Extrusion International 3-2019

29 Extrusion International 3/2019 The hardware-free and patented cam lock design of the NEW 500 Series from Guill means no time is wasted un- bolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is re- quired to loosen and automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the deflector, there are no mate- rial hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover. The new 500 Series also features the latest Center-Stage concentricity adjustment system that significantly re- duces pressure on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also al- low simple replacement of locked or damaged adjusting bolts, which further saves on repair and downtime. Another innovative feature of this new rubber/silicone crosshead is a cast aluminum liquid-fed cooling sleeve that allows the user to switch out the cooling jacket in the event of a line obstruction, again reducing downtime compared to traditional integrated cooling systems. The new 500 Series crosshead with MAGS gum space ad- justment is a drop-in replacement 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 re- duces the shear and heat that is generated as the mate- rials are being processed. This leads to lower head pres- sures allowing the material to move through the head in a much more balanced and even flow. All crossheads supplied by Guill are furnished with a tool kit for assembly and disassembly as well as a detailed op- erator’s instruction manual.

The 500 Series is designed specifically for the flow characteristics and unique processing challenges of elastomeric compounds. One of the key features engineered by Guill on this new crosshead design is the mechanically assisted gum space (MAGS) adjustment system. This newmethod of gum space adjustment allows the operator tomake an effortless adjustment from a single point using a common socket wrench. Nomore need to struggle withmultiple nuts and bolts in order to adjust gum space, which leads to faster adjustments. The visual indicator on the core tube allows the operator to see how far the gum space has beenmoved, making those adjustments muchmore accurate and repeatable Guill Series 500 crossheadwithMechanically AssistedGumSpace (MAGS) adjustment, specially designed for theflowcharacteristics of elastomeric compounds EXTRUSION TOOLING
