tool introduced The Bullet® in
2015, an 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 now launched 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.
