26 Extrusion International 1/2021 EXTRUSION TOOLING While cost and value stream activities are reduced, quality is improved. Only one extrusion run is needed to produce a fi nished product, as opposed to multiple extrusion runs with tooling changes along with a manual assembly op- eration to connect different tubing shapes. Guill’s new reciprocating head eliminates an assembly operation. It also eliminates in-process inventory. Thus, there is no need for storage of various tubing shapes and connectors needed for assembly, ful fi llment of orders and replenish- ment of fi nished goods. Furthermore, the reciprocating head eliminates a con- necting piece, allows JIT production and products made- to-order. Lastly, it reduces total run time from receiving the order to shipping. New 500 Series Rubber/Silicone Extrusion Crosshead Guill Tool introduces the NEW 500 Series crosshead with MAGS gum space adjustment. The 500 Series is designed speci fi cally for the fl ow 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 indicator on the core tube allows the operator to see how far the gum space has been moved, making those adjust- ments 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 un- bolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is re- quired to loosen and automatically extract the de fl ector from the head body, which is another time saver. Also, with no undercuts on the de fl ector, there are no mate- Reciprocating Head introduced – Automated Extrusion Process Drastically changes the Extruded Profile Guill Tool has released its new reciprocating head. The traditional tip and die assembly is replaced with a linear reciprocating assembly that changes the tube’s pro fi le within a given length. This process is repeated throughout a single extrusion run without interruptions. Cutting capability, in association with the extrusion speed, cuts the fi nished product to length
