Feb. 20, 2026 — Guill Tool, a global leader in extrusion tooling, introduces the latest generation of its Series 800, the 2-to-6 layer extrusion tooling designed to produce the highest quality, highest material-efficient 1/8” to 6” OD tubing for automotive, medical, appliance and industrial applications. The redesigned Series 800 produces flawlessly smooth extrusion and layer definition of Fluropolymer and other materials for all multi-layer, multi-lumen medical tubing, as well as fuel line constructions, multi-layer PEX pipe and drip irrigation applications, among others. The Guill design further allows thin layer combinations of polymers and adhesives to .02mm or less.
Guill offers its extensive line of Series 800 crossheads and inline tubing dies in fixed and adjustable center, for single or co-extrusion applications. The tooling is designed to process virtually all compounds and features a 2-stage concentricity adjustment system which isolates the tooling from the high pressure portion of the system, allowing for easy concentricity adjustment without the need to shut down the line. Guill also offers its unique Bow-Tie distribution system, which allows for compact and easy-to-swap flow components, even in higher layer count applications.
All Guill tooling is produced with rigorous computer simulation of the flow channels using Computational Fluid Dynamics (CFD) programs, resulting in optimum uniform flow with no weld lines.
