Extrusion head with no hardware, for easy cleaning
Guill Tool's The Bullet® is an extrusion head with fixed-centre design, multi-port spiral flow design and gum space adjustment. It features no fastening hardware, so cleaning and restart are quick and easy. The company recently began offering the next generation of this 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. It only takes half a turn of the Cam Lock to remove and install the deflector and tip; no fastening hardware is required. There is a threaded retaining ring for the die and threaded tip retainer, and tooling retainers also provide gum space adjustment.
High- and low-volume applications are suitable for this head and are accommodated with the simple changing of just one component. Various crosshead designs are available and users can specify the
calibre — 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. The overall unit design enables faster disassembly, cleaning and restart.
