Ease of Use

Adjustable or Fixed, Tip or Die

We offer a number of methods for adjusting concentricity to maximize the desired amount of pressure applied to a substrate between the tip and die. With our heads you can make the adjustment to the Gum Space, Tip or Die.

New to our line is our Single Point Adjust, with one bolt you are able to control 360° of adjustment. Read more below.

Guill Extrusion Head with One Touch Concentricity Adjustment

Precise Concentricity Adjustment

Our new Single Point Adjust offers  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 and precision ID/OD medical tubing. One adjustment bolt controls 360° of adjustment. Our Single Point Adjust is available on new Crossheads up to 1.250″ Die ID and is retrofittable to most Guill crossheads. We also have Fluoropolymer designs available.

FeatherTouch™ Adjustment

Adjustable Die Holder System

We offer the patented FeatherTouch™ adjustable die holder system for precision concentricity adjustment using a small 6-inch wrench. The die holder with the end cap fully tightened requires little pressure to make adjustments. The FeatherTouch™ cartridge system of components is assembled at Guill and requires no further attention or maintenance.
