in the event of a line obstruc- tion, again reducing down- time compared to traditional integrated cooling systems. The NEW 500 Series cross- head with MAGS gum space adjustment is a drop-in re- placement on most existing NRM lines, however this crosshead design can also be adapted to fit any extruder design or line layout. The addition of a newly designed flow inlet channel reduces the shear and heat that is generated as the materials are being processed. This leads to lower head pressures allowing the material to move through the head in a much more balan- ced and even flow. All crossheads supplied by Guill are fur- 65 Extrusion 5/2022 ➠ Guill Tool & Engineering Co., Inc. www.guill.com The hardware-free and patented cam lock design of the NEW 500 Series from Guill means no time is wasted unbolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is required to loosen and automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the de- flector, there are no material hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover. The NEW 500 Series also features the lat- est Center-Stage concentricity adjustment system that significantly reduces pressure on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple replacement of locked or damaged ad- justing bolts, which further saves on re- pair and downtime. Another innovative feature of this new rubber/silicone crosshead is a cast alumi- num liquid-fed cooling sleeve that allows the user to switch out the cooling jacket Guill Series 500 crosshead with Mechanically Assisted Gum Space (MAGS) adjustment… specially designed for the flow characteristics of elastomeric compounds n Guill Tool announces a new design for its high-production ro- tary models, both inline and crosshead style. A 2X increase in speed, with models running to 1000 RPM depending on the ap- plication, are now available in the Guill line of patented rotating Rotary Extrusion Dies with 2X Increase in Speed tip & die designs. By rotating the tooling in relation to the ma- terial flow, a rotary head increases the wall strength of an ex- trusion, thereby allowing a thinner wall with less material and the corresponding cost savings for the user. Typical applications for rotary heads include medical and multi-lumen tubing plus various high-end extrusions with interlocking layer or multiple 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 inline, 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 enhancement of the end product with the elimination of weld or parting lines, plus reduction or complete elimination of ovality. Guill Tool offers its new high-speed rotary models as turnkey packages, complete with die cart, tools and all accessories for in- stallation and maintenance. Head on cart nished with a tool kit for assembly and disassembly as well as a detailed opera- tor’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the NEW 500 series crosshead.
