Guill Tool & Engineering has introduced a new single-point concentricity extrusion crosshead that uses micro-fine adjustment screws for precise concentricity adjustment.

Guill presents single-point concentricity extrusion tooling
The precision of concentricity reaches 0.008” or finer per revolution. This single-point concentricity adjustment is a unique Guill innovation for the extrusion of thin-walled jacketing and precision ID/OD tubing. One adjustment bolt controls 360 degrees of adjustment.
Features of the single-point crosshead include a patented cam-lock deflector for quick changeovers, with a residence time of one minute at 0.5 lb/hr (~227g) material flow, optimised usage with extruders, and a max die ID of .250”.
Additionally, the Guill single-point crosshead offers great flexibility. It not only accepts both vacuum and micro-air accessories, but is suitable for pressure and sleeving applications. Fluoropolymer designs are available upon request.
