Extrusion International 3-2022

25 Extrusion International 3/2022  Guill Tool introduced the new 500 Series crosshead with MAGS gum space adjustment. The 500 Series is designed specifcally for the flow characteristics and unique process - ing 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 new method of gum space adjustment allows the operator to make an effortless adjustment from a sin- gle 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 in- dicator on the core tube allows the operator to see how far the gum space has been moved, making those adjustments much more accurate and repeatable. 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 au- tomatically 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 deflec - tor, allowing for faster and easier cleaning and changeover. The new 500 Series also features the latest Center-Stage concentricity adjustment system that signifcantly reduces pressure on the tooling, allowing easier and more precise concentricity adjustments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple re- placement of locked or damaged adjusting bolts, which fur- ther saves on repair and downtime. Another innovative feature of this new rubber/silicone cross- head 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 tra- ditional integrated cooling systems. The new 500 Series crosshead withMAGS gum space adjust- ment is a drop-in replacement on most existing NRM lines, however this crosshead design can also be adapted to ft 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 materials are being processed. This leads to lower head pressures allow- ing 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 instructionmanual. The engineering teamat Guill will gladly assist users in the implementation and operation of the new 500 series crosshead.

The new IDX internal diameter HVOF coating provides a high-performance tungstencarbidenanocoatingfordia- meters as small as 3-in, lengths up to 8 ft, and thicknesses up to 0.015 of an inch. The thermal spray system – con- sisting of a delivery mechanism and coating material – provides a tung- sten carbide, cobalt chrome coating which delivers exceptional abrasion resistance and three times the service life of chrome-plated parts. “The IDX system meets the industry’s growing demand for abrasive, corro- sive, and aggressive processing in small- inside diameter applications,“ said Scott Caplan, Executive Vice President, Ex- treme Coatings. “Thismajor technology advancement enables us to keep pace with other performance improvements in the downhole drilling industry.“ The internal diameter HVOF coating is also corrosion resistant and crack free. It is 99% porosity-free and superior to white iron, chrome plated, or other ID surface engineered option coatings. The IDX system is targeted for a range of oil and gas applications including hous- ings, cylinders, bushings, sleeves, me- chanical seals, and hydraulic cylinders.
