Extrusion 6-2024

Extrusion 6/2024 lowing for faster and easier cleaning and changeover. The new 500 Series also features the latest Center-Stage concentricity adjustment system that significantly reduces pressure on the tooling, allo- wing easier and more precise concen- tricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow 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 Guill Tool introduces the NEW 500 Series crosshead with MAGS gum space adjustment. The 500 Series is designed specifically for the flow cha- racteristics and unique processing challenges of elastomeric com- pounds. One of the key features engi- neered by Guill on this new crosshead design is the mechanically assisted gum space (MAGS) adjustment sy- stem. This new method of gum space adjustment allows the operator to make an effortless adjustment from a single point using a common socket wrench. No more need to struggle with multiple nuts and bolts in order to adjust gum space, which leads to faster adjustments. The visual indica- tor on the core tube allows the opera- tor to see how far the gum space has been moved, making those adjust- ments much more accurate and re- peatable. 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 automati- cally extract the deflector from the head body, which is another time saver. Also, with no undercuts on the deflector, there are no material hang- ups when extracting the deflector, al- NEW 500 Series Rubber/Silicone Extrusion Crosshead 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 in- tegrated cooling systems. The new 500 Series crosshead with MAGS gum space adjustment 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 reduces the shear and heat that is generated as the ma- terials are being processed. This leads to lower head pressures 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 operator’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the new 500 series crosshead.
