Crosshead Die Features Single-Point Concentricity Adjustment
One adjustment bolt controls 360° of adjustment.
Guill Tool & Engineering has introduced an extrusion crosshead that uses micro-fine single-point adjustment screws for precise concentricity adjustment. The precision of concentricity reaches 0.008 in or finer/revolution. This single-point concentricity adjustment is reportedly 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 patented cam-lock deflector for quick changeovers, with a residence time of one minute at 0.5 lb/hr material flow, optimized usage with extruders measuring ½ in. and ¾ in., and a max die ID of 0.250 in.

Additionally, the Guill single-point crosshead offers great flexibility to its users. It not only accepts both vacuum and micro-air accessories, but is also ideal for pressure and sleeving applications. Fluoropolymer designs are available upon request.
