On the new reciprocating head developed by Guill Tool, W. Warwick, R.I.., the typical tip and die assembly is replaced with a linear reciprocating assembly that changes the tube’s profile on the fly within a given length. This process is repeated throughout a single extrusion run without interruptions. As a result, only one extrusion run is needed to produce a finished product, as opposed to multiple runs requiring tooling changes and manual assembly operation to connect different tubing shapes. Guill’s new reciprocating head also eliminates in-process inventory. As a result, there is no need for storage of various tubing shapes and connectors needed for assembly, fulfillment of orders, and replenishment of finished goods.

Moreover, the reciprocating head eliminates a connecting piece, allows JIT production and products made-to-order, and reduces total run time from receiving the order to shipping, according to Guill.


  • Extrusion Troubleshooter

    Extrusion is a "black-box" process. We can't see what goes on inside an extruder, so we depend on instruments. We need to be sure that all sensors are working and readouts are calibrated correctly.

  • What About Melt Strength?

    All extrusion processes depend to some degree on the melt strength of the polymer, and this property is generally a no-show on data sheets.

  • PBT & PET Polyester: Part 2 The Performance Factor

    All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.
