Guill Tool & Engineering has introduced a new 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 Guill innovation for the extrusion of thin-walled and precision ID/OD medical tubing. One adjustment bolt controls 360° of adjustment.
Features of the Micro Medical crosshead include a patented cam-lock deflector for quick 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 new crosshead offers flexibility to its users — it accepts both vacuum and micro-air accessories and is ideal for pressure and sleeving applications. Fluoropolymer designs are also available.
