Extrusion 8-2019

55 Extrusion 8/2019 Extrusion Tooling New design of rotary inline or crosshead dies feature speeds to 1000 RPM G uill 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 running to 1000 RPM depending on the applica- tion, are now available in the Guill line of patented rotating tip & die designs. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of an extrusion, thereby allowing a thinner wall with less material and the cor- responding 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, cross- head 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 installation and maintenance. G uill introduces the latest generation of its Series 800 , the 2-to-6 layer extrusion tooling designed to produce the highest quality, highest material-efficient 1/8” to 6” OD tubing for automotive, medical, appliance and industrial applications. The redesigned Series 800 produces flawlessly smooth extru- sion and layer definition of Fluropolymer and other materials for all multi-layer, multi-lumen medical tubing, as well as fuel Rotary Extrusion Dies with 2X Increase in Speed line constructions, multi-layer PEX pipe and drip irrigation appli- cations, among others. The Guill design further allows thin lay- er combinations of polymers and adhesives to .02mm or less. Guill offers its extensive line of crossheads and inline tubing dies in fixed and adjustable center, for single or co-extrusion applications. The tooling is designed to process all compounds and features the company’s patented, precision Feather Touch Concentricity adjustment, the Seal Right System, which com- bines with the Feather Touch system to eliminate polymer leak- ing. Guill also offers its unique spiral flow distribution system. All Guill tooling is produced with rigorous computer simulation of the flow channels using Computational Fluid Dynamics (CFD) programs, resulting in optimum uniform flow with no weld lines.
