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 de- Guill Tool introduced the NEW 500 Se- ries crosshead with MAGS gum space adjustment. 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 as- sisted gum space (MAGS) adjustment system. 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 indicator on the core tube al- lows 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 automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the de- flector, there are no material hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover. The new 500 Series also features the lat- est Center-Stage concentricity adjust- New 500 Series Rubber/Silicone Extrusion Crosshead sign or line layout. The addition of a newly designed flow inlet channel reduc- es 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 fur- nished with a tool kit for assembly and disassembly as well as a detailed opera- tor’s instruction manual.

Genau auf diese Bedürfnisse abge- stimmt ist die von Bürkert Fluid Control Systems entwickelte, modular aufgebau- te Plattform für die Temperier-Regelung, die sich optimal an unterschiedlichste Prozesse anpassen lässt. Die Basis dafür bilden eine breite Palette an elektromo- torischen und pneumatischen Ventilen In vielen industriellen Prozessen der Metall- und Kunststoffverarbeitung kommt es auf die exakte Temperaturfüh- rung an. Dabei können die Anforderun- gen an die Temperier-Regelung je nach Produktionsbedingungen erheblich vari- ieren. Immer sind jedoch Lösungen ge- fragt, die – um eine hohe Produktquali- tät sicherzustellen – mit möglichst hun- dertprozentiger Reproduzierbarkeit ar- Prozesstemperaturen zuverlässig regeln sowie verschiedene Messprinzipien, zum Beispiel für Kühlmittel-Durchflüsse (Ul- traschall und Flügelrad), Luftmengen (thermischer Sensor) sowie Druck und Temperatur. Ausgeliefert als individuell aufgebautes Komplettsystem ist die Tem- perier-Regelung dann einfachst in die unterschiedlichsten Anwendungen inte- grierbar. Dank der modularen Bauweise lassen
