Extrusion International 3-2024

26 Extrusion International 3/2024 NPE2024 New Rotary Die and Cam Lock Design Featured at NPE Guill Tool unveiled new, simpli - fied designs for its cam lock feature and rotary die at NPE 2024. The new rotary head offers a simplified design, while the cam lock will now be available on additional heads besides the Bullet. The cam lock is the same as sup- plied on the Bullet and will be sup- plied on additional heads, where applicable. It allows quick and easy assembly and disassembly of the crosshead and eliminates the socket head caps screws. By removing and replacing the internals, a different profile can be extruded in minutes rather than hours. Since the cam lock resets the internals in the right configuration every time, there's far less chance of error, compared to the assembly and misalignment issues with socket set screws. The cam lock offers several features such as: it takes only ½ turn to remove and install the deflector tip and no fastening hardware is required. Ad- ditional features include fast tool changes (threaded retaining ring for the die and threaded tip retain- er), dies remove from the front and tips from the back, tooling retainers for gum space adjustment, vacuum connections, simplified cleaning and reduced downtime and operat- ing costs. Guill’s new rotary head is a sim- plified design compared to its pre - vious models. By rotating the tool- ing in relation to the material flow, a rotary head increases the wall strength of an extrusion, thereby allowing a thinner wall with less material. Features include only ro- tating the die, randomizing any gauge bands or thickness varia- tions and in some cases, improv - ing material properties of the end product. Various sizes of tubing can easily be accommodated with the unique Guill cam-lock design that radically reduces set-up and changeover times. Extruders can realize a cost sav- ings due to the elimination of sec- ondary processes, cosmetic en - hancement of the end product with the elimination of weld or parting lines, plus reduction or complete elimination of ovality. Typical applications for rotary heads include medical and multi- lumen tubing plus various high-end extrusions with interlocking layers or multiple striping requirements. Corrugated Tube Crossheads and Dies Guill Tool offers their pat- ent pending extrusion tooling, Series 400. It’s adaptable to a wide variety of corrugated equipment and mold. The Series offers a host of benefits for OEMs, as well as for automotive and medical applications. The unique tooling includes the multi-port spiral flow design that provides a balanced compound dis- tribution with no weld lines to the corrugator. The elimination of weld lines significantly increases the finished product’s over - all strength. Models offered include 420, 423, 432 and 434. Features of the 400 Series in- clude Spider- less Inline, fixed center or adjust- able, built in cartridge heaters, adjustable gum space, low inventory, expandable to multi-layer, heated core pin and one-piece body/flow diverter. Since there are no spider lines, there’s room for more air and no cold legs. Most products should be fixed. Users can change only one component and become fully ad- justable. The cartridge heaters offer evenheat for better flowand ensure there aren’t any cold spots. More control of product size is achieved with adjustable gum space. Low inventory results in no burning or stagnation-quick color change. Due to the fact that it’s expandable to multi-layer, the crossheads run a va - riety of products. Lastly, benefits of the heated core pin and one-piece body/flow diverter are better tem - perature control and easy cleaning- quick changer, respectively.
