The Bullet from Guill Tool, W. Warwick, R.I., is a new extrusion head with fixed-center, multi-port, spiral-flow design and gum space adjustment. It requires no fastening hardware, so cleaning and restart are reportedly easier and faster than any conventional head on the market. The Bullet’s tips remove from the back and the die removes from the front of the unit to facilitate changes. The absence of fastening hardware eliminates leaking, as does the taper body and deflector design.
The head can be used on high- and low-volume applications, accommodated by easy changing of just one component. A family of crosshead designs is available, and processors can specify the maximum die ID. A vacuum chamber and kit for assembly and disassembly are included with the unit. Optional keyed tooling offers machine designers and end users quick orientation.
