Extrusion 6-2021

52 kompakt Extrusion 6/2021 faster than any conventional head on the market currently, according to company sources. The company announces the next generation of this unique and pa- tented 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 pioneer- ed by Guill. Additionally, the new patent n Guill Tool, a global leader in extrusion tooling technology, announced a new design for its high-production rotary models, both inline and crosshead style. A 2X increase in speed, with models run- ning to 1000 RPM depending on the ap- plication, are now available in the Guill line of patented rotating tip & die de- signs. By rotating the tooling in relation to the material flow, a rotary head in- creases the wall strength of an extrusion, thereby allowing a thinner wall with less material and the corresponding cost sav- ings for the user. Typical applications for rotary heads include medical and multi- lumen tubing plus various high-end ex- trusions with interlocking layer or multi- ple striping requirements. Features offered on these new rotating extrusion dies include counter-rotating tip & die, co-rotating tip & die, rotating die with conventional tip, rotating tip with conventional die, crosshead or in- line, multi-layer, striping, certain profiles and optional quick-change cartridges that minimize cleaning downtime. By using rotary dies, extruders can realize a cost savings due to the elimination of secondary processes, cosmetic enhance- ment of the end product with the elimina- tion of weld or parting lines, plus reducti- on or complete elimination of ovality. Guill Tool offers its new high-speed rota- ry models as turnkey packages, complete with die cart, tools and all accessories for installation and maintenance. „The Bullet™“ Extrusion Head n Guill Tool introduced The Bullet ® in 2015, a new extrusion head with fixed center design, multi-port spiral flow de- sign and gum space adjustment, plus the added feature of no fastening hardware, so cleaning and restart are easier and Rotary Extrusion Dies with 2X Increase in Speed pending CAM LOCK ® deflector retaining system offers these additional benefits to extruders and machine builders: • It only takes ½ 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 The head on cart The Bullet, showing the absence of hardware, i.e. nuts and bolts, so disas- sembly, cleaning and restart are made easier
