Extrusion Asia Edition 2-2024

19 Extrusion Asia Edition 2/2024 for faster and easier cleaning and changeover. The new 500 Series also features the latest Center-Stage concentricity adjust- ment system that significantly reduces pressure on the tooling, allowing easier and more precise concentricity adjust- ments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple replacement of locked or damaged adjusting bolts, which fur- ther saves on repair and downtime. Another innovative feature of this new rubber/silicone crosshead is a cast alumi- num 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 tradi- tional integrated 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 materials are being processed. This leads to lower head pressures allowing the material to move through the head in a much more balanc- ed and even flow. All crossheads supplied by Guill are fur- nished with a tool kit for assembly and disassembly as well as a detailed opera- tor’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the new 500 series crosshead.

This se- ries of blow molding ex- trusion dies, features a core diameter between 8.5” (219.5 mm) to 10” (254.0 mm). Model 1025 uses material blends which are ideal for medi- cal, automotive and spe- cialty packaging. Series 1000 is available as single layer, co-extrusion or triple extrusion. It adapts to existing extru- der layout and in most cases, accepts existing tooling. Features include fixed center or adjustable, built-in cartridge heaters, low inventory, expanda- ble to multi-layer, heated core pin, one- piece body/flow diverter and split feed balanced flow. Most products should be run fixed. Users need to change only one component to become fully adjustable. The cartridge heaters offer even heat for better flow and ensure there aren’t any cold spots. Low inventory produces no burning or stagnation, resulting in quick color change. Since it’s expandable to multi- layer, the crossheads run a variety of products. Benefits of the heated core pin and one-piece body/flow diverter are bet- ter temperature control and easy cleaning/quick change over, respectively. Lastly, the split feed balanced flow achiev- es concentric walls at all speeds. 吹塑模具 / Blow Mold
