Guill Tool unveiled its new, simplified designs for its cam lock feature and rotary die at NPE 2024 in Orlando, Florida.
The cam lock is the same as supplied on the Bullet and supplies 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. Additional features include fast tool changes (threaded retaining ring for the die and threaded tip retainer), dies remove from the front and tips from the back, tooling retainers for gum space adjustment, vacuum connections, simplified cleaning and reduced downtime and operating costs. mounting screws
Guill’s new rotary head is a simplified design compared to its previous models. 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. Features include only rotating the die, randomising any gauge bands or thickness variations and in some cases, improving 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 realise 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. Typical applications for rotary heads include medical and multi-lumen tubing plus various high-end extrusions with interlocking layers or multiple striping requirements.
