Extrusion Asia Edition 1-2021

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 over- all unit design enables faster disassembly, proper cleaning and restart, allowing the line to become more profitable, more quickly.

The traditional tip and die assembly is replaced with a linear reciprocating assembly that changes the tube’s profile within a given length. This process is repeated throughout a single extrusion run without interrup- tions. Cutting capability, in association with the extrusion speed, cuts the finished product to length. While cost and value stream activities are reduced, quality is im- proved. Only one extrusion run is needed to produce a finished product, as opposed to multiple extrusion runs with tooling changes along with a manual assembly operation to connect different tubing shapes. Guill’s new reciprocating head elimi- nates an assembly operation. It also eliminates in-process in- ventory. Thus, there is no need for storage of various tubing shapes and connectors needed for assembly, fulfillment of or- ders and replenishment of finished goods. Furthermore, the reciprocating head eliminates a connecting piece, allows JIT production and products made-to-order. Lastly, it reduces total run time from receiving the order to shipping.
