New low-volume spiral flow ABA crosshead with 2-stage clamping for easy concentricity adjustment
Guill Tool introduces Series 824, a co-extrusion crosshead designed for irrigation tubing with an emitter tool. Manufactured from stainless steel, this new crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds. Dual feed ports provide concentric compound flow, while the splits flow from one extruder to feed the inside and outside layers via a manifold assembly. Series 824 is adaptable to all popular extruders on the market currently.
Capacities include a max. die ID of 1.875”, max. core OD of 1.250”, max. tip OD of 1.500” and max. emitter tool OD of 30mm (1.18”). The Series 824 design allows the emitter insertion tool to pass completely through the crosshead ID. Gum space adjustment is performed with die nut rotation, while the Guill 2-stage clamping mechanism allows easier concentricity adjustment. Quick-change tooling and a tool kit for disassembly and re-assembly are provided with the unit.
Bill Conley, sales manager for Guill, comments, “On this project, the customer challenged us with an application that required precise placement and bonding of preformed emitters within the extruded tubing without melting them in the crosshead. It was also necessary to process either a low-cost ABA layer construction or single-layer construction within the same unit.”
With the Series 824, the customer realized cost reductions, better quality, less scrap and more uptime in their process. The Guill cool-tube design prevented the emitter from melting in the head and the overall unit mechanics allowed more rapid and easier changeover from a co-extrusion to a single layer.
On this project, Guill also supplied the customer the company’s extrusion tool cart, which facilitates easy alignment and tool changes. The removable cart swing gates stay free from accumulated process fluids, while the adjustable height means the cart is compatible with virtually any extruder model. Thermal isolation in the design keeps heat in the head, not the cart.

New extrusion head from market leader features NO hardware, for easy cleaning, plus quick-change tooling, as tips removes from the back, die from the front
Guill Tool introduces The Bullet™, a new extrusion head with fixed center design, multi-port spiral flow design and gum space adjustment, plus the added feature of no fastening hardware, so cleaning and restart are easier and faster than any conventional head on the market currently, according to company sources.
The Bullet allows quick tooling changes, as the tips remove from the back and the die removes from the front of the unit. The absence of fastening hardware eliminates leaking, as does the taper body and deflector design pioneered by Guill.
High- and low-volume applications are suitable for this head and are accommodated with the simple, easy changing of just one component. A family of crosshead designs is available and users can specify the “caliber”, that is, the max. die ID.
A vacuum chamber and kit for assembly and disassembly are included with the unit. Optional keyed tooling capability offers machine designers and end users quick orientation, so the overall unit design enables faster disassembly, proper cleaning and restart, allowing the line to become more profitable.
