Extrusion die maker Guill Tool & Engineering (West Warwick, RI) featured its extensive line of crossheads and inline tubing dies in fixed and adjustable centers for single or co-extrusion applications at the recent NPE2015 trade show. The tooling is designed to process all compounds, and features the company's patented, precision Feather Touch Concentricity adjustment and Seal Right system, which combines with the Feather Touch system to eliminate polymer leaking. Guill also displayed its unique spiral flow distribution system.
Guill also introduced the latest generation of its Series 800 two- to six-layer extrusion tooling designed to produce high-quality, material-efficient 1/8- to 6-in.-OD tubing for automotive, medical and industrial applications. The redesigned Series 800 produces flawless extrusion and layer definitions of fluoropolymer and other materials for all fuel line, multi-layer PEX pipe and drip irrigation applications, the company claims. The Guill design further allows thin layer combinations of polymers and adhesives to 0.02 mm or less.
According to the company, all Guill tooling is produced with rigorous computer simulation of flow channels using computational fluid dynamics programs, resulting in optimal uniform flow with no weld lines.
