In addition to fixed center design, multi-port spiral flow, and gum space adjustment, The Bullet™ Extrusion Head features no fastening hardware for easy cleaning. Absence of fastening hardware also eliminates leaking, as does taper body and deflector. Product allows quick tooling changes, as tips remove from back and die removes from front of unit. Supplied with vacuum chamber and kit for assembly and disassembly, extrusion head is suitable for both high- and low-volume applications.
