Extrusion tool manufacturer Guill Tool & Engineering has introduced a new single-point concentricity extrusion crosshead that uses micro-fine adjustment screws for precise concentricity adjustment.
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° of adjustment.
Features of the single-point crosshead include a cam-lock deflector for changeovers, with a residence time of one minute at .5 lb/hr material flow, optimised usage with extruders measuring ½” and ¾”, and a max die ID of .250.
The Guill single-point accepts both vacuum and micro-air accessories, and can be used for pressure and sleeving applications. Fluoropolymer designs are available upon request.
