New extrusion crosshead for medical tubing ensures precise concentricity

Guill Tool & Engineering (West Warwick, RI) showcased its new extrusion crosshead that uses micro-fine adjustment screws to achieve precise concentricity at last week’s co-located MD&M West and PLASTEC West event in Anaheim, CA. The Micro Medical crosshead achieves a concentricity precision of 0.08 inches or finer per revolution. The single-point concentricity adjustment is a Guill innovation for the extrusion of thin-walled and precision ID/OD medical tubing, said the company. One adjustment bolt controls 360° of adjustment.

The next rendezvous for the medical device supply chain happens in Cleveland, OH, on March 29 and 30, 2017. UBM America’s newest design and manufacturing trade show and conference, Advanced Design & Manufacturing (ADM) Cleveland showcases five zones—medical manufacturing, plastics, packaging, automation and robotics, and design and manufacturing. Numerous conference sessions are targeted to the medical manufacturing, automotive and other key industry sectors. Go to the PLASTEC Cleveland website to learn more and to register to attend.

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 and ¾ inches, and a maximum die ID of 0.250 inches. 

Additionally, the crosshead accepts both vacuum and micro-air accessories, and is suited for pressure and sleeving applications. Fluoropolymer designs are available upon request.
