Crosshead Offers Precise Concentricity Adjustment
Medical crosshead features patented single-point concentricity adjustment.
The Micro Medical extrusion crosshead from Guill Tool & Engineering uses micro-fine adjustment screws for precise concentricity adjustment. The precision of concentricity reaches 0.008-in. or finer per revolution, according to Guill.
Guill says this single-point concentricity adjustment is a unique 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 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 Micro Medical crosshead is said to offer 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.
